CLEANING AND MAINTENANCE
WARNING: MAKE SURE THAT THE PUMP IS DISCONNECTED FROM THE
MAINS SUPPLY BEFORE CLEANING, OR PERFORMING ANY
MAINTENANCE.
• The pump should require no maintenance other than regular
cleaning. Its’ mechanical seal is lubricated in an oil chamber, and its’
bearings are ‘sealed for life’. If the pump starts to show signs of wear
or damage, contact your CLARKE dealer for advice.
• Do not use the pump if there is any damage to the mains supply
cable, or to the float switch or its cable.
• Check the pump installation regularly to ensure the base inlet is clear
of leaves or other debris.
• Do not attempt to repair the pump yourself, as you may damage the
seals and invalidate your guarantee. Repairs must be carried out by
a qualified pump engineer, your CLARKE dealer, or contact the
CLARKE Service Department on: 020 8988 7400.
If the pump becomes badly clogged, the stainless steel strainer may be
removed and cleaned by removing the three screws
FROM THE BASE ONLY
.
DO NOT attempt to remove any other screws.
Backflush the pump chamber by directing a jet of clean water through the
outlet port.
WARNING: DO NOT ATTEMPT TO STRIP THE PUMP FURTHER AS THIS WILL
INVALIDATE THE GUARANTEE.
ANNUALLY OR EVERY 2000 WORKING HOURS
(Whichever is sooner)
The sealing oil must be checked by a qualified pump engineer. Consult your Clarke
dealer, or Clarke International Service Department.
