The values of the tightening torque are shown in the
table below.
2 - Connect the vacuum pump with the flare coupling of
the outdoor unit equipped with a process valve (large
coupling).
3 - Start the vacuum pump and check that the needle of
the indicator goes down to -0,1 Mpa (-
76
cm Hg).
The pump should run during at least 15 minutes.
4 - Before disconnecting the vacuum pump, check that
the vacuum indicator remains in the same position during
five minutes.
5 - Disconnect the vacuum pump and close the process
valve.
6 - Remove the cap of the "GAS" and "LIQUID" valves and
open them with a hexagonal wrench to free the
R407C
contained in the outdoor unit. Put the caps back.
7 - Check that the linking pipes are sealed. Use an
electronic leak detector or a soapy sponge.
ADJUSTMENT OF THE CHARGE
Adjustment of the charge may be needed depending on
the length of the linking pipes and on the indoor unit.
This operation should be done expertly by qualified
personnel and (regrigeration engineer). The additional
charge is to be added through the process valve of the
flare coupling of the outdooor unit (large coupling).
Any action on the cooling circuits requires to comply with
the CECOMAF GT1-001 recommendations. (related to
the discharge of R
407C
into the atmosphere).

Lengths upon request from 9 to 15 meters (extension
possible up to 25 meters on site).
- the pipes are supplied rolled up and equipped with flare
nuts (Fig.
17
).
- Unroll the pipes carefully in the directon opposite to
the spires to avoid folding (Fig.
10
).
ELECTRIC CONNECTIONS
POWER SUPPLY
The power supply is connected with the outdoor unit
(except
BS
11).
This appliance is meant to be permanently connected
with a fixed cable.
See the electric diagrams on the appliance
(Fig. 21
a, b, c and d).
The connection is made with the outdoor unit after
removal of panel A (Fig.13).
AIR SUCCION AND DISTRIBUTION
SEE ACCESSORIES page 6 and see last page
of these instructions.
AIR RENEWAL
- Lateral ports allow to install separated ducts for fresh
air succion and discarge in a neighbouring room.
- Remove the anti-condensation insulation and the
prepunched sheet metal of the ports by using a piercer:
BE CAREFUL not to damage the heat exchanger
located at the rear.
- Fill the space between the ducts and the edge of the
ports with anti-condensation insulation. Use materials
resisting at a temperature of 60°C when the appliance
is in continuous operation.
- The ducts can be flexible with a spring core or a core of
corrugated aluminum, insulated at the outside
(glassfibers 12 to 25 mm thick).
- When the installation is finished all duct surfaces should
be anti-condensation insulated (expanded
polystyrene,expanded neoprene, 6 mm thick).
NON RESPECT OF THESE INSTRUCTIONS
WILL CAUSE CONDENSATES
FLOWING DOWN
TREATED AIR DISCHARGE IN A
NEIGHBOURING ROOM
- Discharging air in a neighbouring room requires to close
one or two discharge louvers corresponding with the
ducts.
- A decompression grille should be installed on the wall
between the air conditioned room (where the air
treatment unit is located) and the neighbouring room
(Fig. 18).
CHECKING
BEFORE
STARTING
OPERATION
POWER SUPPLY VOLTAGE
The voltage and frequency of the power supply of the
appliance should be in conformity with the values
indicated on the identity plates of the indoor and outdoor
unit.
