Operation
Pressure Relief Procedure
WARNING
PRESSURIZED EQUIPMENT HAZARD
The system pressure must be manually relieved to prevent the system from starting or spraying acci- dentally. To reduce the risk of an injury from acci- dental spray from the gun, splashing fluid, or mov- ing parts, follow the Pressure Relief Procedure whenever you:
Dare instructed to relieve the pressure,
Dstop spraying,
Dcheck or service any of the system equipment,
Dor install or clean the spray tips.
1.Shut off the air to the pump.
2.Trigger the spray gun.
3.Open the fluid drain valve to relieve all fluid pres- sure, having a container ready to catch the drain- age.
Flush the Pump Before First Use
The pump was tested in water. If the test solution could contaminate the fluid you are pumping, flush the pump thoroughly with a compatible solvent. Follow the procedure in Starting and Adjusting the Pump.

WARNING
TOXIC FLUID HAZARD
Hazardous fluid or toxic fumes can cause serious injury or death if splashed in the eyes or on the skin, inhaled, or
swallowed. Do not lift a pump under pressure. If dropped, the fluid section may rupture. Always fol- low the Pressure Relief Procedure above before lifting the pump.
1.Be sure the pump is properly grounded. Read FIRE OR EXPLOSION HAZARD on page 3.
2.Check all fittings to be sure they are tight. Be sure to use a compatible liquid thread sealant orPTFEr tape on all male threads. Tighten the fluid inlet and outlet fittings snugly. Do not overtighten the fittings into the pump.
3.On pail mount units, place the suction tube in a pail of fluid and attach the pail cover using the thumbscrews. Tighten securely.
On wall mount units, install the suction tube and bung plug in the fluid supply drum as explained on page 5.
4.Make sure the air regulators (G and H) and bleed valves (B and E) are closed. Open the fluid drain valve (J).
5.Connect the air line coupler (D) to the air inlet fit- ting.
6.With the gun air regulator (G) closed, open the
7.Allow the pump to cycle slowly until all air is pushed out of the recirculation line and the pump is primed.
8.Point the spray gun (R) into a grounded metal pail, holding a metal part of the gun firmly to the side of the pail.
9.Trigger the air spray gun. Open the gun air regula- tor (G) and close the fluid drain valve (J). Allow the pump to cycle slowly until all air is pushed out of the fluid hose and gun.
If you are flushing, run the pump long enough to thoroughly clean the pump and hoses. Close the air regulator. Remove the suction tube from the solvent and place it in the fluid to be pumped.
