Preventative Maintenance - Rheem 325 II Series Service Instructions Manual

PREVENTATIVE MAINTENANCE

It is suggested that the water heater be serviced annually, to retain optimum
performance.
Annual Service
Check for discharge from the T&PR valve. When the heat pump or element is
operating a small discharge of water may be evident. Operate the valve, easing the
lever to ensure the valve opens and reseats properly. Always open and close the
valve gently.
Check for leaks at all fittings.
Check for signs of excessive corrosion on the water heater and heat pump jackets.
Check for sludge build up and if necessary drain and flush tank.
Clear the circulator impellor & ensure free rotation.
Clean the condensate tray and check the condensate drain for blockages – clear if
necessary.
RheemPlus models: Service the tempering valve, refer to page 61.
Clean blockages and debris from evaporator fins, fan blades, grilles and louvers.
Isolate power to the water heater and check all electrical connections for signs of
overheating due to poor connection.
Conduct an 'Electrical Insulation Test' on the water heater, refer to pages 40 and 55.
Check for vibration or excess noise from the compressor, fan and circulator.
Check the refrigerant charge by inspecting the sight glass.
Visually check the unit for any potential problems.
Confirm correct heat pump module operation.
Five Year Service
Replace the T&PR valve.
Inspect and flush the expansion control valve (if fitted). If required, replace the valve.
Inspect and if required, replace the anode.
If the anode is not replaced, it should be replaced within three years of this service.
Check the heating element for excessive calcium build up or corrosion and replace if
necessary.
Check for leaks at all fittings.
Check for signs of excessive corrosion on the water heater and heat pump jackets.
Check for sludge build up and if necessary drain and flush tank.
Clear the circulator impellor & ensure free rotation.
