PNEG-119 Inline Centrifugal Fan
Installation
1. Be sure that the disconnect and the fan are well grounded. See machine to earth ground on
IMPORTANT: All fans with controls use 120 volt control circuit. Neutral must be supplied on
230 volt 1 and 3 Phase models for unit to operate.
2. Rotate the fan blade to be sure that it revolves easily and does not rub the housing.
3. Check all fasteners on motor mounts, fan blades and other bolted items to make sure they are tight.
If any are loose, check for proper clearance and re-tighten fasteners. They may have loosened
in shipping.
4. Fans should be mounted to set level and solid. It may be necessary to shim one or more corners of
the foot mount to achieve a solid mounting. Fans not solidly mounted and properly shimmed may
have excess vibration in them.
5. Check and re-tighten all electrical connections. They may have loosened in shipping.
WARNING
Always disconnect and lock out power before working on or around fan.
