1.

Turn off the power supply to the pump.

2.

Trigger the dispense valve into a waste container to 
relieve pressure.

3.

Open any bleed-type master air valves and fluid 
drain valves in the system.

4.

Leave the drain valve open until you are ready to 
pressurize the system

NOTE:

 

If you suspect the dispensing valve, extension or 

grease fitting coupler is clogged, or that pressure has 
not been fully relieved after following all the previous 
steps,

 using a rag VERY SLOWLY loosen the coupler or 

hose end coupling and allow pressure to be relieved 
gradually, then loosen the part completely. Now clear the 
clog.

Installation Procedure

If this is an existing installation, go to step 6.

1.

Close the fluid shut-off valve (A) at each dispense 
station. See Fig. 1, page 4.

2.

Make sure the main fluid outlet valve at the pump is 
closed, the air pressure to the pump motor is 
adjusted, and the air valve is open. Slowly open the 
main fluid valve.

3.

Place the hose end (with no dispense valve con-
nected) into a container for waste grease. Secure 
the hose in the container so it will not come out dur-
ing flushing. If you have multiple dispense positions, 
first flush the dispense position farthest from the 
pump, and work your way toward the pump.

4.

Slowly open the shut-off valve (A) at the dispense 
station. Flush out a sufficient amount of grease to 
ensure that the entire system is clean, and close the 
valve.

5.

Repeat step 4 at all other dispense stations.

6.

Relieve the pressure

WARNING

If high-pressure fluid pierces the skin, the injury might 
look like “just a cut” but is a serious wound. Get imme-
diate medical attention

Always shut off power and relieve pressure before 
you service or clean fluid dispenser, remove 
parts, or repair leaks. See 

Pressure Relief Pro-

cedure

.

Keep clear of tip, and never point dispenser at 
yourself or anyone else.

WARNING

Fire and Explosion Hazard

The movement of fluids through the dis-
pensing system generates static electricity. 
The static electricity can cause volatile 
fumes to ignite, resulting in explosion and 
fire. The dispensing system must be 
grounded. See Grounding on page 6.

CAUTION

If this is a new installation, or if the grease in the 
lines is contaminated, flush the lines before you 
install the metered valve. Contaminated lines can 
cause the valve to leak or malfunction.

WARNING

Pressurized Equipment Hazard

To reduce the risk of serious injury, when-
ever you are instructed to relieve pressure, 
always follow the Pressure Relief Proce-
dure on page 4.
