Duct air conditioners with universal outdoor units FORT series

ROVER FORT duct indoor units are placed behind the false ceiling. Cooled air distribution is carried out through an air duct system. In this case an indoor unit and air ducts are hidden from eyes.

The return duct can be connected from the back of the unit or from the bottom depending on installation site.ROVER FORT duct  is easy to install.

Duct air conditioners with universal outdoor units of the FORT series are represented by models: 18 000 BTU (RU0ND18BE), 24 000 BTU (RU0ND24BE), 36 000 BTU (RU0ND36BD), 48 000 BTU (RU0ND48BD), 60 000 BTU (RU0ND60BD).

* The amount of freon is indicated for the pipe length of no more than 5 m. With an increase of the pipe length, it is necessary to charge the additional refrigerant at the rate of 15 g per 1 m for the 1/4″liquid pipe and 30 g per 1 m for the 3/8″liquid pipe.

** Cut-off current is not less than 7 In (In - rated current), leakage current is not more than 30mA, shutdown characteristic is «C». It is allowed to install the circuit breaker and RCD with the same capacity in series.

The table shows data for temperature conditions in accordance with ISO 5151-94:
- cooling mode inside 27 °C (DB)/19 °C (WB), outside 35 °C (DB)/24 °C (WB)
- heating mode inside 20 °C (DB)/15 °C (WB), outside 7 °C (DB)/6°C (WB)
