Macnaught Ahfp12a 12v Wall Mount Diesel Pump Kit Instruction Manual

• Insert the suction hose into the fuel tank. Ensure the tank or
  barrel is anchored to prevent tipping.
• Connect the alligator clips on the power cord to a battery
  capable of delivering the necessary voltage and current. Attach the
  red clip to the positive (+) battery terminal and the black clip to
  the negative (-) battery terminal or vehicle frame.

• Before use, clean any dirt or moisture from the nozzle or
  hoses.
• Insert the nozzle into the container to be filled and insert
  the suction hose into the diesel storage tank if applicable.
• Avoid using a patch cord to extend the power cables to prevent
  sparks that could cause a fire.
• The meter displays both batch total and accumulative totals
  when fluid passes through it.
• To reset the batch total to zero, rotate the reset knob on the
  meter.
• Do not let the pump run dry or run in bypass mode for more than
  2 minutes to prevent damage.

Please refer to the complete instruction manual provided with

2. Fit the Pump unit securely to the desired location.
3. Connect the delivery hose to the outlet on the meter body.
4. Connect the remaining end of the delivery hose to the automatic nozzle

PUMP INSTALLATION

INSTRUCTION MANUAL

OPERATION
NOTE: Avoid sparks that could cause a fire: DO NOT use a patch cord to extend the power cables.

METER OPERATION
Both the batch total and accumulative totals turn simultaneously when fluid passes through the meter.
To reset the batch total to zero, rotate the reset knob.

DO NOT let the pump run dry or run in by-pass mode for more than 2 minutes or damage may occur.
1. Before use, wipe off any dirt or moisture that may have accumulated on the nozzle or hoses.
2. Insert nozzle into the container to be filled. Insert suction hose (if applicable) into the diesel storage tank.
3. Switch the motor on. 4. Operate the nozzle lever to dispense fluid. 5. When the desired amount of fluid has been dispensed,
release nozzle lever to stop flow. 6. Immediately switch motor off. 7. Nozzle and hoses should be kept clean and dry when
not in use.
MAINTENANCE
Important: Do not modify any part of the unit or any warranty on the product will be automatically void.
1. Inspect and clean the basket strainer located in the pump regularly. 2. Always clean the battery terminals and clips before use
to ensure a good connection. 3. Always relieve the line pressure by opening the nozzle,
draining hose. Disconnect power before starting any pump maintenance 4. Hoses should be inspected regularly. (Replace if found to be cracked or worn) 5. The rotor and vanes will eventually wear. They should be replaced if pump performance degrades. (refer to trouble shooting guide)

METER FIELD CALIBRATION
Calibration may be required depending on installation or after disassembly, metering different fluids or where meter wear has occurred.
NOTE: You will need to use an accurate measuring container with graduations up to at least 19 litre capacity.
CALIBRATION PROCEDURE
1. Set the batch total to Zero 2. Dispense 19 liters into your accurate measuring container 3. Check the total shown on the meter and compare with the actual total dispensed as shown in the container. 4. Adjust the calibration screw as required a) Turn the screw anti-clockwise to reduce the indicated amount b) Turn the screw clockwise to increase the indicated amount
Note: One full turn of the screw will change the indicated amount approximately 2 liters
5. Repeat steps 1 – 4 until meter calibration is acceptable.
