NOTICE

Do NOT install the unit tilted. Possible consequence: If
the unit is tilted against the direction of the condensate flow
(the drain piping side is raised), the float switch might
malfunction and cause water to drip.

4.1.2 Guidelines when installing the drain piping

Make sure condensation water can be evacuated properly. This
involves:

▪ General guidelines

▪ Connecting the drain piping to the indoor unit

▪ Checking for water leaks

General guidelines

▪ Pipe length. Keep drain piping as short as possible.
▪ Pipe size. Keep the pipe size equal to or greater than that of the

connecting pipe (vinyl pipe of 25 mm nominal diameter and
32mm outer diameter).

▪ Slope. Make sure the drain piping slopes down (at least 1/100) to

prevent air from being trapped in the piping. Use hanging bars as
shown.

c Rising drain piping (vinyl pipe of 25mm nominal diameter

and 32mm outer diameter) (field supply)

d Hanging bars (field supply)

▪ Condensation. Take measures against condensation. Insulate

the complete drain piping in the building.

▪ Combining drain pipes. You can combine drain pipes. Make

sure to use drain pipes and T-joints with a correct gauge for the
operating capacity of the units.

▪ To protect the unit, turn on the main power switch 6 hours before

operation.

▪ If the main power supply is turned off during operation, operation

will restart automatically after the power turns back on again.

12.2.2 About cooling, heating, fan only, and automatic operation

▪ The air flow rate may adjust itself depending on the room

temperature or the fan may stop immediately. This is not a
malfunction.

12.2.3 About the heating operation

It may take longer to reach the set temperature for general heating
operation than for cooling operation.

The following operation is performed in order to prevent the heating
capacity from dropping or cold air from blowing.

Defrost operation

In heating operation, freezing of the outdoor unit's air cooled coil
increases over time, restricting the energy transfer to the outdoor
unit's coil. Heating capability decreases and the system needs to go
into defrost operation to be able to remove frost from the outdoor
unit’s coil. During defrost operation the heating capacity on the
indoor unit side will temporarily drop until defrosting is completed.
After defrosting, the unit will regain its full heating capacity.

The indoor unit will stop fan operation, the refrigerant cycle will
reverse and energy from inside the building will be used to defrost
the outdoor unit coil.

The indoor unit will indicate defrost operation on the display .

Hot start

In order to prevent cold air from blowing out of an indoor unit at the
start of heating operation, the indoor fan is automatically stopped.

The display of the user interface shows . It may take some
time before the fan starts. This is not a malfunction.
