Trust only Graco repair parts for Fusion guns
When choosing repair parts for your Fusion® gun, it’s important to consider the testing that is involved in the manufacturing process. Graco’s commitment to high quality products holds true at the Sioux Falls manufacturing facility where Fusion AP guns and repair parts are produced.
Comprehensive testing is conducted on parts produced in a Graco facility. As for the Fusion product line, mix chambers are 100% fluid tested prior to shipment to ensure proper pattern and sealing capability. Additionally, O-rings are chemical-tested to ensure compatibility with chemicals used in guns. Most importantly, full statistical process capability studies are completed on components to help ensure manufacturing processes are capable of consistently producing high quality parts that meet or exceed design requirements.
Eric Rennerfeldt, Graco Worldwide Product Manager said, “I was amazed at our production ability and commitment to quality at the gun plant.”

Winter blend foams
Let it snow, let it snow, let it snow! Many regions of the country have seen a record amount of snowfall in 2010. The roof of the Metrodome collapsed and the New York Giants have been stranded not once, but twice, due to weather. So what does this have to do with spray polyurethane foam?
Now that its colder, considerations should be made when choosing spray foam. The first consideration during cold temperatures is the necessity for A and B components to be stored between certain temperatures. Included in this consideration is the need for foam to be kept warm before and during use. To understand the optimal range for the materials you are working with refer to the MSDS’s and product specifications provided by the manufacturer.
In addition to the temperature of the spray foam, consider the temperature of the substrates. A cold substrate will adversely affect the foam rising action as energy typically used to create yield is reallocated to heating the target. Jim Anderson, Manager, Applications & Training for BASF, recommends applying a light layer of foam, otherwise known as a flash coat, to help neutralize the “heat sink” effects of a target. This flash coat introduces heat to warm up the interior to help regain foaming efficiency and yields.
Manufacturers also produce a variety of foams for a wide range of applications, including specific types of foam made for colder temperatures. These special formulas modify the catalyst or B compound to increase the chemical reaction and increase the foam rising action for better performance in colder temperatures.
Ultimately, each application needs to be assessed to consider the factors in this article as well as many others. Refer to the latest published information such as manufacturers guidelines, technical specifications, industry publications and application instructions to find the best solution for you and your customers.

Graco announces Reactor® product improvements
Graco recently made some product enhancements to the Fluid Temperature Sensor, and to the immersion heaters used on all Electric and Hydraulic Reactor fluid heaters. Improvements to both products involve using fewer parts and simplifying the design in order to reduce possible issues and leak points.
Fluid Temperature Sensor (FTS)
Graco eliminated additional fittings that were necessary to install the FTS in-line with Reactor heated hoses. Now, the metal bodies of both the molded FTS and the FTS spacer are machined with the proper thread connections. One side of the FTS is machined with a female JIC thread and the other side with male JIC threads. No changes were made to the thread type or to the hose fittings. The changes to the FTS are retro-fittable to all hoses in the field. The easiest way to install the new FTS is to attach the male hose end to the FTS first, then install the female hose end to the FTS.
Graco has also changed the molding process used on the FTS. The new FTS has a cleaner, more aesthetically finished look, including the Graco logo molded into the part.
Immersion Heaters
The immersion heaters used on all Reactor fluid heaters have been changed from a two-piece design to a one-piece design. The old design required a fitting reducer nut, which included an o-ring, to be used with each immersion heater.
The new design eliminates the need for a fitting reducer nut by incorporating the reducer nut as part of the immersion heater saving time and money on maintenance. No changes were made to the thread type used on the fluid heater block. This change is retro-fittable to all fluid heaters in the field.
To install the new immersion heater into a fluid heater block currently using the old style immersion heaters, the fitting reducer nut must be removed from the fluid heater block before installing the new immersion heater.
A summary of old and new immersion heater parts numbers is as follows:

What am I forgetting?
By Barry Taft, Graco Technical Assistance
How to prepare your spray foam equipment for long-term storage
Ever walk away and wonder, “I know I’m forgetting something?” This article will tell you what to consider at the end of the season before walking away.
If you are leaving your foam or coating equipment idle for more than three or four weeks, it is important to flush the reactive material out of the machine and purge it with a quality storage fluid. Every spring the Technical Assistance group gets many calls on how to clear a solidified ISO in the hose, gun, or proportioner equipment. Replacing the hose line because of improper flushing and storage is an expensive undertaking in both hose replacement cost and labor when you are trying to get up and running the following season.
To properly flush your equipment, you must contact your chemical supplier to select the proper urethane grade solvent that will not react with their formulation. Typically it will be a Glycol Ether based solvent, completely moisture-free. Believe it or not, Graco gets several calls each year related to proper flushing fluid – wondering if they can use some concoction their friend or brother-in-law said will work great for this purpose from MEK to transmission fluid to Mr. Bubble and water. While all these chemicals will not affect the equipment-wetted parts, they will react to isocyanate used in most foam and coating material formulations. What ever you use, you must be sure to properly dispose of chemicals in accordance with local jurisdiction requirements and to follow proper safety precautions while flushing.
When flushing your equipment, you should pull all filters and screens and place your feed pumps into the flush solvent. Next, cycle the proportioner pumps to agitate the material through the system until the solvent runs clear. Be sure to properly mark our waste container to not mix the “A” with “B” material, as they will still react at a diluted state. Wash all screens separately and re-install after flushing. After the system has run clear and you are sure of adequate flushing, chase the flush material out with a storage fluid. Common storage fluid is again completely moisture-free and typically a plasticizer that will not gel or react with any trace chemical left in the system. Graco TSL “Throat Seal Liquid”, DOP (Dioctyl Phthalate) or other commercially available plasticizers are commonly used. The key here is that it’s completely moisture-free.
After filling the pump with storage fluid, it would be a good time to stall the proportioner at 1000 psi (7 MPa) (69 bar) fluid pressure and examine the entire system for any packing leakage or loose fittings that should be addressed. It’s also a good time to correct any situations that may have arrived when you were just too busy working.
You may wish to consider general maintenance items such as replacing hydraulic oil and filter if required, and cleaning and replenishing the ISO pump lubrication system. Check to see if the drive belt is in good condition, check for any loose electrical connections, inspect the motor brush as well as the feed pump and supply line strainers. Do a general inspection of the heated line – checking the electrical and fluid temperature sensor connections, and making sure there’s no ripped insulation. You should also properly service the spray gun and feed pump, and any auxiliary equipment.
End of season maintenance is crucial before you walk away at the end off the spray season, or before the next job comes along. Remember, a little effort now will save time, money, and frustration later.

Graco® Reactor® used in World Trade Center project
Airseal Insulation Systems of Brooklyn, NY used a Graco Reactor E-30 to apply spray polyurethane foam (SPF) to help build One World Trade Center in New York City, according to a recent article in SprayFoam magazine.
Because of critical deadlines, the concrete for One World Trade Center needed to be poured in sub-freezing weather. The forms needed to be insulated or the concrete wouldn’t cure properly. Using Graco equipment, Airseal Insulation Systems insulated the concrete form for the core shaft of the building. Read more

Reactor® E-Series now offers adjustable pressure offset
Graco® now includes the adjustable pressure imbalance feature on electric Reactors (models E-20, E-30, E-XP1, E-XP2), a feature that was previously only available on hydraulic Reactors (models H-25, H-40, H-50, H-XP2, H-XP3). The pressure imbalance function (status code E24) detects conditions that can cause off-ratio spray, such as loss of feed pressure/supply, pump seal failure, clogged fluid inlet filter, or a fluid leak.
The pressure imbalance default is factory-set at 500 psi (35 bar, 3.5 MPa). This change allows the pressure to be adjusted and set at 100 to 999 psi in 100 psi increments. Values less than 500 would be selected for tighter ratio error detection, while higher values would be selected for looser detection or to avoid nuisance alarms.

Pressure imbalance: “The Gun & Gauges Don’t Lie”
By Barry Taft
In this issue, I would like to take a look at pressure imbalance issues such as an E24 indication in the Reactor® Series or analog gauges reading high or low in other proportioner platforms.
There are many causes for pressure imbalance and we need to focus our attention to the correct area to get us back up and running. I like to say there is no money in machine repair down time. So instead of a “shotgun” approach where you clean every filter, clean the gun, replace mix chambers, swap guns and feed pumps and still can’t find the root of the problem, I propose a more focused approach where we listen to what our guns and gauges are telling us.
A very good friend of mine, Craig Hier with Intech Equipment & Supply liked to call it “The Rookie Rag” approach. This is a great way to teach the concept. If we can determine which chemical – “A” or “B” – is coming out of the gun, then we can place a rag over that side’s gauge and focus on the other side where the problem lies. This will immediately save us time by focusing on the side that is lacking chemical or is the cause to our problem. That said, let’s explore some of the common causes for a pressure imbalance situation.
First, we need to understand that the restriction of the mix chamber impingement port sizing creates the backpressure that we monitor at the fluid outlet gauges. Think of it as blocking the end of the garden hose. The more we block, or “restrict” the opening, the greater the backpressure we create. Most polyurethane foam chemistry requires 1:1 by volume ratio and pressures balanced within +/- 200 psi or so to give us the proper yield.(Consult with your chemical supplier for their recommendations.) Remember, we are looking for clues as to why we are lacking one chemical or the other at the gun outlet.
If we have determined the “A” (ISO) side to be lacking at the gun, then we need to check the gauge backpressure readings. When the “A” side is higher than the “B” side, this indicates a restriction on the “A” side anywhere from the gun mix chamber back to the fluid outlet manifold. In other words, we are holding our thumb over the “A” side outlet. These restrictions can include blockage in the mix chamber, gun screen, whip hose, hose temperature sensor or main fluid line. Other causes easily overlooked could include the possibility of the “A” side chemical being thicker than the “B” side which is often due to cold material, heater problems or the “B” side port having been increased by wear. In this case, we are reducing the “B” side backpressure while causing a resin-rich, or too much “B” condition.
If we stick to the same “A” example, but we find the “A” side fluid gauge to be lower than the “B” side, this indicates a problem from the fluid outlet gauge back to the drum feed supply. This results in starving the supply with one of the following scenarios: supply feed pump malfunction, restriction of the feed hose or filter strainer, drum not properly being vented due to bung in place, desiccant breather clogged, debris in the bottom of the drum container, dented drum bottom restricting the feed pump inlet, “A” side proportioner pump has debris, or a stuck ball in the inlet or discharge ball check seat area. Again, one problem area that is often overlooked when circulating material back to the drum is that the control valve could be leaking, or diverting pressure and material back to the drum.
The previous example focuses on the "A" side. However, if you have determined that the "B" side (Resin) is the cause of the pressure imbalance, apply the same tests to the "B" side.
So let’s save the “shotgun” for bird hunting, and save time and money for our business by paying attention to what our gun and gauges are telling us.
If you have any topic matters that you would be interested in hearing about, then please send them in through our Product Knowledge Exchange (PKE). You can find many answers to frequently asked questions there, or you can “Ask a Question” which will be answered by one of our product experts by the next business day. This is a great location to find information on all our products, whether in North America, or anywhere in the world with Internet access.

Engineering Spotlight
by Mark Weinberger, Engineering Manager
At Graco, we feel that the Graco Fusion® CS Gun has unprecedented features, which will change the way your customers spray. In addition to the improved quality, the Fusion CS gun provides economic benefits by maximizing daily spraying uptime as well as reducing time and money on material.
Contractors confirm the Clear Shot™ Liquid maintains a clean pattern throughout the day, maximizing foam yield and productivity with minimal training.
The variable flow device is another feature appreciated by contractors. Graco recommends setting up with a 02 mix chamber, adjusting the variable flow to about half-flow, giving you the performance of an 01 mix chamber. It’s like getting a 01 mix chamber for free! Other sprayers have found reducing the flow to near minimum setting creates a streaming pattern, perfect for spraying hard to reach areas.
Other elements like the short trigger pull reducing operator fatigue, hose manifold with ball valves for tool-less operation, ChromeX coated mix chambers and sides seals for maximum life, less purge-air reducing foam blowback and light weight make the Fusion CS gun the best gun available.

Fusion CS Gun Tips for Improved Performance
Less Drilling. More Spraying.
The Graco® Fusion CS gun is different from any gun you’ve sprayed before. Since it uses ClearShot™ Liquid to keep the mix chamber clean, you may need to modify some of your spraying and maintenance techniques to achieve the best results.
While working with our many end-users, Graco developed some tips for best practice spraying. We quickly realized that the Fusion CS gun was not being maintained properly. The Fusion CS gun is not designed the same as the Fusion AP gun. In order for the Fusion CS gun to operate as intended, different spraying and maintenance techniques are required.
For a better understanding of your new Fusion CS gun, take a moment to download and review the following spraying tips by clicking on this link. The guide, entitled “Getting the Best Results from your Fusion CS Spray Gun,” details how to resolve the most commonly encountered issues.
Graco also created a product page for the Fusion CS gun as well as provided other information like helpful hints and FAQ’s online at the Product Knowledge Exchange (PKE). To use Graco’s PKE, visit http://www.graco.com/, choose Tech Support and click on “Go to PKE.” Search with keywords “Fusion CS.”

How much power is enough?
By Barry Taft, Graco Technical Assistance
One question we get in our technical assistance group on a regular basis is, “How much power is required to operate our foam or polyurea proportioner?” There are many things to consider when planning for a generator or shore power supply.
This article is not intended to replace the expertise of a certified electrician. Please consult a certified electrician before purchasing or installing any generator. In addition, Graco has recently added guidelines and tips on choosing and setting up a generator in all proportioner manuals which can be downloaded from www.graco.com. Refer to manuals 312065 and 312062.
Generator under-sizing is all too common due to budget concerns, lack of understanding and misinformation. This mistake is not only jeopardizing the generator, but all equipment that is being powered by it. I can honestly say that no one has ever contacted me to let me know that too large a capacity generator has given the owner concern. I can share many stories where too small a power supply has damaged equipment – leading to costly repair and down time. That said, too much kilowatt capacity is better than not enough.
Before inquiring about a generator purchase, you need to calculate your power requirements. Make a list of all the items that you intend to incorporate into your trailer before you start your shop comparison. The total system requirements for Graco proportioners are listed in the operation manual under the model's description and/or in the technical data sections. In addition to the proportioner, consider the other electrical equipment requirements in a trailer operation. This can include air compressor, air dryer, fresh air panel, lights, various outlets for electrical agitators, power tools, etc. Heat and air conditioning is often overlooked. It is not for the operators, but for the materials. Chemicals with 245fa blowing agent must be stored below 90°F (32°C) to keep from off-gassing.
Generator sizing
• List system components using starting requirements, in watts
• Add-up watts required
• Multiply total watts by 1.25 = KVA (Kilovolt-ampere), use this number to size the generator
Proper system set up, start up and shut down procedures are critical to the operating equipment and generator. The order of the steps are important, follow them closely. Failure to do so will cause voltage fluctuations that can, over time, damage electronic equipment.
Start up
• Check fluid levels on generator (oil, coolant and fuel). Running out of fuel can cause severe damage to the generator and powered equipment. A 40 – 60 kW generator working at ¾ load can consume approximately 3 – 4 gallons per hour. Verify that there is enough fuel to complete each day's task.
• Ensure that the Reactor disconnect switch is in the off position
• Ensure main breaker on the generator is in the off position
• Check the oil in the air compressor
• Close the bleed valve on the compressor
• Start the generator and allow it to come to full operating temperature, at least five minutes
• Turn on the main breaker for the generator
• Engage the compressor starter and air dryer if included
• Turn on power to spray machine – refer to the equipment manual for proper operation
While running
• Use air compressors with constant speed head unloading. Direct in-line air compressor starting and stopping will draw high currents, as high as 9 times the full current load, causing massive voltage fluctuations across the system, damaging equipment.
Shut down
• Relieve spray machine system pressure and park the machine in accordance to the equipment operations manual
• Turn off power to the spray machine
• Turn off air compressor and dryer
• Open compressor bleed valve to relieve pressure and remove water from tank
• Turn off main breaker on generator
• Allow generator dwell time before shutting down per manufacturer's recommendations
• Plug into shore power if engine block heater and or trailer heater is required in colder weather

Spray Polyurethane Foam Insulation Safety
.jpg)
The Center for the Polyurethanes Industry (CPI) and the Spray Polyurethane Foam Alliance (SPFA), along with industry participants from OSHA, NISOH and CPSC, have undertaken a major initiative to help educate the supply chain on the safe use and handling of of spray polyurethane foam insulation (SPFI). “As spray polyurethane foam insulation becomes increasingly important in helping this country meet its aggressive energy efficiency goals, it’s become even more critical for the industry to provide timely, easy to understand product stewardship information,” says Neeva-Gayle Candelori, director of CPI. “The website www.spraypolyurethane.com contains downloadable information in user-friendly documents. We’ll keep posting new information to the site as this program grows, and we encourage you to visit the site often for updates.”
Proper Whip Hose Usage
For best results, be sure to attach the whip hose to your gun in a helix configuration as shown. Proper installation has been shown to improve hose flexibility by up to 60 percent. More hose flexibility means:
• Easier to maneuver the gun
• Greater range of spraying motion
• Easier to reach tight areas and
spray at odd angles
• Less operator fatigue
Assembly procedure:
Tighten fittings to A and B component hoses. Ensure the hose remains flat after fittings are tightened. Loosen and retighten fittings as necessary to eliminate any torque on the hoses. This will help achieve a flat profile on the hose assembly. Refer to instruction manual 309572 for more information.

It is estimated that 20,000 tons of polyurea will be applied to the platform throughout the duration of the project, making the Beijing-Shanghai High-Speed Railway currently one of the world's largest polyurea waterproofing projects.Construction crews are using Graco Reactor® Plural-Component Proportioners to apply the polyurea and Graco Xtreme® Airless Sprayers to apply a basecoat underneath the polyurea. The Beijing-Shanghai High-Speed Railway project is expected to be finished by 2011 and an estimated 220,000 passengers will use the expressway each day.
