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.
Fan coil units are shipped in individual cartons.
Never store or transport the unit upside down. Do not stand or transport the machines on end. For storing, each
carton is marked with "up" arrows. 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
The unit is not designed to withstand weights or stresses from adjacent equipment, pipe work or
constructions. Any foreign weight or stress on the unit structure could lead to a malfunction or a
collapse with dangerous consequences for personnel and property. In such an event, the warranty
shall be null and void.
CLEARANCE
The unit base shall be arranged as indicated in the manual. There could be a risk of personal injury
or damage to property in the event of the unit being incorrectly supported.
The unit must be installed on a firm level foundation, of adequate strength to support its full operating weight.
It must be high enough to permit good drainage of defrost water with syphon
When locating unit give consideration to, and locate unit as remote as possible minimise noise, as
heat pump loads are greatest at night time.
The unit must be pitched slightly towards condensate drain outlet to provide positive drainage of
condensates.
All electrical and ductwork connections to the unit must be made via flexible connections to prevent
transmission of vibration.
In addition to the service clearances noted on the dimension sheet it is essential that provision is
made for adequate and safe service access.

UNIT LOCATION
Fan coil units are designed to be installed in a controlled environment. Each unit should be located on the
installation plans. Inspect the carton for specific tagging numbers and references (models, size, left hand or right
hand). The supply, return and condensation piping should be located accordingly making sure the piping will fit
into the confines of the fan coil chassis and cabinet.
Note: on the fan coil units with cabinet AWC or AHC, the cabinet is out of line in comparison with the unit chassis.
Provide sufficient space to make water and electrical connections.
Important notes :
Inspect the fan coil unit nameplate sticked on the back of the unit chassis.
AWN / AWC console units are to be installed vertically against a wall or on a floor using support
feet.
Only AHN / AHC ceiling units are designed for ceiling mounting.
After installing the unit, please be sure that there is no more longitudinal and transversal counterslopes
avoiding condensate evacuation.

UNIT INSTALLATION
AWN / AWC CONSOLE UNIT
All units are to be installed against a wall as a floor console with support feet, or wall mounting as per dimensional
data. On the fan coil units equipped with support feet, we recommend you to fix the unit to the wall through the
both oblong holes located on the upper part of the unit chassis.
On the AWC model, to hang the unit to the wall, it is necessary to remove the cabinet.
Drill holes on the wall in accordance to the dimensions mentioned. Install the fixing screws (contractor supply).
Place the chassis unit over the fixing screws through the oblong holes and screw it directly to the wall.
Ensure adequate space for pipings and electrical connection, and check side of connection.

AHN / AHC CEILING UNIT
The AHN / AHC units are designed for ceiling mounting. Recommended fixing by M8 threaded rod or 8 mm
diameter anchor bolts (contractor supply).
When the AHN units are ducted at the inlet side, the controller return sensor must be located outside the fan
compartment in order to ensure its good operation.
For the AHC model with cabinet, it is necessary to remove the cabinet before installing it.
Follow instructions for cabinet removal.
Drill holes in the ceiling in accordance with dimensions mentioned. Install the fixing screws (contractor supply).
Place the chassis unit on the fixing points and screw it directly to the ceiling, or to the veritable support.
The fan coil unit should be pitched towards the drain side, to facilitate condensate evacuation.
Recommended fixing by M8 threaded rod with H8
hexagonal nut or 8 mm diameter anchor.

CONDENSATE DRAIN LINE
CABINET REMOVAL
When removing cabinet do not pull or lift it up by the discharge grilles, to avoid
any damages on articulated fasteners of the access doors.
After installing the unit, be sure that there is no more longitudinal and transversal
counterslopes avoiding condensate evacuation.
For that, use a square and spirit level to make sure that fan coil unit is level and that it is at a 90 degree angle
between the wall and floor (see fluorescent sticker on unit chassis).
Note : If the floor and the wall are not at right angle, it may be necessary to shim the fan coil unit to insure proper
installation. Manufacturer will not accept any responsability on units not being on proper level.
Each fan coil unit is supplied with a 16 mm ID condensate S-shaped pipe. The drain pipe extends approximately
60 mm out of the piping compartment, to ensure either floor or wall connection to the main drain piping.
For the special case of a horizontal encased AHC unit, you must follow the connections as shown below:
On the AWC and AHC models, to hang the unit to the wall, it is necessary to remove the cabinet.
To achieve this:
Remove the fastener screws from the access hatch situated at the right end of the
unit, on the electrical connections side.
Withdraw the four screws that hold the casing attached to the two chassis
flanks.
Then, lift the casing vertically by pulling its forwards. Place it
carefully to one side.
