Two-Room and Fresh Air
Connection
The indoor unit is designed to cool a second room and,
independently of this, to suction in fresh air.
On each side of the unit, there is a pre-punched open-
ing of Ø 150 mm across from one another for connec-
tion to a second room and a pre-punched opening on
the corner of the unit for the fresh air connection.
The corresponding openings must be broken through
when necessary. Prior to doing this, the circular insula-
tion must be carefully removed. Remember that directly
behind the insulation to be removed are the plate fins of
the heat-exchanger and that these may by no means be
damaged.
Two-room connection
With the ceiling cassette, you can cool an adjacent
room via a duct system, e.g. in a suspended ceiling.
The following conditions must be met:
à The cooling capacity of the cassette must be ade-
quate for cooling both rooms.
à There must be an opening created between the two
rooms that allows the air to circulate between them.
à A maximum pipe length of 7 m may not be exceeded.
Both connections must house heat insulation! The
pipes and installed parts must be insulated with at
least 30 mm of aluminium-clad mineral cotton or
13 mm arm of flax .
G
à Only one two-room connection may be used.
à To settle the second-room connection, a flanged col-
lar with a minimum diameter of NW 150 mm/156
mm must be attached to the opening with metal
screws (Ø 3 - 4.5 mm, max. 10 mm). A flanged col-
lar NW 100 is mounted for the fresh air connection.
à To ensure that air is transported to the adjacent
room, 1 or 2 of the 4 plate fins are to be sealed on
the indoor unit. To do this, use a black strip with ad-
hesive on one side which is stuck to the opening(s)
to be sealed. The strip must be able to withstand the
strain from the air pressure permanently.
à The flanged collar, screws, flexible / folded spiral-
seam pipes and insulation materials must be pro-
vided by the customer. These parts can all be pur-
chased from your dealer.
à The ventilation pipes should be kept as short as
possible and should be laid with as few bends as
possible.

Installing the two-room connection
Fresh air connection
As already described, it is possible to suction in fresh air
(outside air) with the indoor unit in addition to the room
air and regulate the temperature. This option is prefer-
able in rooms where air is consumed quickly.
à There may not be more than 10 % fresh air, other-
wise the unit may not work properly.
à An air filter must be installed on the fresh air intake
(customer-installed) or in the air duct.
à To prevent rainwater from entering the unit, the air
may only be suctioned in by the fresh air intake at a
maximum speed of 2.5 m/s.
à Fresh air can be supplied using an extra fan.
à To ensure that the first air current is correctly ad-
justed, we recommend using a speed regulator.
à To connect the fan, it is necessary for the customer
to install a separately fused electrical installation.
à Mount the fresh air pipe in such a way that the corre-
sponding opening can be broken and the polystrol
separating wall underneath it can be cut out.
à The polystrol plate surrounding the collection tray
shown in the photo must be removed with a knife.
