WARNINGS
Eco Alliance Heat Pump units are subject to different installation regulations across different states in Australia. We will leave the decisions
with you on how to proceed when installing the units ordered to best meet the regulations. Some best practice suggestions are below. They
are only a minimum requirements and not limited to other regulations and practices you need to adhere to.
FOR THE CONTINUED SAFETY OF THIS APPLIANCE, IT MUST BE INSTALLED, OPERATED AND MAINTAINED IN ACCORDANCE WITH THE
MANUFACTURER’S INSTRUCTIONS. PLEASE READ AND UNDERSTAND THIS MANUAL. IF YOU HAVE ANY QUESTIONS, PLEASE CONTACT OUR
LOCAL DISTRIBUTOR.
WARNING Hot water burns! For safety, small children should be supervised around hot water appliances.
Since heat pump water heaters can generate water temperatures more than 50 degrees Celsius, regulations require that a regulating valve be
installed on the hot water outlet lineof the water heater, to prevent the water temperature from exceeding a pre-set safety upper limit.
Water temperatures over 50 degrees Celsius can cause scalding, so care must be taken to ensure that damage is not caused by improper use
of the water heater.
The installation must be performed by an authorized plumber with a gas handling license and maintained within requirements specified in of
The Australian Plumbing Code. In case servicing the electrical or refrigeration systems in the Heat Pump please note, all service and repair
work must be completed in accordance with the Australian/New Zealand Standard™All electrical work should be completed to the relevant
Australian Standards. The following Product Manual is a guide to the best practices regarding technician installation, service, and repair.
A heated water service means the point where the water heater connects to the cold-water service downstream of the isolation valve. Under
no circumstances should "home craft" type modifications be attempted. Children should be supervised by a responsible person to ensure their
personal safety. The system shall be leak-tested on completion of charging but prior to commissioning. A follow up leak test shall be carried
out prior to leaving the site. Before carrying out this procedure, it is essential that the technician is completely familiar with the
equipment and all its details The hot water pump power supply must be protected by a separate circuit breaker on the main power switch
board and rated to suit the size of the components. Do not connect other appliances, especially high-power appliances, to the main power
supply of the water heater, so as not to affect the normal use of the water heater Do not use means to accelerate the defrosting process
or to clean, other than those recommended by the manufacturer. Do not install next to open flames, an operating gas appliance, or an
operating electric heater. Do not pierce or burn piping. Be aware that R290 may not contain an odor. Compliance with national gas regulations
shall be observed.
Compared to common refrigerants, R290 is a nonpolluting natural refrigerant
with no harm to the ozonosphere greenhouse. R290 has got very good
thermodynamic features which lead to high energy efficiency.

1.1 Introduction
Your Ecogenica 215 and 290 FR models are ground-breaking integral quick connect, direct heat transfer, Heat Pump Heating
technology. That means Ecogenica is more reliable and energy efficient. And the innovation in our split condenser tank design
is at the forefront of the industry right now. Designed and developed in Australia for Australian conditions by our design team
who have been designing the most energy efficient Heat Pumps for more than 30 years.
Circulation pumps, and troublesome heat exchangers are not used, so fewer moving parts and no heat exchanger maintenance
is required, making this a more reliable and resilient design compared to other heat pump water heater available. Your very
high energy efficiency means superior energy saving compared to other Heat Pump Water Heaters. The Coefficient Of
Performance (COP) of 4.8 means that for every 1 kW of power used from the grid (or from your solar power system) the Heat
Pump put into the water 4.8 kW of effective power, by extracting heat energy from air. The Ecogenica 215 and 290 models
are fully dedicated Heat Pumps and use the most advanced Reverse Cycle Heating Technology to heat the water instead of the
air. The large surface area incorporated into the heat pump design means the Ecogenica does not need a heat element and will
continue to extract heat from the air even in freezing weather.

1.2 How does it work?
The secret to this physical process is the use of the naturally very cold R290a natural gas, which absorbs heat energy as it
passes through the large heat pump fin coil. As the gas passes through the fin coil heat from the air turns the cold low pressure
R290 vapor into a high-pressure gas, which then passes through a high efficiency rotary compressor, becoming super-heated.
The Super-heated gas passes through a heat jacket which is wrapped around the water cylinder and once the gas loses heat
energy to the water it turns back into a cold vapor and the cycle continues until the water is piping hot. You can expect the
tank to heat up between 1 and 4 hours, wind, rain, snow, and summer.
The compressor compresses the gas, just like a bicycle pump (if you put your finger on it), and like the bicycle pump the gas get
hot. The hot high-pressure gas then passes through the Micro-Channel condenser, which is located on the steal water heater.
The Micro Channel Jacket heats the cylinder like an element heats a vitreous enamel frying pan. The Micro Channel Condenser
Jacket is on the skin of the steel water cylinder under an inch of highly insulating foam, so the heat has nowhere to go except
into the water. Best of all this means the jacket never encounters the water, and the direct heating process is more reliable
and efficient than other heating technologies.
1.3 Natural Refrigerant
Ecogenica is at the forefront of Natural Refrigeration use, for a cleaner environment. Refrigeration mechanics are not required during
installation, as the heat pump uses natural gas found commonly in the environment. R290a is (LPG) propane and as only 500 grams of
propane is in the sealed system the heat pump contains just a fraction of that contained in a typical LPG BBQ bottle. To realize the
function of the heat pump unit, a special refrigerant circulates in the system. The used refrigerant is R290, which is specially developed
for Heat Pump use. The refrigerant is flammable and odorless. Furthermore, it can lead to explosions under certain conditions. But the
flammability of the R290 natural refrigerant is very low and it can be ignited only by fire. Technicians must always turn on a
combustible gas detector when entering the service area and make sure equipment power cords are unplugged or disconnected safely,
as sparks from unplugging, or power disconnects could ignite flammable refrigerants. Service must also be performed in a well-
ventilated area, especially if the refrigerant system is being accessed.

The following safety warnings are very important, always read and obey all safety signs:
warning
•Operation without water in the water tank may cause the water heater to enter a protection state, which
may damage components in severe cases.
•This Heat Pump must be effectively grounded. RCD circuit breaker must be installed. Do not remove, cover, or damage
any permanent instructions or labels from the exterior or interior of the unit panel.
•Only qualified personnel should install in accordance with local and national regulations and this guide. Improper installation
may cause water leakage, electric shock, or fire alarm.
•All electrical connections must comply with the requirements of the local power company, the local power company, and
this guide. Do not use a rated fuse, otherwise it may malfunction and cause electrical fire.
•Do not insert fingers, rods or other objects into the air inlet or outlet. The fan is rotating at high
speed, which may cause injury. Do not use flammable sprays, such as hairspray or paint, near the
machine to avoid fire.
•Disposal: Do not dispose of electrical appliances as unsorted municipal waste, A separate collection
facility should be used. Contact your local government to find out Information about the collection
system. If electrical appliances are disposed of at landfills or dump sites, hazardous substances can seep into groundwater
and cause health problems question.
•The unit must be fixed firmly, otherwise noise and vibration may be generated.
•Make sure there are no obstacles around the device. In places with strong wind (such as seaside
areas), the unit should be installed in a windproof place.
•The PTR valve is operated every 6 months to ensure that the valve does not have any restrictions.
•And it should be well insulated to prevent the water in the pipe from freezing in cold weather.
cautious
•The ground electrode must be well grounded. Make sure all electrical sockets and plugs are dry and tightly connected.
•Before cleaning the Heat Pump, be sure to stop operation and isolate the unit (i.e., turn off the isolating switch or
circuit breaker). Otherwise, electric shock and injury may occur.
•Water temperature over 50 degrees Celsius will cause severe burns and even death.
Children, the disabled and the elderly are at the highest risk of burns. In the bath or
feel the water temperature with your hands before showering to avoid burns.
•Do not operate the machine with wet hands to avoid electric shock.
•A one-way check valve and a suitable isolation valve must be installed on the water inlet side.
•It is normal for the one-way safety valve to release some water during operation. However, if there is a large amount of
water, please contact our service team. Arrange drainpipes to ensure efficient drainage. Improper drainage can cause water
damage to surrounding areas such as buildings, furniture etc.
•Except for repair and maintenance purposes, do not turn off the power, especially in cold weather, as it may freeze the

•Prior to beginning work on, safety checks are necessary to ensure that the installation complies with relevant Australia
Plumbing Codes.
•The area shall be checked with an appropriate refrigerant detector prior to and during work, to ensure the technician is
aware of potentially toxic or flammable atmospheres.
cautious
The ambient air temperature must also be considered, the heat pump will not operate efficiently in temperature below
5 degrees, so day time operation should be considered and settings on the timer should be selected to provide adequate
operation to heat the water. If it is installed in closed spaces such as garages and basements, there must be unrestricted
air flow (such as installing a strong exhaust fan) to prevent freezing. Installing this unit in any of the following locations
may cause malfunction (consult your representative before purchasing):
oSeaside areas or places with salt in the air.
oHot spring areas with corrosive gases (e.g., sulfides).
oFactories with large voltage fluctuations.
oIn a cabin without a large enough exhaust system.
oPlaces exposed to direct sunlight or other sources of high heat should be avoided and protection from direct
sunlight (i.e. awnings should be considered).
oAreas with strong electromagnetic fields.
oAreas where flammable gases or materials are present.
oAreas where acidic or alkaline gases are present.

1. Installers need to firstly put the tank and condenser in place. The installer needs to work out the best layout strategy for the
pipe and consider all site issues before lowering the condenser pipes.
2. Place the device on a flat, firm surface capable of bearing 3 times the weight of the
device.
3. Locate the Heat Pump (Evaporator) within 2m from the Condenser Tank.
4. If there is no special drainage pipe (sink), be sure to ensure that the condensed water
flowing on the ground can be drained smoothly to avoid water pooling around the heat
pump. As condensate will otherwise drip from the appliance onto the floor if the
drainpipe is not added.
5. Please do not pile up obstacles onto the Heat Pump, as they may affect the smooth air
circulation (Should avoid the windward direction).
6. The outdoor unit (Heat Pump) is installed with a 25mm high rubber shockproof, and it
is firmly fixed with studs to avoid noise when the machine is running.
4-3 Water tank installation position
1. The water storage tank must be placed upright on ground, with a 10cm foot pad under it.
2. The installation site has a solid foundation and must be able to withstand a weight of more than 500kg. The tank should not
be hung on the wall.
3. If the water storage tank is installed outdoors, in tropical climates, subject to server weather, please bolt firmly to protect
against typhoon type weather.
4. Never install the wall bracket mounting support on the external walls of living areas, or bedrooms, as this may cause
vibration type noise. Install the wall mounting support on a garage wall, for example.

4-5 Connecting the couplings:
The EG Series comes standard with pre-charged 2-meter refrigeration lines for ease of
installation and to prevent leaks.
Procedure for connection of the condenser pipe to tank:
1. Remove the packaging and carefully lower the refrigeration lines towards the heat
pump. Connect the pre-charged refrigeration pipes using the (3/8" to l/4') quick
connect adapter supplied with the unit (in the quickie kit)
2. Guide the refrigeration line onto the female refrigeration quick connect adapter and
prepare to screw the male coupling to the female coupling.
3. When connecting the water tank, please check whether the sealing nut of the water
tank has fallen off, otherwise, use high-pressure nitrogen to clean the fluorine system
channel.
4. Once pressure is applied to the spanner the single use, one-shot coupling is folded back into the coupling, providing a high
flow path and low pressure drop for the refrigeration charge in the condenser pipe (located on the water tank) to combine
with the heat pump charge.
5. The couplings are connected and the refrigeration charge in the condenser pipe is released into the heat pump and the fully
charged heat pump is ready for plumbing connections.

4-6 Custom installations
If any customization is required, for example the pipes are to run under ground, through wall cavities, or walls, or to a heat pump on a
roof, or bracket located above the tank; then a refrigeration mechanic should be arranged to complete the tank and heat pump
connection, to the relevant Australian Standard.
Eco Alliance must also be notified, and approval must be secured from the Service Managers.
Extension pieces can be purchased, and this will enable an installer to extend the pre-charged connection by up to 5 meters.
If extension pieces are purchased, because the tank and heat pump need to be further apart than the standard 2-meter condenser
pipe will permit, these extensions must be purchased in advance. Installers must contact Eco Alliance to secure approval for any
customized installation layouts
4-7 Electrical connections

5-5 Refrigeration Service Guide
•All service work should be conducted only after approval from Eco Alliance has been secured and service and repair
technicians must be aware of Eco Alliance repair and service procedures.
•In case of a refrigerant leak all service and repair work must be completed in accordance with the AS/NZS 1596:2002
Australian/New Zealand Standard™The storage and handling of LP standards and all other relevant Australian Standards.
•No person carrying out work in relation to a refrigerating system which involves exposing any pipe work shall use any
sources of ignition in such a manner that it may lead to the risk of fire or explosion.
•It’s recommended that service agents contact Eco Alliance, to gain approval for the heat pump to be disconnected and
returned to Eco Alliance; instead of conducting refrigeration and electrical works on components and circuits contained
withing the Heat Pump.
•If in a commercial or industrial setting, then all maintenance staff and others working in the local area shall be instructed in
the nature of the work being carried out. Work in confined spaces shall be avoided.
•It is recommended good practice that the R290 Natural gas systems are not recovered. As they are flammable caution
must be taken to ensure sparks and open flame is not close to the service site.
•All refrigerants are if not R290 must be recovered safely. Prior to the task being carried out, ensure that:
1. Recovered refrigerantshall not be charged into anotherrefrigeratingsystem unlessit has been cleaned and checked.
2. Equipment shall be labelled stating that it has been de-commissionedand emptied of refrigerant.
3. The label shall be dated and signed
4. Ensure that there are labels on the equipment stating the equipment contains
•Ensure that the leak detection equipment being used is suitable for use with all applicable refrigerants, i.e., non-
sparking, adequately sealed or intrinsically safe.
•Recovering or purging the system must comply with all relevant Australian Codes. During repairs to sealed
components, all electrical supplies shall be disconnected from the equipment being worked upon prior to any
removal of sealed covers, etc.
•Ensure that the detector is not a potential source of ignition and is suitable for the refrigerant used. Leak
detection equipment shall be calibrated to the appropriate percentage of gas. Electronic leak detectors may be
used.
•If a leak is suspected, all naked flames shall be removed/extinguished. If a leakage of refrigerant is found which
requires brazing, all the refrigerants shall be recovered or removed from the system.
•When breaking into the refrigerant circuit to make repairs –or for any other purpose –conventional procedures
shall be used, for flammable refrigerants, it is important that best practice is followed since flammability is a
consideration.
•If recovery equipment is used ensure it is in good working order with a set of instructions concerning the
equipment that is at hand and shall be suitable for the recovery of flammable refrigerants.
•Check that it has been properly maintained and that any associated electrical components are sealed to prevent
ignition, in the event of a refrigerant release. Consult manufacturer if in doubt.
•If compressors or compressor oils are to be removed, ensure that they have been evacuated to an acceptable
level to make certain that flammable refrigerant does not remain within the lubricant. The evacuation process
shall be carried out prior to returning the compressor to the suppliers. When oil is drained from a system, it
shall be carried out safely.

5-6 Machine running dynamics
There are different heating times at different ambient temperatures.
Typically, lower ambient temperatures result in longer run times.
COP
Changes in ambient temperature and heating capacity Changes in ambient temperature and energy efficiency ratio
Note: The above data is measured in the laboratory to simulate the ambient temperature and humidity. If it is different
from the actual ambient temperature and humidity, this data is for reference only.
5-7 Protection method
When the self-protection mode is activated, the system will stop and start self-checking. Once the error is resolved, the
unit will restart. When the self-protection mode is activated, the error code will be displayed on the screen until the error
is resolved.
•The device can enter self-protection mode under various conditions, including but not limited to:
oBlocked air inlet or outlet.
oThe evaporator is covered with too much dust.
oThe unit receives incorrect power (over the 220-240v range)
5-8 Natural Refrigerant addition
The working medium pipe equipped with the main engine is the base length. When the length exceeds the base
standard length, the refrigerant must be added strictly according to the length of the working medium pipe.
Additional refrigerant is required. Please follow the table below, adding will affect the performance of the unit
Refrigerant addition
record
0.015kg/m×（L-base length）
Note: L is the length of the double-pass working fluid tube, in mm. After adding, please
record the final charging amount and keep it properly for subsequent maintenance.
