INSTALLATION
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.
Transportation
- When storing or moving the heat pump, the heat pump should be in an upright position. Never Tilt the unit more than 30 degrees.
- 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.
Notice Before Installation
- 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!
- To ensure heating efficiency, the length of the piping between the pool and the heat pump should be less than 30ft.
Installation Instructions
3.3.1 Pre-requirements
Equipment necessary for the installation of your heat pump:
- Power supply cable suitable for the unit’s power requirements and compliant with your local regulations.
- A By-Pass kit, sufficient PVC tubing suitable for your installation, as well as PVC , PVC adhesive and sandpaper.
- A set of wall plugs and expansion screws suitable to attach the unit to your support or base.
- We recommend that you connect the unit to your installation by means of well supported flexible PVC pipes to reduce the transmission of vibrations.
- Suitable fastening studs may be used to raise the unit.
Heat Pump Installation
- The 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. - The heat pump needs a water pump (Supplied by the user). Max. lift 30ft;
- When 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.
Location and Size
Please comply with the following rules concerning the choice of heat pump location.
- The unit’s location must be easily accessible for convenient operation and maintenance.
- It 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.
- A water drainage device must be provided close to the unit in order to protect the area where it is installed.
- If necessary, the unit may be raised by using suitable mounting pads designed to support its weight.
- Check 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.
- The unit must not be installed in an area exposed to oil, flammable gases, corrosive products, sulfur compounds or close to high frequency equipment.
- To prevent external damage to the unit, do not install it near a road or track.
- To avoid causing nuisance to neighbors, make sure the unit is installed in an area that is not sensitive to noise.
- Keep the unit out of the reach of children.
- Installation space:
Unit: mm
Do not put anything less than 1500mm (5ft) in front of the heat pump.
Leave 500mm (2ft) of empty space on the sides and back of the heat pump and free space for air circulation above
Do not leave any obstacles above or in front of the device!

Notice: The filter must be cleaned regularly to ensure that water in the system is clean and to avoid lack of water flow. It is necessary that a drainage valve is fixed at the lowest point in the lower water pipe to completely drain water out of the system for winterizing. If the unit is not running during winter months, please disconnect power supply and drain water from the unit through the drainage valve or by disconnecting the quick connect fittings. If unit is used at ambient temperatures below 0℃, please keep ensure that the water pump continuously runs to avoid water freezing inside the machine.
Electrical Installation
To function safely and maintain the integrity of your electrical system, the unit must be connected to your electrical supply in accordance with the following regulations:
- The heat pump must be connected to a suitable circuit breaker in accordance with current standards and regulations in the country where the system is installed.
- The electrical supply cable must be adapted to match the unit’s rated power and the length of wiring required for the installation. The cable must be suitable for outdoor use.
- In places open to the public, or where required by law, an emergency stop button or power disconnect switch should be installed near the heat pump.
