COMMERCIAL INSTALLATION GUIDE

2k: Tempering Valves

a. The tempering valve should be fitted on the hot water outlet of the Quantum units to reduce

water temperature to the temperature designated in (e.g., 50°C as per the Local plumbing code

and all Federal, State requirements.

b. Quantum recommends the use of high performance valves suitable for “Solar” type water heaters.

2l: Electrical Connections

a. Quantum water heaters are designed for single-phase 220/240V 50Hz A/C supply only. All electrical work must

be conducted by a Quantum accredited /certified electrician according to the local regulations and AS3000. When

connecting to a Light/Commercial Titan unit a 15-amp circuit breaker must be installed at the power supply for the

hot water units. The power connection rating for Quantum Domestic water heaters up to 1.1kW is 220-240VAC 50Hz

10A. For ALL Titan Commercial model installations 1.7kW is 220-240VAC 50Hz 15A.

b. A separate circuit breaker must be installed for each unit in multiple installations.

c. 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.

d. The connection will require an approved, standard 240V On/Off switch or Junction Box in close proximity to the

heater. The unit should be connected to Standard Commercial tariff. Off Peak connection is NOT recommended for

Commercial Quantum heat pump units.

e. 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 WILL void the warranty if damage has been sustained to the

compressor or heat pump from such faulty or sub-standard wiring. *Please note that your Quantum Heat Pump

is now fitted with a Digital Timer. (Not all models). For further information please contact the Quantum

Service Call Centre on 1800 644 705.

2l1: Safety Notes

Note.1: This water heater is fitted with 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 a Quantum Technician or accredited Service Agent should carry out

replacement.

Note.2: If the supply cord is damaged, a Quantum Service Technician or its accredited Service agent /qualified

Electrician must replace it, in order to avoid hazard.

Caution: The water heater must be filled with water before turning on the electricity

2m: Refrigeration Connections (Split Models Only)

a. Refrigeration pipe work is highly specialised and should only be completed by a licensed refrigeration mechanic.

b. Maximum refrigeration pipe length from the tank connections to the evaporator is 8m.

c. 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.
