INSTALLATION
Fig. 1 Lifting Point (4 places)
LIFTING - Attach a suitable chain or strap to the points depicted in Fig. 1. The fan should never be lifted by the motor, tie down points, belt tube, damper frame, windband or accessories.
Carefully lift the fan to the roof curb and install fasteners in all holes provided in the unit base. The windband need not be removed for the lifting operation.
ELECTRICAL CONNECTIONS - The electrical supply must be compatible with the fan motor voltage, phase and amperage capacity. The electrical supply line must be properly fused and conform to local and national electrical codes.
For direct drive units, the electrical supply may be routed internally and exit through a hole provided in the fan housing if an optional service disconnect switch is provided.
For belt drive units, the electrical supply line may be routed internally and exit the fan housing through a hole provided below the belt tube opening. The electrical supply line should then be either: (1) connected to an optional service disconnect switch, or (2) wired directly to the motor.
For belt drive units in continuous high temperature installations, the electrical supply must be kept out of the airstream. This means bringing the supply lines off the roof deck not through the fan. The electrical supply line should then be either: (1) connected to an optional service disconnect switch, or (2) wired directly to the motor.
For belt drive units in emergency smoke removal installations, the electrical supply must be kept out of the airstream. They may also require an isolated power supply so that if power is cut to the building in the event of a fire, the fan will continue to operate. Check the local and national electrical codes for emergency smoke removal fans.
** WARNING **
Disconnect and secure to the “off” position all electrical power to the fan prior to inspection or service.
Caution must be used when working around the fusible link damper lifters. They contain preloaded springs and may open the dampers unexpectedly.
