The indoor unit should be installed in an indoor water proof place, or the safety of the unit and the operator cannot be

ensured.

CAUTION

The indoor unit is to be wall mounted in an indoor location that meets the following requirements:

The installation location is frost-free.
The space around the unit is adequate for serving, see figure 4-4.
The space around the unit allows for sufficient air circulation.
There is a provision for condensate drain and pressure relief valve blow-off.

When the unit running in the cooling mode, condensate may drop from the water inlet and water outlet pipes. Please make

sure the dropping condensate will not result in damage of your furniture and other devices.

CAUTION

The installation surface is a flat and vertical non-combustible wall, capable of supporting the operation weight of the unit.
All piping lengths and distance have been taken into consideration.

Requirement

Maximum allowable piping length between the 3-way valve SV1 and the indoor unit

(only for installations with domestic hot water tank)

Maximum allowable piping length between the domestic hot water tank and the indoor unit

(only for installations with domestic hot water tank). The temperature sensor cable supplied

with the indoor unit is 10m in length.

Table 3-1

Maximum allowable piping length between the TW2 and the indoor unit. The temperature

sensor a cable of TW2 supplied with the indoor unit is 10m in length.
