Pressure Relief

SKIN INJECTION HAZARD

High-pressure fluid from dispense device, hose leaks,
or ruptured components will pierce skin. This may look
like just a cut, but it is a serious injury that can result in
amputation. Get immediate surgical treatment.

Follow Pressure Relief Procedure in this manual,
when you stop dispensing and before cleaning, check­ing, or servicing equipment.

Relieve pressure in system by using two wrenches
working in opposite directions on pump element and
pump element fitting to only loosen fitting.

NOTE: When loosening pump element fitting, do NOT
loosen pump element. Loosening pump element will
change the output volume.

1. Disconnect power source.

2. Relieve pressure following Pressure Relief Proce­dure provided.

3. Disconnect anything installed to pump element such
as pressure relief valves, output union, or other fit­tings.

4. Use a wrench to loosen pump element (1) and com­pletely remove pump element and spacers (2) from
G3 housing.

Make sure spring (a), retainer (b) and piston (c) are
removed with pump element (F
