INTRODUCTION
The new PAC 36 is a highly versatile electronically-
controlled air-conditioner: it can be used as a
manual or automatic air-conditioner during the
summer.
This conditioner consists of two units: the internal
unit is designed to operate inside the room to be
conditioned; the external unit is installed in the
open.
The two units are connected by a special hose,
approximately 3,5 metres in length. This hose
contains the freon tubes, the electrical wiring and
the condensation discharge tube.
This appliance also has a SLEEP function. This
function activates a program studied and
designed to increase comfort during sleeping
hours. The program not only ensures perfect
silence (from both the internal and external units)
but also controls the temperature of the
environment, without lowering it excessively, to
produce the healthiest conditions.

INSTALLATION
MODELS WITHOUT SPECIAL COUPLINGS
The hose which connects the internal unit to the
external unit can be positioned in two ways:
In this case, it is necessary to disconnect the
internal unit as follows:
1) Remove the plug from the wall socket.
2) Remove the rear panel (on the back of the
appliance) by unscrewing the four retaining
screws.
3) Remove the metal brackets which fasten the
hose to the appliance (N. 3).
4) Using a 24mm spanner, unscrew the union on
the coupling. When doing this, use a 19mm.
spanner to block the extrimity of the hose in
position.
Repeat this operation for the second union.
The path of the connector hose should be as
straight as possible, without sharp curves or
kinks.
5) Detach the condensation hose from its
coupling.
6) Disconnect the electrical connector socket
by pressing the two retainer tabs.
a) Through a slightly-open window or door.
MODELS WITH SPECIAL COUPLINGS
If your air-conditioner is fitted with the special
rapid-fit coupling, the hose which connects the
internal unit to the external unit can also be
passed through a round hole in an external wall
(diameter: 6 cm. approx.).
ø6
cm 30
Frame for hose
b) Through a small hole (5.5 x 2.5 cm.) in the
lower part of the door or window frame. In this
case, it is necessary to use the special frame
for the connection hose.

20
To re-connect the ends of the connector hose to
the internal unit, repeat steps 1 to 6 in reverse
order. The following precautions should be
observed:
•Before passing the connector hose through the
hole in the wall, the threaded ends of the rapid
couplings should be protected using insulating
tape or similar.
•Fit the two upper refrigerant couplings to the
two lower couplings and tighten by hand,
ensuring that they are correctly connected.
Then use the spanner to tighten fully.
•After connecting the two refrigerant couplings,
fasten the brackets.
•Check that the refrigerant couplings are sealed
perfectly by wetting the couplings with a little
soapy water. No soap bubbles should form.
Attention
Connection and disconnection of the refrigerant
couplings should be carried out by qualified
personnel.
The external unit can also be mounted on a wall.
In this case, use the special wall-mount brackets.
EXTERNAL UNIT
The external unit can be positioned on a terrace
or balcony. In this case, it is not necessary to use
the fixing brackets.
Alternatively, for temporary installation, the
external unit can be hung as shown in the figure.
In this case, use the special support belts
(supplied with the appliance).
The external unit can be installed above or at the
same level as the internal unit, provided that the
difference in height between the two units does
not exceed 1.5 m.
The intake and outlet vents must not be obstructed.
Leave a space of at least 6 cm. between the rear
of the unit and the wall.
The condensation which forms when the unit is
used for air-conditioning (i.e. in summer)
evaporates from the external unit.
If the humidity is particularly high, it may be
necessary to fit the condensation discharge tube
(supplied with the machine). In this case, fit the
hose to the coupling on the bottom section of the
external unit (remove the rubber cap from the
coupling).
In the event there is still some condensation to be
eliminated and the equipment is connected to its
electrical feed, the waste pump may turn on
spontaneously to get rid of that excess moisture
even if the equipment itself has been turned off.
In order to guarantee the greatest possible
operational efficiency, you are advised to position
the external unit in such a way that it will not be
directly exposed to sun rays, rain etc.
INTERNAL UNIT
The internal unit should be installed in the room to
be conditioned. Generally,the ideal position for
the internal unit is under a window. In any case, it
should be positioned near an external wall.
The internal unit must be perfectly level. If
necessary, use the castor stops supplied with the
machine.
The air intake and outlet grilles should not be
obstructed in any way.

FINAL CHECK
In order to ensure that your air-conditioner
operates with the maximum efficiency, make sure
that:
•all doors and windows in the room to be air-
conditioned are closed (except for temporary
installation, in which case a window must be left
partially open).

SETTING THE TIMER
Ther programmer/timer, like all clocks, must be
set to the exact time. If for example it is 4.00 p.m.
(16.00), turn the dial in a clockwise direction
(following the direction of the arrow) until the
number 16 is lined up with the tringular pointer
(the arrows indicates 4:00 p.m. approximately).
N.B.: Never turn the dial in anti-clockwise direction!
The timer is in effect, an electric clock and works
only if the plug is connected to the power supply.
Whenever the plug is disconnected or there is a
power failure, the programmer stops (the clock is
then "slow" and must be re-set.
Select operation "with timer" or "without timer".

For technical reasons, the temperature is not
expressed in degrees but by a line increasing in
thickness. We therefore recommend that when
starting up the appliance, the thermostat be
turned to maximum (thick green line = maximum
cold). When the desired temperature has been
reached move the thermostat slider slowly away
from the maximum cold position until the
appliance is switched off by operation of the
thermostat. In this way the appliance has been
programmed with the exact temperature degree
required, which is then maintained automatically
by the thermostat.
