Section 3: Pump Operations
12/24 VDC and 110/230 VAC Operations
Before refuelling, the pump skid and the aircraft must be properly grounded. Proper grounding means
continuous metal to metal contact between the pump skid and the aircraft or power supply.
To turn the pump on, use the switch at the top of the pump motor.
The pump will self-prime dry to a height of 150 cm. Once the pump is primed, it should lift up to a maximum
suction height of five meters, depending on pump specifications. If the pump fails to prime, refer to
Section
4
of this manual for priming procedure.
When starting a new unit or one that has been idle for a long time, pump fuel back in to the storage tank for
several minutes. This will purge all the hoses of air and rinse out any contamination which may have entered
the system during storage or transport.
Important Note
Do not run the pump dry.
If the pump does not begin to deliver fuel within two minutes after
turning the pump on and opening the nozzle, turn the pump off and check for air leaks in the
suction line.
Caution
The duty cycle of the pump is 30 minutes on and 30 minutes off
. After pumping for a maximum
of 30 minutes, turn the pump off and allow it to cool for 30 minutes before pumping again.
