1) The provision of the clearances shown in 1.a above are important to achieving the maximum heating
performance and efficiency of your heat pump. If clearances are compromised, this creates the
potential for the cold air discharged at the rear of the unit (through the evaporator) to recirculate so that
the air being used for heat capture is cooler than the true ambient (outside) temperature. This issue of
recirculation is particularly worsened if the surrounding area is not open or if the heat pump position is
for example, directly under the eave of your home. The intent in selecting the installation position and in
considering the potential to place other plant nearby is to achieve the maximum open area around the
heater. As such, the clearance guidelines given should be understood as the minimum recommended
and wider spacing will be beneficial in terms of minimizing the risk of air recirculation.
2) The frame of the unit must be fixed by bolts (M10) to a solid or concrete foundation. The foundation must be
secure.
3) Do not stack obstacles near the inlet or outlet area of the heater fan/s or evaporator coil/s and ensure there is
a minimum of 500mm behind the main machine’s evaporator coil, otherwise the efficiency of the unit may be
compromised. It may also cause the unit to stop working.
4) The machine needs a circulation pump (supplied by the others) to operate. The heat pump unit can be
energised by either a main filter pump or separate circulation pump. This will depend on the preferred method
of installation. Please refer to the minimum flow rate of the unit being installed to select a pump for the
required water flowrates.
5) When the machine is running, there will be condensate water discharging from the bottom of the unit, please
pay attention to this. There is a condensate drainage nozzle (accessory) supplied. Please ensure this is placed
into the condensate drainage hole on the bottom of unit and clipped in. Then connect a PVC pipe to this and
run it to an approved plumbing drainage point.
