GENERAL INFORMATION

The CEILING CASSETTES are designed to operate with chilled and hot water. They
provide both cooling and dehumidification in cooling mode and heating in the latter,
cleaning and filtering the air in the process. Electrical heating elements are available
as an option on all units excluding the CW050. The units are available with cooling
capacities of 2000 to 5200 W and heating capacities of 2800 W to 6000 W.

The unit chassis is made of galvanised steel and is
fully insulated both inside and out.

Made of copper tubes and aluminium fins. Coils
have been designed and manufactured to ensure
maximum efficiency.

The units are supplied with a 3 speed centrifugal
fan. The impellor blades have been designed
specifically for this type of units ensuring
exceptionally low sound levels and the motor is
protected with internal thermal protection.

The air discharge louvres change position in
automatic or manual mode, (according to versions).
In the case that this function has not been
incorporated the position of the louvres can be
adjusted manually.

The unit is designed, with serviceability in mind, and
all components are easily accessible. A drip tray
collects condensate which is removed by means of
a condensate pump.

Made in decorative plastic, with a smooth finish.
Internal insulation prevents condensation from
forming.
Four louvres ensure air distribution.

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

As the percentage of glycol increases the
standard pump flow decreases due to the
increased pressure characteristics. This
means that the cooling and heating duties
will decrease. As a result the pressure
drop must be multiplied by the coefficient
shown in the table below.

POWER SUPPLY WIRING

This equipment must be installed in accordance

with national regulations. A suitable means of

disconnecting all supply poles must be provided
in the power supply wiring. The power supply must
incorporate suitably rated fused or circuit breaker

Louvres change position to distribute air according to heating
or cooling operation.

• In cooling operation the louvres are positioned to distribute
air outwards from the discharge, which allow airflow close to
the ceiling.

• In heating mode the louvres are repositioned to blow air in a
downward direction. The air should flow towards to the floor to
prevent layers or stationary hot air forming in the upper part of
the room.

Depending on the control, the louvres may be set on intermediate
positions; as well the louvres may be set to move continuously,
sweep mode. (For more information, see the remote control
manual.)
When the Electro-mechanical thermostat is used the louvres
movement is manual, louvres should be positioned manually.
