Heat Pump System Theory:
(1) Using a small power input to drive the compressor, the power used is Q1.
(2) While the unit is running, the power that comes ambient air is Q2 (from the refrigerant
transformation).
(3) The energy that the water gets from the unit is Q3.
(4) According to the law of conservation of energy:
﹛Sum of input power = sum of output power Q1+Q2 = Q3
﹛In standard working conditions, the power that heat pump gets from the environment is about
3.2 times the power input, Q2 = 3.2 x Q1
so: Q3 = Q1+Q2 = Q1+3.2Q1= 4.2Q1
Which means you can get 4.2Q1 from heat pump if you spend Q1 energy. Which means the
energy that you can get from heat pump after using 1 kW of electricity is equal to the energy that
you get from electrical element heater after using 4.2 kW of electricity. This makes the hot water
heat pump is one of the most energy efficient heating equipment available on the market today..

3.Operation
3 min safety protect
If the unit stops and you re start the unit or turn it on manually, the unit will not start to run
again for approx 3 minutes. This is a protection feature to safe guard the compressor.
In low ambient conditions the heating output decreases. See page __ for further
information.
Heating capacity
In order to use the unit correctly, please run the unit at environment temperature -7→-43→.
The unit includes sophisticated electronic devices, prohibited to use water from lake, untreated
river water and groundwater!
Working conditions
Defrosting
In heating mode the unit will defrost automatically, maximizing the heating efficiency (Lasting 2 -
10 minutes).
The fan motor will stop running whilst the unit is defrosting.
Overheating protection
When the water temperature reaches 75deg C, the power of the unit will be cut and must be
manually reset. See page __ for more information.
Water pressure protectiontemperature or
A P&T valve MUST be installed in the tank. When the tank pressure reaches 0.85MPa or
when the tank temperature reaches 93deg C, the P&T valve will open automatically so as
to reduce the pressure or temperature decrease.

4.2 Freight and Transportation
As a rule, the unit should be stored and/or transported in its shipping container in an upright
position and without water charge. For transport over short distances, and provided due care
is exercised, an inclination angle of up to 30 degrees is permitted. During transport and
storage, ambient temperatures of - 10 to +60deg C are permissible.
4.2.1 Transport using a forklift
When transported by a fork lift, the unit must remain mounted on the pallet. The lifting speed
should be kept to a minimum. Due to its top-heaviness, the unit must be secured against
tipping over. To prevent any damage or injury, the unit must be placed on a level surface.
4.2.2 Manual transport
For the manual transport, the wooden pallet can be used for bottom part.
Using ropes or carrying straps, a second or third handling configuration is possible. With this
type of handling, care must be taken that the maximum permissible inclination angle of 60
degrees is not exceeded. If transport in an inclined position cannot be avoided, the unit should
be left to rest at least one hour after it has been moved into final position before operation.
CAUTION! High center of gravity, Place on a level surface!

Indoor Installation Recommendations
To cool the room using the Evoheat 270.
Heat pumps operate most efficienctly with warmer air temperatures, and the outlet air from
the unit will be colder than the inlet air. Therefore it is advisable to install the unit so it
recieves the warmest air temperatures possible and the cold air is not able to recirculate
back into the unit.
The unit may be able to be installed in an unventilated room exceeding 25m3 in volume.
Venting of cold air is always advisable to prevent the air temperature dropping and lowering the
efficiency of the unit.
Think of the unit as a 3kW airconditioner for the effect it will have on a closed room.
Install the unit so the outlet from the heat pump is blowing INTO the room. The room MUST
have some form of air outlet otherwise the performance of the unit will suffer significantly
To maintain the room at normal temps using the Evoheat 270.
Install the unit so the outlet from the heat pump is blowing OUTSIDE the room. The room
MUST have some form of air inlet otherwise the performance of the unit will suffer
significantly
PLEASE CONTACT EVOHEAT FOR TECHNICAL
ADVICE IF UNSURE
1. This unit must be installed, operated and maintained in good order and in accordance with
these instructions.
2. If water supply exceeds rated pressure a pressure reducing valve is to be fitted.
3. Water may discharge from the drain pipe and this must be left open to atmosphere
4. The pressure relief valve must be operated at least every 6 months to ensure correct
operation. The drain pipe from this valve should not allow water to collect in pipework.
5. Facilities for draining and filling the unit must be provided for maintenance. Drain points
must be at the lowest point of the system.
6. Check before installation that your water pressure is within required limits. Use a filter and
pressure relief valve on the inlet as required.A water softening device will also be required in
hard water areas.
7. This heat pump must be installed by a licenced contractor. Do not attempt to install yourself
if you are not qualified.The Evoheat 270 must be installed to conform to all relevantAustralian
Standards and Industry Codes including but not limited to:
Electrical and Electrical Safety
Plumbing and Hot Water Storage
Heat Pump Installation and Operation
Installation must also comply with any local, sate or federal codes at the installation site.
Failure to comply can void your warranty, damage your unit and cause possible injury or death.
Plumbing must comply withAS/NZS3500.4

Mode Descriptions
Eco Mode
This mode does not use the Hydropower element boost and is the most economical mode.
Start with this mode initially and if you encounter water which is cold or warm switch to
Intelligent mode.
Intelligent Mode
This mode analyses ambient temperature at 10am each day and decides the best operating
mode from Eco or Heating.
Heating Mode
This mode uses the heat pump as the main heat source. The Hydroboost starts after a 40min
delay to give high recovery rates. Use this mode if you have very high hot water usage. The
Hydroboost start times and temps are all fully customisable.
You can also manually switch on the Hydroboost element at any time by pressing the
Hydroboost button on the controller.
Setting the timer to allow the unit to run for longer periods will also help to ensure you never
run out of hot water.
