Priming
1. Attach a priming hose to the outlet of the pump.
Insert the opposite end of the hose into the tank
through the fill opening.
2. Turn the power switch ON. The pump should prime
in a few seconds.
NOTE: If priming does not start:
Remove the priming plug (21) from the pump
housing.
Using an oil can, fill the pump with 8 oz. (0.24 L) of
oil.
Replace the priming plug (21).
Turn the power switch ON. The pump should prime
in a few seconds.
Once the pump is primed, the inlet check valve will
prevent loss of prime.
3. When the pump starts to prime, turn the power
switch OFF.
4. Disconnect the priming hose.
5. Attach system plumbing to the pump outlet.
Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
1. Turn off and disconnect the power supply to the
pump.
2. Open the dispense valve into a grounded waste
container to relieve pressure.
3. Close the dispense valve.
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.
Duty Cycle
The pump is designed to operate at a 40% duty cycle.
It can operate up to a maximum of 20 minutes of run
time, with 30 minutes of down time.

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.
To reduce risk of injury from motor starting
unexpectedly when it cools, always turn the power
switch to OFF if the motor shuts down.
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.
