Drain work
Check in the combination table under "Possible options" on page 3
whether drain work is allowed. In case drain work on your unit is
allowed and the installation site requires drain work, then follow the
guidelines below.
■
Drain kits for drainage are available as option.
■
If drain work from the unit causes trouble (for example, if the
drain water may splash on people) provide the drain piping using
a drain socket (optional).
■
Make sure the drain works properly.
Installation method for prevention of falling over
If it is necessary to prevent the unit from falling over, install as shown
in the figure.
■
prepare all 4 wires as indicated in the drawing
■
unscrew the top plate at the 4 locations indicated A and B
■
put the screws through the nooses and screw them back tight
Installation servicing space
The numerical figures used in the figures represent the dimensions in
mm.
(Refer to "Precautions on installation" on page 4 )
Precaution
(A) In case of non-stacked installation (See figure 1)
(B) In case of stacked installation
1. In case obstacles exist in front of the outlet side.
2. In case obstacles exist in front of the air inlet.
Do not stack more than one unit.
About 100 mm is required as the dimension for laying the upper unit's
drain pipe. Get the portion A sealed so that air from the outlet does
not bypass.
(C) In case of multiple-row installation (for roof top use, etc.)
1. In case of installing one unit per row.
2. In case of installing multiple units (2 units or more) in lateral
connection per row.
Relation of dimensions of H, A and L are shown in the table below.
NOTE If drain holes of the unit
are covered by a mounting
base or by floor surface,
raise the unit in order to
provide a free space of
more than 100 mm under
the unit.
A Location of the 2 fixation holes on the front side of the unit
B Location of the 2 fixation holes on the rear side of the unit
C Wires: field supply
Suction side obstacle
✓
Obstacle is present
Discharge side obstacle
1 In these cases, close the
bottom of the installation
frame to prevent the
discharged air from
being bypassed
Left side obstacle
Right side obstacle
2 In these cases, only
2 units can be installed.
Top side obstacle
This situation is not
allowed
NOTE Minimum distance B1 in figure 1 mentions the
space required for correct operation of the unit.
Required space for servicing though is 300 mm.
