4.5 Drainage & Condensation
During operation, water in the air condenses on the fins of the evaporator. In high humidity, the condensate
may be several litres per hour, giving the impression that the unit is leaking. This process 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.
Ensure the heat
pumps are installed level so condensate is not allowed to pool at one end of the condensate tray.
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.

OTE
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.
4.6 Plumbing
The unit’s exclusive rated flow titanium heat exchanger requires no special plumbing arrangements except bypass
(set the flow rate according to the nameplate). The water pressure drop is less than 10kPa at max.
Flow Rate
Location
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.
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.
4.7 Electrical Connection
Always use a qualified Electrician to perform any electrical work, they 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 the 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. The 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 or at the back of this manual.
