CAUTION: When performing HVAC operations, the damper indicator lights should show the damper fully closed (stop - green) or open (run - red) prior to performing the next step in the sequence. NOTE: All components should be cycled to the off/closed position if the system has tripped due to a power failure. EQUIPMENT

Exhaust Fan, V-1 RUN (Red) RUN (Red; Refer to Note #4 below) ON (Refer to Note #5 below) Note 1) The room thermostat cycles the refrigeration unit (S-3) or heating coils (HC) as thermostat demands, while the air handler fan runs continuously. Note 2) Damper D-3 is interlocked with the Air Handler Fan S-1 and will not open unless S-1 is running. Note 3) HEPA Filter Fan F-1 and Damper D-2 are interlocked. Fan F-1 will not operate without D-2 open. If Damper D-2 is closed with F-1 operating, then fan F-1 will trip off-line. Note 4) The Computer Room HVAC operates independently of the main LEOF air condition unit. Switch S-2 is located on the ventilation panel and Switch S-4 is located on the MCC in the Electrical/Mechanical Equipment Room labelled "Computer Room Indoor HVAC Unit". Both switches must be ON for the system to operate. Note 5) The ON/OFF switch for fan V-1 is in the Custodian's Closet, which is located next to the men's room and normally locked. Get LEOF key (NAB-110) from Security. The operating switch is the left switch on the double switch plate. Exhaust Fan V-1 can only be operated if:

1) Air Handler S-1 is RUN (Red).
2)

Damper D-3 is RUN (Red).

3) The ON/OFF switch for V-I is ON.
