REMOTE CONDENSER UNITS:
ADVICE FOR INSTALLERS
A-The condenser unit, if air-cooled, must be installed
in a room with good air circulation. Otherwise, a
water-cooled unit should be used. In this case, the
water must be clean, delivered at a pressure between
1 and 10 bar and a maximum temperature of 15°C.
B-The oil return to the compressor must be
guaranteed. If the condenser unit is placed in a higher
siphon for every 2 m/6.4 feet of height difference.
C-For gaps of over 3m/10 feet or for distances over
10m/30 feet use the oil separator.
CAUTION: The oil separator retains a certain quantity
of oil. In systems preloaded with gas R404a oil has
already been entered, the other must be added during
the charging of the gas.
D-Clean the system thoroughly and create an
effective vacuum. This should ensure that the
quantity of air and (most importantly) the humidity
level within the system remain below the permitted
limits. A pressure level below 25 Pa is considered
as a vacuum.
E-After creating a vacuum, charge the gas, entering
the charge quantity in the relevant space on the
data plate.
F-Make sure that there are no gas leaks from the
welded/soldered areas.
