1. GENERAL CHARACTERISTICS
FANS
The fans of the indoor and outdoor sections are of EC Plug
Fan type. The fans are regulated automatically to obtain a
variable air volume in indoor and outdoor unit.
Optional: Fan with metal blades, for outdoor and indoor
units size 020.
REFRIGERANT CIRCUIT
Made with dehydrated copper tubes welded with pressure
sockets with a shutter valve on the suction and unloading
lines, in outdoor and indoor section. The unit incorporates
a high-pressure minipresostat and high-pressure and low-
pressure transducers. It incorporates dehydrator lter, ex-
pansion system with electronic valves, one in the package
units and two in the split units. The units in heat pump
incorporate suction accumulator to avoid the migration of
liquid to the compressor, reversible valve for inversion cy-
cle and unidirectional valves. The split units also include
an oil separator.
EXCHANGERS
Manufactured with copper tubes and corrugated or lour-
vered aluminum ns, designed to get high heat transfer.
Their dimensions and design of the circuits have been
specially studied to obtain the maximum performance of
the exchangers, increasing the capacity of the unit and
reducing the consumption.
ELECTRICAL CIRCUIT
Designed according to standard EN-60204-1. With ther-
mal protection magnets for compressors and fans. All
compressor and fan motors incorporate internal thermal
protectors. An electronic control governs the operation of
the unit, manages the “driver“ of the compressor, the fans
EC Plug Fan and the electronic expansion valves.
1.2. GENERAL DESCRIPTION
CASING
Galvanized and painted sheetmetal casing. The units in-
corporate metal supports attached to the base, for its cor-
rect handling and hoisting. These supports allow to install
the unit on the oor or hanging from the ceiling, providing
great rigidity to the installation of the unit. The panels are
easily interchangeable allowing several alternatives of im-
pulsion and return air. The outdoor and indoor sections are
insulated thermally and acoustically. In the indoor units,
an insulation with aluminum mesh protection with M1 and
F1 classication is used, certifying that this material is
self-extinguishing in case of re, avoiding the formation of
fumes that could enter the premises to be conditioned. In
the outdoor units, insulation with M1 classication is used.
MAIN SWITCH
Located in the access panel to the electrical board and
equipped with a mechanism which only allows the open-
ing of the panel of the electrical board when the switch is
OFF position.
INDOOR - OUTDOOR UNIT
INTERCONNECT CABLE
The connection between indoor and outdoor units, must
be carried out using a shielded cable of 3 x 0.5 mm
2
.
COMPRESSORS
All the models incorporate a Inverter compressor type
Scroll with “brushless” motor (BLDC), which by means of
an electronic system regulates the engine revolutions and
through the frequency variation adapts to the needs of the
installation and modulates the gasow of the refrigerant in
all moment.
The compressor is mounted on silentblocks.
AIR FILTER
Washable air lter, self-extinguishing material in case of
re with M1 classication, high ltering eciency, with G2
classication. With the possibility of extracting it from the
bottom and lateral side.
Optional: High Eciency Filter M5+F7.
