1. INTRODUCTION
1.1 General
The new GC 36 / 43 / 60 DC INVERTER ducted split unit range comprises the following
RC (heat pump) models:
• DLS 36
• DLS 43
• DHC 36
• DHC 43
• CD 60
Remote control compatibility
The units are compatible with remote controls RC3, RC4, RCW1, RCW2, RC7.
Inverter description
Unlike standard units (fix RPM) that are selected according to their nominal capacity to
overcome the maximum required load, DC Inverter units can be selected to a smaller
nominal capacity range unit.
It made possible due to the ability of inverters to reach a much higher capacity level
(indicated as Maximum Capacity) which is around 115-130% of the nominal capacity.
1.2 Main Features
High Technology
•Sine wave DC Compressor drive.
•DC-BL-SL (DC Brush-Less Sensor less) Inverter Compressor.
•DC-BL Inverter Outdoor Fan.
•Fuzzy Logic Adaptive Control.
System Features
•Variable cooling and heating capacity from 30% to 115% (of rated capacity).
•High COP “A-B” class energy rating (Most units).
•Low noise levels.
•Pre-charged system up to 30m.
•Tubing up to 70m length / 30m height difference.
•Networking connectivity.
•Current limitation setting for circuit breaker size reduction (if required).
•Dry contact inputs:
♦Standby.
♦Night mode (for silent operation in cooling).
Power Shedding (to control maximum power consumption).
•Dry contact output:
♦Alarm
♦Base Heater
♦Crank Case Heater

(3) Plenum kit for connection of flexible duct 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 Control
The micro processor 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, Appendix A.
1.6 Outdoor Unit
The GC DCI 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.
•Compressor mounted in a soundproofed compartment.
•Improved 3-blades axial fans for noise reduction.
•Outdoor coil with hydrophilic fins optimized for operation with R410A refrigerant.
