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 Wiring Rules AS/NZS 3000 and local 
authority requirements. 
 
The water heater, supplied with a 1.8 metre power cord, requires a 240 V 
general power outlet (GPO) to be located within 1.2 metres of the installation. 
The GPO is required to be weatherproof for an outdoor installation. 
 
Should it be necessary to provide permanent wiring, the water heater must be 
directly connected to a 240V AC 50 Hz mains power supply with a double pole 
isolating switch installed adjacent to and accessible from the water heater. A 
20 mm flexible 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. Ensure 
there are no excess wire loops inside the front cover. 
 
The water heater can be wired 
for use with a remote control 
thermostat or a remote time 
switch. The water heater 
thermostat should be adjusted to 
a temperature higher than the 
setting on a remote thermostat. 
 
THERMOSTAT SETTING 
The thermostat is adjustable 
from 60

°C to 82°C. For reasons 

of safety and economy, we 
advise the thermostat is set at 
the lowest temperature that will 
provide sufficient hot water. 
Discuss the thermostat setting 
requirements with a responsible 
officer. Refer to 

“Temperature 

Control”

 on page 43. 

 
If this water heater is installed as an in-series booster water heater as part of a 
commercial solar water heating system, to maximise solar contribution it is 
recommended the thermostat is set at 60

°C, unless sanitising temperatures are 

required.
