2.4 Functional principle of the F800

The figure shows the refrigeration circuit with pool water condenser essentially consist-

ing of: scroll compressor (1), air-cooled condenser (4) and pool water condenser

(Option)(3), expansion valve (8) and evaporator or air- cooler (9). Refrigeration circuit

filled with refrigerant.

connection R 1/2"

Fig. 2-2: Refrigeration circuit

The hall air is evacuated by the centrifugal fan and cooled over the air cooler.

Depending on the humidity, the temperature can drop below the dew point; the water

steam in the hall air condenses on the fins of the air cooler and collects in the conden-

sate tray. The water condensate drained off through a pipe.

The dehumidified and cooled air is then re-warmed and supplied to the indoor swim-

ming pool hall.

If connected to the pool water condenser, about 65% of the thermal output is returned

to the pool water and about 35% to the hall air.

F800 Technical Description

FläktGroup DC-2013-0105-DE 2018-05/R5 • Subject to modifications11

2.5 Air ventilation operation, no dehumidification requirement

As long as no dehumidification requirement is needed with the humidity switch in the

remote control, the F800 operates at low fan speed in ventilating/air circulation mode

in order to largely avoid wet corners and clouding of the windows.

2.6 Dehumidification operation

The dehumidification is switched on with the humidity switch in the remote control

whenever the inside air humidity rises above the preset setpoint. The high fan speed

and the compressor are then automatically taken into operation.

After the inside air humidity drops by about 5% rel. hum. below the preset setpoint, the

compressor is switched off (observe minimum standing and running period) and the

fan switched back to the low fan speed.

4.1 Positioning the unit

The F800 can be installed to dehumidify indoor swimming pools or other damp areas,

directly in the swimming pool hall or damp room or in ancillary rooms (rear-wall instal-

lation).

When setting up the unit, the good air circulation should provide

a homogenous temperature and humidity profile.

Fig. 4-1: Setting up in swimming pool/damp rooms

For installation with pool wa-

ter pump: – Only set up the pool water pump in dry and frost-proof surroundings.

– Ensure sufficient fresh-air supply to avoid inadmissible warming of the drive motor.

– The pump can only be installed horizontally.

– Improper installation or opening the pump will result in loss of warranty service.

To install the unit, proceed as follows:

•If necessary, remove outer packaging.

•Grip into the air intake grille, shove it upwards, tip down and remove.

Fig. 4-2

•Unscrew both plastic screws at the lower sheet.

4.1.2 Two units in one plant

Should two F800 be required for reaching the required dehumidification efficiency,

these could be controlled and monitored in parallel by a common remote control. The

additional switch box type F8ZRK should be installed outside of the protected zone 1

and 2 (3.50 m from the pool edge), preferably outside of the swimming pool.

Fig. 4-13: F8ZRK

Electrical connection, see "Electrical installation" on page 27

4.1.3 Mixed-air operation

An improvement of the room climatic conditions can be achieved by the connection of

an outside-air connector.

NOTICE!

Units with an outside air connection must be installed at the outside wall, since addi-

tional ducts could reduce the outside air volume flow.

Minimum distances between unit and pool edge according to VDE must be observed

without fail.

Furthermore, these units must be equipped with a PWW reheater coil (accessory)

and an outgoing-air fan (see Fig. 4-21: Outgoing-air fan on page 22) must be pro-

vided (accessory).

NOTE

– In this case, a PWW additional heating register (accessory) is required, to ensure

that the supply-air temperature is not less than the hall-air temperature (avoid-

ance of air draughts).

– An air filter and equipment for the air flow rate setting must be provided building-

side and be mounted in the outside air connection! Otherwise the unit can

become soiled and the performance impaired.

4.1.4 Set up in ancillary rooms (rear wall assembly)

Units to be installed in ancillary are delivered without casing.

The ambient temperature must be at least 20° C to avoid temperature shortfalls in the

unit and air ducts.

Rear-wall units must be set up in such a way, that the unit can be connected with short

duct pieces. The maximum total static pressure is 20 Pa. The pre-assembled flexible

connection for the supply air connection can be delivered as an accessory (see

“Adapter for extract-air connection for setting up in ancillary rooms” on page 21).

The unit is equipped with an adapter for connection to on-site exhaust air lines (e.g.

flexible air hoses). This is mounted before the air intake at the lower part of the unit

(see “Adapter for extract-air connection for setting up in ancillary rooms” on page 21).

Connectors with a diameter of 180 mm are provided for the connection of the hoses.
