4.1 - CONNECTION OF THE CONDENSATE LINES
4.1.1 - VERTICAL MOUNTING
•Use the 12 mm dia. x 16 mm hose supplied.
•Pass it with refrigerant pipes through one of the covers and connect it to
a pipe of minimum internal diameter 12 mm, respecting a slope in the
liquid's flow direction.
4.1.2 - CEILING MOUNTING
• Use the copper pipe and the end piece supplied.
4.2 - REFRIGERANT CONNECTION
•If the difference in level is greater than 3 metres,
make an oil trap.
NOTE: Nominal cooling capacity is given for a total
pipe length of 8 m.
For pipe lengths over the maximum length, please
consult us.

APPLIANCES FILLED WITH R 407 C
R 407 C
•FluidR 407 C,as opposedto R22,is nota purefluid 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.
Contraryto mineraloil, itis veryhygroscopic: itabsorbs
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,
mustbecompatible and onlyusedfor theR407 Cfluid.
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,
-chargetheweight ofR407C asperthe valueindicated
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).
