1. INTRODUCTION
1.1 General
The new DLS DC INVERTER split unit range comprises the following RC (heat pump)
models:
• DLS 18
• DLS 24
• DLS 30
• DLS 36
• DLS 43
Remote control compatibility
The units are compatible with remote controls RC3, RC4, RC7, RC8
Inverter description
Unlike standard units (x 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.
