5. Installation
5.1 System Installation
The factory only provides the main unit and the water unit, other items in the illustration above are necessary spare
parts for the water system that are to be provided by the user or the installer.
ATTENTION
Please follow these steps when using for the first time:
1. Open valve and charge water
2. Make sure that the pump and the water-in pipe have been filled with water.
3. Close the valve and start the unit.
NOTE: It is necessary that the water-in pipe is higher than the pool surface.
The schematic diagram is for reference only. Please check the water inlet/outlet label on the heat pump while plumbing the unit.
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.
•Heater Condition
•Location
•Clearances & Air Flow
•Adequate water flow & plumbing
•Correct electrical connection & supply
5.2 Heater Condition
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.
NOTE: All accessories (drain barb, rubber feet, Wi-Fi module and barrel unions) and installation manuals are inside the DHP-R
service panel. Please ensure to remove the service panel to locate these items.

EvoHeat Force-i Series Manual
5.3 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.
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.
The heat pump should be installed a maximum of 5m below the water level of the pool/spa.
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 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.
In the event that a suitable outdoor location is unavailable please contact Evo Industries for specialist technical
advice ON 1300 859 933.
5.4 Airflow Clearances
The heat pump unit needs continuous fresh air whilst running. The heater draws up to 80m3/min 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 600mm on the sides and 1500mm overhead clearance.
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.

10
EvoHeat Force-i Series Manual
5.5 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.
5.6 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.
5.7 Condensate Drain Barb
Fit the condensate drain barb into the 2 holes under the unit if you need to
direct water away from the heater. Put in hot water if stiff.
5.8 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 degC. 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.
5.9 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.
Standard model 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.

EvoHeat Force-i Series Manual
5.10 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.
Correct phase connection is important with 3 phase heaters. NOTE: 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.
