COOK IMH - Manual

Installation
Most motors are shipped mounted on the fans with belts
and drives installed. However, extremely heavy motors and
drives are shipped separately. These motors and drives will
require field installation. Please refer to pages 3-5.
Foundation
This fan requires a strong, level foundation of reinforced
poured concrete. A correctly designed concrete foundation
provides the best means for mounting floor units. The foun-
dation’s size is determined by fan size, motor size and posi-
tion, and the specific location of the installation.
Use the following guidelines to calculate foundation size:
• The overall dimensions of the foundation should extend
at least 6 inches beyond the outline of the fan and its
motor.
• The weight of the foundation should be 2 to 3 times the
weight of the unit and its motor.
Isolation
Isolation Base
To prevent vibration and noise from being transferred to
the building isolators are recommended. Arrangement 1
fans require an isolation base to effectively isolate the fan
system: fan, base, motor, drive, guards, etc. Bases must
have sufficient rigidity to resist belt pull and prevent drive
distortion which can lead to excessive belt and bearing
WARNING
This unit has rotating parts. Safety precautions
should be exercised at all times during installation,
operation, and maintenance.
ALWAYS disconnect power prior to working on fan.

Receiving and Inspection
Carefully inspect the fan and accessories for any dam-
age and shortage immediately upon receipt of the fan.
• Turn the wheel by hand to ensure it turns freely and
does not bind.
• Inspect dampers (if supplied) for free operation of all
moving parts.
• Record on the Delivery Receipt any visible sign of
damage.
Handling
Lift the fan by the base or lifting eyes. Never lift by the
shaft, motor, or housing.
Storage
If the fan is stored for any length of time prior to installa-
tion, completely fill the bearings with grease or moisture-
inhibiting oil (refer to Lubricants on page 6). Also, store the
fan in its original crate and protect it from dust, debris and
the weather.
Outdoor Storage
To maintain good working condition of the fan when it is
stored outdoors, follow the additional instructions below.
• Coat the shaft with grease or a rust preventative com-
pound.
• Wrap bearings for weather protection
• Cover the inlet and outlet of the fan to prevent the accu-
mulation of dirt and moisture in the housing.
• Periodically rotate the wheel and operate dampers (if
supplied).
• Periodically inspect the unit to prevent damaging condi-
tions.
