CHILLED WATER CASSETTES

INTRODUCTION

Chilled Water units of the "Cassette" type offercomfortable air conditioning at a low cost of installa-tion. They fit harmoniously into standard modules ofa false ceiling thanks to their design and small spacerequirements.

This new series is designed for easy connection andwith all connections: hydraulic, electric and junctionbox 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 electricheating modes is PROHIBITED.

1- Cassette air treatment unit

It combines excellent technical qualities, reliability andeasiness of installation.It includes :• A flat (287 mm thick), insulated unit, flash mounted

to be fitted into the false-ceiling, of a size compati-ble with standard modules of a false-ceiling (600 x600 mm).

• Three ventilation fan speeds as standard, with thepossibility of modifying the speeds on site (ifrequired), to suit the user.

• Incorporated electric heating to be connected onsite.

• Factory fitted 3 way regulation valve (option) forthe 2 and 4 tubes models. Total accessibility viathe fascia grille. Connecting hose on water side.

• Lift pump with 3 level condensate detection(Operation - Stop - Alarm) float to be installed onthe upper part of the cassette. Condensateevacuation is to be routed away from the unit bygravity (lift height up to 600 mm).

• Sliding electrical control and protection junctionbox fitted inside the unit with terminal block withscrewless terminals and multiple output auto-trans-former for possible ventilation fan speed changes(on site).

• Combined air intake and distribution grille with airfilter, manually adjustable on 4 sides, with centralair intake.

1.1. Casing• Panels and insulated sheet métal.• Combined discharge/air return grille supplied

separately for the Cassette.• Possible hand operated adjustment of air distribu-

tion on all four sides. Possibility to close one ortwo faces of discharge.

• Air return at center with filter.

• Prepunched holes for connection with fresh air intakeand connection with a stub duct to treat an adja-cent room. In that case it becomes necessary toprovide a decompression in the adjacent room(grille ...) to allow air return on the Cassette.

1.2 Insulation• Heat and sound insulation throughout the indoor

air treatment unit.

1.3 Ventilation• Centrifugal turbine with direct drive.• Motors mounted on rubbers and equipped with

internal thermal safety devices.

1.4 FiltrationCleanable air filter accessible after opening thedischarge/intake combined grille.

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 abnormalraise of temperature by two thermostats :

- a thermostat with automatic reset,- a thermostat with manual reset.

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 electricaldiagram of connection, specific instructions of instal-lation and use.

Every accessory (or kit) is delivered with technicalspecifications of assembly and adjustment if need be.The codified nomenclature of spare parts, explodedviews, technical data and recommendations foroperation and maintenance are available uponrequest.

INSTALLATION

Eau glacée TH 3421

See specifications of assembly in the installation instructions supplied with the appliance.

Indoor unitThe 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 airPlace the Air Treatment Unit in the center of the room to allow air to be distributed on all four faces of theappliance.it is possible to close the discharge on 1 or 2 faces in order to adapt the air distribution to the constraints of theroom to be treated.

Air distribution at dischargeThe 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 roomPrepunched openings at the side allow to install ducts to intake fresh air from the outside or to dischargetowards an adjacent room.

FRESH AIR INTAKEFresh 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.

Fresh air intake (Ø 100)

Air discharge in adjacent room (Ø 200)

CONDENSATE PUMP

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

Provisions should be made according to the rule book, to drain by gravity with slope and odor trap outside ofthe appliance.

ELECTRIC HEATING


��,��,��-��

�� 1 500 W

�� 2250 W

�� 2600 W

The electric heating of the cassettes is composed of heating resistances placed inside the pipes of theevaporator. These resistances are heat protected against any abnormal temperature rise by two thermostatsequipped with a "positive safety" device (mechanical or thermic destruction of the capillary switches off theheating permanently) :

• a thermostat with automatic reset,• a thermostat with manual reset.
