Installation manual
6
Install the fan coil unit
3 Adjust the unit to the right position for installation.
Use the installation guide (delivered with the unit) for exact
vertical positioning of the unit.
Q
Apply the short side of the installation guide in case of
normal installation as illustrated below.
Fig. 4.2: Normal installation
Q
Apply the long side of the installation guide in case of
installation with fresh air intake kit as illustrated below.

4 Check if the unit is horizontally levelled.
Q
Do not install the unit tilted. The unit is equipped with a built-
in drain pump and float switch. If the unit is tilted against the
direction of the condensate flow (the drain piping side is
raised), the float switch may malfunction and cause water to
drip.
Q
Check if the unit is levelled at all four corners with a water
level or a water-filled vinyl tube as illustrated in the figure
below.

4.5.1. Connect the water pipes
The unit is equipped with water outlet and inlet connections. There is
an air purge valve that is fitted along with the water inlets and outlets
for air purging as illustrated in figure 6: “Water piping connection”.
Connect the water inlet and outlet connections of the fan coil unit to
the water piping as illustrated in figure 5: “Connecting the water
piping”.
In case the optional valve is used, refer to the installation manual of
the valve kit to install the field piping.
Install the fan coil unit
4.5.2. Insulate the water pipes
The complete water circuit, inclusive all piping, must be insulated to
prevent condensation and reduction of the capacity.
Fig. 4.5: Water piping insulation
If the temperature is higher than 30°C and the relative humidity is
higher than 80%, then the thickness of the sealing materials shall be
at least 20 mm in order to avoid condensation on the surface of the
sealing.
