Installation

Precautions

• Avoid locating the unit close to bedrooms or other noise sensitive areas.

• Avoid a location which could create vibration (e.g. secured to a solid wall).

• The fan should not blow towards windows, walls or spaces likely to be inhabited by people or animals.

• Do not install where the Heat pump is likely to be subjected to polluted air, dust or debris, etc.

• Avoid directing fan output against the dominant wind directions.

• Protect the heat pump from possible snow fall.

• Minimise exposure to environmental conditions as much as possible and never block the airﬂow.

Securing the Heat pump

The Heat pump should be securely ﬁxed. The four included rubber mounts should be installed to absorb

high-frequency vibrations.

Piping

A bypass, consisting of three valves, must be installed to adjust water ﬂow to the Heat pump and to isolate the

apparatus for maintenance purpose.

For a more stable ﬂow in the heat exchanger, it is recommended to install the Heat pump on the pressure side of the

main pump.

In order to limit the heat loss from the piping,

it is recommended to install the heat pump as close

as possible to the spa. A 16 foot (5 m) cord is provided.

If your installation is equipped with a water treatment system (chlorine, bromine, salt, etc.) the bypass must be installed

before the water treatment, with a check valve between the bypass and water treatment system.

Condensation

The air drawn into the Heat pump is strongly cooled by the operation of the Heat pump for heating the spa water, which

maycause condensation on the ﬁns of the evaporator. The amount of water may be as much as several liters per hour

at high relative humidity. This is sometimes mistakenly regarded as a water leak.

Since water generated by condensation will be evacuated at the bottom of the Heat pump, it is better to provide a slight

rearward slope when installing the Heat pump to allow this water to ﬂow freely on the ground. It must also be ensured

that this evacuation of water will not affect any components around the Heat pump like electrical circuit and material like

wood ormetal that can be weakened by water That said, be aware that water will ﬂow under the Heat pump in normal

operation.
