Technical specifications
Mechanical specifications
Compressor
Vertical hermetic alternative type, mounted on antivibratory
supports, specially designed for heat pump units with oversiz-
ing of mechanical components and low consumption motor.
The SCOH-070K, 076K, 090K and 120K units have one
compressor, while the SCOH-150K, 180K, 240K and 300K
units have two compressors.
Supplied with a charge of special oil so as to avoid foaming.
With oil electric heater.
Compressor heater
Keeps the sump oil hot for easy start-up and avoiding oil
being dragged out of the compressor.
Suction accumulator
Fitted in the suction tubing of the compressor, it protects same
from slugging by avoiding oil leaving the compressor.
Coils
Of a large surface, made of grooved copper tubing and alu-
minium fins. Located inside the cabinet, and thus protected
against damage during transportation or installation.
Indoor fan (SICH-070 and 076B)
A centrifugal fan driven by an independent motor and belt
drive is installed.
Indoor fan (SICH-090, 120, 150, 180, 240 and 300B) and
outdoor fan (SCOH-070, 076, 090 and 120K)
Two centrifugal fans with a common shaft and belt drive,
driven by one single motor and coupled to the single plenum,
are installed.
Outdoor fan (SCOH-150, 180, 240 and 300K)
Two independent centrifugal fans are installed. Each one of
these is driven by an independent motor and coupled to the
single plenum.
Transmission from the motor to the fan is by belt drive.
These fans have sufficient available pressure for the instal-
lation of ducts and optional accessories.
Cooling circuit
Made of welded copper tubing and equipped with access
connections on the high and low pressure sides.
Refrigerant
The SCOH and SICH units are supplied with connections
ready for welding. The refrigerant load should be carried out
completely on job site. See refrigerant loads in physical data
table. The refrigerant used is R-407C.
Electric panel
Accesible directly from the outside. Includes connecting strip,
protectors, electronic board and probes, power supply con-
tactors, operating relay, phase control relay and transformer.
In compliance with European regulations currently in force.
Phase control relay
The electric panel of the unit introduces a sequence and
phase failure detector. In the case of detecting a phase
sequence other than R-S-T, or a phase fails once the unit is
in operation, this detector, by means of an internal volt-free

General information
General description
The SCOH/SICH heat pump models are air-air units with cen-
trifugal fans both in the indoor as well as the outdoor units.
The SCOH outdoor unit includes compressor, condensing
unit, centrifugal fan and controls. The SICH indoor units in-
clude evaporating coil, filter and fan. If necessary, they can
be easily modified on job site so as to have a compact unit.
The outdoor unit can be installed either outdoors or indoors,
as it is protected to withstand outdoor conditions, while the
fans are of the centrifugal type and can accept ducts.
Supplied complete, factory tested and ready for installation
of either interior or duct electric heaters accessories.
Designed to achieve considerable savings in energy and a
long service life.
Start-up and automatic regulation of the temperature is car-
ried out by means of a 24-volt ambient thermostat.

contact, disconnects power supply to the main board of the
unit, leaving it inoperative.
Shoud the phase sequence be correct and the centrifugal
fan of the indoor unit (BCVI) rotates in the wrong direction,
interchange two phases at the bottom of the fan contactor.
Dryer filter
Coupled to the cooling circuit to protect the refrigerant against
humidity.
Casing
Made of zinc-aluminium plated steel sheeting, primed and
enamelled in epoxy power for outdoor installation.
Complementary heaters
Of the open-air wire type for fast heat dissipation, avoiding
temperature inertia that could affect components.
Operating diagram
Thermostat
The SCOH/SICH-070 to 300 units include, as standard equip-
ment, the electromechanical DPC-1 thermostat.
To connect the thermostat to the board, 10x0.22mm2
screened communication cable should be used.
Ambient thermostat DPC-1
Programmable digital thermostat with communication
This thermostat was designed to give close control of the
ambient temperature and graphic information regarding
the mode it is currently operating in. This control unit, in
accordance with the differential between the programmed
temperature and the ambient temperature, responds varying
the on/off cycles.
The liquid crystal display (LCD) normally indicates the ambi-
ent temperature, operating mode and whether the system is
in heat or cool.

Limits of use
Notes: WB = wet bulb. DB = dry bulb.
(1) Below -20°C, only the emergency electric heater (optional) remains operative.
(2) This equipment can operate, for a short period of time, at temperatures below 10°C so as to raise the temperature of the conditioned space to
10°C.
