SM FBFRPM 1-A.0 GB
1.5 Control
The microprocessor indoor controller, and an infrared remote control, supplied as
standard, provide complete operating function and programming. The unit is designed
with an on unit contreolboard as well. For further details please refer to the Operation
Manual, Appendix A.
1.6 Outdoor Unit
The FBF 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.
●Axial fan.
●Outdoor coil with hydrophilic corrugated fins for RC units.
●Outlet air fan grill.
●Service valves” flare” type connection.
●Interconnecting wiring terminal block.
●Electrical phase protector (on 3PH models).
●Advanced TYPHOON PCB.
1.7 Tubing Connections
Flare type interconnecting tubing to be produced on site.
For further details please refer to the Installation Manual, Appendix A.
1.8 Accessories
ASK (All Season Kit):
For low ambient working conditions in cooling, an ASK can be installed.This kit allows
cooling operation down to outdoor temp of -10 ºC by gradually controlling the outdoor
fan speed motor.
RCW Wall Mounted Remote Control
The RCW1/ RCW2 remote control is a wall mounted remote controller, for multi indoor
unit applications and functioning
For further details please refer to Optional Accessories, Chapter 14.
1.9 Inbox Documentation
