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).
