6.2 Filter assembly
• Fit the filter, if provided as an accessory, once all
electrical work has been completed, the water
connections have been made and the condensation
pump connected.
• The instructions for fitting the filter hood can be
found in separate installation instructions. Simple
filter attachments with a ring are simply placed
over the motor guard. Then fit the air intake
crown.
6.3 Installation of the air intake crown
Caution!
Only fit the air intake crown once all
connection and installation work has been completed.
The terminal box, valves, motor guard, condensation
pump etc. can no longer be accessed once the air
intake crown has been fitted.
The air intake crown is supplied as standard and
serves as an intake grille with recirculation air units,
and as a casing and mixed air units. When the Ultra
is fitted directly onto a solid ceiling and pipes are run
under the ceiling, the air intake crown cannot be
fitted as intended. In this case, it can optionally either
be omitted entirely or adapted on site, for instance by
removing partial segments of the grille.
Before fitting, first loosely connect the individual
sections to each other. Once fitted, they become
more stable on the Ultra base plate.
Caution!
The air intake crown sections may
have sharp edges! Risk of injury!
• First screw one of the screws provided into the
screw hole provided on each of the six sections
(2nd opening from the bottom, see detailed
diagram).
• Insert 2 individual parts of the intake crown
together and screw them together through the
2nd bottom opening in the louvre.
• Then place the sections in the appropriate position
on the base plate of the Ultra (see diagram on
page 13 or the drilling template on the cardboard
packaging). The louvres should be pointing
downwards!
• Then screw the sections to each other by tightening
each screw.
Caution!
Make sure that the gap between the ceiling
and the air intake crown is maintained and not filled
by subsequent work on the ceiling, such as plastering,
to ensure that it is possible to subsequently remove
the air intake crown.
