3. Installation
16 PNEG-163-08 Centrifugal Fan
Check this voltage before starting unit. If voltage is not within 105 VAC-125 VAC, check for proper
voltage on L2 or L3 and move to appropriate leg. If voltage is not acceptable, install a 1/4 KVA
step-down transformer.
NOTE: Grounded B and some open delta power supplies will require this transformer kit.
Final Check
Check to make sure all safety guards are in place and not damaged. Replace damaged parts.
Check to make sure all decals are visible and not damaged. Replace damaged decals.
Check to make sure all control boxes are closed and no wiring is exposed.
Test Run
When the fan is completely installed, the unit will need to be checked for proper rotation. Provide power
to the fan controls and start the fan momentarily. Make sure that the fan wheel rotation is in the direction
that the decal on the fan housing illustrates. If the decal is missing, note that the wheel should operate
counterclockwise when viewed through the inlet guard on standard construction fans. If the wheel is
rotating the wrong direction, have the electrician correct the wiring.

CAUTION
The voltage between L1 and N must be 115 VAC. Any other voltage will cause
damage to equipment.
