1 - GENERAL DESCRIPTION
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 sections.
A wide range of optionals, completed-factory assembled are also available.
FURNITURE
EXCHANGER
Painted in galvanized metal furniture, high resistant to corrosion.
The units are provided with metal profiles, capable of withstanding
the unit and able as well of installing the unit hung from the ceiling
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.
Made-up with copper pipes and aluminium fings, designed to
get a high heat transfer.
COMPRESSORS
All units are provided with scroll compressor, cooling by a suction gas with thermic protection inside the engine, so no other
additional protection is required.
It is mounted on anti-vibration devices both external and internal.
All compresors are R410A
In heat pump units the compressors are provided with a crankcase 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 classification, high efficiency filtrate with G2 classification. It can be
removed through the upper part and from both sides.
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 pressure intakes with schraeder valves in the suction and liquid 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
units 20-25-30. The heat pump units are equipped as well with a
suction accumulator to avoid the liquid return to the compressor,
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.
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.
Flatair units are designed for false ceiling mounting, to be installed exclusively indoor. For outdoor mounting, 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).

Split units are supplied with gas and liquid lines sealed with copper covers, and located 60mm from casing.
Service ports
Gas
Cupper
cover
Brazing
Terminal
block
Liquid
Split units are supplied with nitrogen gas, this must be removed and then proceed as folow:
1. Remove the nitrogen gas through the high and low 5/16” service ports located inside and provide a low vacuum for safety.
2. Remove the caps from the connecting lines.
3. Braze the piping connection lines. Select piping diameter from table 2.7.1.
(When brazing refrigerant pipes, nitrogen gas must be supplied into the pipes through the service ports to remove the air).
4. Leak test:
Add nitrogen gas, check that a pressure of 5 kg/cm2 has been reached and that there are no leaks in the circuit or brazing
by applying soapy water to the pipes which will cause the bubbles to form where there are leaks.
To detect small leaks, proceed as follows:
Add nitrogen gas and check that a pressure of 25 kg/cm2 has been reached, there are no leaks if the pressure remains the same
for at least 24 hours and the final pressure is not less than 10% below the initial pressure.
5. Ensure that the gas line is insulated.
6. Evacuation:
Remove the nitrogen gas, connect the gauge manifold and vacuum pump to both the liquid and gas lines, fully open the gauge
manifold valve and switch on the vacuum pump. Check to make sure the gauge shows a pressure of -750mm Hg. Once a level
of -750mm Hg is reached, keep the vacuum pump running for at least one hour.
7. Refrigerant charge:
- Check TABLE 3.1. and 3.2. for the amount of refrigerant charge, depending on the length and size of the pipe connections.
- Disconnect the vacuum pump and connect to the refrigerant-charging bottle. Open the charging pump and purge the air from
the hose at the pressure gauge manifold.
- Set up the amount of additional refrigerant on the weighing scale, open the high pressure and charged in the liquid state. If the
total amount of refrigerant charge has not been reached because the pressure is balanced, turn off the high side of the gauge
manifold, turn on the unit, and add the remaining amount of the refrigerant charge required slowly through the low side of the
pressure gauge. (With R-410A refrigerant, the charging bottle must be in a vertical position and charged in the liquid state).
Close the pressure gauge, disconnect it from the from the service port of the unit and fit caps on the service ports. The unit is
then ready to operate.
During installation operations, keep gas and liquid pipes covered, in order to prevent humidity and dirt,
get into them.
Take special concern about refrigerant pipes are isolated.
Avoid collapse on line installation.
