Notes:

1. Areas shaded in blue indicate factory setting of rpm.

2. Areas shaded in grey indicate operating range outside the standard motor. Shift to larger motor size in this area.

3. Internal static pressure is based on pressure drops through evaporator coil and fan casing only.

4. Internal static pressure is based on pressure drops through evaporator coil, fan casing and 1” flat filter (if specified).

5. The shown rpm range is with standard pulleys combination.

Installation and Commissioning

• Install the unit in such a location which is flat and strong enough to support its weight.

• Provide a trap of over 2" (50mm) in the drain piping for water seal.

• All field wiring must comply with applicable local and national codes.

• Connect supply and return ducts as shown.

• Service spacing should be provided as shown in the figure. If any obstacles are around the unit, distributed air is short-circuited
so that the unit stops frequently and access to the unit is difficult for inspection and aftersales services.
