FläktGroup CAIRfricostar is a unit mainly designed for private swimming pools. It can be used to dehumidify and heat air in swimming pools in a recirculating-air mode.
The unit is supplied with a standard electric controls comprising a remote control sensor in the pool area for dehumidification and reset switch. Two LED-lamps indicate operating and error messages of the unit.
For energy saving purposes, air is recirculated without being dehumidified in recirculating-air mode and only reduced air flow is heated. In the second speed the unit starts operating with normal air flow and regular dehumidification mode. At the same time the compressor is activated and humid air is dried using the evaporator. In addition air is heated using condenser oil.

1 Functional description of the unit
The CAIRfricostar CAU is mainly designed for private swimming pools and can be
delivered in 4 sizes. The unit operates to dehumidify and heat air in swimming pools in
a recirculating-air mode.
The unit is supplied with a standard electric controls comprising a remote control
sensor in the pool area for dehumidification and reset switch. Two LED-lamps indicate
operating and error messages of the unit.
For energy saving purposes, air is recirculated without being dehumidified in recircu-
lating-air mode and only reduced air flow is heated. In the second speed the unit starts
operating with normal air flow and regular dehumidification mode. At the same time the
compressor is activated and humid air is dried using the evaporator. In addition air is
heated using condenser oil. At this point install the temperature sensor in the pool
water circuit.
1.1 Operation mode with dehumidification demand
Supply air fan runs at high speed. The necessary transmission heat is supplied by the
re-heater coil. Using an optional pool water condenser a certain amount of excess
energy can be fed back into swimming pool water.
IMPORTANT
DAMAGE TO THE UNIT!
Please consider that the water flow through pool water condenser is limited
to 700 l/h. A larger water flow causes irreparable damage to the pool water
condenser.

Installation of the remote control within the swimming pool
enables to measure average air humidity.
Humidity setpoint in the swimming hall amounts to 40-60% r.h.
•Mount the remote control at a height of 1.5 to 1.8 m and a
minimum 1 m from away from doors, windows and radiator/
heating surfaces.
•Open the casing, mark the screw holes and use the appro-
priate fixing material to secure the casing on the wall.
•Avoid direct solar radiation, contact with cold walls
and components and direct air discharge caused by
FläktGroup CAIRfricostar unit.
•Protect the remote control against splash water!
3.6 Operating remote control
1 Operator switch with functions „I“ (ON) and „0“ (OFF);
