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 ampu-
tation. 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.
