The power supply to the water heater must not be switched on until the 
water heater is filled with water and a satisfactory megger reading is 
obtained. 
 
All electrical work and permanent wiring must be carried out by a qualified 
person and in accordance with the Standards Australia Wiring Rules 
AS/NZS 3000 and local authority requirements. 
 
WATER HEATER 
A water heater not fitted with a supply cord and plug must be directly connected 
to a 240 V AC, 50 Hz mains power supply with an isolating switch installed at 
the switchboard. A water heater fitted with a supply cord and plug must be 
plugged into a switched 240 V AC, 50 Hz mains power outlet rated at 10 A. 
 
The power supply to a 

 should be Off-Peak (overnight) to 

the 

 and continuous to the 

. The power 

supply to a 

 can be either an 

, 

 electricity supply, 

depending upon the size of the water heater. Check with the local electricity 
supply authority as to their requirements. An Off-Peak (overnight) power supply 
will provide the maximum financial savings. Discuss the power supply 
requirements with the householder. 
 
A flexible 20 mm conduit is required for the electrical cable to the water heater. 
The conduit is to be connected to the unit with a 20 mm terminator. Connect 
the power supply wires directly to the terminal block and earth tab connection, 
ensuring there are no excess wire loops inside the front cover. 
 
THERMOSTAT SETTING 
The thermostat on a Rheemglas and RheemPlus model is adjustable from 
60

°C to 70°C (60°C to 75°C on a 50 litre model) and on an Optima model from 

60

°C to 75°C. The thermostat is adjusted by turning the adjuster 

(Rheemglas / RheemPlus model) or knob (Optima model) anticlockwise to 
decrease the temperature setting and clockwise to increase the temperature 
setting. Only adjust the thermostat setting on a Rheemglas and RheemPlus 
model when the isolating switch is switched off at the switchboard. The top 
thermostat on a twin element model is fixed at 60

°C. 

 
For reasons of safety and economy, we advise the thermostat be set at the 
lowest temperature that will provide sufficient hot water. Dishwasher running 
costs can be adversely affected if the thermostat is set below 65

°C. If this water 

heater is installed as part of a solar water heating system, we recommend the 
thermostat is set at 60

°C to maximise solar contribution. Discuss the thermostat 

setting requirements with the householder.
