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 some units. The units are available with cooling capacities from
1950 to 8450 W and heating capacities from 1400 to 10600 W.
CABINET
The unit chassis is made of galvanised steel and is fully insulated inside.
The units have been designed in order to install them in high ceilings where standard plates 600x600 mm or
600x1200 mm will be used.
DIFFUSER PANEL
Two alternatives can be chosen:
- Plastic diffuser: Made in decorative plastic, with a smooth finish. Internal insulation prevents condensation from
forming. 4 louvres for MODELS 600x600 and 6 louvres for MODELS 600x1200 ensure air distribution.
- Metallic diffuser.
HEAT EXCHANGER
Made of copper tubes and aluminium fins. Coils have been designed and manufactured to ensure maximum
efficiency.
FAN
The units are supplied with one (models 600x600) or two (models 600x1200) 3-speed centrifugal fans. The impeller
blades have been designed specifically for this type of units ensuring exceptionally low sound levels and the motor
is protected with internal thermal protection.
AIR DISTRIBUTION
The position of the louvres can be adjusted manually (only for plastic diffuser).
AIR FILTER
A polypropylene washable air filter is incorporated in the unit; it is easily accessible for maintenance.
INTERNAL COMPONENTS
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.
ELECTRIC CIRCUIT
The electrical panel is provided with a terminal block which provides connection to mains power or to a control box
(depending on model).
A fused isolator is not included and where required shall be installed by others.

WATER PRESSURE DROP WITH GLYCOL
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 following table:

• Side knockouts panel are provided. One to connect a fresh air inlet duct, and another to connect an air distribution
duct to deliver air to an adjacent room.
FRESH AIR MAKE UP (FIG. 5)
INSTALLATION
• Remove the 68 mm insulation material and cut out the prepunched side knockouts.
• Secure the duct connection flange to the unit. Conducts can be of flexible polyester type or corrugate aluminium,
externally covered with anticorrosion material.
• Install a supplementary fresh air fan for the introduction of fresh air into the unit. The fan motor must be controlled
by an ON-OFF switch.
• Fresh air flow must be less than 10% of the total air flow, to avoid operating problems. A speed controller should
be installed in the supplementary fan motor, for adjusting the air flow.
AIR SUPPLY TO AN ADJACENT ROOM (FIG. 6)
INSTALLATION
• Remove the 150 mm insulation material and cut out the prepunched side knockouts. For models 600x600, the
two prepunched side knockouts must not be used at the same time to provide conditioned air to an adjacent
room. For models 600x1200, do not use the same fan to provide air conditioned to both ducts.
• Cut away the polystyrene around the inside edge of the opened panel, remove the polystyrene.
• Use a duct connection flange and a suitable duct.
• Air supply to an adjacent room requires that outlet corresponding with the duct is closed.
• An air inlet grille must be fitted (if possible near the floor) between the air conditioned room (where the unit is
situated) and the adjacent room.
• Conducts can be of flexible polyester type or corrugate aluminium, externally covered with anticorrosion material.
The duct length can be calculated by taking into account the pressure drop through the unit, using the following
table:

AIR DISTRIBUTION
Louvres change position to distribute air according to heating or cooling
operation (only for plastic diffuser).
• 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.
