PRESENTATION

These units are optimi-

sed for operating with

chlorine-free R-407C refrige-

rant having no harmful effects

on the ozone layer.

Refer to the correspon-

ding manuals and always

follow their recommenda-

tions when working on the

units.

The "KXL Cassettes" range of individual air conditioners with its standard

square 900 x 900 mm format and extremely silent operation is perfectly

suited to suspended ceiling mounting. This series has been designed for

easy servicing and offers quick access to all components after simple

removal of the fascia panel.

These appliances are available in the two versions :

• Cooling Only version with capacities from 7150 to 12500 W.

• Heatpump version with capacities from 7520 to 14200 W.

1. KXL air treatment cassette

This unit allies quality with reliability and ease of installation.

It comprises :

• A low height casing (KXL 24/30 : 230 mm, KXL 36/45 : 300 mm) to be

flush-fitted easily into all types of suspended ceilings.

• Three fan (ventilation) speeds.

• Treated air blowing on all 4 sides with motorised grille flaps

(AUTOSWEEP).

• Integrated condensate lift pump.

• New air intake.

• RC4 infrared remote control with display (see page 33).

• Air filter.

2. Air condenser unit

Of compact design, taking up very little floor area, this unit houses the

"Scroll" compressor, the fan-condenser assembly and the electrical con-

nections and control box.

3. Refrigeration connections

Both the indoor and outdoor units are equipped with "FLARE" connectors,

enabling the use of "FLARE" refrigeration pipes (refrigeration quality copper

pipe equipped with nuts at both ends).

4. Accessories

a) Available as an option : supply with electric heating

KXL 24 : 1800 W

KXL 30 / 36 : 4200 W

KXL 45 : 5100 W

b) Hardwired RCW-2 type wall-mounted remote control (See page 35).

5. Documentation

Each unit is supplied with general wiring and connection diagrams and

specific installation and operation instructions.

Each accessory (or kit) is accompanied by technical specifications for

fitting and adjustment as required.
