3. Leveling and Shimming
Use slotted shim stock beneath the bottom array as
needed. Spaces greater

Electrical Connections
Before electrical connections are made, the supply voltage, phase and ampere capacity must be checked for
compatibility with the fan motor. In addition, the supply wiring must be properly fused and conform to local and
national electrical codes. If the unit is supplied with a safety disconnect switch, ensure proper wiring to the fan
motor. Be sure the disconnect is switched to the “OFF” position before connecting supply wires. If no disconnect
is supplied, ensure the supply wire is not live before connection. Supply wires are then connected to the optional
safety disconnect switch (if supplied) or motor.
