1. INTRODUCTION

1.1 General

The new DLF DC INVERTER concealed split unit range comprises the RC (heat pump)

models as follow:

● DLF 25

● DLF 35

● DLF 50

● DLF 60

● DLF 72

Remote control compatibility

The DLF unit is compatible with remote controls RC3, RC4, RCW1, RCW2, and RC7.

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 level DC inverter system combined with concealed indoor units.

The system consists of high technology DC Brushless compressor, outdoor and indoor

fan motors.

The system adopts new ODP free refrigerant R410A and other environmental regulations

such as RoHS, WEEE, etc.

We believe this is the most suitable solution for residential and light commercial air

conditioning.

The indoor with only 200 mm height and together with the integrated water pump allows

best ﬁt into very low ceiling space.

The units’ unique feature is the option of install the unit in horizontal or vertical position

without any additional work.

The unit low noise level (up to 25 DBA) ﬁts perfectly for application as hotels, bed room

and small ofﬁces.

The DLF series beneﬁts from the most advanced technological innovations, namely:

 Variable cooling and heating capacity from 30% to 115% (of rated capacity)

 High COP

 Low noise levels in both indoors and outdoors

 Extreme low silhouette, only 200mm.

 Pre-charged system up to 30m

 Tubing up to 50m length and 30m height difference

 Networking connectivity

 Dry contact output – Alarm

 Ready for base heater and crank case heater installation including software support

 HMI Display consists of 7-segments shows system diagnostics and setup (in some

models only)

 Monitoring software (PC port for high level service)

 Operating range cooling: From -10ºC to 46ºC outdoors

 Operating range heating: From -15ºC to 24ºC outdoors

1.3 Indoor Unit

The indoor unit can ﬁt easily to many types of residential and commercials applications.

It includes:

 Water-pump drainage build-in.

 Emergency Water-ﬂoat to prevent over ﬂow.

 Horizontal/ Vertical installation build in.

 2 options of return air location, on back of the unit or bellow the unit.

 DC BL motor with maximum fan speed ﬂexibility.

 High technology plastic fan and fan housing.

 Advanced electronic control box assembly with 1-meter cable to allow installation at

a more accessible area.

1.4 Filtration

The air ﬁlter can be located in the back side or in the bottom of the unit for easy ac-

cess.

1.5 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, Appendix A.

1.6 Outdoor Unit

The 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 paintwork 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 DLF 25-35

Scroll – for DLF 50-60-72

● Improved 3- blades axial fans for noise reduction.

● Outdoor coil with hydrophilic ﬁns for RC units optimised for operation with R 410A

refrigerant.

● Fan grill air outlet.

● Service valves” ﬂare” type connection.

● Interconnecting wiring terminal block.

1.7 Tubing Connections

Flare type-interconnecting tubing to be produced on site.

For further details, please refer to the Installation Manual, Chapter 9.
