General description

The units in the SOC range are the outdoor units of a split-
type air conditioner; they are fitted with a vertical discharge
axial fan and have been designed for installation outdoors.
Units SOC-076 to 180 are compatible with indoor units
SIC-076 to 60. In winter they can provide heat if the indoor
unit SIC is fitted with an electric heater or a hot water coil
(optional accessories).
The outdoor unit SOC-240 is compatible with the SIC-240.
For operation, these units must be connected, electrically
and with regard to the refrigerant, to the corresponding indoor
unit.

Design level
oversized mechanical components and a low-consumption
motor.
It is delivered with a charge of special oil which prevents the
formation of foam, and with an oil heater element.
Models SOC-090 and SOC-180 incorporate Scroll rotary
compressors. Remaining models incorporate reciprocating
compressors.
Compressor heater
Keeps the crankcase oil hot to ease start-ups and prevent oil
from being carried away from the compressor.
Coils
Large heat transfer area coils, made of copper tubes and 'slit'
aluminium fins.
Fans
Axial fans with free air discharge, without ductwork. Quiet
operation and three speeds available.
Casing
Made of aluminium-zinc galvanized steel sheet, finished with
baked-on polymerized powder paint.
Refrigerant circuit
Made of brazed copper tubes.
Units are delivered dehydrated and after having passed the
relevant pressure and leak detection tests.
Electrical and control wiring system
Highly reliable integrated circuits. Their compact size permit
easy and fast servicing. It complies with the European
regulations currently in force.
Mechanical specifications of indoor unit SIC-
240
Indoor unit SIC-240 is compatible with either of the cool only
outdoor units SOC-240 or heat pump SOH-240.
The main features of this unit are as follows:
Fan
Double fan type with common shaft, pulley and belt
drive. The fan pulley is of the removable tapered core ty-
pe.
The motor is mounted on a tensioner base which makes
maintenance operations easier.
The fan motor assembly is resiliently mounted on spring
isolators to avoid tranmission of vibration and noes.
Coil
Made of copper tubes and aluminium 'slit' fins.
Control box
Fully accessible from outside.
Casing
Made of aluminium-zinc galvanized steel sheet highly resist-
ant to corrosion, painted with baked-on epoxy-polyester
powder enamel.
It features a shape framework which allows for all its compo-
nents to be easily accessible.
It can take up an electric heater (optional accessory).
With integral filter rack and air filter.
Refrigerant circuit
Double circuit with directional connections and calibrated
orifice type.
