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.
