Installation

General Information

NOTE: Reference numbers and letters in parentheses in the text refer to the callouts in the figures and the parts drawings.

NOTE: If you supply your own accessories, be sure they are adequately sized and pressure–rated to meet the system’s requirements.

Fig. 2 is only a guide for selecting and installing sys- tem components and accessories. Contact your Graco distributor for assistance in designing a system to suit your particular needs.

System Accessories

WARNING

Two accessories are required in your system: a bleed–type master air valve (J) and a fluid drain valve (N). These accessories help reduce the risk of serious bodily injury including fluid injection, splashing in the eyes or on the skin, and injury from moving parts if you are adjusting or repairing the pump.

The bleed–type master air valve relieves air trapped between this valve and the pump after the air is shut off. Trapped air can cause the pump to cycle unexpectedly. Locate the valve close to the pump.

The fluid drain valve assists in relieving fluid pres- sure in the displacement pump, hose, and gun. Triggering the gun to relieve pressure may not be sufficient.

Air and Fluid Hoses

Be sure all air and fluid hoses are properly sized and pressure-rated for your system. Use only grounded air and fluid hoses. Fluid hoses must have a braided stainless steel cover (or have spring guards on both ends).

Mounting Accessories

Mount the pump (A) to suit the type of installation planned. The pump dimensions and mounting hole layouts are shown on pages 28 and 29.

The Typical Installation on page 7 shows the pump

(A)mounted on a pneumatic elevator cart (B). The pump may also be mounted on a 19 liter (5 gal.) pail ram. In either case, it is used with a wiper plate (C). Refer to the separate manuals for the cart, ram, and wiper plate for further information.

Kits 223881 and 224829 are available to mount the pump on a 200 liter (55 gallon) ram. Refer to the separate manuals included with the kits for further information.

Air Line Accessories

Install the following accessories as shown in Fig. 2, using adapters as necessary:

DA pump runaway valve (G) senses when the pump is running too fast and automatically shuts off the air to the motor. A pump which runs too fast can be seriously damaged. Install closest to the pump air inlet.

DAn air line lubricator (H) provides automatic air motor lubrication.

DA bleed-type master air valve (J) is required in your system to relieve air trapped between it and the air motor when the valve is closed (see the WARNING at left). Be sure the bleed valve is easily accessible from the pump, and is located down- stream from the air regulator.

DAn air regulator (K) controls pump speed and outlet pressure by adjusting the air pressure to the pump. Locate the regulator close to the pump, but upstream from the bleed-type master air valve.

DAn air line filter (L) removes harmful dirt and moisture from the compressed air supply.

DA second bleed-type air valve (M) isolates the air line accessories for servicing. Locate upstream from all other air line accessories.

DAn air line quick disconnect coupler (F) is required for pumps mounted on the pneumatic elevator cart. The female coupler attaches to the end of the air hose (D), and the male coupler screws into the air manifold (E). See the separate cart manual for further information.

The unit boasts a powerful motor that supports high-pressure spraying, ideal for large surface areas and demanding projects. Additionally, the ergonomic design ensures ease of use, allowing operators to navigate tight spaces effectively.

Another significant advantage of the 222839 Series A is its compatibility with a wide range of coatings, including stains, sealers, and paints. The sprayer’s adjustable flow rate and pressure settings give users precise control over the application, ensuring a flawless finish without overspray. The integrated filter system reduces the risk of clogs, enabling uninterrupted work even with thicker materials. Furthermore, safety features such as an automatic shut-off mechanism enhance user protection during operation.

On the other hand, the Graco 222907 Series A is particularly suited for professional painters and contractors who require high efficiency and reliability in their tools. This model shares similarities with the 222839 in terms of build quality but offers several distinctions. It includes the SmartControl technology, which provides consistent pressure output for a superior finish, regardless of the viscosity of the material used.

The 222907 Series A also features ProConnect, which allows for quick and easy setup and breakdown, making it ideal for on-the-go applications. Its transport design, including a robust cart with large wheels, further facilitates maneuverability across various job sites. Additionally, the easy-to-read pressure gauge helps operators monitor performance, ensuring the best possible outcomes for their projects.

In conclusion, both the Graco 222839 Series A and the 222907 Series A deliver exceptional performance with innovative technologies aimed at improving efficiency and user experience.
