3.1. Transportation
1. When storing or moving the heat pump, the heat pump should be in an upright position. Never
Tilt the unit more than 30 degrees
2.When moving the heat pump, do not lift it by the water unions as this may damage the titanium
heat exchanger inside the heat pump.
3.2. Notice Before Installation
1.The water unions are not designed to support the weight of unsupported flexible tubing. The
heat pump must be connected with properly supported tubing that does not pull or strain on the
heat pump unions!
2. To ensure heating efficiency, the length of the piping between the pool and the heat pump
should be less than 30ft.
3.3. Installation Instructions
WARNING: The heat pump must be installed by a qualified technician. Improper
installation, adjustment, service, maintenance or use can cause fire, electrical shock
or other conditions which may cause injury or property damage.
This section is provided for information purposes only and must be adapted according
to the actual site conditions.

3.3.1 Pre-requirements
Equipment necessary for the installation of your heat pump:
①Power supply cable suitable for the unit’s power requirements and compliant with your local
regulations.
②A By-Pass kit, sufficient PVC tubing suitable for your installation, as well as PVC , PVC
adhesive and sandpaper.
③A set of wall plugs and expansion screws suitable to attach the unit to your support or base.
④We recommend that you connect the unit to your installation by means of well supported
flexible PVC pipes to reduce the transmission of vibrations.
⑤Suitable fastening studs may be used to raise the unit.
3.3.2 Heat Pump Installation
①The heat pump must be fixed using bolts (M10) to a concrete foundation or suitable brackets.
The concrete foundation must be solid; the brackets must be strong enough and treated against
corrosion.
②The heat pump needs a water pump (Supplied by the user). Max. lift 30ft;
③When the heat pump is running, there will be condensate water discharged from the bottom
that must be properly managed and directed away from the heat pump. Please insert the drainage
tube (accessory) into the hole and clip it in properly, then connect a pipe to drain the condensate
water away. Install the heat pump, at least 3” off the ground with solid, water-resistant pads, then
connect the drainage pipe to the opening located under the heat pump.
3.3.3 Location and Size
Please comply with the following rules concerning the choice of heat pump location.
①The unit’s location must be easily accessible for convenient operation and maintenance.
②It must be installed on the ground, fixed ideally on a level concrete floor. Ensure that the floor
is sufficiently stable and can support the weight of the unit.
③A water drainage device must be provided close to the unit in order to protect the area where
it is installed.
④If necessary, the unit may be raised by using suitable mounting pads designed to support its
weight.
⑤Check that the unit is in a properly ventilated area, that the air outlet is not facing the windows
of neighboring buildings and that the exhaust air cannot return to the heat pump. In addition,
provide sufficient space around the unit for servicing and maintenance operations.
⑥The unit must not be installed in an area exposed to oil, flammable gases, corrosive products,
sulfur compounds or close to high frequency equipment.
