4. Fan Installation
PNEG-010 Vane Axial Fan 13
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 blade rotation is in the
direction that the decal on the fan housing illustrates. If the blade 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.
Use a #6 or approved size bare copper ground wire. Install a 5/8" diameter 8' long
copper-clad ground rod, 2' away from the foundation and 1' below the surface of the
ground or in accordance with local requirements.
