Operation

Pressure Relief Procedure

Follow the Pressure Relief Procedure whenever
you see this symbol.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as splashing fluid and moving
parts, follow the Pressure Relief Procedure when you
stop dispensing and before cleaning, checking, or
servicing the equipment.
1. Turn off and disconnect the power supply.
2. Trigger the dispense valve into a grounded waste
container to relieve pressure.

Duty Cycle

The pump is designed to operate for a 50% duty cycle.
It can operate up to a maximum of 30 minutes of run
time, with an equal amount of down time.
NOTICE
Never allow the pump to operate dry. Make sure that
the pump has fluid in it when the pump is initially
installed. Do not run the pump for more than five (5)
minutes with the pump discharge blocked. Do not
operate the pump continuously more than 30 minutes
in one (1) hour. Failure to follow these instructions can
result in damage to the pump.

Thermal Overload

The motor has a thermal overload switch that shuts the
motor down when overheated. If the unit overheats,
allow approximately 45 minutes for the unit to cool.
Once the unit has cooled down, the switch will close
and the unit will restart.
To reduce risk of injury from motor starting
unexpectedly when it cools, always turn the power
switch to OFF if the motor shuts down.

Pump Start Up

1. Check that the ball valve is in the OFF position.
2. Turn the power switch, located on the back of the
motor, to the ON position to start the pump.
NOTE: The pump has an internal bypass valve
(Pressure Relief Valve) that opens when the pump
discharge pressure exceeds 65 psi. If the flow is
blocked, the fluid will bypass within the pump.
3. Insert the nozzle (15) into the container and open
the ball valve (16) to dispense fluid.
4. Turn the switch to the OFF position immediately
after finishing dispensing.
5. Close the ball valve (16).
