Condensate Discharge - Swegon CASA W4 Smart Installation, Operation And Maintenance Instructions

the ceiling mounting frame through the selected holes
towards the nuts of the threaded rods and lock the
frame into position with nuts from underneath. Adapt
the installation height so that the locking screws in the
ceiling mounting frame's front section will extend suf-
ficiently far below the ceiling.

Important
If you improperly tighten the ceiling
mounting frame, this could turn the frame
and the ventilation unit will not have room
inside the frame.
Run the mounting hooks through the assembly open-
ings above the ventilation unit and secure them with
tension rivets. Position the hooks so that the sharp point
is facing the rear side of the ventilation unit.
The hooks must absolutely not be secured with riv-
ets directly above the ventilation unit.
The points of the hooks face the rear part of the ventilation
unit and they are to be slipped into the unit's notches before
you secure them with rivets.
Before you lift the ventilation unit into position, back
off the two screws at the front of the ceiling mounting
frame so much that the screw heads stick out approx. 2
cm. Also run the power supply and data cables, and on
the Econo model the water pipes, through the ceiling
mounting frame.
The ventilation unit's inspection door and heat ex-
changer can be removed to make it easier to lift the
unit. The fans can also be removed if necessary. See the
"Servicing" Section.
Lift the ventilation unit up against the ceiling mounting
frame so that all four locking hooks engage into posi-
tion. There are two catches on each locking hook. The
purpose of the upper one is to secure the ventilation
unit to facilitate connection to the ducts and the wiring
of the electric cables.
When the unit is in the correct position in relation to the
duct and the electric cables and water pipes, if required,
have been run into the ventilation unit, lift up the unit
to rest on the lower hooks. When the hooks are locked,
the spring-loaded screws of the front section of the
ceiling mounting frame extend outward. Finally, lock the
ventilation unit into position by tightening the screws.
Be careful not to press on the screws, because do-
ing so will disengage the ventilation unit.

Finally, lock the ventilation unit at its final location by
lightly tightening the locking screws.
The pipe connections of the Econo model should be ar-
ranged inside the ventilation unit. The connection work will
be facilitated if you temporarily remove the heat exchanger
and filter from the unit. Connect the inlet flow pipes to the
thermostat (3/8" female threads) and the return pipe in
the coupling with ∅Ø 15 mm on the ball valve.

2.2 Condensate discharge

Connect the discharge hose to the ventilation unit's
condensate discharge connection (3/8" male threads).
The condensate discharge water must be channelled
to a floor drain or the like using the supplied hose or a
hose with an inner diameter of at least 12 mm. The tube
must not be connected directly to the sewer. The tube
must not have a second water trap or be run horizon-
tally. The damming height of the water trap should be
at least 100 mm.
Hose to lead off the condensate is included in the deliv-
ery of the ventilation unit. The hose has a ready-made
loop that serves as a water trap.
