Service And Maintenance - Pentair ONGA IMH750 Owner's Manual

Service and Maintenance

Pumps should only be serviced only by qualifi ed personel. For
best results, use only genuine service parts. Be sure to prime
pump before starting.
To avoid dangerous or fatal electrical shock, turn OFF power to
pump and remove plug from outlet before attending the pump.
RCD tripping indicates an electrical problem. If RCD trips and will
not reset have a qualifi ed electrician inspect and repair electrical
system and/or pump.
If service is required to the power supply cord and/or appliance
connectors, they must be replaced with the specialised cord
assemblies by Pentair Water service agent or similarly qualifi ed
personnel in order to avoid a hazard.
Liquid may be HOT, release pressure with care before
servicing.
1. General Care and Maintenance
Under normal conditions the Onga IMH series of pumps requires only minimal
attention. A six monthly check of the general condition of the pump and
plumbing is recommended.
In order to prevent possible failures, it is advisable to periodically check the
pressure supplied and power absorption is also carried out. A decrease in pressure
is a symptom of wear. An increase current absorption is a sign of abnormal
mechanical function in the pump and/or motor. If these symptoms occur, take your
pump to your nearest service agent for inspection and repair.
