1. INTRODUCTION
1.1 General
The new DLS ducted split unit range comprises the ST (cooling only) as well as RC (heat
pump) models, it is available at 1PH, 3PH as follow:
•1PH => DLS 18, 24, 30, 37, 44
•3PH => DLS 18, 24, 30, 37, 44
Remote control compatibility
•The DLS unit is compatible with remote controls RC3, RC4, RCW1, RCW2
1.2 Main Features
The DLS series benefits from the most advanced technological innovations, namely:
•R410A refrigerant for all the range.
•The only Single Fan, medium capacity, low silhouette ducted unit
•High Static Pressure in the low silhouette category.
•Low indoor and outdoor sound level
•Low Silhouette 260-300 mm height that simplify the false ceiling construction.
•Small volume, easy for installation (require small space for installation)
•Water drainage capability without siphon near the unit.
•Built in over-flow protection against condensate water
•50 meters pipes installation in charge-less system
•High COP by switching to R 410Aand enlarging indoor coil sizes
•Complies with M1 regulations
•Compatible with an “all season kit” that permits operation in cooling mode up to -10ºC
outdoor temperature.
•Easy service access by removing the drain pan.
•Microprocessor control.
•Infrared remote control with liquid crystal display.

1.3 Indoor Unit
The indoor unit can fit easily to many types of residential and commercials applications.
It includes:
•High technology plastic fan and fan housing.
•A drain pool that is under the entire unit with internal downward slope.
•An over-flow switch that stops compressor operation in case drainage tube is
blocked.
•A bended coil with treated aluminium fins.
•3-speed fan motor with internal protection with extra speed for higher external
static pressure.
•Advanced electronic control box assembly with 1.8 meter cable to allow easy
installation .
•All the tubing connections are in the back of the unit to allow easy outlet to left or right
side of the unit.
•Field options:
(1) Electrical Heaters for 2005
(2) External water pump
(3) Airconet connection
(4) Plenum kit for connection of flexible hoses at air outlet.
1.4 Filtration
•The unit is equipped with pre filters.
•Easy and versatile access, rear or bottom, can be easily adjusted by the installer.
1.5 Ionizer (Optional)
A special design Ioniser protected by unique patents integrated into the indoor unit,
generating negative ions to the room providing comfort and upgraded indoor air quality.
1.6 Control
The microprocessor indoor controller, and an infrared remote control, supplied as
standard, provides complete operating function and programming. For further details,
please refer to the Operation Manual,

1.7 Outdoor Unit
The DLS outdoor units can be installed as floor or wall mounted units by using a wall-
supporting bracket. The metal sheets are protected by anti- corrosion paint work allowing
long life resistance. All outdoor units are pre-charged. For further information, please
refer to the Product Data Sheet, Chapter 2.
It includes:
•Compressor mounted in a soundproofed compartment :
Rotary – for DLS 18, 24, 30, 37
Scroll – for DLS 42, 44
•Improved 3 - blades axial fans for noise reduction.
•Outdoor coil with hydrophilic fins for RC units.
•Fan grill air outlet.
•Service valves” flare” type connection.
•Service ports for high/ low pressure measurement.
•Interconnecting wiring terminal block.
1.8 Tubing Connections
Flare type-interconnecting tubing to be produced on site.
All the units from 7KW and up can be installed with 50 m tubing length and 25 m height
difference without oil traps.
For further details, please refer to the Installation Manual.
1.9 Accessories
ASK (All Season Kit):
For low ambient working conditions in cooling, anASK can be installed inside the outdoor
unit. This kit allows cooling operation down to outdoor temperature of -10 ºC by gradually
controlling the outdoor fan speed motor.
RCW Wall Mounted Remote Control
The RCW remote control is mounted on the wall, and controls the unit either as an
infrared remote control or as a wired controller. The wired controller can control up to 10
Indoor units with the same program settings and adjustments.
For further details, please refer to the Technical Service Manual.
1.10 Inbox Documentation
Each unit includes its own installation and operation manuals.
