NOTE: The terms ISO and RES used in the text refer to

the polyurethane foam chemicals, Isocyanate and Resin.

NOTE: Reference numbers and letters in parentheses in the text refer to the figure illustrations and the Parts Drawing.

WARNING

A bleed–type master air valve (E) is required in your system, to help reduce the risk of serious injury, including splashing fluid 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 (E) relieves air trapped between this valve and the pump after the pump is shut off. Trapped air can cause the pump to cycle unexpectedly and result in serious injury, including amputation. Locate the valve close to the pump.

Installing the Feed Pumps

1. Screw the bung adapter (40) and pump tightly into the drum cover. See Fig 1.

2. Tighten the retainer (38) firmly to complete the airtight seal.

3. Separate the two halves of the identification label (15) along the perforation. Clean the surface of the air motor with solvent and apply the appropriate label (RES or ISO) to identify the type of material being pumped.

4. Install an air regulator in the feed pump air inlet to control pump speed. To install, remove the air valve (8) and use suitable adapters for the regulator and pin fitting. Use thread sealer on male threads.

5. Connect an air supply hose to the 1/4 npt air line coupler (13). Air supply hoses (103) are supplied in Kit 217381. See Fig 3, page 6.

6. Connect a fluid supply hose from the 3/4 npt(f) fluid outlet of the ISO feed pump to the inlet fitting of the ISO proportioning pump, using adapters as needed. Then connect a fluid supply hose between the RES feed pump and RES proportioning pump.

CAUTION

Be sure all hose connections in your polyurethane foam spray system are clearly labeled ISO or RES and make connections only with identically labeled components to avoid material crossing.

Crossing polyurethane materials will cause the material to harden in the equipment and may permanently damage it.

Grounding

Remove the ground screw (Z) and insert through eye of ring terminal at the end of ground wire (Y). Fasten ground screw back onto pump and tighten securely. See Fig 2. Connect the other end of the wire to a true earth ground. Order Part No. 222011 Ground Wire and Clamp.

Feed Pump Kit Installation

The following instructions assume you are using this kit with a Graco Foam–Cat Sprayer.

WARNING

Static electricity is created by the high velocity flow of fluid through the pump and hoses. If every part of the spray system, and all objects in the spray area are not properly grounded, the static electricity may cause sparking. Sparks can ignite fumes from solvents and the fluid being sprayed, dust particles, and other flammable substances, causing a fire, explosion and serious bodily injury and property damage.

To reduce the risk of static sparking, use only conductive air and fluid hoses and be sure your entire system is properly grounded. Ground the feed pumps as explained below.

1. Install the feed pumps as described in Steps 1–4, on page 4.

2. Mount the Air Dryer (105) in any suitable location. Refer to manual 307548 for the mounting hole diagram. See Fig 3.

3. Unscrew the air dryer ring (F) to remove the bowl. See Fig 3. Remove the filter and fill the bowl with the desiccant, provided. Reassemble.

CAUTION

One end of each fluid hose and each drum nipple (G) of the drum fittings (H) is labeled ISO or RES. Make only ISO to ISO and RES to RES connections to avoid material crossing.

4. Install the drum fittings (H) in the 3/4 in. vent port of the proper drum.

5. Connect the dry air hoses (M) to the identically labeled drum fittings using the special pin fitting (J) and coupler (N). See Fig 3.

The special air line fitting (J) and coupler (N) are designed to prevent accidentally coupling an unregulated air supply hose to the container. Unregulated air can overpressurize the container and cause it to rupture, resulting in serious bodily injury and property damage. If the coupler and fitting ever needs to be replaced use only original Graco parts.

Never substitute a different type of coupler and fitting!

WARNING

Operation

Pressure Relief Procedure

WARNING

PRESSURIZED EQUIPMENT HAZARD

The system pressure must be manually relieved to prevent the system from starting or spraying accidentally. To reduce the risk of an injury from accidental spray from the gun, splashing fluid, or moving parts, follow the Pressure Relief Procedure whenever you:

• are instructed to relieve the pressure,

• have an air supply interruption,

• stop spraying,

• check or service any of the system equipment,

• or install or clean the spray nozzle.

Starting and Operating the Pump

This pump is designed to be used with a Graco Foam-Cat Sprayer. If you have purchased such a sprayer, complete warning and operating instructions are contained in the manual (307541 or 307542) which accompanied the sprayer. If you have misplaced these manuals, obtain additional copies by contacting your Graco distributor.

Changing Drums

CAUTION

To avoid crossing material when changing drums, complete the changing of one type of material before starting the other.

1. Disconnect the hose coupler (N) from the Air Dryer drum fittings (H). See Fig 3.

2. Leave the ball valve (K) open for a few minutes to release the air pressure in the drum, then close the valves.

3. Remove the pump and the drum fittings from the drum cover and install them in the new drum of material.

4. Repeat this procedure for the other material.

In general operation, when the pump is used for transfer and supply operations with no dispensing valve, the pump will run whenever air is supplied.

Normally, the Feed Pump air valve is opened before any other equipment in the spray system is turned on. This is so fluid can be supplied to the components immediately. For shutdown, disconnect the air line coupler (13). See Fig

4.

Never let the pump run when the drum is empty. A dry pump can quickly accelerate to a high speed and damage itself. If the pump is running too fast, stop it immediately and check and refill the material supply, or flush the pump with a compatible solvent if you stop spraying for the day. Always prime the entire system with fluid to remove any air pumped into the system. Refer to Manual 307541 or

307542. Don’t let the material harden in the pump.

Feed Pump Kit

Refer to the operation instructions on page 2 of manual 307548, which was supplied with the Air Dryer, and the above instructions for operating the Feed Pumps.

Bung Adapter

If the ISO material shows signs of crystallization, and whenever the pump is removed from the drum, check the oring (39) and gasket (41) for wear or damage, replacing as needed. Refer to the Parts Drawing.

ISO Pump Packing Protection and Lubrication

CAUTION

Use only IPL (Isocyanate Pump Lube) to lubricate the packings of the feed pump. Other types of lubricant are not as effective in preventing packing damage.

1. Insert the 14.6 oz. cartridge (16) of IPL in a standard grease gun.

2. At shutdown each day, stop the pump with the rod (34) in the down position, then lubricate the packings liberally with IPL through the grease fitting (36). Proper lubrication prevents pump sticking. See Fig 4.

3. Wipe off the extra, contaminated IPL from around the top of the packing nut (28) and displacement rod (34).

4. Coat the displacement rod with fresh IPL.

Air Lubrication

If the air supply is dry, periodically oil the air motor. For manual lubrication, turn off the air, put about 15 drops of lightweight motor oil in the air inlet (7), reconnect the hose, and turn on the air. See Fig 4.

1. Open the air valve (8) or regulator to start the pump. Allow the pump to cycle slowly for at least 5 minutes.

Flushing

CAUTION

Be sure the solvent used is compatible with the material to be pumped to avoid material contamination.

1. Connect a short hose to the pump outlet.

2. Insert the pump intake into a pail of solvent.

3. Direct the fluid hose into the pail.

2. Stop and disconnect the air hose.

3. Be sure to relieve the fluid pressure.

4. Push up on the intake valve (35) check plate to drain the lower part of the pump. See Fig 5.

5. Turn the pump over to drain the upper part of the pump.

Adjusting the Packing Nut

WARNING

Follow the Pressure Relief Procedure on page 7 before adjusting the packing nut.

Periodically, check the tightness of the packing nut (28). It should be tight enough to prevent leakage; no tighter. See Fig. 4. If the leakage cannot be stopped, change the packings to prevent exposure to the fluid being pumped.
