Do not puncture the water heater casing, smoke, or
activate sparking of any description within 1.5 meters of
this water heater. R290 may not contain an odour.
Compliance with national gas
regulations should be observed.
This water heater contains flammable
propane refrigeration in a sealed closed
refrigeration circuit.
Under no circumstances should “home craft” type
modifications be attempted. To avoid an electric shock
do not operate the machine with wet hands. If the power
supply cord is damaged, it must be replaced by the
manufacturer, its service agent or similarly qualified
persons to avoid a hazard.
Before cleaning, be sure to stop operation and isolate the
unit (i.e. turn off the isolating switch or circuit breaker),
otherwise, electric shock or injury may occur.
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.
The unit must be fixed firmly, otherwise noise and
vibration may be generated. Ensure there are no
obstacles around the device.
The pressure release valve (PTR)
should be opened every 6 months
to ensure that the valve does not
have any restrictions. The drainpipe
should be well insulated.
It is normal for the (PTR) to release some water during
operation. However, if there is a large amount of water,
please contact our service team. Improper drainage can
cause water damage to surrounding areas such as
buildings, furniture, etc.
Once operational, do not turn this unit off, as you may
disrupt the self-cleaning cycle which is required to ensure
safe water quality.
Note, this unit is equipped with electrical safety
measures and for these safety measures to be effective
the unit must be connected to power, other than when
servicing.
If the hot water system is not in use for several weeks, a
quantity of hydrogen gas may accumulate in the water
heater. To dissipate the gas safely, please turn on the hot
water taps for several minutes to ensure that gas has
been properly removed from the water heater. As the air
escapes, sounds may occur which is normal.
Water pressure: Minimum 200 kPa, and the maximum
inlet water pressure should not
exceed 500 kPa, if it does, a pressure
reducing valve is to be installed. See
installation instruction. A one-way
check valve and a suitable isolation
valve must be installed on the water
inlet side.
Water temperature over 50 degrees
Celsius will cause severe burns and
even death.

System Maintenance
Routine Inspection and Maintenance Guidelines
Please inspect the unit regularly for any visible signs of
damage. If any damage is detected, contact our
maintenance team immediately for assistance.
In regions where temperatures fall below 0°C, and if the
system will be inactive for an extended period, it is
essential to drain all water from the tank. This will prevent
potential ice formation inside the cylinder, which can
cause serious damage.
Anode Maintenance
Your water heater is equipped with a sacrificial anode to
protect the cylinder from corrosion. Over time, this anode
will wear out. We recommend replacing the anode during
your five-year service interval—or sooner if you reside in
an area with poor water quality.
Technician Safety and Repair Protocols
All repair work must be conducted under controlled
procedures to minimize risks associated with flammable
gases or vapors during operation.
Technicians and maintenance personnel must be fully
aware of the repair requirements and the working
environment. Avoid conducting work in confined or
sealed spaces. The repair area should be properly
isolated and free from combustible materials to maintain
a safe working condition. Ensure that all technical staff
are aware of the potential for refrigerant gas leaks.
Evaporator Maintenance and Safety Notice
The efficiency of the heat pump is directly affected by the
cleanliness of the evaporator. Dust, mud, or other debris on
the evaporator surface can block airflow, reducing the
effectiveness of heat exchange with the surrounding air. This
results in diminished heating efficiency and increased strain
on the unit.
To maintain optimal performance, customers must ensure
the heat pump remains clean and free from obstructions at
all times.
Important Safety Warning:
**DO NOT USE FLAMMABLE CLEANING PRODUCTS** to
clean your heat pump.
If you notice a buildup of grime or debris on the evaporator,
please **do not attempt to clean it yourself**. Contact
**ECONOVA** to arrange a professional maintenance visit.
Our trained technicians will ensure safe and proper cleaning
to protect your system and uphold warranty conditions.
DRAINING THE TANK
If the tank is to be replaced, ensure the site is appropriate for
safe drainage. Draining can be performed by connecting a
hose to the cold water inlet and running it to a suitable drain
point. To prevent the formation of a partial vacuum during
draining, it is necessary to disconnect the hot water outlet or
open the Pressure and Temperature Relief (PTR) valve.
Ensure that the drain line is positioned to safely discharge
water away from the operator while the valve is open. All
procedures must comply with *AS/NZS 3500.4:2021, Section
5.11*.
REFRIGERATION REPAIRS
All refrigeration leak detection must be performed using
equipment certified for R290 (flammable refrigerant). The leak
detector must be suitable for use with flammable gases and
must not generate sparks.
Prior to beginning work and throughout the process, use an
appropriate detector to check for refrigerant leaks. Only trained
and qualified personnel should carry out any refrigerant
handling or repair tasks.
WARNING – HOT WATER RISK
This appliance may deliver water at high temperatures. Always
refer to the *Plumbing Code of Australia (PCA)*, local
regulations, and the installation instructions to determine
whether additional delivery temperature control is required.
Failure to do so may result in scalding or other safety hazards.
PRESSURE & TEMPERATURE RELIEF (PTR) VALVE
MAINTENANCE
To prevent excessive pressure buildup within the water tank—
which may lead to tank deformation or reduce its service life—
the Pressure and Temperature Relief (PTR) valve must be
maintained in working order.
Locate the PTR valve on the unit. Carefully lift the lever to
manually activate the valve, allowing a small amount of water to
discharge. This process confirms that the valve is functioning
correctly by relieving internal tank pressure as intended.
If water flows freely, the valve is operational. If water does not
discharge or the valve appears stuck or blocked, it may be faulty
and must be replaced immediately.
Homeowner Responsibility
It is strongly recommended that homeowners perform regular
checks on the PTR valve—ideally every six months—as outlined
in AS/NZS 3500.4. Routine activation of the valve helps prevent
mineral build-up and ensures the system remains compliant and
safe.
Failure of the PTR valve to operate correctly can result in
uncontrolled internal pressure, posing significant risk to both the
system and property.
If the valve is not functioning or requires replacement, please
contact your licensed plumber or our Ecogenica service team for
assistance. Only licensed tradespeople should perform
replacements or adjustments to the PTR valve.

2.Installation Safety
PTR MAINTENANCE
Periodic operation of the valve is recommended to ensure smooth water flow. If the
water does not flow freely, change valve.
To avoid the expansion and deformation of the water tank due to excessive pressure,
the service life of the water tank will be affected.
I. Find the position of the valve.
II. Carefully release the valve with the lever to release some water from the tank.
III. Note: Please use the water discharged from the container to avoid damage to other items.
IV. If the water is flowing, the valve is still in proper working order.
V. If the water does not flow freely, the valve is out of function and needs to be replaced.
VI. If the valve needs to be replaced, please contact your plumber or our service team for further assistance.
CHECK
Please check the machine regularly for any damage, if there is obvious damage, please contact our maintenance team.
In some cold areas (below zero degrees Celsius), if the system stops working for a long time, the water in the water
tank should be released before activating the heat pump, to ensure the water is not freezing.
Failure to do so may cause the machine to malfunction and, in severe cases, damage.
If water does not release from your P&T valve consult your plumber and ECONOVA®.
System Maintenance
CAUTION: WARRANTY REQUIREMENTS FOR WATER SUPPLY (CHLORIDE AND PH)
Heat pump units and hot water tank units with a Ph value less than 6.0 are not guaranteed. The water supply to
rainwater storage tanks within urban agglomerations can be corrosive due to the dissolution of atmospheric pollutants.
Water with a pH value of less than 6.0 can be treated to increase the pH value, so it is recommended to analyze the
quality of tap water before connecting to this type of water supply system.

DISPOSAL
Your heat pump contains electrical com ponents. If
electrical appliances are disposed of in landfills or
dump sites, hazardous substances can seep into
groundwater and cause health problems. Please note,
the tank and heat pump must have the R290 natural gas
released, or removed, before the units are sent to metal
recycling, or to your local council appliance recycling
centre. Note, ECONOVA® maintain a metal re-cycling
service.
PLUMBING
Care must be taken to ensure the system is installed in
accordance with AS/NZS 2712 and to AS/NZS
60335.2.40:2019 - with household and similar electrical
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 line of the water heater to prevent
the water temperature from exceeding a pre-set safety
upper limit.
The installation must conform with the Plumbing Code
of Australia (PCA), regulations of the local authority, in
line with national building regulations and local
occupational health and safety regulations.
Only licensed professionals will issue a certificate of
compliance, certifying that the work in question meets
all relevant standards, and only licensed professionals
will take out craft insurance.
Ensure that the heat pump unit is installed in a
compliant and accessible location is crucial for
maintaining its warranty and ensuring efficient service.
Please refer to the installation guidelines in this manual
for detailed information on compliant installation
practices.
CUSTOM INSTALLATION
Please consult with ECONOVA® about internal
installations. If a safety tray is required to prevent
building damage, construction, installation and draining
of a safe tray must comply with AS/NZS 3500.4 and all
local codes and regulatory authority requirements.
CONDENSATION DRAIN
Plumbing must be well insulated. Lagging must be applied to pipes and valves for at least the first 500mm
in all directions, including PTR drainpipes. Customer should consider investing in best practice plumbing to
have external hot water pipework to the primary kitchen sink lagged. As every home is different pipework
plumbing insulation in the home is quoted separately.
All installations of ECONOVA® Heat Pump systems must comply with the AS3000 electrical standards. It is
the responsibility of the licensed electrician to ensure that all wiring, power supply connections, and
protective devices adhere to these regulations to guarantee safe and effective operation.
CIRCUIT BREAKER
The hot water pump power supply must be protected by a
separate RCBO on the main power switchboard, if the unit
has an electric element, and it must be rated to suit the
size of the components.
Models with electric booster elements MUST be installed
on their own dedicated circuit to avoid overloading and
ensure proper operation. Models without an element can
be installed on a shared circuit. However, care must be
taken by the licensed electrician to ensure that the shared
circuit is not overloaded.
The RCBO must be incorporated into the fixed wiring in
accordance with the wiring rules and regulations (AS/NZS
3000 -Australian wiring rules).
P&T VALUE DRAIN LINE
A drain line from a relief valve must comply with the
requirements of AS/NZS 3500.4. The outlet of a drain
line must be easily seen, and arranged so discharge
will not cause injury, damage, or nuisance. Drain some
of the water heater must be directed away from the
building, fall continuously, discharge water away from
the operator during the operation of the valve and PTR
drains must use copper piping.
GROUND CONNECTIONS
Proper ground connection is essential. The presence of
water in the piping and water heater does no t provide
sufficient conduction for a ground. Non-metallic
piping, dielectric unions, flexible connector s plumbing
etc, can cause the water heater to be electrically isolated
The heat pump must be installed on a flat dry surface. 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.

APPLIANCE OPERATION
In case of possible direct exposure to strong wind, face
the air outlet to the most protected area. The direct
incidence of strong wind in the outlet grille during long
periods may affect the performance of the heat pump
increasing the heating times and the frequency of
defrost cycles.
This water heater should not be installed in an area
with a corrosive atmosphere where chemicals or
flammable liquids are stored or where aerosol
propellants are released.
BOOST CONTROL
Some ECONOVA® models contain an electric element
(see Product Specifications) for Automatic boost
control, which will activate the heating element in
extreme usage or temperature circumstances. This
control is built into the PCB and is not controllable
from the control panel. Boost is automatic and does
not adjustment.
INLET-OUTLET CONNECTIONS
Installation of the water inlet or outlet pipes: The water
inlet and outlet thread are ¾ BSP (internal thread).
Pipes must be heat resistant, durable and UV resistant
(when doing outdoor installation). Installation of the
pipe for PTR valve: The specification of the valve
thread is ½ BSP (internal thread). Note: one way valve
must be installed at the inlet.
PRE-INSTALLATION
Ensure that there is enough space for installation and
future maintenance. Do not install the heat pump in an
area that is not easily accessible for maintenance and
repair work. This includes installations in confined
spaces, locations requiring special equipment to
access, or areas that pose a safety risk to our
technicians.
The air inlet and outlet should be free of obstacles and
strong winds.
The bottom surface should be flat and capable of
bearing the weight of the heat pump,
ensuring that no noise and/or vibration results
from poorly installed tank.
POWER REQUIREMENTS
Check the markings on the rating plate of the water heater
to be certain the available power supply corresponds to the
water heater requirements. The Heat Pump Water Heater
must be directly connected to a 230V-240VAC 50Hz mains
power supply.
The water heater Heat Pump must be installed on separate
individual circuits with a breaker switch installed directly at
the switchboard.
Fill the heat pump tank with water before starting the heat
pump for the first time.
SOLAR POWER
Some ECONOVA® models come with Wi-Fi; and all models
have timer activation to better align operation with Solar
Power production. Solar Power must be provided to the
inverter and switch board, as per local regulations and Solar
installation Standards. The timer ensures that the Heat
Pump operates between daylight hours, to align with Solar
Power production.
Solar Power is limited during rainy days, and in the
Winter Months, and hot water loads increase, so we
recommend that timer activations are not used during
these times. Note, the ECONOVA® heat pump will
mostly operate during the day in the Auto Mode if people
show in the morning.
SITE REQUIREMENTS
The running noise and the exhausted airflow should not
affect other people. Take care to consider the location of
bedrooms and noise sensitive areas.
Unsafe Installation location: Installation must comply with
safety standards and regulations. Including, and not limited
to, areas with inadequate ventilation, proximity to
hazardous materials, or installations that violate
manufacturer guidelines.
Do not install in areas with pH & chlorides outside the range
listed here (pH 6 to 10) & Chloride >200):
Installations indoors are not recommended,
and permission must be secured from
ECONOVA®.
Ensure the site is suitable for 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.
while
When installing the tank DO NOT use adhesives since
they are not considered to be a reliable fixing means.
15
Pre-Installation Safety Information
PIPING CONNECTIONS
The water inlet and outlet thread are 3/4 BSP (internal
thread). Pipes must be heat resistant, durable and UV
resistant (when doing outdoor installation). Installation of
the pipe for PTR valve: The valve thread specification is ½
BSP (internal thread). Note: non-return valve must be
installed at the inlet.
The temperature and pressure-relive valve must
beinstalled according to local code. Not doing so will
cause damage to the appliance and to other property.
The function of the temperature and pressure relief valve
once installed on this water heater is to discharge high
conditions. Therefore, it is strongly recommended thatt he
pipe work connected to the relief valve can withstand water
temperatures exceeding 99˚C. Failure to follow this
recommendation may result in a dangerous situation.
DIELECTRIC JOINT
The dielectric joint will basically avoid any physical contact
between the two metals, acting as an effective insulator
and prevent this attack. How quickly this, or it at all,
happens, depends a lot on the content of your water. It’s
pH, the dissolved minerals and the metals involved.
Never block or seal the outlet of the PTR
valve or its drain for any reason. The
warranty will be void if the relief vale or
other safety devices are tampered with or if
the installation is not in accordance with
this manual.
CONDENSATE DRAIN TUBES
This unit has an integrated condensation tray. The water
collected in the tray drains out of the tube. It is
important that a hose is attached to drain. Ensure the
heat pump is on a flat, firm surface capable of bearing
the weight of the device. 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.
All pipe work should be insulated with proper insulating
material (weatherproof and UV resistant if exposed) to
optimise energy efficiency.
To ensure the faultless operation, the unit must be
installed vertically without a significant tilt, minor tilts
should be in the direction of the condensate drain to
favor the condensates drainage.
Take care to consider the location of bedrooms and noise
sensitive areas. The running noise and the exhausted
airflow should not affect other people.
The inlet and outlet should be free of obstacles and strong
winds.
Installation must comply with safety standards and
regulations. Including, and not limited to, areas with
inadequate ventilation, proximity to hazardous materials,
or installations that violate manufacturer guidelines.
16
Different metals between plumbing and tank materials and
additionally the effect of hot water can cause the corrosion
of one of the metals (generally the one in the tank is the
metal attacked).
Installation
THERMAL EXPANSION TANK
The pressure rating of the relief valve
must not exceed 850kPa, the maximum
working pressure of the water heater as
marked on the rating plate! Proper
ground connection is essential!
TEMPERATURE MIXING DEVICE
The PCA (Plumbing Code of Australia), AS/NZS3500.4 ;
requires the installation of a temperature limiting devic e
between the water heater and the hot water outlets in a
bathroom or similar usage point to reduce the risk of
scalding.
The maximum temperature that can be delivere d is 50
degrees Celsius. Additionally, a certified plumber may
have the legal obligation to ensure the water heater
installation meets the hot water delivery requirements
listed in AS/NZS3500.4.
POWER SUPPLY AND ELECTRICAL INSTALLATION
REQUIREMENTS
EXPANSION CONTROL DEVICE
Thermal expansion is a natural process where heated
water increases its volume. When this water is stored in
a tank, this volume increase will in fact mean a pressure
is increased in the tank. This pressure increase
potentially can result in a dangerous situation if
Pressure Relief Valves are not releasing water
occasionally. Consequently, when the safety settings on
the relief valve are reached, the relief valve will operate
during the heating cycle. Please contact a licensed
professional, water supplier or plumbing inspector for
information about this subject.
A temperature and pressure relief valve are supplied
and must be installed in the tank port marked for this
purpose. No valve or accessory of any type should be
installed between the relief valve and the tank. Please
observe local codes for the correct installation of relief
valves.
The kW rating of the relief valve must be higher than
6kW to ensure that is always above the maximum
output power of the water heater when operating with
both electrical heated and heat pump and air at 40˚c.
The supplied PTR valve complies with this by having a
power capacity of 10kW.
Connect the outlet of the relief valve to a suitable open
drain so that the discharge water cannot contact any
electrical parts, persons or animals and to eliminate
any other possible risks. Always use a valve of the
same rated pressure and temperature as the PTR valve
supplied with the unit.
A saturation index greater than +0.4 or in corrosive
wate r areas where there is enough silica dissolved in
the wate r may require the installation of an expansion
control valve (ECV) in the cold-water line, being the
last valveinstalled prior to the water heater.
PTR VALVE
17
Installation
Before installation, verify that the available power supply
matches the specifications listed on the rating plate of
the heat pump water heater. The unit must be connected
to a 230–240V AC, 50Hz mains power supply.
The heat pump water heater must be installed on a
dedicated individual circuit protected by an RCBO
(Residual Current Breaker with Overload protection)
located at the main switchboard. An effective and
reliable earth connection is required for safe operation—
ensure the ground wire is securely connected to the
external grounding system.
All power wiring should be laid out neatly and securely,
avoiding splicing of wires wherever possible. Electrical
connections must comply with all relevant safety
regulations and wiring standards.
Important: The unit must only be powered on after the
tank has been completely filled with water.
Wi-Fi Setup:
To enable smart control, download the companion app
and pair your heat pump to your device following the
application instructions.
Solar and Off-Grid Use:
- In warmer months, the heat pump can be set to operate
between 10:00 AM and 5:00 PM using the timer function
for optimal use of solar power.
- During colder months, we recommend using Auto Mode
without a timer to ensure consistent hot water
availability.
- For off-grid installations, ensure the system is
connected to a UPS (Uninterruptible Power Supply) with
a 230–240V AC, 50Hz true sine wave output.
Circuit Protection:
To ensure uninterrupted operation, the hot water heat
pump must be protected by a dedicated RCBO rated
appropriately for the installed components. Do not
connect any other appliances—especially high-power
devices—to the same power supply circuit as the water
heater.
Installation
CLEARANCE REQUIREMENTS
To ensure proper operation and serviceability, the following minimum clearances must be maintained:
A minimum of 300 mm clearance must be provided on both sides of the heat pump, at the air inlet and outlet, to
allow for adequate airflow.
An overhead clearance of 300–400 mm must be maintained above the unit to allow for future access if servicing is
required.
Failure to maintain these clearances may impact system performance and access for maintenance.
