MINOR MAINTENANCE EVERY SIX MONTHS
It is recommended minor maintenance be performed every six (6) months. Minor maintenance can be
performed by the dwelling occupant.
Switch off the electrical supply at the power outlet to the water heater prior to performing general
maintenance. This will prevent the water heater from operating while you clean or spray around the water
heater. Switch on the electrical supply at the power outlet to the water heater when finished performing the
general maintenance.
The minor maintenance includes:
•
Operate the easing lever on the temperature pressure relief valve. It is very important the lever is
raised and lowered gently. Refer to
Warning: Water discharged from the temperature pressure relief valve drain line will be hot.
Exercise care to avoid any splashing of water by standing clear of the drain line's point of discharge
when operating the valve's easing lever.
•
Operate the easing lever on the expansion control valve. It is very important the lever is raised and
lowered gently. Refer to
If water does not flow freely from the drain line of either the temperature relief valve or expansion control
valve when the easing lever is operated, phone Rheem Service or their nearest Accredited Service
Agent / Centre to arrange for an inspection.
•
The jacket of the water heater can be cleaned with a soft cloth and warm mild soapy water if required.
Under no circumstances should abrasive materials or powders be used.
•
Inspect around the air inlet and outlet louvres and the water heater in general for plant growth.
▪
Trim back any shrubs, bushes or other plants which have encroached around the water heater.
Plant growth across the air inlet and outlet louvres can interfere with the performance of the water
heater.
•
Inspect around the water heater for infestations of insects, such as ants. Insects encroaching into or
nesting in the water heater can interfere with the operation of the water heater and also damage
components. The area around the water heater can be sprayed with insecticide to rid the area of
insects.
Warning: Do not spray insecticide near the water heater while the heat pump is operating.
▪
If necessary to rid the area of insects:
➢
Ensure the electrical supply at the power outlet to the water heater has been switched off.
➢
Spray the affected are, taking care not to spray into the air inlet or outlet louvres or onto the
surface of the water heater.
➢
Wait a few minutes to allow any aerosol gases to dissipate before switching on the electrical
supply at the power outlet to the water heater.
•
Inspect and check the condensate drain hose.
Remove the drain hose from the drain spigot towards the rear of the heat pump. Use a garden hose
◼
to run water through the drain hose and dislodge any foreign bodies. Reconnect the drain hose to
the drain spigot. Ensure the garden hose and drain hose are well clear of the heat pump and its
components.
