Need help?Do you have a question about the COOK XLWH/XMWH and is the answer not in the manual?
Read this publication and supplemental documents before installation or maintenance.
Inspect the unit and accessories for damage or shortage upon receipt.
Lift fans by attachment to the power assembly or shipping carton, not by shaft or motor.
Coat shafts with grease, store in original crate, protect from elements.
Wall opening size varies by mounting type; refer to submittal drawings for dimensions.
Mount motors (5 HP+) and heavy motors to the motor mounting plate.
Disconnect power, use lockout/tagout, place disconnect switch near fan.
Adjust belt tension by moving the motor plate; proper tension has 1/4" deflection per foot.
Do not change pulley pitch diameter to adjust tension; this changes fan speed.
Align pulleys by loosening motor pulley setscrew and moving pulley on shaft.
Insert fan into wall opening, secure with fasteners, ensure motor base is below fan shaft.
Follow local ordinances, NEC, wiring diagrams; ensure correct voltage and frequency.
Label circuits, identify closed switches, follow safety practices.
Extend wires, prevent excess wire entry into fan area.
Remove end panel or extend wires through side panel for access.
Remove end guard, drill hole for wires, restrain incoming wire.
