1.- DEFINITIONFREE-COOLING is a saving system in the Cold cycle, this makes the unit take air from the outside to take advantageof its energy, this system acting as a first cold stage.It is a saving energy system that's why many countries regulations recommended and others put under an obligationto install a freecooling system with the unit.

2.- TYPES OF FREECOOLING.In order to outside air parameters which has to be measured, the types are:- Thermostatic freecooling :Measures and comparing the outside air temperature, with the temperature of the room that has to be aconditioned.- Enthalpic freecooling :Measures and comparing the outside air enthalpy, with the return air enthalpy from the room that has to beaconditioned.The enthalpy measures temperature and humidity of air.

3.- COMPONENTS OF FREECOOLING.The main components are:

-Electronic control and accessories: Their function is to detect the outside and indoor air conditions though theprobes, to solve when freecooling should operate-The servomotor and system transmission: They manage open and close the dampers- Adjustable dampers-Mixing section: Where outside and return air are mixed.Also an extra fan is available, which applied an additional static pressure on the suction and return air duct.

For more details about components and drawings see pages 19,20,21,22.

4.- OPERATIONThe control compares the values of temperature/enthalpy between outside air and room air through the probes,if it is a negative difference and the security elements allows (discharge temperature probes) then the control actsover the servomotor, which produces the opening of the outside damper and close the return one, entering cooloutside air to the room.

The damper regulation is proportional.If indoor air demand is not great, could be enough only the freecooling to aconditioned the room, if the air demandis greater it is possible need the freecooling working and the unit working on different cooling mode stages.

5.- THERMOSTAT TERMINAL .Depends on the type of freecooling selected, the thermostat and the electrical box supplied with the unit

will be different.

With thermostatic freecooling the thermostat supplied has the same characteristics than the one suppliedwith the standard unit, except because the one for the freecooling is a programmable one.

With enthalpic freecooling the terminal is different than the one supplied with the unit VFC version, itsprincipal characteristics are: OFF, COOL, HEAT, AUTOMATIC.

6.- SUPPLIED AND INSTALLATIONThe freecooling system could be supplied mounted or loose, depends on the unit required.

Configuration of freecooling supply :

- Split units:

7.- FREECOOLING WITH EXTRA FANIf an extra static pressure is required on the return air duct, the freecooling should add an extra fan section.This extra fan section, include a discharge damper.The operation dampers for this freecooling with extra fan is as follow:As much as the air intake damper opens, that much the by-pass damper closes and the discharge air damperopens, for the air return suction (see drawing)

This means that at the same time reach a free cooled of the room, the discharge or return air and the air of theroom gets removable.

TENSION OF BELTS

The belts can be easily tensioned through the tensingscrew incorporated into the bases of the motor of thetransmitting units which also enables a good servicing tobe carried out.

When the tensing screw is moved, the motor fan is movedto the sides in order to tension the pulley.

FLOW REGULATION IN THE FANS

The fan in the units have a variable pully incorporated into the activating motor, by which it is possible to vary,when the fan is off its diameter to modify the air flow of the unit, as required.

Always to be done through a common duct or plenum

LOCATIONThe unit can be installed outside. If it is installed, air entry and exit ducts should be fitted. The indoor unit shouldbe assembled on bases previously made and stood on absorbent and antivibrating material to avoid the vibrationsbeing transmitted to the structure of the building.

TRAPDRAIN PIPE

3.1.- PRELIMINARY CHECKS

Check that drain pipe connections and their fixtures are secure and that the level of the unit is tipped towardthe drain.Inspect the state of the ducts and grilles (clean and open grilles, no breaks in the duct, etc.).Check that the power supply is the same as stated on the Rating Plate which is in agreement with the electricaldiagram for the unit and that cable sizes are correct.Check that tightness of the electrical connections to their terminals and to ground.Inspect the Air Filter, which should be in its housing and correctly positioned(the metal grille should be toward the inside).Check with your hand that the fan turns freely.

3.- COMMISSIONING AND OPERATION

34

Remember that the Control Panel may program a notification parameter, for cleaning orreplacement of air filters depending on the number of hours of fan operation in the indoor section.

4.- MAINTENANCE

4.1.- PREVENTIVE MAINTENANCE

SIDEREMOVAL

PREVENTIVE MAINTENANCE PREVENTS COSTLY REPAIRS.

BECAUSE OF THIS PERIODIC INSPECTIONS ARE REQUIRED.

-GENERAL STATE OF THE CASING : Furniture, paint, deterioration due to bumps, rust spots, leveling and supporting, state of the shock absorbers, if installed, screwed panels, etc.- ELECTRICAL CONNECTIONS : State of hoses, tightness of screws, grounding, current draw of the compressor and fans and checking that the unit is receiving the correct voltage.- COOLING CIRCUIT : Check that pressure values are correct and that there are no leaks. Check that there is no damage to the pipe insulation, that the state of the batteries is correct and that there are no chips or clogs retained by the air flow, etc.- DRAINS : Check that water drains correctly and that the drain trays are clean.- FAN : Check that fans turn freely and in the correct direction without excessive noises.- AIR FILTER : The air filter can be removed through the side by sliding it over the rail or down. (See figure). For down removal, remove the two profiles supporting it (depending on the model) which are under the filter guide rail and screwed into the unit.

The filter should be cleaned with a vacuum cleaner or washed in soapy water.The frequency for cleaning or changing the air filters will depend on the quality air in the area (fumes, vapors,suspended dust particles, etc.).Remember that the metal grille should always be toward the inside of the unit.
