4.3 Installation of heat pump
(1) The heat pump must be installed by professional technicians, otherwise it may be damaged or
even broken.
(2) The unit is designed for outdoor location with good ventilation. Recirculation of cold discharge air
back into evaporator coil will greatly reduce heating capacity and efficiency of the unit, which will
void the compressor warranty.
(3) The unit can be installed almost anywhere in the outdoors. To get a good performance ,it needs
to meet the three factors :
a) Good ventilation
b) Stable and reliable power supply
c) Recycled water system
The difference from a gas water heater is, it should not bring environmental pollution or have
any installation problems in-windy areas.
(4) The unit should not be installed in a limited air ventilation area or placed in or near vegetation
that will block the air inlet.
These locations would deny the unit a continuous source of fresh air. When seasons change,
leaves maybe sucked onto the evaporator coil, thereby reducing its efficiency and impact on its
service life.
(5) For indoor installation, please request more instructions from your supplier and technicians.
(6) When a bypass is installed, flow should not exceed 30% of the nominal flow rate.
(7) Installer must make the water level higher than the circulation pump location. Unless a One-Way
Check Valve is used in the plumbing circuit.
(8) Typically, the pool heat pump unit should be installed aside a pool, less than 7.5 meters distance. But,
at least 2m away from the pool so a person cannot touch the pool and the heat pump at the same time,
as this would lead to electrical safety concerns.
(9) To get the best from the heat exchanger of the heat pump unit, it should be matched with the
nominal flow rate of water flow recommended in the specification sheet.
(10) We consider it good practice to place a discharge pipe in the lowest pipe to prevent freezing in
cold season. Put "T" fitting and ball valve to facilitate discharging the water in winter or emptying the
water out of the system to prevent freezing when the HP stops operating at the ambient
temperature below 3c, otherwise the unit may be damaged.
(11) It is suggested to install the quick adapter in front of the water in-out connection, which could
discharge water easily to prevent water freezing. This would be convenient for maintenance and
servicing.
(12) When the unit is running, there will be some condensation water discharged from the bottom.
For Summer Spring and Autumn use, please hold the drainage nozzle (accessory) into the hole
and clip well, then connect a pipe to drain the condensation water out. This tube and drain "IF"
used must be checked for blockages regularly as leaves and debris will block this.
