Description

Fläkt Woods 9324 GB 2014.04 2 Specifications are subject of alteration without further notice.

 

 

Casing

It is made from galvanized steel insulated with polyolefin(PO) foam (class M1).

Fan assembly

Consists of quiet centrifugal fans in galvanized steel withtwo impellers and a directly-driven, single-phase fourspeed motor, 230V 50Hz, with capacitor, insulation classB.

Coil

It is manufactured from drawn copper tube and thealuminium fins are mechanically bonded onto the tube byan expansion process.The connections are on the left hand side looking from theair inlet of the unit (see dimensions pages).On request or on site the connections can be moved to theother side.The coil is not suitable for use in corrosive atmosphereor in environments where aluminium may be subject tocorrosion.

Filter

The filter is made of polypropylene cellular fabricregenerating filter. The filter frame of galvanized steel isinserted into special PVC sliding guides fastened to theinternal structure for easy insertion and removal of thefilter.Easy access to the filter for cleaning operation.On request is available a 48 mm synthetic filter, G3,efficiency of 84% Eurovent EU3 or F6 (only size 6 and 7)according to EN779.

Acoustic Data

Fläkt Woods 9324 GB 2014.04 8 Specifications are subject of alteration without further notice.

Often sound levels are the key influencing factor in the selection of equipment. The notion sound power is oftenconfused with the notion sound pressure. The two notions can be defined as follows :

Sound power (Lw) Sound pressure (Lp)

Sound power is the output required producingsound pressure waves. It is not, as such, directlymeasurable.Sound power is established by measuring thesound pressure on the inner surface of a sphereplaced around the source. It is measured andstated in Watts.Sound power is therefore a measurement, whichis not dependent on area or distance, and it isused as a basis for all acoustic data.

This is the alternating pressure produced bywaves from a sound source. It is a measure of thenoise level or noise intensity.Sound pressure is dependent on the averageabsorption factor of the room, distance fromthe sound source, the position of the unit in theroom, the occupation and is therefore not suitablefor calculations of sound propagation or spread.

 

An explanatory example:

The sound power level can be compared with the heating capacity of a boiler. This capacity will remain the sameregardless of the thermal characteristics of the installation.The sound pressure level can be compared with the temperature obtained in a room supplied from the boiler. Obviously,the temperature will vary depending upon the room characteristics and so it is with sound pressure.Therefore, accurate comparisons between competing equipment should always be made, in the case of the boiler, bycomparing boiler capacity and in case of fan coil units by comparing the sound power levels.

Conversion: Sound power level dB(A) => Sound pressure level dB(A)

Practical guidelines

Fläkt Woods 9324 GB 2014.04 9 Specifications are subject of alteration without further notice.

Precautions to be taken before and duringinstallation

• Units are carefully inspected and tested prior todelivery.

• The water system must be carefully designedand balanced if the fan coil system is to performcorrectly.

• The units should be installed in such a wayto allow easy access for maintenance andadjustments.

• It is important that the unit is placed level orslopes slightly towards the condensate drain side.

• Sufficient slope of the drain system shall beassured for a quick condensate removal = 2 %(min. 2 cm/m).

• The inlet water connections for cooling andheating are always the lower of the coilconnection.

• Although units equipped with water controlvalves have been carefully checked at the factory,it is advisable to check the tightness of all pipeconnections on site using a spanner.

• Make sure that the condensate will drain offfreely.

• Do not connect the drain system directly tothe drainpipe of the main drip tray but usethe drainpipe of the auxiliary drip tray for theevacuation of the condensate.

• It is recommended to seal the joint between theunit and the auxiliary drip tray with a sealer.

• The distance between the air intake side and thefloor or wall should be minimum 100 mm.

• Make sure that no shelving or furniture obstructsfree air circulation.

• Dispose of packaging material in accordancewith local requirements.

Electrical connections

• All motors are tested prior to delivery.

• The voltage of the motor is stated on theidentification label of each unit.

• The electrical wiring of the units should be doneby an authorised electrician in accordance withthe local regulations.

• The electrical heating elements must only befactory installed.

• The electrical installation should be of permanenttype and the unit protected by means of fuses inthe power supply from the mains.

• Incorrect field wiring will cause motor damage.

• Always use the same power supply circuit for thefan coil system (fan coil units, thermostats, etc. ..)

• Do not connect more than one fan coil unit to onecommon speed selector switch.

• In master/slave applications, check carefully theequipotentiality of the electrical connections.

Control system

• When the fans are not running, it is stronglyadvisable to ensure that the chilled water supplyto the coils is automatically shut off, to preventcondensation in and on the unit.

• Units equipped with electrical heating elementsmust be connected to a regulation withpermanent ventilation.

Starting-up

• Check that the coils have been cleaned after theinstallation work.

• Check the water system and open the valves forthe water supply.

• Check that the water connections do not leak.

• Open the venting screws and check that there isno air in the coils.

• Equalisation of the pressure drop across thewhole water system is recommended.

• Check that the fan impeller rotates freely and inthe correct direction.

• Run the fan at high, medium and low speed andcheck that no mechanical noise can be heard.

• Check that the unit is well secured and does notvibrate.

• Check the performance of the supervisorysystem.

Maintenance

• Before performing any service or maintenanceoperations, turn OFF the main power supply.

• Inspect the unit at regular intervals.

• The frequency of cleaning the coil and the driptray depend on local conditions.

• The coil should be cleaned on both sides. Use avacuum cleaner with a rubber nozzle.

• Work carefully to avoid damaging the coilsurfaces.

• Check that the drainpipe is clean and notclogged.

• The motor bearings are permanently lubricatedand do not require lubrication.

• The standard filters are of the washable type andshould be cleaned when clogged.

• Check min. once a month the filter – finalpressure drop is recommended up to 25 Pa.

• The frequency of filter cleaning or replacementis dependent on the dust content in the returnair. (our recommendation: Max. 1 month afterstarting-up period and further min. every 3months)

Fläkt Woods 9324 GB 2014.04 10 Specifications are subject of alteration without further notice.

WARNING!

• The cooling and heating output of the unit willbe reduced if the unit is running with cloggedfilters.

• Unit mounted electrical heating elements caninfluence the sound level of the units.

• Dirty/clogged filters will increase the sound leveland are harmful to the operation and working-expenses of the units.

• Prolonged operation with a dirty / clogged filtermay lead to deterioration of the motor.

• To avoid breaks caused by ice, please empty thewater circuit when the room temperature goesdown to 0 °C .
