Installation - COOK TMX Installation, Operation And Maintenance Manual

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 Lubrication, page 6). Store the fan in its
original crate and protect it from dust, debris and weather.
• Cover the inlet, and outlet opening to prevent the accu-
mulation of dirt and moisture in the housing
• Periodically rotate the wheel and operate inlet vane
dampers (if supplied) to keep a coating of grease on all
internal bearing parts
• Periodically inspect the unit to prevent damaging
conditions

Installation

TMX can be mounted horizontally or vertically to a floor
or a ceiling in various motor positions and discharges.
Most motors are shipped mounted on the fans with belts
and drives installed. However, extremely heavy motors are
shipped separately, and some motors are shipped sepa-
rately due to height limitations. These motors and drives
will require field installation.
NOTICE! Although a certain amount of vibration
is inherent in operating fans, extreme vibration is
a serious problem that may cause structural and
mechanical failure.
Isolation Installation
To help prevent vibration and noise from being trans-
ferred to the building, isolators are recommended.
Floor Mounted Spring Isolators
1. Mount fan on isolation base or rails (if supplied).
2. Elevate fan (or isolation base) to operating height and
insert blocks to hold in position.
3. Position isolators under the fan and vertically align by
inserting leveling bolt through mounting holes in the
fan or the base. The isolator must be installed on a
level surface.
4. Adjust the isolators by turning the leveling nut counter-
clockwise several turns at a time alternately on each
isolator until the fan weight is transferred onto the iso-
lators and the fan raises uniformly off the blocks. Then
remove the blocks.
5. Turn lock nut onto leveling bolt and secure firmly in
place against the top of the mounting flange or frame.
6. Secure isolators to mounting surface.

Floor Mounted Rubber-In-Shear (RIS) Isolators
1. Mount fan on isolation base or rails (if supplied).
2. Elevate fan to provide room to insert isolators between the
fan and foundation and block in position.
3. Position isolators under fan and secure bolts.
4. Remove blocks and allow fan to rest on floor. Isolators
must be installed on a level surface (leveling should not be
required).
5. Secure isolators to mounting surface.

Isolators
1. Elevate fan to operating height and brace.
2. Attach threaded rod to overhead support structure directly
above each mounting hole. Rod should extend to within a
few feet of fan.
3. Attach isolator to end of threaded rod using a nut on each
side of isolator bracket.
4. Insert another section of threaded rod through the fan
mounting hole and isolator.
5. Attach two nuts to threaded rod in isolator.
6. Place adjusting nut and locking nut on threaded rod near fan
mounting bracket.
7. Alternately rotate adjusting nut at each mounting location
until the fan weight is uniformly transferred to the isolators.
Remove bracing.

Duct and Damper Installation
Efficient fan performance relies on the proper installation of
inlet and discharge ducts as well as dampers. Be sure your fan
conforms to the following guidelines and allows three duct diam-
eter of straight duct before placing an elbow or damper. Clear-
ance is also required on the inlet and outlet for maintenance
such as pulley or bearing replacement.
Non-Ducted Inlet Clearance
If your fan has an open inlet (no duct work), the fan must
be placed one effective wheel diameter away from walls
and bulkheads.

Free Discharge
Avoid a free discharge into the plenum. This will result in
lost efficiency because it doesn't allow for a static regain.
