CHILLED WATER CASSETTES
• Prepunched holes for connection with fresh air intake
and connection with a stub duct to treat an adjacent room. In that case it becomes necessary to
provide a decompression in the adjacent room
(grille ...) to allow air return on the Cassette.
INTRODUCTION
Chilled Water units of the "Cassette" type offer
comfortable air conditioning at a low cost of installation. They fit harmoniously into standard modules of
a false ceiling thanks to their design and small space
requirements.
1.2 Insulation
• Heat and sound insulation throughout the indoor
air treatment unit.
This new series is designed for easy connection and
with all connections: hydraulic, electric and junction
box accessible behind the fascia grille.
• Cooling (Chilled water) and electric heating.
• Heating (Hot water). Its design allows for an inlet
water temperature up to 80°C.
Simultaneous operation in hot water and electric
heating modes is PROHIBITED.
1.3 Ventilation
• Centrifugal turbine with direct drive.
• Motors mounted on rubbers and equipped with
internal thermal safety devices.
1.4 Filtration
Cleanable air filter accessible after opening the
discharge/intake combined grille.
1- Cassette air treatment unit
1.5 Electric heating
• The Cassettes are factory-equipped (option) with
electric heating to be connected on site.
• The electric heating equipped with heating
resistances is heat protected against any abnormal
raise of temperature by two thermostats :
- a thermostat with automatic reset,
- a thermostat with manual reset.
It combines excellent technical qualities, reliability and
easiness of installation.
It includes :
• A flat (287 mm thick), insulated unit, flash mounted
to be fitted into the false-ceiling, of a size compatible with standard modules of a false-ceiling (600 x
600 mm).
• Three ventilation fan speeds as standard, with the
possibility of modifying the speeds on site (if
required), to suit the user.
• Incorporated electric heating to be connected on
site.
• Factory fitted 3 way regulation valve (option) for
the 2 and 4 tubes models. Total accessibility via
the fascia grille. Connecting hose on water side.
• Lift pump with 3 level condensate detection
(Operation - Stop - Alarm) float to be installed on
the upper part of the cassette. Condensate
evacuation is to be routed away from the unit by
gravity (lift height up to 600 mm).
• Sliding electrical control and protection junction
box fitted inside the unit with terminal block with
screwless terminals and multiple output auto-transformer for possible ventilation fan speed changes
(on site).
• Combined air intake and distribution grille with air
filter, manually adjustable on 4 sides, with central
air intake.
2. Available kits and options
Various regulation kits are available :
• 3 way valve option, with motorised by-pass for the
2 and 4 tubes versions.
• Ventilation fan 3 speed switch.
• Thermostat and manual summer / winter mode
control.
• Thermostat and automatic summer / winter control.
• Thermostat and automatic summer / winter control
with change-over.
• Extension frame for solid ceiling.
3 - DOCUMENTATION
Every appliance is supplied with it basic electrical
diagram of connection, specific instructions of installation and use.
1.1. Casing
• Panels and insulated sheet métal.
• Combined discharge/air return grille supplied
separately for the Cassette.
• Possible hand operated adjustment of air distribution on all four sides. Possibility to close one or
two faces of discharge.
• Air return at center with filter.
Every accessory (or kit) is delivered with technical
specifications of assembly and adjustment if need be.
The codified nomenclature of spare parts, exploded
views, technical data and recommendations for
operation and maintenance are available upon
request.

INSTALLATION
See specifications of assembly in the installation instructions supplied with the appliance.
Indoor unit
The Air Treatment Units is to be flush - mounted into a false ceiling of standard 600 x 600 mm modules.
Fastening is carried out with threaded rods to be fixed on clamps which are supplied.
Distribution of treated air
Place the Air Treatment Unit in the center of the room to allow air to be distributed on all four faces of the
appliance.
it is possible to close the discharge on 1 or 2 faces in order to adapt the air distribution to the constraints of the
room to be treated.
Air distribution at discharge
The louvers of air discharge of the treatment unit can be set in three different, clearly defined positions
Fresh air intake and treated air discharge towards an adjacent room
Prepunched openings at the side allow to install ducts to intake fresh air from the outside or to discharge
towards an adjacent room.
Fresh air intake (Ø 100)
Air discharge in adjacent room (Ø 200)
FRESH AIR INTAKE
Fresh air flow should not exceed 12% of nominal air flow (See table hereunder).
An anti-fost thermostat preset at + 5°C, installed on site on fresh air intake is mandatory for winter application.
A filter, fan and insulated air duct (not supplied) are to be installed on site.

CONDENSATE PUMP
The smallzised condensate pump is built into the air treatment unit. It has been especially designed to lift and
remove condensates from the upper part to improve draining. Provide for draining by gravity with a slope and a
siphon outside of the appliance, according to the rule book.
3 levels including 1 of security on the float of control.

ELECTRIC HEATING
The electric heating of the cassettes is composed of heating resistances placed inside the pipes of the
evaporator. These resistances are heat protected against any abnormal temperature rise by two thermostats
equipped with a "positive safety" device (mechanical or thermic destruction of the capillary switches off the
heating permanently) :
• a thermostat with automatic reset,
• a thermostat with manual reset.
