GENERAL INFORMATION

The air conditioner, horizontal compact, water condensed type FLW, are specially design for small and average installation, office, house etc..

On standard version you are able to incorporate electrical heater, hot water coil for use in heat.

CABINET

The cabinet is made of electrozinced steel with epoxy painted finish and finished on polyester powder. Its compact dimensions and features allow the unit to be positioned in almost any location.

Internally the unit incorporate thermal acoustic insulation to reduce sound level.

EXCHANGER

Made of copper tubing with aluminium swirl fins, they are designed and specially dimensioned to obtain the maximum output

COMPRESSOR

One compressor of the hermetically sealed type cooled with internal thermal insulation. It is mounted on vibration-absorbent blocks both on the inside and outside, statically and dynamically balanced. In all cases the compressors are acoustically isolated, resulting in silent operation.

FAN

The units include a centrifugal three speed motor fan, with a motor directly fitted (except FLW 7K with beltspully), with high performance on air flow.

CONDENSER

The unit includes condenser plate, compact and resistant made on inoxidable steel, specially selected for this type of unit.

AIR FILTER

A polypropylene washable air filter is incorporated in the unit it is accessible for maintenance

COOLING CIRCUIT

Made of welded dehumidifying copper tube with access connections. Includes dehydrator filter, liquid recipient expansion system and H.P on all models and L.P on models 3,4,5 and 7.

ELECTRIC CIRCUIT

The electrical panel includes a printed board, necessary for installation, main switch in all models, and plate circuit board ready to control the unit, and incorporate defrosting timer thermostat. the function of the unit is controlled by cable thermostat.

REMOTE CONTROL

Digital remote controller by cable at 24V, digital selector temperature which permit to choose the following function:

• Selection ON/OFF

• Three functions mode: cool, heat and fan operating.

• Two options fan operating: AUTO (automatic) which

Select turn on and stop automatically fan mode

temperature. On mode ON the fan doesn´t stop

even when temperature is selected.

• Selector three steps fan, except for model

FLW 7K, only one step.

OPTIONS

• Electrical heater mounted on fan discharge.

• Hot water coil.

• Presostatic valves regulating water flow

• Digital thermostat programmable.

WATER CONDENSER CONSUMPTION AND PRESSURE DROP

Normally, the water condense is used across a cooling tower with water temperature around 30ºC, and water flow available to work the unit with condensation temperature between 40 and 45ºC.

You are able not to use a cooling tower when the unit is near a river etc.. with enough flow and enough quality of the water. The use of the water must be used always across a previous Analysis of water.

If the water inlet temperature is below 20ºC, It is then necessary to use a regulation valve (Option) to maintain condensing temperature value between 40 and 45 ºC.

Depending inlet water temperature and condensation temperature needed you will be able to calculate water consumption following the table below.

INSTALLATION

PRE-INSTALLATION

Prior to install the equipment make sure of the following points:

• Leave enough space for access to air supply, water section, power supply and outlet condense.

• The water section must have the correspondent valves.

• Easy extraction of the air filter.

• Easy access to lateral panel for easy accessibility to all services of the unit.

• Unit must be mounted with springs.

• The electrical section must be done following legal normative

• Check that the tension is the same as installation place.

• Check the water condense quality, across analysis.

• Keep in mind water inlet temperature of the unit. Temperature below 20ºC you will need a water regulation pressostatic valve ( element as option) to maintain condensation temperature value between 40 and 45ºC.

• Depending on water entry temperature, you have to calculate the water flow following the consumption table.

• Check that air flow needed correspond for duct installation.

• Keep in mind power supply for maximum consumption for each unit.

INSTALLATION

• All installation must be carried out by qualified personnel

• Make sure that the unit is completely disconnected from the power supply before carrying out any type of work on the unit.

Hydraulic circuit:

• Make sure that the water connections are correct, inlet water (down side), outlet water (upper side)

• Fit a water filter in the outlet water connection, the step of the mesh should not be less than 0.5mm, which avoid welded and dirty get to the unit.

• If quality of water is not good, may be necessary to install a decalcified

• Install cut off valves at inlet and outlet water connections, because of in case of repairs, the hydraulic circuit can be independent.

• Install an adequate water pump, and all the elements necessaries for the installation.

• Air flow:

• All models include three fan speed motor fan.

• Make the motor fan connections for the fan speed required to adequate the air flow needed for the installation

• Drainage tube:

• Use the flexible tube connected to the tray as a drainage tube.

Cause a siphon with this tube in order to avoid the inlet of scents from the installation to the unit.

• Install a siphon from the drainage tube of tray with a difference in height of 80 mm to prevent these from not evacuating due to the negative pressure created by the fans. The pipe will have a 2% slope to make it easier for the condensates to drain off.

SERVICE AND MAINTENANCE

• The unit under supply, have rotating objects and high temperature into the pipe. Make sure to turn off electrically the unit before to access for maintenance or revision.

• Air filter: Clean the filter (maximum each 6 months), but the clean of the filter depend on the ambient where the units is working.

• Water filter: Realise a clean of the filter.

• Security elements: The unit include electrical elements of security( Internal thermal protection on the compressor and motor fan, external thermal protection on the compressor and motor three phase) and cooling elements of security like high and low pressostat pressure with electrical rearm. If limits of function of the unit is out of conditions of work, some protections will be display.

LOCALISATION OF PROBLEMS

PROBLEMS

• Cut low pressure (Electrical rearm) (*)

• Cooling capacity low.

• Freeze on coil

CAUSES

• Air in temperature very low

• Defect on refrigerant charge.

Test that the refrigerant is correct.

• Air filter dirty

• low air flow.

• Water temperature is too low

• Cut high pressure (Electrical ream) (*)

• High consumption

• Thermal compressor protection cut

• High water temperature

• Low air flow

(*) Rearm electrically the unit turning off/on, after repair the cause which produce a cut on high and low pressure.

PRESOSTATIC VALVES

If water inlet temperature is below 20ºC we recommend to maintain level condensation temperature in (40 a

45ºC)

FUNCTION

The presostatic valve maintain some values of the condensation pressure regulating the water flow which enter into the condenser.

When the condensation pressure is up, the valve open and water enter. and when pressure is low the valve close.

INSTALLATION

• Substitute the out pipe of the exchanger plate into the

unit for a presostatic valve.

• Keep in mind the row indicated in the valve.

• El vastage regulation must be above for easy access to the regulation.

• Connect the capillary tube of the valve to the plug of high pressure in the pipe of the unit.

REGULATION PRESOSTATIC VALVES

• Connect a manometer of high pressure (30 bar) near the refrigerating circuit of the unit.

• Turn over the vastage in the head of the valve( right the valve open, left the valve close) regulating the water flow which enter into the unit.

• You must leave the unit working during 10 minutes and see the indication of the manometer. If the condensation pressure temperature is approximately 45ºC the valve is correctly regulated. If not restart the regulation described before.
