B.3.1 Positioning
Place the condensing unit in a well-ventilated room away
from heat sources.
If the remote unit is installed outdoors, it must be protected
against the atmospheric agents with adequate covering, in
any case ensuring correct ventilation of the condensing unit.
Connect the copper pipes, making sure to choose the shortest
path and with minimum use of curves and vertical sections.
To obtain optimum appliance performance:
in horizontal sections, the inlet line must slope down towards
the condensing unit at an angle of not less than 2%;
traps must be installed before all upward sections of the
inlet line;
insulate the inlet line with suitable lagging;
install a suitably sized dehydration lter, a liquid ow indi-
cator and a solenoid valve on the delivery line, in the order
indicated.
ATTENTION
Pay particular attention
to positioning of the pipes
for the remote connection
of the equipment; avoid
making them pass direct-
ly above the roof of the
evaporator, as shown in
the gure:
The upper left side has holes for the passage and xing
of the pipes for rear remote connection (gure below):
B.3.2 Customer's responsibility
The refrigerant charge must be R134a type for refrigerated
models and R404A for freezer models (depending on the
type of valve tted).
In any case refer to the data given on the rating plate.
B.3.3 Electrical connection
The condensing unit power is supplied by the equipment it
is connected to. For the electrical connection, carefully follow
the instructions in par. B.2.8.
ATTENTION
Appliances arranged for
connection to the remote
unit have an anchoring
device for connecting the
connection cable to the ex-
ternal unit.
