Note: Sound level is measured at a distance of 8 ft. from the return air grille. Measurements are for a typical furnished and
carpeted hotel suite. CFM in the above chart is approximate. Airflow is dependent on the number of coil rows, coil fins per inch, the amount of condensate on the fins, supply voltage, motor manufacturer, supply air configuration, filter cleanliness and altitude.

• Heaters are wired for single stage operation.
• An auto-reset high limit device is included.
• Power connection is single point.
• The heater is located in the reheat position relative to the cooling coil.
• The fan coil unit does not include a fuse or fusible type disconnect. Motor sub-fusing as per electrical code.

Components and Options
Requirements of Standards: UL 1995 and CSA C22.2 No.236
• If the value of the calculated rating does not equal a standard current rating of overcurrent protective device, the mark ed maximum rating shall be the next lower standard rating.
• Exception No. 1: The marked maximum rating of the overcurrent protective device shall be the standard rating next higher than the computed value if the next lower standard ratings is less than 125 percent of the current rating of an electric heater load, when the unit includes an electric heater.
• Exception No. 2: if the computed value of the overcurrent protective device is less than the minimum ampacity of the supply circuit, the marked rating of the device shall be increased to the largest standard overcurrent protective device rating appropriate for the marked minimum circuit ampacity.
• Exception No. 3: If the marked minimum circuit ampacity does not correspond to a standard protective device rating, the next higher standard rating of the protective device may be marked.
