3m: Electrical Connection
Quantum water heaters are designed for single-phase 220/240V A.C supply only. A certified
electrician must carry out all electrical work according to the local supply authority regulations and
AS3000. A 15-amp circuit breaker must be installed at the power supply for the hot water unit.
A separate circuit breaker is recommended for each unit in the case of multiple installations. The
power connection rating for all Quantum water heaters up to 1.7kW is 220-240VAC 50Hz 15A.
It is not recommended to wire the system to an earth leakage circuit breaker. There is lot of
moisture present while in operation and this can lead to nuisance tripping.
The connection will require an approved, standard 240V 15A On / Off switch or Junction Box in
close proximity to the heater. The unit should be connected to Standard Domestic tariff. Off Peak
connection is NOT recommended for Quantum heat pump units. If the unit is connected to an “Off
Peak” connection, the minimum power availability must be at least 18 hours per day.
The fitted power cord is not to be removed; this cord should be connected with the building wiring
in an On / Off switch enclosure or Junction Box. Faulty wiring may void the warranty if damage
has been sustained to the compressor or heat pump from such faulty or sub-standard wiring.
3m.1: Safety Notes
Note.1: This water heater is fitted with a thermostat and over-temperature energy cut-out (both
incorporated into the digital controller). Under no circumstances should the water heater be
operated without both of these devices being in the circuit. Only a qualified electrician or the
manufacturer should carry out replacement.
Note.2: If the supply cord is damaged, the manufacturer or its service agent or other similarly
qualified person must replace it in order to avoid hazard.
Caution: The water heater must be filled with water before turning on the electricity
3n: Refrigeration Connections (Split Models Only)
Refrigeration pipe work is very specialized and should only be completed by a licensed
tradesperson.
Maximum refrigeration pipe length from the tank connections to the evaporator is 10m.
If the evaporator is mounted below the tank connection point, then a suitable oil trap needs to be
installed on the suction line between the evaporator and the heat pump.
