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 inside the
outdoor unit. 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 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 Optional Accessories, Chapter 15.
