Locating indoor unit
1. Do not place objects near the air dis-
charge so the air may be distributed
throughout the room.
2. Make sure the indoor unit is installed
firmly and in horizontal position.
3. Select a location that can support 4 times
the weight of the unit so as to decrease
noise level due to vibration.
4. Select a location where it is easy to install
the drain, and as close to the outdoor unit
as possible.
5. Make sure there is sufficient clearance
for all maintenance servicing.
6. Make sure the suspension system can
support 4 times the weight of the unit
so as to avoid saturation (permanent
compression).
Note:
1. Keep a reasonable distance from the
kitchen.
2. This equipment should not be installed
in laundry rooms.

Installing the indoor unit
4 and 4a)
1. Locate the indoor unit.
- Fasten the support to the fastening
bolts. Make sure they are firm and use
nuts and washers on both top and bot-
tom of the support. The fastening plate
or fasteners (1) avoid movement of the
washers.
- Use template (2) to establish the dimen-
sions of the opening in the ceiling.
- The centre of both the opening in the
ceiling as well as the unit are indicated
on the template supplied with this equip-
ment.
- Fasten the template to the indoor unit
with screws (3) x 3.
2. Locate the unit in correct position for
installation.
3. Make sure the unit is in horizontal posi-
tion (with a level).
- The indoor unit is equipped with a pump
and float at each one of the four corners.
Check correct positioning with a level or
vinyl pipe. (If the unit is installed contrary
to condensed water flow, the float will not
operate correctly and could cause water
spilling.)
4. Remove the fastener from washers (1)
and screw in the top nut.
5. Remove the installation template (2).

Attention: Tighten the nuts to make sure
the unit does not fall.
Cooling connections (Fig. 5)
- Use both wrenches at the same time, as
shown in the following illustrations, to con-
nect and disconnect the cooling pipes.
- See Table 1 to determine correct torque
to be applied to the nuts. (Tightening in
excess could cause gas leaks.)
- When connecting pipes, cover both the
outer as well as inner sides of the pipes
with cooling machine oil, and tighten them
manually 3 or 4 turns.
- Check pipe connections for gas leaks, and
lay them as indicated below.
- Use the sealing filler (11) to insulate con-
nection (8).
