Handling
Units shipped completely assembled may be lifted with
slings and spreader bars. Lift the fan in a fashion that
protects the fan and fan coating from damage. Never lift a
fan by the inlet or discharge flange, shafting or drives, motor,
impeller, motor base or housing, or in any other manner that
may bend or distort parts.
Lifting Instructions
Fans are designed to be lifted and moved as a single
module. Cook does not recommend lifting connected fan
modules unless the fan module(s) is supported on a common
base.
1. Carefully remove any crate and packing materials.
2. Place the bottom fans onto the mounting structure using
the recommended lifting points as shown. Lift each fan
individually into position.
Storage
If the fan is stored for any length of time prior to installation,
store it in its original shipping crate and protect it from dust,
debris and the weather.
Short Term Storage
If fan installation is delayed, store the unit in a protected
area. Protect the motor bearings from moisture and vibration
(or shock loading).
Long Term Storage
If a fan is to be stored for any length of time and the
bearings are re-greasable, the motor bearings should
immediately be filled with grease while rotating the fan and
then the bearings should be re-greased and rotated monthly.
This will prevent moisture, which condenses within the
bearing, from corroding the raceways.
Storage Procedures
Fans should be stored indoors whenever possible where
control over temperature, humidity, shock and dust is
reasonably maintained. If units are to be stored outside, they
should be covered with a water-resistant material. Stored
equipment should be on a clean, dry floor or blocked up off
the ground to prevent unit from setting directly on the ground.
Periodic Check:
On a monthly interval, the equipment should be checked to
ensure that it has remained in an acceptable stored condition.
The fan and motor should be rotated several times by hand.
The fan impeller should be left at approximately 180 degrees
from that of the previous month to prevent damaging the
motor bearings.
Unit Start Up
When the unit is removed from storage, all grease should
be purged and replenished with fresh grease. The following
list should be adhered to insure proper operation:
Electrical Interferences Hazard:
Electrical Hazard:
Verify that proper safety precautions are followed: electrical power
must be locked off..
Check fan mechanism components:
• System connections are properly made and tightened.
• Impeller and fan surfaces are clean and free of debris.
• Rotate the impeller by hand to verify it has not shifted in
transit.
Check fan electrical components:
• Motor is wired for proper supply voltage.
• Motor was properly sized for power
• Motor is properly grounded.
• All leads are properly insulated.
• Trial “bump”:
• Turn on power just long enough to start assembly rotating.
• Check rotation for agreement with rotation arrow.
Preferred lifting method:
Eyebolt with washers and nut
Alternate lifting methods:
S-Hook
Safety Hook
Lifting Points
– 5/8” diameter holes
