or mounted on the floor.
Panels are easily inter exchangeable, giving several air suction
and return alternatives.
An insulation with a protection of mesh is used in indoor section
with a classification of M1 and F1, certifying that the material is
auto-extinguishable and avoiding the fumes inside the room to
be aconditionned. Auto extinguishable insulation M1 is used in
outdoor units.
COMPRESSORS
All units are provided with scroll compressor, cooling by a suc-
tion gas with thermic protection inside the engine, so no other
additional protection is required.
Itis mountedonanti-vibration devicesbothexternal and internal.
All compresors are R410A
In heat pump units the compressors are provided with a crank-
case heater to heat the oil in the compressor so that a suitable
lubrication can take place.
AIR FILTER
Washable air filter; auto extinguishable material with M1 clas-
sification, high efficiency filtrate with G2 classification. It can be
removed through the upper part and from both sides.
FAN
Outdoor and indoor fans are centrifugal with an assembled
engine, statically balancing, with a low sound level.
Those fans are assembled to the inserted panel of the units and
split from upper side of the fan with insulated materials to void
vibrations.
EXCHANGER
Made-up with copper pipes and aluminium fings, designed to
get a high heat transfer.
Their dimensions and design of the refrigenrant circuit have
been specially worked to obtain the maximum performance of
the exchanger increasing the power of the unit and reducing
the consumption.
COOLING CIRCUIT
Carried out with welded deshydratable copper pipes with pres-
sureintakes withschraedervalves inthe suction andliquid lines
both indoors and outdoor units.
In unit 20-25-30 the pressure intakes in the outdoor section are
approachable from the outer part of the unit.
The unit is equipped with both high-low pressure switches with
an automatic reset. It also has a dehydrating filter, expansion
system with restrictors in units 10-12-15; expansion valves in
units20-25-30.The heat pump units are equipped aswell with a
suctionaccumulator to avoidthe liquid return to thecompressor,
4 way valve and no-return valve.
ELECTRICAL CIRCUIT
Designed according to EN 60204-1 normative hermetically
sealed to avoid condensation. With circuits breakers to protecto
the unit from overloading.
1.1- GENERAL DESCRIPTION
The horizontal air conditioning units, range Flatair, cooling only or heat pump are air condensed units designed for small shopping
center and housing. They can be supplied either compact or on split system.
Due to their small dimensions they are designed for false ceiling and can be placed in air conducts both indoor and outdoor sec-
tions.
A wide range of optionals, completed-factory assembled are also available.
Flatair units are designed for false ceiling mounting, to be installed exclusively indoor. For outdoor moun-
ting, a shelter or roof structure has to be installed, to avoid direct water entry in the sensible parts of the
unit (electrical board, joints between the indoor unit and the outdoor unit).
