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 inlet vane dampers (if supplied) for free opera-
tion of all moving parts.
• Record on the Delivery Receipt any visible sign of
damage.
Handling
Lift the fan by lifting lugs. 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.
• Cover the inlet and outlet, and belt tunnel opening to
prevent the accumulation 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.
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.
• Periodically inspect the unit to prevent damaging condi-
tions.
Installation
QMX and QMX-HP can be mounted horizontally or verti-
cally to a floor or a ceiling in various motor positions and
discharges. QMXU, QMXU-HP, QMXE, QMXE-HP, QMXS
and QMXS-HP are all designed to be roof mounted on typi-
cal roof curbs. The QMXLE or QMXLE-HP units, however,
should not be mounted on sheet metal roof curbs, but sup-
ported by integral members of the roof structure, designed
and constructed by others per local requirements and envi-
ronments.
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.
Isolation Installation
To help prevent vibration and noise from being transferred
to the building, isolators are recommended.
Floor Mounted Spring Isolators
a. Mount fan on isolation base or rails (if supplied).
b. Elevate fan (or isolation base) to operating height and
insert blocks to hold in position.
c. 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.
Personal Safety
Disconnect switches are recommended. Place the
disconnect switch near the fan in order that the
power can be swiftly cut off in case of an
emergency, and in order that maintenance
personnel are provided complete control of the
power source.
NOTE
Although a certain amount of vibration is inherent
in operating fans, extreme vibration is a serious
problem that may cause structural and mechanical
failure.
