Technical specifications
Mechanical specifications
Compressor
Of the vertical hermetic type "Scroll", mounted on shock
absorbers and with internal motor protection and an electric
heater for heating the oil.
Coils
Made of copper tubing and aluminium fins. Located within
the cabinet and completely protected against damage during
transportation or installation.
Indoor and outdoor fans
Of the centrifugal type with directly fitted motor or belt drive.
These fans have sufficient available pressure for the instal-
lation of optional ducts and accessories.
Casing
Made of galvanized steel sheeting and finished with oven-
polymerized powdered paint. This allows installing outdoors.
Internally, in the evaporating unit area, it is coated with insula-
tion to avoid condensation. These units include a galvanized
sheeting tray with corresponding drain for collection of con-
densates from the evaporating coil.
Cooling circuit
Made of welded copper tubing. All units are supplied with
a corresponding optimized refrigerant charge and having
surpassed the maximum pressure and leak-tightness tests.
Refrigerant expansion, which takes place in the internal sec-
tion, is carried out by means of a calibrated and distributed
hole in 07L, 10L and 15L sizes, and with expansion valve
and distributor in 20L, 25L and 30L. The circuit includes:
high and low pressure switches and suction and discharge
pressure intakes.
Refrigerant
These units are manufactured with R-410A.
Electric panel
Accessible directly from the outside. Includes connecting
strip, protectors, electronic board and probes, power supply
contactors, operating relay, phase control relay and trans-
former. In compliance with European regulations currently
in force.
Phase control relay
The electric panel of the unit RTC20L, 25L and 30L intro-
duces 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 contact, disconnects power supply to the
main board of the unit, leaving it inoperative.
Electric heater (optional)
Of the exposed wire type to allow fast heat dispersion, avoid-
ing temperature inertia that could affect the components.
Equipped with a contactor and thermal protectors: automatic
and manual reset.
Thermostat
The RTC07L to 30L units include, as standard equipment,
the electromechanical DPC-1 thermostat.
To connect the thermostat to the board, 10x0.22mm
2
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.
It allows selecting different set point temperatures for cool
General information
General description
The RTC model air conditioners are packaged type compact
horizontal units, condensed by air.
They can be installed either indoors or outdoors, and the
fans are of the centrifugal type, and therefore accept ducts
for channelling air.
Nomenclature
Compact horizontal air
conditioning unit RTC.
