DEPRESSURISATION
WARNING
Pumps or dispensers must first be depressurized before carrying out any hydraulic
work on them.
When carrying out this operation:
y Wear safety glasses and other appropriate safety gear.
y Isolate the dispenser from the feed line.
y With the nozzle triggers fully open and the nozzles placed in a container to
capture any product, use the “Stack Test” to open the valves manually.
y In the case of a Bennett Pump, any remaining residual
pressure can be released by removing the pressure relief
plug (arrowed). Cover with a rag to capture any potential
spray. Fluid will drain from here so replace the plug or
capture.
y Isolate the pump or dispenser from its power supply.
y Care must be taken when disassembling the hydraulics as pressure may still
be present. We recommend, when breaking any joint or connection, to do so
slowly and cover with a rag to capture any spray. Be prepared with a container
to capture spilled product.
