Maintenance
! IMPORTANT ! It is recommended that only qualified, experienced personnel, familiar with this equipment,
who have read and understood all the instructions in this manual should install, operate and maintain the
system.
! IMPORTANT ! Always disconnect the system from the electric power supply before working or servicing
it. Do not proceed with any maintenance unless the pressure or vacuum has been released, the system has
been allowed to reach ambient temperature and all fluids have been drained.
Draining and Storing the System
1. Set pump motor to operate at a low speed - 10-15 Hz in the Speed Indicator Window
2. Remove Suction Hose “stinger” from tank allowing air to be drawn into the system through the “stinger” (or open ball
valve to atmospheric on top of “stinger”).
3. Continue at low pump speed until the system is purged of fuel as indicated by a lack of fuel in the suction hose.
4. Purge the pre-filter: Continue at low pump speed and allow unit to clear.
5. Ensure all fuel is cleared from the HC-300.
6. Terminate pump operation when all fuel is purged
7. Disconnect all hoses and contain any fuel remaining in hoses
8. Cap hoses as appropriate
Pump
Check pump for leaks, worn vanes and if bypass valve operates correctly. Keep the pump lubricated and pour some oil into
pump head for storage.
Suction and Discharge Hoses
We recommend replacing both the suction and discharge hoses every two years. Heavy use, visual deterioration, damage
or poor condition and excessive wear can require an even earlier change.
