1.- GENERAL CHARACTERISTICS
CASING.
Galvanized and painted sheetmetal casing. The units in-
corporate metal supports attached to the base, for its cor-
recthoisting. These supports allow to install the unit on the
floor, providing great rigidity to the installation of the unit.
The panels are easily interchangeable allowing several
alternatives of impulsion and return air. The outdoor and
indoor sections are insulated thermally and acoustically. In
the indoor units, an insulation with aluminum mesh protec-
tion with M1 and F1 classification is used, certifying that
this material is self-extinguishing in case of fire, avoiding
the formation of fumes that could enter the premises to be
conditioned. In the outdoor units, insulation with M1 clas-
sification is used.
Manufactured with copper tubes and corrugated or lour-
vered aluminum fins, 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.
EXCHANGERS.
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 gasflow of the refrigerant in
all moment.
Two circuit units incorporate also tandem compressor,
scroll type.
The compressors are mounted on silentblocks.
COMPRESSORS.
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.
FANS.
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 filter, 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
cycle and unidirectional valves. The split units also include
an oil separator.
COOLING CIRCUIT.
Washable air filter, self-extinguishing material in case of
fire with M1 classification, high filtering efficiency, with G4
classification. With the possibility of extracting it from the
lateral side.
Option: High Efficiency Filter M5+F7.
AIR FILTER.
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.
ELECTRICAL CIRCUIT.
1.2.- GENERAL DESCRIPTION.
GENERAL SWITCH.
Located in the access panel to the electrical board and
equipped with a mechanism which only allows the opening
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 hose of 3x0.5mm2.
The vertical self-contained conditioners, Compactair Advanced range, in the heat pump version are air condensed
units that have been designed for small commercial and residential installations. The units consist of two sections,
an indoor section and an outdoor section, are units that by their design can be supplied in package and split version.
They are designed for operation coupled to a network of air distribution ducts in indoor and outdoor sections. With the
option of incorporating a wide range of accessories and options.
The manufacturing of these units is made under the strict quality requirements of the standard ISO 9001.
