Storage
If the fan is stored for any length of time prior to installation,
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, outlet and belt tunnel opening to prevent the
accumulation of dirt and moisture in the housing
• Periodically rotate the wheel and operate inlet vane damp-
ers (if supplied) to keep a coating of grease on all internal
bearing parts
• Periodically inspect the unit to prevent damaging conditions
Installation
QMX, QMX-HP and QMX-XP can be mounted horizontally
or vertically to a floor or a ceiling in various motor positions
and discharges.(See Mounting Detail) QMXU, QMXHPU,
QMXE, QMXHPE, QMXS and QMXHPS are all designed to
be roof mounted on typical roof curbs. The QMX-LE or QMX-
VP units, however, should not be mounted on sheet metal roof
curbs, but supported by integral members of the roof structure,
designed and constructed by others per local requirements
and environments.
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 separately
due to height limitations. These motors and drives will require
field installation.

Isolation Installation
To help prevent vibration and noise from being transferred
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
counterclockwise several turns at a time alternately on
each isolator until the fan weight is transferred onto the
isolators 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
C
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.
Ceiling Mounted Spring and Rubber-in-Shear (RIS)
C
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.

NOTICE! Although a certain amount of vibration is
inherent in operating fans, extreme vibration is a
serious problem that may cause structural and me-
chanical failure.
