1.- GENERAL CHARACTERISTICS

CASING.

Galvanized and painted sheetmetal casing. The units in­corporate metal supports attached to the base, for its cor­recthoisting. These supports allow to install the unit on the
fl oor, 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 protec­tion with M1 and F1 classifi cation is used, certifying that
this material is self-extinguishing in case of fi re, avoiding
the formation of fumes that could enter the premises to be
conditioned. In the outdoor units, insulation with M1 clas­sifi cation is used.

Manufactured with copper tubes and corrugated or lour­vered aluminum fi 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.

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 gasfl ow 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 low­pressure transducers. It incorporates dehydrator fi 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
cycle and unidirectional valves. The split units also include
an oil separator.

COOLING CIRCUIT.

Washable air fi lter, self-extinguishing material in case of
fi re with M1 classifi cation, high fi ltering effi ciency, with G4

classifi cation. With the possibility of extracting it from the
lateral side.
Option: High Effi ciency Filter M5+F7.

AIR FILTER.

Designed according to standard EN-60204-1. With ther­mal 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 3x0.5mm

.

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.

Free-cooling

1.- OPERATION.
The control compares the values of temperature between outside air and room air by means of the probes; if there
is a negative difference and the safety elements allow (discharge temperature probes) then the control acts on the
servomotor, which opens the outside damper and closes the return damper, allowing cool outside air to enter the
room.
The damper is proportionally regulated. If there is not a great demand for air indoors, it may be enough just to have
free cooling to condition the room. If there is a greater demand for air, the free cooling and the unit may need to be
working in different cooling mode stages.

2.- SUPPLY AND INSTALLATION.
The free cooling option will be supplied loose.
The return probe must be installed in the return air intake duct.

2.7.- REFRIGERANT CONNECTIONS

Split units are supplied with gas and liquid lines sealed with copper covers, and located 60mm from casing.

Split units are supplied with nitrogen gas, which must be removed before carrying other operation and then
proceed as follow.

Cupper cover

Brazing

Gas

Liquid

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 2.6.1.
(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/cm

2

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 fi nal 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 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 fi t 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.

Legislation does not allow refrigerant gas emissions to the atmosphere, so the refrigerants have to be
recycled to avoid being released to the atmosphere. Those recycled refrigerants shall be processed afte­rwards by an authorized waste manager.
Those components derived from the recycling of the unit have to be managed by authorized waste mana­ger or be left in local waste facilities according the local normative in each country.

unit, follow the instructions given in the User Manual for the control supplied with the unit
(requiring operation in any of the modes, cooling, heating, or automatic).
After a time delay, the unit will start.
With the unit operating, check that the fans are turning freely and in the correct direction.

CHECK THAT THE COMPRESSOR IS ROTATING IN THE CORRECT DIRECTION:

- If you have the option phase rotation indicator, use it to check the correct rotation.

- If you do not have three phase return lock, check the correct direction of rotation. The suction pressure decreases and the discharge

pressure increases when the compressor is started.

- If the connection is incorrect, rotation will be reversed, causing a high noise level and a reduction in the amount of current consumed.

If this occurs, the compressor’s internal protection system will operate to shut down the unit. The solution is to disconnect, reverse
two of the phases and connect again.

ASTP Protection is included with the fi x speed compressors . See "Fault diagnosis" for more information.

WITH OPERATING UNIT, CHECK:

- Low pressure and high pressure.

- Use the evaporating and liquid temperature to calculate superheat and subcooling.

- Adjust the refrigerant charge and/or expansion valve according to the preceding values.

power off (see below) by employees having valid electri­cal qualifi cation and authorisation.
Electrical connections can become loose during transport.
Please check them before starting-up the unit Compres­sors with specifi c rotation direction. Check the correct
rotation direction of the fan before closing the compressor
circuit breakers. If the direction is incorrect, the phases
must be reversed at the head of the main switch.

Refrigerating circuit(s):

After more than 12 hours of power cut, the cranckcase
heater (compressor) should be powered for 5 hours be­fore any return to service. Non-compliance with this ins­truction can cause deterioration of the compressors.
Monitoring of the pressures, draining and fi lling of the sys-
tem under pressure shall be carried out using connections
provided for this purpose and suitable equipment. To pre­vent the risk of explosion due to spraying of coolant and
oil, the relevant circuit shall be drained and at zero pres­sure before any disassem bly or unbrazing of the refrige­rating parts takes place.

To evoid the risks of explosion, cooling gases elements
and oil, shall check, before carrying out any dismant-

ling or dissamble any cooling elements, that the circuit
that cause the explosion and its pressure is zero.

There is a residual risk of pressure build-up by degas­sing the oil or by heating the exchangers after the circuit

has been drained. Zero pressure shall be maintained

by venting the drain connection to the atmosphere on
the low pressure side.
The brazing shall be carried out by a qualifi ed brazier
and shall comply according to code ASME section IX
following the procedures specifi cation.

Before the start up:

- Raise the system to the test maximum pressure (see
fi rmplate).

- Check the correct behaviour of the high pressure de­vice.

- Check the components general condition and circuit
piping.

4.- MAINTENANCE

4.3.- CORRECTIVE MAINTENANCE.

IMPORT ANT:

MAKE SURE THA T THE UNIT IS FULLY DISCONNECTED FROM THE POWER SUPPLY WHEN

CARRYING OUT ANY TYPE OF WORK ON THE MACHINE.

If any component in the cooling circuit is to be replaced, follow these recommendations:

- Always use original replacement parts.

- If the component can be isolated, it is not necessary to remove the entire refrigerant charge, if the component cannot be isolating and the refrigerant
charge is removed, it should be removed through the Schrader valves located in the outdoor section. Create a slight vacuum as a safety measure.

- Regulation imposes the recovery of refrigerant fl uids and prohibits the release of refrigerant into the atmosphere.

- If cuts must be made in the pipe work, use pipe cutters. Do not use saws or any other tools that produce fi lings.

- All brazing must be carried out in a nitrogen atmosphere to prevent corrosion forming.

- Use silver alloy brazing rod.

- T ake special care that the fl ame from the torch is directed away from the component to be welded and cover with a wet rag to prevent overheating.

PRECAUTIONS TO BE T AKEN WHEN USING OF R-410A REFRIGERANT:

R-410A refrigerant is used in the unit, the following standard precautions for this gas should therefore be taken:

- The Vacuum Pump must have a Check Valve or Solenoid Valve fi tted.

- Pressure Gauges and Hoses for exclusive use with R-410A Refrigerant should be used.

- Charging should be carried out in the Liquid Phase.

- Always use scales to weigh-in charge

- Use the Leak Detector exclusive for R-410A Refrigerant.

- Do not use mineral oil, only synthetic oil to ream, expand or make connections.

- Keep pipes wrapped before using them and be very thorough about any possible dirt (dust, fi lings, burrs, etc.).

- When there is a leak, collect what remains of the charge, create a vacuum in the unit and completely recharge with new R-410A Refrigerant.

- Brazing should always be carried out in a nitrogen atmosphere.

- Reamers should always be well sharpened.

- Take very special care if 4-way or check valves are to be replaced since these have internal components that are very heat-sensitive such as
plastic, tefl on, etc.

- If a compressor is to be replaced, disconnect it electrically and un-braze the suction and discharge lines. Remove the securing screws and
replace the old compressor with the new one. Check that the new compressor has the correct oil charge, screw it to the base and connect the lines
and electrical connections.

- Evacuate above and below through the Schrader valves of the outdoor unit until -750 mm Hg is reached. Once this level of vacuum has been
reached, keep the pump running for at least one hour. DO NOT USE THE COMPRESSOR AS A VACUUM PUMP .

- Charge the unit with refrigerant according to the data on the Rating Plate for the unit and check that there are no leaks.
