You are able to incorporate option elements such as electrical heater in units 007 to 020.

CABINET

The cabinet is made of unpainted galvanised steel. Thanks to its
compact dimensions, and to its technical features, the unit can
be positioned in almost any location. Thermal-acoustic insulation
in compressor area to reduce noise level.

Units 002-003: 10 mm (M1) insulation in air section.
Units 007-020: 25 mm A2, S1, D0 (M0) in the air treatment

section.

FOR ELECTRICAL CONNECTION REFER TO WIRING DIAGRAM IN THE UNIT.

INSTALLATION GUIDE FOR CONTROL CABLE (TO A VOID INTERFERENCES

):

• Use the screened 15 m cable supplied with terminal (3 wires + screen).

• Wire the cable separated from electrical power wiring by a physical distance of 500 mm.

• Wire the cable separated from halogen lamps/fl uorescent tube lighting... by a phyisical distance of 500 mm.

• Wire the cable separated from radio frequency sources such as radio transmitter... at least 500 mm.

NEVER WIND THE REMAINING CABLE AROUND, CUT THE CABLE BY THE TERMINAL END.
