Graco P39LCS Manual De Usuario

 

Be sure all air lines (T) and fluid lines (S) are properly 

sized and pressure-rated for your system. Use only 

electrically conductive hoses. Fluid hoses must have 

spring guards on both ends.

Mounting Accessories
Mount the pump package to suit the type of installation 

Refer to Check-Mate Displacement Pump manual 

312375 for mounting hole layout.

Air Line Accessories
Install the following accessories as listed. Refer to F

to see air line accessories represented in a typical sup-

ply unit installation. 

•

Main air shutoff valve (W) isolates the air line 

accessories for servicing. Locate upstream from all 

other air line accessories. 

•

Air line filter (V) removes harmful dirt and moisture 

from the compressed air supply. Also, install a drain 

valve at the bottom of each air line drop, to drain off 

moisture.

•

Air regulator (G and AH) 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.

•

Air motor valve (AJ) is required in your system to 

shut off the air supply to the pump (see WARNING). 

When closed, the valve will bleed off all air in the 

pump. Be sure the valve is easily accessible from 

the pump. 

•

Pump runaway valve (AK) 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. Locate in the position shown.

•

Pump bleed valve (P) is required in your system to 

relieve fluid pressure in hose and gun (see WARN-

ING). 

Fluid Line Accessories
Install the following accessories as listed. Refer to F

to see fluid line accessories represented in a typical 

supply unit installation. 

•

Install a fluid shutoff valve at each gun/valve drop, 

to isolate the gun/valve and fluid accessories for 

servicing.

•

Install a fluid drain valve near the pump fluid outlet, 

and at each gun/valve station. The drain valves are 

required in your system to relieve fluid pressure in 

the displacement pump, hose and gun/valve (see 

WARNING). Drain valves at the gun/valve stations 

may be mounted in the base of a fluid regulator, 

using an adapter.

•

Fluid regulator controls fluid pressure to the 

gun/valve, and dampens pressure surges.

•

Gun or dispense valve dispenses the fluid.

•

Gun/valve swivel allows freer gun/valve movement.

A main air bleed valve and pump bleed valve (P) are 

required. These accessories help reduce the risk of 

serious injury, including fluid injection and splashing of 

fluid in the eyes or on the skin, and injury from moving 

parts if you are adjusting or repairing the pump.

The main air shutoff valve shuts off the air to the pump 

and ram. The air motor valve relieves air trapped 

between this valve and the pump after the air is shut 

off. Trapped air can cause the pump to cycle unexpect-

edly. Locate the valve close to the pump. 

The pump bleed valve assists in relieving fluid pressure 

in the displacement pump, hose, and gun/valve. Trig-

gering the gun/valve to relieve pressure may not be 

sufficient.

If using Check-Mate pump with Graco Supply Sys-

tems, refer to Supply Systems Operation manual 

for system accessory installation instructions.
