Install the fan coil unit
Q
Keep piping as short as possible and slope it downwards at a
gradient of at least 1/100 so that air does not remain trapped
inside the pipe. Refer to
“Drain pipe installation” on page 8 .
If the drain hose cannot be sufficiently set on a slope, fit the drain
hose with a drain raising piping (field supply) as illustrated in
figure 7: “How to perform drain piping”.
Q
Keep pipe size equal to or greater than that of the connecting
pipe (25 mm inner diameter).
Q
Install the drain raising pipes at a height of less than 675 mm.
Q
Install the drain raising pipes at a right angle to unit and no more
than 300 mm from the unit.
Q
To prevent air bubbles, install the drain hose level or slightly tilted
up (
≤ 75 mm).
Q
Insulate the complete drain piping inside the building.

4.7.2. Connect the drain piping to the unit
1 Push the drain hose (delivered with the unit) as far as possible
over the drain socket as illustrated in the figure below.
Fig. 4.8: Connecting the drain hose
2 Tighten the metal clamp until the screw head is less than 4 mm
from the metal clamp part as illustrated in figure 8: “Wrap sealing
pad”.
3 Wrap the large sealing pad (as illustrated in figure 8: “Wrap
sealing pad”) over the metal clamp and drain hose and fix it with
clamps.
Install the fan coil unit
4.7.3. Test the drain piping
After the drain piping work is finished, check if drainage flows
smoothly.
1
Add approximately 1 l of water gradually through the air outlet
(See figure 10: “Method of adding water”).
2 Check the drainage flow.
3 After the testing of drain piping is finished, attach the drain
sealing pad (delivered with the unit) over the uncovered part of
the drain socket (between drain hose (delivered with the unit) and
unit body) as illustrated in figure 8: “Wrap sealing pad”.
Install the fan coil unit
4.8. Install optional equipment
For the installation of optional equipment, refer to the installation
manual which is delivered with the optional equipment and take into
account the remarks mentioned in the table below.

Information
When unifying multiple drain pipes, install the pipes as
illustrated in figure 17: “Unifying multiple drain pipes”.
Select converging drain pipes whose size is suitable for the
operating capacity of the unit.

Q
In case the electric wiring work is finished
Check drainage flow during COOL running, explained in “Test
the installation” on page 11 .
Q
In case electric wiring work is not finished
1 Remove the control box cover. Connect the power
supply (50 Hz, 220-240 V) to connections L and N on
the power supply terminal block and connect the
ground wire firmly.
2 Close the control box cover and turn on the power.
Danger: electric shock
Do not touch the drain pump.
3 Confirm the drain operation looking at the drain
socket.
4 After checking the drainage flow, turn off power,
remove the control box cover and disconnect the
power supply from the power supply terminal block
again. Fit the control box cover back in place.
