Section 2: INTRODUCTION
QUANTUM ENERGY TECHNOLOGIES
2a: One Of The World’s 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.
For example, one of the models uses 1kW of electrical energy, however, they are able to put up to
3.6kW of heat energy into the water with 20°C ambient air. The system can save up to 75% of
conventional water heater’s energy utilisation; 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.
Quantum heat pump water heater 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 connections are completed in the same manner.
There is also the Split design, which can be used to recover heat from a warm area like the roof
space or the kitchen. The remote fan coil (energy collector) absorbs the heat energy from the
warm air. Alternatively, the waste heat from the building can be used as the heat source.
QUANTUM heat pump water heaters 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 the most energy efficient and practical water heaters available.
This is your assurance that you have purchased one of the highest quality water heaters on the
market and the 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 occur. The
compressor and fan will not operate until the completion of this time delay period.
2c: Features Of Your Quantum Water Heaters
1.
Fully welded steel tank with class X vitreous enamel lining for superior corrosion
resistance and longer life.
2.
Indirect heat transfer eliminates cross contamination and tank hot spots.
3.
No electrical element. The safest and one of the most energy efficient Heat Pump systems
in the world, especially in cold weather, the efficiency is higher than any other solar/heat
pump systems on the market.
4. Able to save more money than any other solar/heat pump systems on the market.

Warranty Return Card
Enclosed you will find a warranty card – please fill in the details and return to Quantum. 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 and New Zealand 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 heat pump, water 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’s outdoor unit (52dBA @ 1.5
metre); therefore locating the unit away from bedrooms or living areas is recommended (both the
owners & any neighbors).
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
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 air source models (compact and split) 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 models or the
split 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) with some natural ventilation may also be
Document number: QDC0030PD-16.4
Page 7 of 36
Owner’s Manual
Quantum Energy Technologies
acceptable. The separate evaporator in the split models could be located externally or in a large
well-ventilated ceiling space or garage.
3c: Evaporator Drain
During operation a certain amount 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 the water heater and/or 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.
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 800kPa.
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 500kPa (or 350kPa if a 850kPa expansion
control valve fitted). An ECV is fitted when the water supply has a tendency to form scale. This
type of water is referred to as scaling water because calcium carbonate is deposited out of the
water onto any hot metallic surface. The fitting of an ECV is mandatory in WA, SA and some other
areas of Australia as dictated by local regulations.
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.

NOTE:
In installing single Compact units, the fan should point out from, or along, the wall.
If the fan has to point towards to the wall, the distance between the unit and the wall should be at a
minimum of 500mm.
In installing multiple Compact units, the fan should not point out to the unit adjacent, so that 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 for air flow, but 500mm is recommended
for the convenience of service.

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

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 9m.
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.

Section 4: OPERATING INSTRUCTIONS
4a: Filling The Water Heater
Open all hot water taps. Open isolating valve at the cold-water inlet and allow the water heater
to fill until water flows through the system. Close each hot water tap after the air is expelled from
its line.
4b: Water Quality
Your Quantum water heater has been manufactured to suit the water conditions of most Australian
and New Zealand metropolitan supplies. Please note that harsh water supplies can have a
detrimental effect on the water heater and its life expectancy. If you are unsure about your water
quality you can obtain information from your local water supply authority.
By using the correct anode this water heater can be used in areas where the Total Dissolved Solids
(TDS) content of the water supply is up to 2500 mg/L. In areas where the TDS exceeds 750mg/L it
is possible that the magnesium alloy anode (supplied in the heater) may become over reactive. To
alleviate this, the magnesium alloy anode should be replaced with an aluminum alloy anode
(Note: Quantum does not supply this).
4c: Caution When Left Operating But Unused
If the water heater is left in an operating condition but unused for two weeks or more, a quantity
of hydrogen gas (which is highly flammable) may accumulate in the top of the water cylinder. To
dissipate this gas safely it is recommended that a hot tap be turned on for several minutes at a sink,
basin or bath, but not a dishwasher, clothes washer or other appliance. During this procedure there
must be no smoking, open flame or any other electrical appliance operating nearby. If hydrogen
gas is discharged through the tap it will probably make an unusual sound similar to air escaping.

Section 5: SAFETY INFORMATION
DO NOT TURN ON POWER UNLESS THE TANK IS FULL OF WATER
5a: Safety Devices
WARNING: For safe performance this water heater is fitted with:
1.
Digital Controller.
2.
A thermostat (connected to the digital controller) to manage water temperature.
3.
A thermostat (connected to the digital controller) to manage compressor temperature.
4.
A non self-setting thermal cut out (incorporated into the digital controller).
5.
Combination Pressure & Temperature relief valve.
These devices must not be tampered with or removed.
The water heater must not be operated unless each of these devices is fitted and in working
order.
This appliance is not intended for use by young children or the infirm without supervision –
young children should be supervised to ensure that they do not play with the appliance.
5b: Important Note Regarding PTR Valve
The Pressure & Temperature relief valve should be checked for adequate performance or replaced
at intervals not exceeding 5 years, or less in areas where there is a high incidence of water
deposits. Providing there is some discharge from the relief valve during each heating cycle there
is no requirement to manually activate the release mechanism on the relief valve. There is a
possibility that manually opening the relief valve may allow contamination / grit etc to settle in
the valve seat causing continuous leakage. If the relief valve is operated manually it should be
done with care.
The Pressure & Temperature relief valve and the drain outlet pipe must not be sealed or blocked.
It is normal for small amounts of water to leak from the valve during each heating cycle.
Section 6: MAINTAINANCE & SERVICE INFORMATION
Your Quantum water heater is a completely sealed refrigeration system, similar to a household
refrigerator. The maintenance program to be employed on your Quantum is not much different to
that required for the maintenance of a standard electric water heater. However, Quantum
warranty may be void if any of the following conditions are not met or if the refrigeration
lines or components are damaged or altered in any unauthorized way.
6a: The Water Tank
The water tank must not be drilled or punctured. Drilled holes or punctures may damage the
refrigeration pipes located on the skin of the water tank. The Quantum tank is a patented design
and in fact forms the condenser of the unit; i.e. it is the hot side of the refrigeration circuit. The
coils wound around the outside wall of the tank heat the tank more efficiently than any other
water heater design. The coils are not in contact with the water so they never corrode or suffer
from scaling, meaning the efficiency of the tank will not diminish.

6b: Air Evaporator Coils
Quantum water heaters use evaporator coils to extract heat from the air. The coil is extremely
efficient in warm humid weather; however, as temperatures drop to ten degrees or less the coil
will begin to collect ice. The coil has been designed with "heat injection" to defrost the coil under
such conditions. The heat injection cycle is automatic and is managed by the digital controller. It
is important that the air inlet vents are kept clean. Restriction of air-inlet or outlet vents
may void warranty if the system has been damaged because of insufficient airflow.
6c: Sacrificial Anode
A sacrificial anode is fitted inside the vitreous enamel lined cylinder. Its purpose is to help protect
the cylinder from the corrosive effects of water. Normally, the sacrificial anode should be
inspected every fifth year and replaced if necessary. In areas where “hard water” or poor quality
water conditions exist, the sacrificial anode must be inspected every second year. Replacement
anodes must meet Quantum quality specifications and must be appropriate for local water
conditions. The anode socket in the top of the tank is an RP 3/4 / 20mm thread, an 11/16” socket
wrench is required to unscrew it
6d: Service Caution – Before Any Work Is Carried Out
Before any electrical components are inspected the System MUST be turned off at the power
switch / hot water circuit breaker. Do not touch wiring or any electrical components without
supervision or training to Australian (or equivalent) standards.
6e: Thermal Overload (Incorporated in Digital Controller)
All models are fitted with a digital controller for heat pump management. One function of the
digital controller is to initiate a shut down and lockout if the compressor reaches a temperature of
105°C. The system will not automatically restart from this. To reset the system the “SET”
button on the digital controller must be pressed (hold for 6 seconds). Turning the power off then
back on will also perform a reset.

6f.1: Six Month Service (By Owner)
To be carried out every six months. Operate the Pressure & Temperature relief valve for
approximately 10 seconds by activating the release mechanism on the valve to ensure water is
released to waste through the relief drainpipe.
Document number: QDC0030PD-16.4
Page 14 of 36
Owner’s Manual
Quantum Energy Technologies
It is very important that the mechanism is operated gently. Check to ensure the valve closes
correctly.
Note: providing some hot water discharge has been observed from the relief valve during normal
heating cycles, manually activating the valve is not necessary and could cause contamination / grit
to lodge in the relief valve seat causing constant leakage.
An inspection for any obvious signs of corrosion of the outer case or air intake grills should also
be conducted.
6f.2: Five Year Service (By Authorized Personnel Only)
The five-year service should be carried out by a licensed tradesperson every five years. It is
recommended that your local Quantum distributor or service agent carry out this service. The
service should include the following: 1.
Replace the Pressure & Temperature Relief valve.
2.
Replace the anode.
3.
Flush the water heater.
4.
Checking of the refrigeration system.
5.
Checking of thermostats, digital controller and electrical components.
If in doubt, contact Quantum Energy Technologies for your nearest distributor or service agent.
Our website www.quantumenergy.com.au and www.quantumenergy.co.nz also provide an up
to date list of Quantum distributors.
6f.3: Access & Removal Of Sacrificial Anode
The anode can be accessed via the heat pump section, to remove.
1.
Turn off power to the unit, cut into water valve, open PTR valve to release pressure on the
system.
2.
Remove the screws around the top cover of the heat pump & remove the heat pump top
cover.
3.
For easier access the front inspection panel on the heat pump section should also be
removed.
4.
Locate and remove the plastic plug through the centre of the heat pump chassis.
5.
The anode head is now accessible and can be unscrewed with a suitable 11/16” socket
wrench.
6.
Once unscrewed the anode can be drawn out through the top of the tank / heat pump
section.
7
The new anode can then be fitted and the heater reassembled.
6f.4: Flushing Of Water Tank
As with other hot water heater tanks, dissolved solids in the water or scale may accumulate in the
bottom of the water tank forming sludge. This is generally less of a problem with Quantum units
as no internal elements or burners are used.
If such sludge build-up does occur the following procedure can be followed to clean out the tank.
1. Turn Off power to the unit.
2. Turn Off water supply to the unit.
Document number: QDC0030PD-16.4
Page 15 of 36
Owner’s Manual
Quantum Energy Technologies
3. Remove the blanking plug (brass fitting) from the unused inlet (normally on the right
hand side for left hand connected tanks) – the inlets are at the bottom of the tank 70mm up
from the base.
4. Remove the blanking plug from the unused hot water outlet (normally on the right hand
side for left hand connected tanks) – the outlets are at the top of the tank.
5. Allow the water to drain from tank, while the water is draining a non-metallic rod may be
inserted through the open cold-water inlet and used to break up any sludge and assist in its
removal.
6. Care should be exercised during this procedure so as not to damage the glass lining of the
tank. The use of metal rods should not be used and plastic or wooden rods used instead.
7. Turning the cold water supply back on while the tank is emptying or after the tank has
drained and continuing with the mechanical agitation will further assist with the removal
of the sludge.
8. Once the tank has been cleaned, as much as possible, the cold water should be turned off
again and the blanking plugs refitted. Care should be taken to ensure good a hydraulic seal
is maintained – the use of plumbing tape will be required.
9.
When the unit is fully reassembled the cold water supply and power supply can be turned
on and the unit allowed to reheat.
6f.5: Refrigeration & Thermostat Servicing
Qualified refrigeration technicians only should service the heat pump. The information provided
in Appendix A: Trouble Shooting Guide will provide the necessary information for qualified
personnel to service this part of the unit.
Section 7: RECOGNITION OF ABNORMAL OPERATION
7a: Pressure & Temperature Relief Valve Running
It is not unusual for the Pressure & Temperature Relief valve to allow a small quantity of water to
escape during the heating cycle. The amount of discharge will depend on hot water usage. As a
guide, if it discharges more than 20 litres of water in 24 hours then there may be a problem.
7a.1: Continuous Trickle
Likely caused by a build up of foreign matter. Try gently operating the release mechanism on the
Pressure & Temperature Relief valve for a few seconds. This may dislodge any small particles of
foreign matter and rectify the fault.
7a.2: Steady Flow
Likely causes are excessive water supply pressure (500kPa Pressure Limiting valve should be
fitted), a faulty Pressure & Temperature Relief valve, a faulty or non existent pressure limiting
valve or a faulty Thermostat / Digital Controller. Turn off the electricity supply and contact your
Quantum distributor or service agent.
7b: No Hot Water
1.
Is the Electricity switched on? Check that the isolating switch, to which the Quantum
is connected, is on. Check that the switch marked “Water Heater” in the switchboard is
on. Are all circuit breakers on? If on Off Peak, is the meter switching on when it should?
If the system is connected to some form of Off Peak metering, running out of hot water
Document number: QDC0030PD-16.4
Page 16 of 36
Owner’s Manual
Quantum Energy Technologies
can be quite common – Off Peak tariffs are not recommended for Quantum water heaters.
2. Check that the thermal overload (on the digital controller) has not been tripped. If so
press the “Set” button (hold for 6 seconds) to reset it.
3.
Is the Pressure & Temperature Relief valve discharging too much water? See Section 7a:
"Pressure & Temperature Relief Valve Running".
4. Do you have the correct size water heater for your requirements?
available from your Quantum supplier.
5.
Sizing details are
Is one outlet (such as the shower) using more hot water than you think? Carefully
review the family's hot water usage and if necessary check the shower flow rates with a
bucket and a watch. If it is not possible to adjust water usage patterns, an inexpensive
flow control valve can easily be fitted to the shower outlet.
7c: High Electricity Bills
1.
Is the Pressure & Temperature Relief valve discharging too much water?
7a: "Pressure & Temperature Relief Valve Running”.
2.
Is one outlet (such as the shower) using more hot water than you think?
"No Hot Water”.
See Section
See Section 7b:
3.
Is there a leaking hot water pipe or dripping hot water tap? A small leak can waste a large
quantity of hot water.
4. Replace faulty tap washers and have your plumber rectify any leaking pipe work.
5. Have any new appliances been installed that might be using the extra power?
6.
If there are no water leakages around the building and no excessive usage of hot water, yet
electricity bills are higher than normal (without any other appliance being responsible)
then it may indicate a problem with the water heater. Contact your nearest Quantum
distributor or service agent.

A.5: Testing Undercharge Or Overcharge Of Refrigerant
Unlike normal refrigerating or air conditioning systems, the QUANTUM heat pump operates under a very
wide range of evaporating and condensing temperatures. To identify undercharge or overcharge of
refrigerant gas in the system, three parameters need to be checked.
1.
Current Draw
2. System Pressures
3. Bubbles through sight glass on the receiver / filter-dryer

A.8: Signs Of Correct Charge
During normal operation with the correct amount of refrigerant gas, the sight glass should show clear
liquid. A very few small bubbles may be present when the system is started or when the TX valve opens
quickly. But it should return to clear liquid shortly after. Current draw and delivery pressure will be within
the nominal range and temperatures should be consistent with gas properties. Correct amount of charge is
listed in the Table A10.
A.9: Signs Of Undercharge
When bubbles through the sight glass persist for a significant time or repeat frequently then it is a sign of
refrigerant undercharge. This can be confirmed by a low current draw together with low pressures. Note
that unusual current draw could also be a sign of other defects in the system. If the sight glass shows clear
gas (not liquid), current draw is too low and discharge gas is not hot or suction pressure too low then the
system is nearly or totally empty.
Note that low suction pressure could also indicate a blockage in low-pressure side or a closed TX valve.
A.10: Signs Of Overcharge
Continuous liquid through sight glass: Assuming TX valve is functioning normally, evaporator tends to
flood, head pressure tends to be high, current draw is high and compressor is noisy.
