and the inlet grille (4) can be removed beforehand. To do this,
undo the clips (A) by turning them a quarter of a turn using a
screwdriver or a coin.
IMPORTANT : When refitting the grilles, take care to lock the clips
(A) by turning them a quarter of a turn.
3.1.2 - REMOVING THE FAN ASSEMBLY
• Remove the fastening screws.
• Disconnect the loom at connector (D).
• Pull the fan assembly.
3.1.3 - CHOOSING THE LOCATION
AVOID:

rooms (IP 20).
• Direct exposure to sunlight or the proximity of heat sources.
• Installing the unit behind curtains or furniture which could prevent air circulation.
• Installing the device near inflammable materials (as it can be equipped with an
electric heater).
MAKE SURE THAT:
• The position is the best one for providing good ventilation in the room.
• That the solidity of the support is adequate for the weight of the unit and does not
cause vibrations.
0.30m
1 m
D
• The position chosen complies with the recommended minimum maintenance spaces (see drawing opposite), and that the
distance and difference in level between the units are as small as possible.

APPLIANCES FILLED WITH R 407 C
R 407 C
• Fluid R 407 C, as opposed to R22, is not a pure fluid
but a blend composed of:
- 23% R 32 + 25% R 125 + 52% R 134 A.
• The compressors approved for operation with this
fluid are filled beforehand with polyalcohol oil.
Contrary to mineral oil, it is very hygroscopic: it
absorbs the humidity of the ambient air very quickly.
This can modify its lubricant properties and lead in
time to the destruction of the compressor.
MAINTENANCE INSTRUCTIONS
1 - Never add oil to the appliance; the compressor is
filled with polyalcohol oil, a special oil which cannot
tolerate the presence of other oils.
2 - The instruments used for:
- filling,
- pressure measurements,
- emptying under vacuum,
- recovering the fluid,
must be compatible and only used for the R 407 C
fluid.
3 - The weight of the refrigerant contained in the
storage bottle must be checked constantly. Do not
use it from the moment the remaining weight is less
than 10% of the total weight.
4 - In the case of a new charge:
- do not use the charging cylinder,
- use a balance and a dip pipe type R 407 C cylinder,
- charge the weight of R 407 C as per the value
indicated on the unit’s identification plate (for “split
systems”, refer to the installation instructions as the
charge must consider the length of the connecting
lines),
- IMPORTANT: see paragraph 3.
5 - The charge must be undertaken in liquid phase.
6 -
In case of leakage, do not complete the charge:
recover the remaining refrigerant for recycling and
perform a total charge.
Recovery, recycling or the destruction of the fluid must
be done in compliance with the laws in force in the
country concerned.
7 -
If the refrigerant circuit is opened, you must
:
- avoid the entry of air into the circuit as much as
possible,
- replace the filter drier,
- perform the “vacuum operation” at a minimum level
of 0.3 mbar (static).

5.5.1 - MONTAGE / INSTALLATION
• See the main characteristics in the Technical Instructions.
• Consult the "Installation instructions" supplied with the control.
• The unit is connected using 0.75mm
2
cable (minimum) (1.5mm2 max.).
The cables used must comply with the insulation requirements for the voltage used (230V).
This information relates above all to the sensor input of the automatic control connected to the 230V supply.
• The temperature adjustment range can be limited by means of the mechanical limit stops located on the control knob.
• Wall mounting:
- Secure the unit at a height of approximately 1.5 m from the floor in a location representative of normal convection
currents, while avoiding:
- wall which are poorly insulated or liable to vibrate,
- the proximity of parasitic heat sources (sunshine, heating appliances, lamps, fireplaces, televisions, etc.),
- currents of air from doors or windows,
- sheltered locations such as shelves or behind curtains,
- near electrical outlets.
- For manual control K 60 D 076 Z, check and modify as required the ventilation selection jumper connection SR
depending on the appliance (see below).
- For the K 60 D 025 Z automatic control, if necessary, adjust the neutral zone using the potentiometer located inside
the control.
• Caution:
If a remote control is used, remove the wire between terminal L1 and switch S1 on the air processor terminal
board.

- that the unit is connected to earth.
- that no tools or any other objects have been left in the units.
- that the filter is correctly fitted.
- that the condensate discharge outlet is correctly connected.
8.2 - SWITCH ON THE UNIT
• Using the isolation and protection device.
