4. Installation
4.1 System Installation
The schematic diagram is for reference
only. Check the water inlet/outlet label on
the heat pump while plumbing the unit.
EvoHeat only provide the main EvoHeat
unit and EvoHeat accessories; other items
in the illustration above should be provided
by the user or the installer.
EVOHEAT ACCESSORIES –DO NOT THROW AWAY
All EvoHeat units are provided with rubber feet, controller and leads for the controllerdo not throw them away as
they are required as part of the installation.
CHECK HEATER CONDITION ON ARRIVAL
Check the heater packaging upon delivery for any obvious signs of damage. Inform your supplier IMMEDIATELY if
there is any evidence of rough handling. When the heater has been removed from the packaging check the refrigerant
gauge on the front panel of the unit. The gauge should be showing a pressure of approx 10-20 on the outside red
band any less than this figure means there may be a leak in the refrigerant system, and you should immediately
contact your EvoHeat Dealer.
General installation information disclaimer: Install your EVOHEAT heat pump in accordance with the procedures in the
product manual. Always check that your installation will comply with local building and council regulations.
IMPORTANT: EvoHeat heat pumps MUST be connected by a licensed electrician. Under no circumstances
should an unlicensed person attempt to install or repair an EvoHeat heat pump themselves. Heater electrical
installation undertaken by an unlicensed installer will void the warranty. Correct installation is required to ensure safe
and efficient operation of your pool heater.
Before installation it is very important to ensure 5 variables are carefully checked to allow the unit to operate correctly:
Location
Clearances & Airflow
Adequate Water Flow & Plumbing
Correct Electrical Connection & Supply

4.2 Location of Installation
Evo recommend the heat pump should ONLY be installed in an outdoor location with appropriate ventilation. Installing
the heater indoors without adequate ventilation, or in a poorly ventilated enclosed space, will result in very poor
performance and can, in extreme cases, damage the heater.
Ensure the heater is installed in a well-ventilated area with plenty of fresh air. Evo recommend the heat pump should
ONLY be installed in a location with appropriate ventilation.
If installing the heater on an existing pump/filtration system, the heater must be installed AFTER the filter and
BEFORE the chlorinator/sanitizer.
The Evo unit should be
installed:

- On a flat level surface as close as possible to the pool
A rough estimate of heat loss over a 30m pipe run can be as high as 600 Watts per hour per 5 degrees of temperature
difference between the air/ground and the pool water. These losses need to be taken into account over long distances
and piping may need to be insulated to reduce heat leakage.
Make sure the heat pump is not located where large amounts of water may run-off from a roof into the unit. Sharp
sloping roofs without gutters will allow excessive amounts of rain water mixed with debris from the roof to be forced
through the unit. A water deflector may be needed to protect the heat pump.
If a suitable outdoor location is unavailable please contact EvoHeat for specialist technical advice.
4.3 Airflow Clearances
The heat pump unit needs continuous fresh air whilst
running. The heater draws up to 47000 m3/h ambient air
through the sides and discharges through the top fan cowl.
Installing the heater indoors or in an enclosed space will
result in very poor performance and can in extreme cases
damage the heater. Ensure the heater is installed in a well-
ventilated area with plenty of fresh air, a minimum gap
between walls/fences etc of:
1000mm on the sides
800mm on the ends
and a 3500mm overhead clearance.
When units of a similar height are placed side by side,
EvoHeat recommend a 1500mm clearance between units.
Leave sufficient space for unobstructed airflow into and out
of the heater. Do not locate the heater in an enclosed area,
or the discharged cold air will recirculate into the unit and
consequently lower the heating efficiency as well as possible icing up.
If you do not have a location with these suggested clearances, please contact our EvoHeat Tech Support Specialist to
discuss appropriate installation locations.
Fan discharge distance can be reduced by adding a Plenum to alter the air flow direction. Contact EvoHeat
or a HVAC specialist for further advice. If you do not have a location with these suggested clearances,
please contact our EvoHeat Tech Support Specialist to discuss appropriate installation locations.

4.4 Adequate Water Flow
All EVOHEAT heat pumps have a factory preset internal water flow switch. If there is insufficient water flow the heater
will not operate.
It is CRITICAL that there is sufficient water flow to the unit. Incorrect water flow can cause a loss of efficiency and
possible damage to the unit. Optimal water flow rates are listed in the EvoHeat manual. It is imperative that water flow
is kept as close as possible to these flow rates. Correct water flow not only offers optimal heater performance, but may
also prevent possible damage to your heater.
Before connecting the heater to the plumbing, all piping must be thoroughly flushed to ensure no debris can enter the
heater. Failure to remove pipe debris can jam or damage the flow switch and may cause damage to the heater. When
cleaning the pool it is advisable to turn off your heater as restricted water flow may cause the heater to shut down and
indicate low water flow fault (E03 error) or high pressure fault (E01 Error).
IMPORTANT: A Variable speed pump or bypass valve and plumbing MUST be fitted to allow water flow to be
adjusted through the heater. Do not direct connect a water pump with higher flow than required to the heat
pump.
4.5 Rubber Feet
All EvoHeat units are provided with rubber feet which EvoHeat highly recommend being installed. The rubber feet help
reduce vibration of the unit and help provide a space below the heat pump to install the drainage barbs.
4.6 Drainage & Condensation
Whilst the heater is operating, water in the air condenses on the fins of the
evaporator. During times of high humidity, the condensate may be several litres per
hour. This may give the impression that the heater is leaking, however this is a
normal function of heat pumps. The heat pump can also automatically activate the
reverse cycle defrost feature when required which increases condensation
produced.
Ensure CS series heat pumps are installed level so condensate is not allowed to
pool at one end of the condensate tray!
Ensure CS-GEN2 series units are installed level to evenly distribute condensate
through the two drainage holes on the condensate pan, located at either end of the
heat pump!
The condensate water captured will discharge from the heat pump through one end, typically where the heat pumps
Inlet/Outlet connections are located. The condensate discharges from the heat pump through a 32mm female
threaded connection. Ensure condensate is plumbed away from the heat pump to an appropriate location, ideally a
drain. Note: A 32mm Male threaded adapter is NOT supplied with the heat pump.
4.7 Plumbing
The heat pumps exclusive rated flow titanium heat exchanger requires no special plumbing arrangements except
bypass (please set the flow rate according to the nameplate). The water pressure drop is less than 10kPa at max.
Flow rate: Since there is no residual heat or flame Temperatures, the unit does not need copper heat sink piping.
PVC pipe can be run straight into the unit.
Location: Connect the unit in the pool pump discharge (return) line downstream of all filter and pool pumps, and
upstream of any chlorinators, ozonators or chemical pumps.
Standard models have slip glue fittings which accept 40 mm PVC pipe for connection to the pool or spa filtration
piping. By using a 50 NB to 40NB you can plumb 40NB.
Give serious consideration to adding a quick coupler fitting at the unit inlet and outlet to allow easy draining of unit for
winterizing and to provide easier access should servicing be required.

4.8 Electrical Connection
IMPORTANT: Always use a qualified Electrician to perform any electrical work. A licensed electrician must read the
information before connecting.
Ensure the power cable and circuit breaker are of a suitable size for the heater being installed. Also check that there is
adequate voltage and current available at the heater connection to run the unit.
Voltage range should be 220-230 volts for single phase, and 380-400 volts for 3 phase units. Voltage ranges outside
these parameters will cause heater damage and void your warranty.
1. Ensure power is disconnected during installation or service.
2. Always comply with the national and local electrical codes and standards.
3. Ensure electrical cable size is adequate for heater requirements at the installation location.
4. The heater must be equipped with a circuit breaker and isolation device.
5. Circuit breaker must be installed between the heater and the water circulation pump if the water pump is hard-
wired into the heater. Please note recommended circuit breaker sizes make no allowance for a water pump
hard wired into the heater.
6. The unit must be well earthed. Remove the front panel to access the electrical connection terminals of the
heater. The electrical wiring diagram is affixed to the inside of the front panel.
NOTE: Correct phase connection is important
with 3 phase heaters. If 2 lights are showing
on the 3 PHASE relay monitor this means the
EvoHeat heat pump has been wired correctly (one
orange light and one green light). If only one light is
showing, the phases are out of rotation and need to be
rotated to get the correct phase rotation.
4.9 Initial Start-up
Note: in order for the unit to heat the pool or spa, the filter pump must be running to circulate water through the heat
exchanger.
After installation is completed, follow the steps below:
1. Turn on your filter pump. Check for water leaks and verify flow to and from the pool.
2. Turn on the electrical power supply to the unit, then press the key ON/OFF of wire controller, it should start
after several seconds.
3. After running a few minutes make sure the air leaving the top of the unit is cooler (between 5-10 ℃)
4. With the unit operating turn the filter pump off. The unit should also turn off automatically.
5. Allow the unit and pool pump to run 24 hours per day until desired pool water temperature is reached. (Note:
this may take up to several days depending on the initial water temperature and the size and location of the
pool). When the water-in temperature reaches the set temperature the unit will shut off. The unit will now
automatically restart (as long as your pool pump is running) when the pool temperature drops more than 1℃
below the set temperature.
TIME DELAY
The unit is equipped with a 3-minute built-in solid-state restart delay included to protect control circuit components and
to eliminate restart cycling and contactor chatter. This time delay will automatically restart the unit approximately 3
minutes after each control circuit interruption. Even a brief power interruption will activate the solid state 3-minute
restart delay and prevent the unit from starting until the 5-minute countdown is completed. Power interruptions during
the delay period will have no effect on the 3-minute countdown.

6. Troubleshooting
HEAT PUMP NOT WORKING? CHECK THE FOLLOWING:
IS THE SCREEN OF CONTROL PANEL LIT?
If not, make sure the electrical wires and cables are correctly
connected and the power is on. Ensure any circuit breaker
devices are set to the ON position and press the ON button on
your controller. Check your controller cable is plugged in and
is not damaged. If the unit has been shut off or the power has
been interrupted the heater will not restart for a 5-minute
period to protect the compressor. Wait 5 minutes before
attempting a restart.
IS THERE ENOUGH WATER FLOW?
If the screen displays a water flow related error check the
water flow. Is the water pump in operation and the system free
of debris that may cause a blockage? Disconnect pool
cleaners to ensure proper water flow.
DOES YOUR HEAT PUMP HAVE AN ERROR
MESSAGE ON THE SCREEN?
If yes, refer to the error code table 19.
IS THE HEAT PUMP SET TO RUN AT THE CORRECT
TIME & DATE?
Please check your current timing or temperature modes on
your controller you may have programmed the unit to turn on
at a different time.
IS THE CURRENT POOL/SPA WATER TEMP HIGHER
THAN THE SET TEMP ON THE CONTROLLER?
If so the unit will not operate until the pool/spa water
temperature falls below the set temperature on the controller.
HEAT PUMP IS RUNNING BUT NOT HEATING, CHECK THE FOLLOWING:
IS THE FAN
FUNCTIONING?
If not contact
EvoHeat tech support
on 1300 859 933
IS THE AIR DISCHARGED FROM THE TOP OF THE FAN NOTICEABLY COOLER THAN
THE AMBIENT TEMPERATURE?
If not, check the refrigerant gauge on the bottom panel of the heater. Another way to determine if the
heater 
temp is higher than the WATER IN temp. Check also the INLET WATER TEMP is lower than the HEAT
TEMP set point.
If the gauge shows less than 0.8MPA contact EvoHeat tech support to check the refrigerant system.
Example of empty (loss of
refrigerant)
Example of normal (Note: can
vary based on ambient
temperature)
Ensure sufficient fresh airflow around the unit as per installation instructions.
Make sure cold air discharged does not recycle back through the heater. Check the condenser fins. If

IF THE HEAT PUMP IS RUNNING CONTINUOUSLY, CHECK THE FOLLOWING:
•Check the set temperature is at your desired level and that the pool water temperature is at or below this set point.
•Alternatively, this could be a possible electrical component failure contact EvoHeat tech support.
WATER APPEARING AROUND THE BASE OF THE UNIT, CHECK THE FOLLOWING:
The water appearing around the base of your heat pump could be condensation or a possible water leak. To determine, check
the following:
•Check the discharge for the presence of chlorine.
•Turn the heater off & run the water pump
continuously for a period of 2-4 hours.
If the water has no chlorine then it is condensation and is it normal –
see drainage and condensation for more information. If the water
has chlorine, it is a water leak and you need to contact EvoHeat tech
support.
If the water dries out, then it was condensation –see
drainage and condensation for more information. If
there is a continuous leak contact EvoHeat tech
support.
