Literature Change History
QFNA-IOM-1 (August 1997)
Manual supersedes FAN-IM-3
(975), reflecting ABU support of
the Q fans and Super Q fans.
General update.
About this Manual
This manual describes proper
installation of Model Q Fans and
Super Q II Fans.
Note: The installation and
servicing of the equipment
referred to in this booklet should
be done only by qualified,
experienced technicians.
Model Q fans are shipped
assembled except for some motor
and drive selections that are not
mounted for shipping reasons or
are intended for field installation at
customer request.
Accessories are mounted to the
fan at the factory with the following
exceptions:
A. Inlet Vane Option (Shipped
from mfg. to job site)
B. Silencer Option (Shipped from
mfg. to job site)
C. Flex Duct Option (Shipped with
fan)
D. Vertical Mounting Leg
Option (Shipped with fan)
E. Isolator Option
(Shipped with fan or from mfg.)
These accessories have their own
installation instructions which are
shipped with the accessory.
Trane Model Q fans and Super Q
II Fans are dynamically balanced,
properly aligned, and lubricated
before leaving the factory. These
Procedures, however, do not
guarantee that the fan will be
ready to operate on receipt.
Damage and misalignment can
occur due to rough handling
during shipment and installation.
Follow all instructions in this
manual to assure a successful
installation. Failure to follow
these instructions may void the
warranty.
THIS MANUAL SHOULD BE
KEPT WITH THE FAN UNIT
SINCE IT CONTAINS
INFORMATION FOR PROPER
MAINTENANCE AND
TROUBLESHOOTING.
Warnings and Cautions
Notice that WARNINGS and
CAUTIONS appears at
appropriate intervals throughout
this manual. WARNINGS are
provided to alert installing
contractors to potential hazards
that could result in injury or death,
while CAUTIONS are designed to
alert personnel to conditions that
could result in equipment damage.
Your personal safety and the
proper installation of this unit
depend upon the strict observance
of these precautions.
Observe the following warnings,
cautions and all warning labels on
the unit:
WARNING!
ROTATING PARTS
DISCONNECT ALL ELECTRIC
POWER INCLUDING REMOTE
DISCONNECTS BEFORE
SERVICING. SECURE DRIVE
SHEAVES TO ENSURE ROTOR
CANNOT FREEWHEEL.
Failure to disconnect power
before servicing can cause
severe personal injury or death.
Note: Re-connect all grounding
devices. All parts of this product
capable of conducting electrical
current are grounded. If grounding
wires, screws, straps, clips, nuts
or washers used to complete a
path to ground are removed for
service, they must be returned to
their original position and properly
fastened.

General Information

All Model Q and Super Q II fans
are shipped on skids to minimize
possible damage in transit.
Caution:
NEVER LIFT A UNIT BY THE
BEARING BRACKETS, MOTOR
BRACKETS, OR OTHER
ACCESSORIES. NEVER
FORKLIFT THE UNIT BY THE
HOUSING. Failure to handle
properly will damage the unit.
Fan sizes 16-44 can be lifted
using the lifting holes in the
square outer frame. If a forklift is
used, lift only under the skids or
frame, being especially careful for
units with special protective
coatings.
Fan sizes 49-60 should be rigged
for lifting and handling by securing
chains or cables through the front
and rearmost mounting supports
and under the horizontal stiffening
angles as shown in Figure 1.
Storage
The following criteria should be
met when storing the unit.
Note: Protect the unit from the
elements.
Where outside storage is
necessary, several precautions
are needed.
• First cover the inlet bearing and
drive opening, then place unit in
an area with good drainage and
cover with a tarp if possible.
• Do not use plastic to completely
cover the unit at the risk of
trapping condensation. This
type of covering can cause
excess moisture, condensation
and rusting.
• DO NOT STACK FANS.
FAN SIZES 49-60 THAT SHIP
WITH AN INLET BELL MUST
REMAIN ON THE SHIPPING
SKID UNTIL READY TO BE
INSTALLED ON ISOLATORS.
The inlet bell extends below the
bottom frame of the fan and can
be damaged if set on the floor
without skids.
For extended storage or storage
under severe conditions:
• As often as once a month,
purge the bearings with fresh
grease to prevent moisture or
dirt from accumulating in the
bearing.
• See Maintenance Section of
this manual.
QFNA-IOM-1 9
Shipping, Rigging and Handling
Figure 1—Typical Fan Unit Shipped with Rigging
(Sizes 49-60)

Provide a Foundation
Most units will be mounted to or
hung from a concrete structure. If
mounted to a steel structure, the
mounting structure should be
welded. Table 2 refers to unit
weights.
Isolate the Fan
Isolation should be used to
prevent noise and vibration from
being transmitted to the building.
Arrangement 9: For units size
16-44, Class I and II
Mount directly to four flexible
isolators for either floor or ceiling
mounting. Use rails for wall
mounting. For vertically-mounted
fans, provide mounting legs to
which isolators are mounted.
Arrangement 9: For units size
49-60, Class I and II
Mount directly to eight isolators
when used with a steel or
concrete base. Eight bolts are
used to mount the fan to the base
in holes pre-drilled. These sizes
must be mounted horizontally.
When ceiling suspension is
required, the fan must be set on
an integral base which is hung
from the ceiling.
Arrangement 1: For units size
27-44, Class I and II
Use an integral steel or concrete
base rather than individual
isolators. Mount the fan
horizontally as shown in Figure 2.
Arrangements 1 and 9: For
units size 16-44, Class Ill
Provide a rigid integral steel base
or, preferably, an inertia pad.
Mount these fans horizontally.
Note: For some applications
involving large fans and high
pressures, thrust restraints may
be required. When used, mount
them on the fans exterior frame
members at the horizontal
centerline.
Clearances
Allow sufficient clearance around
the equipment to provide ample
room for servicing and
maintenance. Inlet screen may be
used if the fan has an unducted
inlet. Recommended minimum
clearance is no less than 1/2 the
fan wheel diameter away from a
wall or obstruction.
