Lo - Static fan coil units use centrifugal double inlet double

permanent split capacitor motor. These motors have integral
thermal protection, low temperature rise, are highly efficient,
have high power factor and operate almost noiselessly with
permanent lubricated sleeve bearings.

Motor Technical Data

All motors used in low Static Fan Coil Units are inherently
protected by means of thermal cut-out embedded in the Figure 1
winding. This thermal cut-out is calibrated to trip out when the
winding reaches a pre determined temperature. The thermal
cut out will automatically reset when the temperature returns
to a safe limit.

Notes: Table 7

Chilled water capacity ratings are based on nominal air flow rate; air entering temperature DB/WB 80/67oF (26.7/19.4oC), 45oF
(7.2oC) entering chilled water temperature and 10oF (5.5oC) water temperature rise.
For conditions other than rated, use SKM FCU Computer Selection Software.

Notes:
Chilled water capacity ratings are based on nominal air flow rate; air entering temperature DB/WB (78/65)oF (25.6/18.3oC), 42oF
(5.5oC) entering chilled water temperature and 58oF (14.4oC) leaving water temprature.

For conditions other than rated, use SKM FCU Computer Selection Software.
