4. Installation
4.1 System Installation
I
The schematic diagram is for reference only. Please check the water inlet/outlet label on the heat pump while
plumbing the unit.
INSTALLATION ITEMS
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 & Air Flow
•Adequate water flow & plumbing
•Correct electrical connection & supply

EvoHeat CS-i Commercial Inverter Series Heat Pump
4.2 Location Recommendations
Installation and service must be performed by a qualified installer.
Evo recommend the heat pump should 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 heat pump should be installed on a flat level surface as close as possible to the pool.
The Evo pool heat pump should be installed with a minimum clearance of at least 3.5m to the water’s edge.
Furthermore, EvoHeat recommend installing the heat pump no greater than 7.5 meters away from the water’s edge
due to heat loss from the piping.
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.
The heat pump should be installed a maximum of 5m below the water level of the pool/spa. If further than 5M
please discuss with your EvoHeat specialist for the best advice.
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 rainwater mixed with debris from the roof to be forced
through the unit. A water deflector may be needed to protect the heat pump.
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 and
3500mm overhead clearance.
When units of a similar height are placed side by
side, EvoHeat recommend a 1500mm clearance between units.
*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.
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.

EvoHeat CS-i Commercial Inverter Series Heat Pump
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!
Removal of condensation can be achieved via the installation of a condensate pan or by plumbing to a waste
water drain. If plumbing, EvoHeat recommend raising the heat pump of the ground approximately 100mm to
allow enough space to connect the condensate lines under the heat pump together, then drain to a wastewater
drain.
4.7 Plumbing
The Swimming Pool 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.
The CS-i65 comes supplied with barrel unions for the
Inlet/Outlet connections which accepts 50mm PVC pipe.
The CS-i130 has 100mm PVC flange connections for the Inlet/Outlet connections.
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.

EvoHeat CS-i Commercial Inverter Series Heat Pump
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.
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
EvoHeat have developed a YouTube Channel where you will find useful videos - from setting up
your timers to setting up the EvoHeat app. View it to see resolutions to some of our most asked,
yet easily solved questions: https://www.youtube.com/channel/UCfYiOxHuybBuC1NZcqUnrcA
IF YOUR HEAT PUMP ISN’T 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.
• Is the current pool/spa water temperature higher than the set temperature on the controller?
If so the unit will not operate until the pool/spa water temperature falls below the set temperature on the
controller.
• Is your heat pump set to run at the correct time and 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.
• Does your heat pump have an error message on the screen?
If yes, refer to the error code table 19.
IF YOUR HEAT PUMP IS RUNNING BUT NO 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 is
working correctly is to look at the controller’s screen and check to see if the WATER OUT 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)

13
EvoHeat CS-i Commercial Inverter Series Heat Pump
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 they are dirty
or blocked use a low flow garden hose only (Pressurised water may cause damage to the heater).
• The unit will periodically defrost when the ambient air temperature is lower than 8 degrees C.
IF YOUR 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 on 1300 859 933
IF YOUR HEAT PUMP HAS 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.
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 on 1300 859
933. Or…
• Turn the heater off and run the water pump continuously for a period of 2-4 hours.
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 on 1300 859 933.
DRAINAGE & CONDENSATION
Whilst the heater is operating, water in the air condenses on the fins of the evaporator. In the instance 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 heater will automatically activate reverse cycle or de-icing mode when required which also increases condensate
discharge. This normally occurs at temperatures below 8°C. The condensate water will discharge through the base of
the heater. As an option a pipe can be connected to the drain on the base of the unit to direct condensate water to
an appropriate location.
NOTE: A quick way to verify that the water is condensation is to shut off the unit and keep the pool pump running. If
the water stops running out of the basepan, it is condensation. AN EVEN QUICKER WAY IS to TEST THE DRAIN WATER
FOR CHLORINE – if the is no chlorine present, then it’s condensation.
