Installation Procedure  
WARNING  
PRESSURIZED EQUIPMENT HAZARD  
CAUTION  
The equipment stays pressurized until pressure is  
manually relieved. To reduce the risk of serious  
injury from pressurized fluid, accidental spray from  
the dispense valve, or splashing fluid, follow the  
Pressure Relief Procedure when you  
If this is a new installation, or if the fluid in the  
lines is contaminated, flush the lines before you  
install the metered valve. Contaminated lines  
could cause the valve to leak.  
D Are instructed to relieve pressure  
D Check, clean, or service any system equipment  
D Install or clean fluid nozzles or filter  
1. If this is an existing installation, go to step 7.  
Steps 2 through 6 are the Flushing Procedure.  
Pressure Relief Procedure  
2. Close the fluid shut-off valve (J) at each dispense  
position.  
1. Turn off the power supply to the pump.  
3. 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.  
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. Place the hose end (with no dispense valve con-  
nected) into a container for waste oil. Secure the  
hose in the container so it will not come out during  
flushing. If you have multiple dispense positions,  
first flush the dispense position farthest from the  
pump, and work your way toward the pump.  
4. Leave the drain valve open until you are ready to  
pressurize the system.  
WARNING  
5. Slowly open the shut-off valve (J) at the dispense  
position. Flush out a sufficient amount of oil to  
ensure that the entire system is clean, and close  
the valve.  
FIRE AND EXPLOSION HAZARD  
The movement of fluids through the  
dispensing system generates static  
electricity. The static electricity can  
cause volatile fumes to ignite, resulting in explosion  
and fire. The dispensing system must grounded.  
See Grounding on page 6.  
6. Repeat step 5 at all other dispense positions.  
7. Relieve the pressure.  
Pre-Installation Procedure  
WARNING  
To reduce the risk of serious injury, whenever you  
are instructed to relieve pressure, always follow the  
Pressure Relief Procedure at left.

To reduce the risk of serious injury whenever you  
are instructed to relieve pressure, always follow the  
Pressure Relief Procedure above.  
8. Slide the swivel cover (4) of the PM5 onto the  
hose, small end first. See Fig. 3.  
9. Apply thread sealant to the male threads of the  
hose fitting, thread the hose fitting into the swivel  
(3) of the PM5, and tighten it firmly. See Fig. 3.  
2. Close the shut-off valve (item J in Fig. 1).  
3. Ground the hose and reel or console. See  
Grounding on page 6. Leave a minimum two  
engaged threads bare when using PTFE tape. The  
bare threads ensure a ground is maintained.  
NOTE: Make sure you let the sealant cure to the  
manufacturer’s recommendations before you let  
fluid into the system.
