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 (-
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 (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 R407C into the atmosphere).

ELECTRIC CONNECTIONS
POWER SUPPLY
The power supply is connected with the outdoor unit
(except DS 16).
This appliance is meant to be permanently connected
with a fixed cable.
See the electric diagrams on the appliance
(Fig. 21
a, b and c).
The connection is made with the outdoor unit after
removal of panel A (Fig.13).
AIR SUCTION 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 suction 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 COMPLIANCE WITH THESE INSTRUCTIONS
WILL CAUSE CONDENSATE
TO DRIP
CHECKING BEFORE STARTING
OPERATION
