INSTALLATION OF THE INDOOR UNIT
- Mark the position of each supporting rod, cooling pipes,
drainpipe of condensates, wires of power supply and cable of
remote control .
The supporting rods can be fixed, depending on the type of
ceiling.
Various models to fix
- Fix the angle brackets provided with the unit, on the threaded
rods , we recommend Ø 6, max.Ø 8,
and keep them away from the ceiling at a distance of 270mm or
107mm .
GENERAL POINTS
BEFORE INSTALLATION
- It is recommended to place the indoor unit as close as possible
to its final location before unpacking.
- Avoid to lay heavy tools or weights on the packed unit.
Check as soon as the packing is opened, that no accessories
required for the installation, are missing. The grilled panel is
provided separately for better protection.
DO NOT LIFT THE UNIT BY GRASPING THE
DRAINPIPE OF CONDENSATES OR THE
COOLING CONNECTIONS, BUT ONLY THE
FOUR CORNERS.
CHOICE OF LOCATION
- Do not install the un it in rooms where inflammable gas or acid
or alkaline substances are present. Aluminium and copper
evaporators and/or plastic components inside could be
damaged.
- Do no install the unit in workshops or kitchens; oil vapours
attracted by treated air could settle on the evaporators of the
unit and change its performance or damage plastic parts inside.
- The indoor unit is flush mounted into a false ceiling, size of the
tiles 600x600 and multiple.
- Installation of the unit is made easier when using a fork-lift truck
and the base of the packing by placing the base between the
unit and the forks of the truck .
- It is recommended during installation to choose the location of
the unit as much as possible in the middle of the room, so as to
obtain the best distribution of treated air.
- Check that you can remove the discharge grilles and that the
clearance is large enough to allow maintenace and repairs.

Nut
- In case the brackets are assembled at the lower part, remove
the insulating foam around the fixing nuts .
The possibility to adjust the bracket at different heights leaves
the brackets free to fix them at the upper or lower part of the
cassette.
- Fixing the brackets at the lower part offers an easier assembly.
Do not tighten the nuts, nor the counter-nuts, this should only be
done after having made all connections and placed the unit in its
final horizontal position.
- Lift the unit (without the frame) carefully by picking it up at the
four corners.
- Place the unit in the false ceiling.
- To make the assembly easier the electrical box can be
disassembled by removing 2 screws, and disconnect the
multipoints connector (15 pts connector for the main connection)
and small connector for the infra-red.
- Fix the cassette, connect the multipoints connectors, place the
cassette into is final position and reset the electrical box with 2
screws
- Fix the screws to fix the corner irons .
- In case the false ceiling is 300 mm distant from the ceiling (mini-
mum height admitted) it may be necessary to remove
temporarily a few T-shaped rods from the false ceiling.
- Position the unit with a level and keep 10mm between the sheet
metal body and the false ceiling .
Angle bracket

T-shaped rod
- Position the unit on the supporting rods of the false ceiling by
first tightening the bolts on the side , then the nuts and counter-
nuts of the threaded rods . Finally place the rubber mount.
- Check once more that the unit is in a horizontal position after
connection of the condensate drain and the refrigeration
pipework.
DRAINING CONDENSATES
- To obtain correct condensate drainage , the slope downwards
should be 1 cm per meter without any bottleneck nor passage
upwards . Furthermore a trap of at least 50 mm high should be
mounted to avoid bad smells in the room.
- Install an auxiliary pump to drain condensates and a levelcontroller
if the condensates are to be drained at a higher level than the
unit. It is recommended to install an appliance equipped with a
safety floater to stop the compressor in case the auxiliary pump
is damaged.
- The drainpipe of condensates should be heat insulated with
insulating material 5 to 10 mm thick, such as polyurethane,
propylane or neoprene, avoiding condensation.
- If several units are placed in the room , the draining system can
be made as indicated above.

REFRIGERANT LINES AND
CONNECTIONS
CAUTION
- On K 45 RCFA, the expansion kit is installed, to the indoor unit,
on the liquid line.
- The cassettes are designed to be connected to the outdoor
units using flare lines (refrigerant grade copper pipe fitted at
both ends with flare nuts and insulated over the full length).
PIPE PREPARATION
- Use refrigerant grade copper pipe with a diameter suited to
each model (see page 4).
- The gas pipe and liquid pipe must mandatorily be covered with
insulating material at least 6 mm thick.
- Fit the flare nuts on the ends of the pipes before flaring the
pipes.
- The separately insulated pipes and their fittings can then be
attached to the condensate drain and power cables with a clamp.
INSTALLATION OF REFRIGERANT
LINES
- Drill an 80 mm diameter hole through the wall for the crossing of
the lines between the outdoor unit and indoor unit .
INSTALLATION OF THE OUTDOOR
UNIT
- Minimum clearance to respect (in mm).
- Avoid recycling the air, even partially, between the air inlet and
discharge.
INSTALLATION ON THE FLOOR
- The outdoor unit is supposed to be fixed directly on the floor: 4
holes Ø 10 (see dimensional drawing).
- Waffle pad can also be placed under the feet to absorb vibra-
tion.

ROUTING OF THE PIPES
- The pipe bending radius must be greater than or equal to 3.5
times the pipe diameter.
- Do not bend the pipes more than three times in a row and do
not make more than 12 bends in the total length of the line.
- If the suction pipe has a vertical section more than 8 meters in
length, it is MANDATORY to provide a trap every 3 meters when
the outdoor unit is installed above K 30 RCF .
EVACUATION OF REFRIGER-
ANT LINES AND INDOOR UNIT
- The R22 charge is contained only in the outdoor unit. The indoor
unit contains a small amount of neutral gas. That is why it is
necessary to evacuate the lines and indoor unit after installing
the lines.The outdoor unit has a valve used for evacuating the
system (large valve).
INSTALLATION PROCEDURE
- The outdoor unit a valve (large valve) used for evacuating the
complete system.
1 Connect the pipes of the line to the outdoor unit and indoor unit.
- Cover the surface with refrigerant oil to tighten the fittings
correctly.
- Always use a counterwrench to tighten the valves .

2 Connect the vacuum pump to the flare coupling of the outdoor
unit fitted with the large service valve (large coupling).
3 Turn on the vacuum pump and check that the dial pointer drops
to -0.1 MPa (-76 cm Hg).
The pump should remain in operation for at least 15 minutes.
4 Before removing the vacuum pump, check that the vacuum dial
remains stable for five minutes.
5 Disconnect the vacuum pump and reclose the service valve.
6 Remove the caps from the GAS and LIQUID valves and open
them with a socket wrench to release the R22 contained in the
outdoor unit.
7 It may be necessary to adjust the charge according to the
length of the line and the processing unit (see pages 5 and 6 to
calculate the charge to be added). Put the caps back.
8 Check the lines for leaks using an electronic leak tester or a
sponge soaked with sudsy water.
CHARGE ADJUSTMENT
- This operation must only be carried out by qualified personnel
in accordance with the rules of good workmanship in
refrigeration. The extra charge is added through the service
valve of the outdoor unit flare coupling (large coupling).
FINAL TASKS
- Check that the valve caps are correctly tightened.
- Attach the cables and lines to the wall with clamps if necessary.
- The additional capillary (identified by a red tag) should only be
used above 8 meters.
- Below 8 meters, it can adversely affect the heating power (winter
mode) and compressor oil temperature and should not be left
in service. Pinch it as shown on the red tag.
- Capillary before pinching:

hot water or steam, as this could cause the pressure of the
coolant to increase.
Check that the surface of the aluminium fins of the heat exchanger
is not damaged by impacts or scratches, and clean with an
appropriate tool if necessary.

In order for the installation to operate correctly, it is essential to
regularly clean the air filter located in the intake of the indoor unit.
When clogged, the filter reduces the air flow through the heat
exchanger of the indoor unit, which in turn reduces the efficiency
of the installation and inhibits the cooling of the fan motor.
Check the cleanness of the indoor heat exchanger.
