2.0 INSTALLATION INSTRUCTIONS
2.1 DELIVERY
• Hydrotherm heat pumps must be stored
and transported in a near vertical position at
all times with a tilt ratio of no more than 30°.
Transporting or storing the unit in a horizontal
position will void warranty.
• The system should always be transported in
it's packaging.
• The weight of the package system is
128kg (106kg unpacked). The system must be
handled by two people at all times
to avoid unnecessary strain and damaged.
• Please note the outer casing of the unit
is susceptible to denting and damage. Care
and consideration should be taken into account
when moving the unit as any marks
caused by inappropriate handling are not
deemed as defects and are not covered under
warranty.
2.2 BASE
• The unit should be installed on a concrete plinth or stable structure capable of sustaining weights in excess of
450kg. If a concrete base paver is being used, a minimum dimension of 600mm x 600mm is required.
Please ensure that all three feet are supported by the base being used otherwise warranties may be voided.
• Proper drainage should be observed for any overflow in accordance with AS/NZS 3500.2.
• When installed the Hydrotherm unit must be completely vertical and level as to ensure that condensate can be
properly drained. If the system is installed at a level with a tilt of more than 3 degrees, warranties may be voided.
• If installed under fixtures or home eves, there must be a minimum 300mm clearance between the top of the
unit, 600mm on the right hand side of the system (when facing unit) and 600mm on the left hand side of
the system (when facing system) (see section 2.3 AIR FLOW). The Hydrotherm must be installed a minimum of 100mm
off your home's wall so that the entire unit can be accessed during any servicing work as well as to prevent
circulation of cold air (see section 2.3 AIR FLOW). If the system cannot be properly serviced due to the system
being installed closer than 100mm off your home's wall, the owner will be liable for the associated
plumbing costs of draining and moving the system.
•The Hydrotherm should be installed so that the control interface is accessible to users and that there is clear
access to the electrical panel at the back of the system. Where incorrect installation has occurred warranties
may be void or additional charges may be required to ensure that the system is compliant.
All Hydrotherm heat pumps are designed for installation by a licensed plumber in accordance with
standards set out in AS/NZS 3500.2 “National Plumbing and Drainage Code Hot Water Supply
Systems - Acceptable Solutions”.

• The Hydrotherm range has been designed with the lowest possible running noise level (>49dB) to ensure
optimum comfort and minimum impact on living areas.
• All Hydrotherm customers are recommend to set the system onto ECON Mode to utilize the in-built
timer function. Setting the in-built timers to have the system run during the day is far more efficient and
will also limit any potential disturbances.
• Select a location that is removed from bedrooms if possible as the unit may function for a period of time during
the night.
2.5 NOISE CONSIDERATIONS
2.4 TARIFFS
Electricity companies across the states and territories of Australia have different usage rates, naming conventions
and even available tariffs. Generally these tariffs are:
oContinuous tariff - Tariff 11 (QLD) - 24 hours a day .
The Continuous tariff is what every household connected to the grid has as a minimum. If you would like to
utilize a Solar PV system to run your Hydrotherm system on, this is usually the only tariff available to do so.
oShoulder tariff - Tariff 33 (QLD) - Min. 16 hours a day .
The Shoulder tariff typically runs during the day and will turn off at night. The cost per kWh is cheaper
than a Continuous tariff. If your household has more than 4 people or are heavy users of hot water, we
recommend placing the Hydrotherm system on a Continuous tariff instead.
oOff Peak/Night time tariff - Tariff 31 (QLD) - Min. 8 hours a day
Hydrotherm strongly recommends not putting your system on an Off Peak tariff for the following reasons:
oHydrotherm heat pumps work up to 25% more efficiently during the daytime when ambient air
temperatures are at their highest. The cost of running the system is actually cheaper running on a Shoulder
tariff or Continuous tariff as the system will take considerably longer to heat on an Off Peak tariff.
oYou may run out of hot water. If your system needs to heat twice a day, it will unlikely be able to do some
on an Off Peak tariff.
oServicing cannot be done outside business hours (the only hours an Off Peak tariff has power). If the
system needs to be changed onto another tariff, the Hydrotherm owner will be liable for the associated
electrical costs.
If you would like further information regarding tariffs, we recommend speaking with your electrician and energy
service provider before your Hydrotherm is installed.
Note: When installing do not install less than 3 metres to a neighbour’s window or door other
than a garage door or shed.

4.0 PLUMBING INSTALLATION
PLUMBING CONNECTIONS
1. Cold Water Supply Outlet
• The cold water supply connection is a 3/4” female thread.
• The cold water supply should be connected to RP 3/4” socket.
• The cold water supply outlet can also act as a drainage point for emptying the system.
2. Hot Water Connections
• The hot water supply connection is a 3/4” female thread.
• The hot water supply should be connected to RP 3/4” socket.
•To ensure thermal efficiency all hot water lines and connections must be insulated with a minimum 13mm closed
cell insulation.
• All hot water supply parts must be constructed from copper. If using pipe of other material please refer to local
authorities for further instructions.
3. Condensate Drain
• The process of heat extraction from the atmosphere
through evaporator coils results in the production of water
in the form of condensation. More humid environments will
produce higher rates of condensation.
•To collect this water by-product a Condensate Tray is
located on top of the water storage tank. Overflow from
this tray runs out through the Condensate Drain.
• The condensate connection is a 3/4” female thread. A
RP 3/4” elbow socket is supplied with the system which
must be connected to the drain outlet. Drainage of
condensate from elbow to nearest storm water to be
done by the collection of condensate into an open dish
and drained via copper piping. If not drained properly,
the condensate line will attract termites as well produce
algae and moss growth.
• The Condensate line should be free of kinks and as the
water is gravity fed, should only be running down to
ensure the free flow of water.
Connecting any pipe directly to the condensate line without air gap will void warranties

IMPORTANT:
A discharge pipe connected to the pressure- relief device is to be installed in a continuously
downward direction and in a frost-free environment. Warning: Do no connect any pressure-relief
device to the vent pipe of this water heater. The water may drip from the discharge pipe of the
pressure-relief device. This pipe must be left open to the atmosphere. The pressure-relief device
is to be operated regularly to remove lime deposits and to verify that it is not blocked.
• The system is supplied with a loose Pressure & Temperature Relief (PTR) valve appropriate to the pressure
rating of the water heater tank. If the PTR valve is not present please contact your supplier. The valve rating is
700kPa.
• The supplied PTR valve must be installed at Point 4 in section 3.2 Dynamic Connection Dimensions and
Components under the socket marked "RELIEF VALVE".
• The PTR valve must be insulated with a minimum 13mm closed coupled insulation, to minimize heat lost.
• The relief valve must be installed so that the drain line is facing downwards at all times with the discharge
point remaining open to the atmosphere.
4. Pressure & Temperature Relief (PTR) valve
5.Tempering Valve
• This device is automatically programmed to produce hot water in excess of 50°C. As such in accordance with
AS/NZS3500 it is mandatory that a “Tempering Valve” is installed.
• We recommend a high performance or solar rated tempering valve is used to ensure a more accurate hot
water delivery temperature.
•Your old hot water system might not have had a tempering valve installed before and therefore you will notice
a change in the temperature of the hot water. This is normal and required under the new legislation. Should you
have any concerns, please contact your installer.
6. Expansion Control Valve
• The system is supplied with a loose Expansion Control Valve (ECV) appropriate to the pressure rating of the
water heater tank. If the ECV valve is not present please contact your supplier. The valve rating is 600kPa.
• Observe the local requirements with regards to the installation of an ECV (optional in most counsels).
• When installing an ECV, ensure that the connecting pipe has a diameter no greater than that of the safety
valve.
• Ensure the drain is sized to allow for water runoff, even in incidents where the safety valve has been fully
opened.
• The drain outlet must remain open to the atmosphere at all times and must not have a closing function.
8. Pressure reducing valve
• The maximum inlet pressure to the system must be no more than 500kPa. Should the system be subjected to
pressures above 500kPa all warranties will be void.
• A pressure reducing valve must be used in the direct cold water supply line feeding into the system.
• This water heater is supplied with a PTR valve rated at 700kPa and is designed for direct connection to mains
water supply with a pressure not exceeding this rating. Should main pressure fluctuate above this rating, a
pressure limiting device (AS1357) should be connected at Point 8 in section 3.2 Dynamic Connection Dimensions
and Components.
11

4.0 PLUMBING INSTALLATION
9. Non-return Valve
• It is recommended that a non-returning valve is installed directly into the cold water supply line feeding the
system. This will allow the hot water system to be isolated from the rest of the homes water supply, making
servicing, draining and replacing the unit easy.
• The non-return valve can be combined with a PRV valve to form a duo valve as shown in the above schematic.
Filling The System
• Once the Hydrotherm has been connected in accordance to section 3.0 and 4.0 of this handbook,
the tank can be filled and pressurized.
• Open the non-return valve on the cold water inlet to begin filling the system with water. At the
same time, ensure at least one hot water tap is open inside the property. While the system begins
filling with water you will hear air being expelled from the open hot water tap. This is called
"bleeding the system" and it ensures that no air pockets remain. Once water begins running out of
the hot water tap, the system is completely bled and you can then turn the tap off.
• Always ensure that the tank is completely full before connecting and turning on electricity supply.
• When the system has been left running, but no hot water has been used for an excessive period of
time, it is recommended that hot water tap is left running for several minutes to remove any potential
gases through the plumbing network. Please do not smoke or have naked flames present during this
time.
