WARNING

PRESSURIZED EQUIPMENT HAZARD

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

DAre instructed to relieve pressure

DCheck, clean, or service any system equipment D Install or clean fluid nozzles or filter

Pressure Relief Procedure

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.

WARNING

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.

Installation Procedure

CAUTION

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.

1. If this is an existing installation, go to step 7.

Steps 2 through 6 are the Flushing Procedure.

2.Close the fluid shut-off valve (J) at each dispense position.

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.

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.

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.

6.Repeat step 5 at all other dispense positions.

7.Relieve the pressure.

Pre-Installation Procedure

1.Relieve the pressure.

WARNING

To reduce the risk of serious injury whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure above.

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.

WARNING

To reduce the risk of serious injury, whenever you are instructed to relieve pressure, always follow the Pressure Relief Procedure at left.

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.

NOTE: Make sure you let the sealant cure to the manufacturer’s recommendations before you let fluid into the system.
