Unit Installation
– UH/U Units continued
Hanging Unit
l
Adjusting the positions of the nuts (lower side) so that
the distance between the washer (lower side) and the
ceiling is 138mm.
l
Hang the nut of hanger bolt on the U shape groove in
the body hanger.
l
Check the level of the body by using a spirit level.
l
Adjust the location and height of the indoor unit in
relation to the ceiling opening by using the installation
gauge provided in the template.
(A diagram to use the part is indicated on the installation
gauge)
(1) Ensure that the distance between the bottom of the
indoor unit and the underside of the ceiling is 43mm in
all 4 corners.
(2) Ensure the gap between the side of the indoor unit and
the ceiling is 30mm all the way around.
l
Tighten the upper nut and fix the position of the unit.
Precautions
Since the unit contains a drain pump and a float switch, the
body must be level.
If the body is installed in a tilted state, the float switch will
not function properly and thus will cause water leakage.
Installation of Ceiling Panel:
Install the ceiling panel following the installation manual sup-
plied with it.
Precautions
Before installing the ceiling panel, check that the body of
the unit has been installed correctly against the ceiling.
The ceiling panel and ceiling face must contact closely. The
ceiling panel and the contact side of the body must contact
closely. Any gap between them will cause air leakage and
thus generate condensation.
