MH18AP1(P2)-09
MH19AP1(P2)-07
MH19AP1(P2)-12
B Type
MH24AP1(P2)-12
C Type
MH26AP1(P2)-07
MH26AP1(P2)-12

When deciding on the location of the air conditioner with the owner, the following restrictions
must be taken into account.
General
Do NOT install the air conditioner in a location where it will come into contact with the following elements:
◆Combustible gases
◆Saline air
◆Machine oil
◆Sulphide gas
◆Special environmental conditions
If you must install the unit in such conditions, first consult your dealer.
Indoor Unit
◆There must be no obstacles near the air inlet and outlet.
◆Install the indoor unit on a surface that can support its weight.
◆Choose a position that enables the piping and cables to be easily connected to the outdoor unit and the
recommended length of 7.5 metres to be respected.
◆Leave enough clearance beneath the indoor unit to enable the filters to be removed without hindrance.
◆Maintain sufficient clearance around the indoor unit, as indicated in the diagram on the page opposite.
◆Make sure that the water dripping from the drain hose runs away correctly and safely.
Outdoor Unit
◆The outdoor unit must NEVER be placed on its side or upside down, as the compressor lubrication oil will run into the
cooling circuit and seriously damage the unit.
◆Choose a location that is dry and sunny, but not exposed to direct sunlight or strong winds.
◆Do not block any passageways or thoroughfares.
◆Choose a location where the noise of the air conditioner when running and the discharged air do not disturb any
neighbours.
◆Choose a position that enables the piping and cables to be easily connected to the indoor unit and the recommended
length of 7.5 metres to be respected.
◆Install the outdoor unit on a flat, stable surface that can support its weight and does not generate any unnecessary
noise and vibration.
◆Position the outdoor unit so that the air flow is directed towards the outside, as indicated by the arrows on the top of
the unit.
◆Maintain sufficient clearance around the outdoor unit, as indicated in the diagram on the page opposite.
◆If the outdoor unit is installed at a height, ensure that its base is firmly fixed in position; the maximum height
is 7 metres.
◆Make sure that the water dripping from the drain hose runs away correctly and safely.
◆You have just purchased a multi-split type room air conditioner and it has been
installed by your installation specialist.
◆This device must be installed according to the national electrical rules.
◆Max input power & current is measured according to IEC standard and input power &
current is measured according to ISO standard.

Fixing the Installation Plate
Before fixing the installation plate to a wall or window frame, you
must determine the position of the 65 mm hole through which the
cable, piping and hose pass to connect the indoor unit up to the
outdoor unit. When facing the air conditioner in position on the wall,
the piping and cable can be connected from the:
◆Right
◆Left
◆Rear (right or left)
1Determine the position of the pipe and drain hose hole using the right
figure and drill the hole with an inner diameter of 65 mm so that it slants
slightly downwards.
2 If you are fixing the indoor unit to a... Then follow Steps...
Wall 3.
Window frame 4to 6.
3Fix the installation plate to the wall in a manner appropriate to the weight
of the indoor unit.
➢If you are mounting the plate on a concrete wall with anchor
bolts, the anchor bolts must not project by more than 20 mm.
4Determine the positions of the wooden uprights to be attached to the
window frame.
5Attach the wooden uprights to the window frame in a manner appropriate
to the weight of the indoor unit.
6Using tapped screws, attach the installation plate to the wooden uprights,
as illustrated in the last figure opposite.

Purging the Unit
On delivery, the indoor unit is loaded with an inert gas. All this gas
must therefore be purged before connecting the assembly piping.
To purge the inert gas, proceed as follows.
Unscrew the caps at the end of each pipe.
Result: All inert gas escapes from the indoor unit.
➢To prevent dirt or foreign objects from getting into the pipes
during installation, do NOT remove the caps completely
until you are ready to connect the piping.
Connecting the Assembly Cable
The outdoor unit is powered from the indoor unit via the assembly cable.
If the outdoor unit is more than 7.5 metres away from the indoor unit,
the cable must first be extended to a maximum of 15 metres.
1Extend the assembly cable if necessary.
2Open the front grille by pulling on the tabs on the lower right and left sides
of the indoor unit.
3Remove the screw securing the connector cover.
4When installing, remove the cables connected with A.
5Pass the assembly cable through the rear of the indoor unit and connect the
assembly cable such as figure.
➢Each wire is labelled with the corresponding terminal number.
6Pass the other end of the cable through the 65 mm hole in the wall.
7Replace the connector cover, carefully tightening the screw.
8Close the front grille.
9For further details on how to plug the other end of the assembly cable into
the outdoor unit, refer to pages 14 and 15.
