Connection to adjacent room

The indoor unit can also be used 
to cool an adjacent room through 
a duct system, e.g. hidden behind 
a suspended ceiling. The following 
conditions must be met:

■ 

The rated cooling output of the 
indoor unit must be sufficient 
for both rooms.

■ 

An opening must be made 
between both rooms to allow 
the air to circulate.

■ 

The maximum pipe length of 
7 m should not be exceeded.

■ 

In order to ensure that the air 
is transported to the adjacent 
room, close off 1 or 2 of the 
four outlets on the cover. Stick 
a black single-sided adhesive 
fabric strip over the outlet 
openings being covered. This 
strip must be able to withstand 
the effects of a continual air 
flow.

Fresh air intake

As already mentioned, the indoor 
unit can also be employed to suck 
in and regulate the temperature of 
fresh (outdoor) air in addition to 
room air.
This is the preferred option for 
rooms with a high rate of air 
consumption.

■ 

Observe the regional 
regulations concerning air 
treatment.

■ 

Fit a collar with a nominal 
diameter of 70 mm to the fresh 
air intake.

■ 

The fresh air content should not 
exceed 10 % of the nominal 
air flow rate for the equipment. 
The fresh air supply should 
be controlled by an additional 
speed-regulated fan.

■ 

The air at the outdoor air intake 
should be sucked in through 
a dust filter at a maximum 
rate of 2.5 m/s to prevent the 
ingress of rain water.

■ 

The fan should be connected to 
a separately protected electrical 
supply (to be provided by the 
customer).
