GENERAL RECOMMENDATIONS
Please read the following safety precautions very carefully before installing the unit.
SAFETY DIRECTIONS
Follow the safety rules in forces when you are working on your appliance.
The installation, commissioning and maintenance of these units should be performed by qualified personnel having
a good knowledge of standards and local regulations, as well as experience of this type of equipment.
The unit should be handled using lifting and handling equipment appropriate to the unit's size and weight.
Any wiring produced on site must comply with the corresponding national electrical regulations.
Make sure that the power supply and its frequency are adapted to the required electric current of operation, taking
into account specific conditions of the location and the current required for any other appliance connected with
the same circuit.
The unit must be EARTHED to avoid any risks caused by insulation defects.
It is forbidden to start any work on the electrical components if water or high humidity is present on the installation
site.
WARNING
Cutoff power supply before starting to work on the appliance.
When making the hydraulic connections, ensure that no impurities are introduced into the pipe work.
The manufacturer declines any responsibility and the warrantly becomes void if these instructions
are not respected.
If you meet a problem, please call the Technical Department of your area.
If possible, assemble the compulsory or optional accessories before placing the appliance on its final location. (see
instructions provided with each accessory).
In order to become fully familiar with the appliance, we suggest to read also our Technical Instructions.
-The informations contained in these Instructions are subject to modification without advance notice.

INSPECTION AND STORAGE
At the time of receiving the equipment carefully cross check all the elements against the shipping documents in
order to ensure that all the crates and boxes have been received. Inspect all the units for any visible or hidden
damage.
In the event of shipping damage, write precise details of the damage on the shipper’s delivery note
and send immediately a registered letter to the shipper within 48 hours, clearly stating the damage
caused. Forward a copy of this letter to the manufacturer or their representative.
Never store or transport the unit upside down. It must be stored indoors, completely protected from rain, snow etc.
The unit must not be damaged by changes in the weather (high and low temperatures). Excessively high temperatures
(above 60 °C) can harm certain plastic materials and cause permanent damage. Moreover, the performance of
certain electrical or electronic components can be impaired.

INSTALLATION
LOCATION OF THE INDOOR UNIT
Select a location taking into account the following points:
The indoor units (ST) can be installed in 2 different rooms. The INDOOR UNIT should not be installed
in a bathroom or a laundry.
The location should be well aired without any object or piece of furniture standing in the way; the
air should circulate freely.
Do not place the appliance close to a heatsource, do not expose it directly to sunrays.
The location should allow easy connection of the power supply, of the cooling pipes and condensate
drain.
The unit should be mounted on a wall sturdy enough to withstand the weight of the appliance.
The panel of assembly should be installed as shown in the diagram below.






INSTALLATION OF THE ASSEMBLY PANEL
Place the assembly panel horizontally on the wall, as shown, by means of a bubble level .
Mark the position of the four holes of the panel on the wall and drill these holes to be filled with pegs.
Assemble the panel on the wall with the four screws. Tighten the screws.

BORING THE WALL FOR PASSAGE OF THE HYDRAULIC PIPES
Mark the position of the hole at each side of the assembly panel as shown on the diagram, next drill these holes
under an angle of 5° downwards.
The hole downwards allows to avoid condensates or rain to enter inside.
Place a standard plastic tube Ø 70 mm in the hole.
One can also run the hydraulic connections in a chute again the wall. To do this, enlarge the pre-recessed part of the
plastic bottom in order to the able to position the inlet and outlet hoses as well as the condensate drainage line.
ASSEMBLY AND REMOVAL OF THE APPLIANCE FROM THE ASSEMBLY PANEL
See to it that the hydraulic links (insulated with 9mm thickness in the case of elastomer line, and 13mm in the case
of copper line), the electric cables and the drainpipe are insulated by means of an appropriate tube ("Armaflex"
type, 5 mm thickness); they should be covered all together with a plastic, non-adhesive strip, and passed through
the hole of the wall.
Hang the indoor unit on the 2 hooks located close to the upper edge of the assembly panel. Press the lower part
of the indoor unit against the assembly panel until the latches interlock in the slots and lock the indoor unit on the
assembly panel. Check that the unit is well locked on the panel by pulling the unit.
In order to remove the unit from the mounting plate, raise and pull outwar.
Make sure that the hooks are locked.

Place the pipe against the hydraulic pipes and the electric cables.
Check that the drainpipe is running downwards.
Avoid siphons and bends when installing the drainpipe.
The end of the pipe should be under waterlevel.
For an outlet at the left, lay the drainpipe in the seat at the rear of the unit .
If the location selected requires to use long horizontal sections of the drainpipe, provide for an opening at the top
of the pipe to avoid overflow of the condensing tray.
After having finished the installation, test the draining by pouring at least two liters of water into the condensing
tray. Check that water is freely being drained.

MAINTENANCE AND REPAIRS SHOULD BE CARRIED OUT BY QUALIFIED
SPECIALISTS
Before carrying out any servicing operations, check that the air conditioner is disconnected.
In order to remove the air filter, lift the front panel, push the filter slightly upward in order to unlock them.
DO NOT OPERATE THE AIR CONDITIONER WITHOUT THE FILTER!
Note :The filter should be cleaned at least once a month.
CLEARING THE AIR CONDITIONER
Rub the indoor unit with a soft, dry cloth or else clean it with a vacuum cleaner.
Do not use hot water or volatile detergent products which may damage the outside of the air conditioner.
PRECAUTIONARY MEASURES TO BE TAKEN AT THE BEGINNING OF THE SEASON
Check that there are no obstacles to the air which is sucked in and blown out, on both the indoor and outdoor
units.
Check that the air conditioner is properly connected.
We recommend that the appliance be maintained by qualified specialists (cleaning the turbine, condensates tray,
etc...)

USE
Two modes available:
Cooling
Heating
Auto
For each of these modes, fan ventilation can be configured in LS, MS, HS and Auto Ventilation modes.
For certain conditions of use, a 5 minute time delay is required at start up. During these 5 minutes, the remote
control is inoperative.
