The associated intake damper also opens. When the pump motor shuts down, or the room U
temperature drops below 100 F, the associated exhaust fan stops and intake damper closes. Exhaust fan AH-E-29 will operate whenever ele'ctrical equipment room te.Tperature exceeds 75 F.
The unit heaters will start if ambient temperature U
falls below the associated thermostat setpoint.
4.3 Shutdown 4.3.1 To shut down pump room exhaust fans turn each fan selector switch at panel 321 to 0FF.
