3j: Draining Of Tank
Consideration should be given to the possible necessity of draining the tank at some point.
Draining of the tank can be accomplished by the connection of a hose to the cold water inlet and
running to a suitable drain. It will be necessary to disconnect the hot water outlet or PTR valve to
relieve any partial vacuum created as the water flows out.
3k: Hot Water Connection
The hot water pipe should be connected to the RP ¾ / 20mm socket as shown in the Installation
Diagram (Figures 1 & 2). If desired, a thermo siphon trap can be installed at the hot water outlet
to further reduce heat loss (a “U” shaped loop will form such a trap – see Figures 1 & 2). It is
recommended that all hot water lines be insulated. NOTE: Plugs are supplied with the water
heater to plug off the inlet / outlet entries that are not required. Ensure that adequate sealing is
applied to the plugs for a tight, leak proof seal.
3l: Tempering Valves
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 plumbing code). The high
performance valves suitable for “Solar” type water heaters are recommended to be used. Standard
tempering valves may also be used, but it may be not function as well as the high performance
ones.
3m: Electrical Connection
Quantum water heaters are designed for single-phase 220/240V 50Hz A.C supply only. All
electrical work must be conducted by a certified electrician according to the local regulations and
AS3000. A 10 or 15-amp circuit breaker must be installed at the power supply for the hot water
units up to 0.8kW or 1.7kW, respectively. The power connection rating for Quantum water
heaters up to 1.1kW is 220-240VAC 50Hz 10A, and 15A for the 1.7kW models.
A separate circuit breaker is recommended for each unit in the case of multiple installations.
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 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
