Section 2: INTRODUCTION
Quantum Energy Technologies
2a:
One Of The Worlds Most Energy Efficient Methods Of Water Heating Production
We thank you for your decision to purchase a Quantum Energy Technologies Heat Pump Water
Heater, which will reward you with many years of low energy hot water production.
QUANTUM ENERGY TECHNOLOGIES Pty Ltd designs and manufactures energy efficient Heat
Pump water heaters. The simple way to explain the advantage of this heater is that it saves energy
in any weather, even at night.
The Compact models use 1kW of electrical energy, however, they are able to put up to 3.6kW of
heat energy into the water @ 20°C ambient. The system can save up to 75% of conventional hot
water energy utilization; greatly assisting in the worldwide greenhouse gas reduction campaign.
As the name indicates, a Heat Pump is a machine that pumps heat from a low temperature source
to a high temperature reservoir. It has a cold side to absorb heat at low temperatures and a hot side
to deliver heat at high temperatures.
The Quantum compact model has an air conditioning coil as the cold side of the refrigeration
circuit. This coil absorbs the heat from air that is forced through it by means of the fan. The
Compact design is installed like a conventional electric water heater i.e. the electrical and
plumbing is completed in the same manner.
There is also a Split Air Sourced design, which can be used to recover heat from the roof space or
a warm area like a kitchen. The remote fan coil (energy collector) operates like a passive solar
collector, for instance, absorbing the heat energy from the warm air in the roof space (which has
been heated by the sun). Alternatively, the waste heat from the building can be used as the heat
source.
QUANTUM water heaters are designed and manufactured in Australia and can save energy in
countries all around the world. They are used in all weather conditions for domestic, commercial
and industrial applications, and are regarded as one of the most energy efficient water heaters
available.
This is your assurance that you have purchased one of the highest quality water heaters on the
market, one that will provide continuous hot water for all your needs – safely, economically, and
for many years to come.
2b: Time Delay On Start
NOTE: The system has a 10-minute time delay on start or restart. When the power is first
connected or after a disconnection then re connection, the time delay on start will commence. The
compressor and fan will not operate until the completion of this delay period.

resistance and longer life.
2. Indirect heat transfer eliminates tank hot spots.
3. One of the most energy efficient Heat Pump systems in the world.
4. Able to save more money, especially in cold weather, than any other solar system on the
market.
Warranty Return Card
Enclosed you will find a warranty card – please fill in the details and return immediately. This will
ensure prompt service under warranty, if required (see Section 8 for terms of warranty).
Section 3: INSTALLATION DETAILS
3a: General Installation Requirements
This water heater must be installed by a licensed tradesperson, and in accordance with
1. AS 3500.4, National Plumbing And Drainage Code, Part 4: Hot Water Supply Systems.
2. AS 3500.4.2, National Plumbing And Drainage Code, Part 4.2: Hot Water Supply Systems
– Acceptable Solutions.
3. Other relevant Australian Standard, Industry or Local Water Supply regulations or codes
for mains pressure storage tanks.
Note: This water heater is not suitable for pool heating or building heating.
3a.1: Location
The water heater should be located as close as possible to the most frequently used hot water
outlets. Adequate access must be made for service to the evaporator, water temperature thermostat,
relief valve and anode. Ensure that the specification label is clearly visible. The front service cover
of the heat pump section (on top of tank) must be accessible from the front of the heater; this must
NOT face the wall. The fan MUST NOT be up against a wall (minimum clearance 500mm).
The Compact model has a noise level similar to an air conditioner (52dBA @ 1.5 metre); therefore
locating the unit away from bedrooms or living areas is recommended (both the owners & any
neighbours). Obviously installing near a bedroom window may be annoying to the occupants.
Note: All models are equipped with a sacrificial anode, accessible through the top cover. We
recommend allowing 400mm above the top of the water heater (if possible) for clearance to
replace the anode.
The water heater should be placed on a 650mm x 650mm plinth if installed on a floor subject to
wet conditions or outdoors. A properly drained overflow tray should be used where property
damage could occur from water spillage. (See AS3500.4 for further details.)
Note: The warranty does not cover damage due to leakage of the water heater
Document number: QDC0030PD-11 Page 7 of 40
Owner’s Manual Quantum Energy Technologies
3a.2: Corrosion Protection
Fittings and the Shell Surface in contact with the water are to be galvanically compatible. Sealants
and / or Teflon plumbing tape should be used on potentially galvanically incompatible fittings.
This is to protect against possible electrolytic corrosion between the metals (where moisture
penetration could occur due to incorrectly or poorly sealed fittings).
3b: Air Flow
The Compact and Split Air models extract the required heat from air being drawn through their Fin
Coil Evaporator. This produces cold exhaust air as a by-product. In order for the heaters to operate
efficiently, good ventilation of the proposed location for the Compact model or the Titan models
separate evaporator is required. This is to provide warm air as a heat source and to remove the cold
air being produced. The Compact therefore is best located externally, however a large double
garage (minimum of 120 cubic meters) may also be suitable. The Titans separate evaporator could
be located externally or in a large well-ventilated ceiling space or garage, however being a more
powerful system, more ventilation is required.
3c: Evaporator Drain
During operation considerable amounts of condensate water will flow from the evaporator drain. If
allowed to simply flow out of the outlet, this water may pool below the unit and can cause
problems to both the water heater and area around it. The evaporator drain on both the Compact
and Split Air units should be drained to a suitable location. This can be accomplished with a length
of hose or pipe but must not be connected directly to the PTR valve or expansion valve drain.
3d: Pressure & Temperature Relief Valve (PTR)
The Pressure and Temperature relief valve (see tank data plate for rating), which is supplied with
the unit, must be fitted and made accessible so that the release mechanism can be operated and, if
required, the valve replaced. The outlet of the PTR valve must be suitably drained to remove the
water discharged during the normal heating cycle. The valve thread is RP ½” / 15mm and must be
installed into the top front socket.
Warning: A separate drain line must be run for this relief valve. It is not permitted to couple the
drain lines from the relief valve and evaporator into a single common line. The use of a tundish
under the evaporator drain with this then connected to the drain of the PTR valve is acceptable.
3e: Expansion Control Valve (ECV)
Where an Expansion Control Valve is fitted to the cold water supply, the ECV should be rated at
150kPa lower than the Pressure & Temperature Relief valve (PTR). It is a State requirement for
SA & QLD that an ECV be fitted on the cold water supply line between the non- return valve
and the water heater.
Document number: QDC0030PD-11 Page 8 of 40
Owner’s Manual Quantum Energy Technologies
3f: Cold Water Connection
An approved isolating valve, approved non-return valve, line strainer (optional but recommended),
and union must be fitted between the supply main and the RP ¾ / 20mm socket in the water heater.
All fittings must be approved by the relevant Authority (refer to Figures 1 & 2).
3g: Pressure Reducing Valve
This water heater is designed for direct connection to a maximum water supply pressure of 500
kPa. Where the mains pressure can exceed or fluctuate beyond this pressure, a pressure-limiting
device (complying with AS1357) must be fitted in the cold-water supply line. This device must be
installed after the isolating valve and set at or below 500 kPa (350 kPa if ECV fitted). With a water
supply pressure of 700 kPa, as the tank temperature reaches 55°C, the internal pressure climbs to
1100 kPa (well above the PTR valve rating). Given this 400 kPa rise, even with a 500 kPa supply,
the internal pressure could still reach 900 kPa.
3h: Caution Regarding Glass Lining Of Tank
When making the hot and cold water connections to the tank care should be taken not to apply
excessive strain as damage to the tank spigots or glass lining may occur.
3i: Suitability For Installation In Frost Areas
The R134a refrigerant used has a boiling point of –26°C so there is no risk of damage to the heat
pump from frost. Performance may be reduced in very low temperatures but the system will not be
damaged by such climatic conditions.
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). For the most
economical operation of the water heater, 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 tape is applied to the plugs for a tight, leak proof seal.
3l: Tempering Valves
Where a tempering valve is fitted on the hot water outlet of a Quantum (to reduce water
temperature to 50°C as per the plumbing code) ONLY high performance valves suitable for
“Solar” type water heaters are recommended to be used. Standard tempering valves may not
function correctly.
Document number: QDC0030PD-11 Page 9 of 40
Owner’s Manual Quantum Energy Technologies
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.

If installing multiple Compact un its, the orientation of the tank will need to be at 90° to the normal arrangement
so that the fan points out from the wall rather than along it. This is so tha t cold air being discharged from one
unit is not drawn in by the one next to it. The space between multiple units should be a minimum of 200mm.
