Installation
Unit installation
The unit is mounted with the cover
face down on four threaded rods.
Take into account the ceiling grid
and any other installations.
1. Use the dimensions
of the ceiling cassette
to mark the fixing points
for the threaded rods
on structural parts approved
to support the static load
above the suspended ceiling.
2. Fit any connection nozzles
before installing the unit
if connections to a second
room or a fresh air intake
are required.
See the "Connections
to a second room or a fresh air
intake" section.
3. Fit the unit onto the threaded
rods and use the lower nuts
to level the unit
(Fig. 6)
.
This ensures that the condensate
drains into the collection tray.
4. Make sure that clearance A,
as specified in the table below,
is maintained between
the underside of the suspended
unit and the underside
of the fastening
(Fig. 7)
.
5. Connect the refrigerant piping,
electrical cables and condensate
drainage line to the indoor unit
as described below.
6. Check again that the unit
is level.
7. The final task is to tighten
the counter nuts and attach
the cover.
Installation should only be
performed by authorised
specialists.

Connection for medium
piping
■
The piping connection provided
by the customer is carried out
on an angled side of the unit
on the KWD 25 EC-55 EC
and in the middle of the longer
side on the KWD 70 EC-100 EC.
■
For servicing purposes,
connections must be equipped
with shut-off valves and flow
volumes adjusted using valves
for hydronic balancing.
■
Additional automatic bleed
valves are to be provided
in the supply and return
at the installation's highest point.
■
The medium piping may not
exert any structural load
on the unit.
■
The line connections may
not generate any thermal
or mechanical stresses
on the unit.
If necessary cool the piping
or support with the second tool.
