Save A Service Call - Rheem Electric Domestic Water Heater Installation And Owner's Manual

Check the items below before making a service call. You will be charged for
attending to any condition or fault that is not related to the manufacture or
failure of a part.
NOT ENOUGH HOT WATER (OR NO HOT WATER)
Is the electricity switched on?
Inspect the isolating switch marked "HOT
WATER" or "WATER HEATER" at the
switchboard and the isolating switch (if one
is installed) near the water heater and
ensure they are turned on.
Note: Check the electricity supply to which
the water heater is connected. If on an Off-
Peak or time controlled electricity supply,
remember heating hours are restricted
"Off-Peak Electricity Supply"
(refer to
page 7).
Check the fuse marked "HOT WATER" or "WATER HEATER" at the
switchboard.
Twin element water heaters
A twin element non-simultaneous model must have power available to the
top heating unit circuit at all times for the water heater to operate as
designed.
Are you using more hot water than you think?
Is one outlet (especially the shower) using more hot water than you think?
Very often it is not realised the amount of hot water used, particularly when
showering. Carefully review the family‟s hot water usage. Have your
plumber fit a flow control valve to each shower outlet to reduce water usage.
Temperature pressure relief valve running
Is the relief valve discharging too much water? (Refer to
Pressure Relief Valve Running"
Thermostat setting
Ensure the thermostat setting is appropriate. You may choose (Optima
model) or have your electrician (Rheemglas and RheemPlus model) adjust
the thermostat upwards to gain additional hot water capacity. Refer to
"Temperature Adjustment"
Warning: Hotter water increases the risk of scald injury.
A RheemPlus water heater is temperature limited to 50°C at the hot water
outlet. Increasing the thermostat setting will not increase the outlet
temperature but will provide more hot water capacity.
