OPERATING CONDITIONS
1. ENVIRONMENTAL CONDITIONS
Temperature: Min -4°F (-20°C)/ Max +140°F (+60°C)
Relative Humidity: Max 90%
2. FLUID COMPATIBILITY
These products are compatible with the following fluids: Diesel, Kerosene and/or Mineral Spirits.
DO NOT use with other fluids.
INSTALLATION
1. Tightly screw suction pipe into inlet coupling of pumping unit. Extend suction pipe into truck tank or barrel.
Make sure that there is at least 3in. away from tank bottom.
2. Screw inlet coupling of pump into 2in. tank or barrel opening. Inlet coupling must be completely and
securely threaded into an undamaged tank or barrel bung.
3. During installation and maintenance, make sure that the electric supply lines are not live.
4. Always turn off the switch before supplying electrical power.
5. Check the correct rotation direction of the DC pump. If it is inverted, check the polarity of the connection
cable.
a) RED cable: positive pole (+)
b) BLACK cable: negative pole (-)
6. Systems should be designed to require a minimum amount of suction lift. Maximum “equivalent feet of lift”
is 8ft. for diesel fuel. (Equivalent feet of lift is the vertical distance from the bottom of the suction pipe to
the inlet of the pump, plus the friction losses through the vertical and horizontal runs of pipe, elbows and
other fittings.)
7. Tank or barrel must be properly vented. A water separator should be used for pumping diesel fuel.
8. Power to the unit should be supplied from a dedicated 30 Amp circuit breaker. No other equipment should
be powered from this breaker. If two pumps are supplied from one breaker, that breaker must be capable
of handing the load of both motors.
NOTE: Use oil resistant pipe sealant or Teflon® Tape on all pipe threads.
DAILY USE
If using flexible tubing, attach the ends of the tubing to the tanks. In the absence of an appropriate slot,
solidly grasp the delivery tube before beginning dispensing.
Before starting the pump, make sure that the delivery valve is closed (dispensing nozzle or line valve).
Turn the ON/OFF switch to ON. The bypass valve allows functioning with the delivery closed for only brief
periods (max. 2 minutes).
Open the delivery valve, solidly grasping the end of the tubing.
Close the delivery valve to stop dispensing.
When dispensing is finished, turn off the pump.
CALIBRATION OF FLOW METER
The meter used in the pumping unit is pre-calibrated in factory. Calibration is recommended upon initial use,
after disassembly or significant wear. Please check the calibration of the meter as follows.
