Domex, Centrifugal Roof, Direct & Belt Drive Exhausters
Description
PennBarry roof-mounted ventilators are belt-driven centrifugal exhausters designed to
meet air delivery requirements where steady exhaust is needed under moderate static
pressure. Housings are of spun aluminum construction with built-in bird screen. Ventilators are furnished with self-aligning, pre-lubricated, ball bearing pillow blocks, spark
proof aluminum wheels, and aluminum backdraft damper.
Receiving and Handling
PennBarry fans are carefully inspected before leaving the factory. When the unit is
received, inspect the carton for any signs
of tampering. Inspect the unit for any damage that may have occurred dur-ing transit
and check for loose, missing or damaged
parts. Mishandled units can void the warranty provisions. If units are damaged in
transit, it is the responsibility of the receiver
to make all claims against the carrier. PennBarry is not responsible for damages incurred during shipment.
Avoid severe jarring and/or dropping.
Handle units with care to prevent damage
to components or nishes. If the unit is
scratched due to mishandling, the protective coating may be damaged. Incorrect
lifting may damage the fan and void the
warranty.
Storage
Long-term storage requires special attention. Store units on a level, solid surface,
preferably indoors. If outside storage is
necessary, protect the units against moisture and dirt by encasing the cartons in
plastic or in some similar weatherproof
material. Periodically inspect units and
rotate wheels to spread bearing lubricant.
Failure to rotate wheels results in reduced
bearing life and may void the manufacturer’s warranty. If the unit will be stored for
an extended time, remove belts. Belts
which remain under tension in a stationary
position for extended periods are like-ly to
have a reduced operating life.
Unpacking
Place the carton in an upright position and
remove the staples or use a sharp (knife
edge) tool to carefully cut or scribe the
sealing tape on both sides at the top of the
carton. Open carton aps. Remove any
cardboard and wooden ller pieces, as
well as loose components or accessories
shipped with the unit.
Carefully remove the unit from the carton.
Inspect the unit for any damage that may
have occurred during transit and check for
loose, missing or damaged parts.
Installation
!
NOTE
Zones, unit must be installed per
instructions on page 4.
INSTALLING MOTORS
In some instances, large frame motors
may be shipped loose and require eld
mounting. If so, carefully review motor
mounting installation procedures per Figure 1, Figure 2 and Figure 3.
INSTALLING THE DAMPERS:
ROOF MOUNTING
When required, install dampers prior to
mounting the unit on the curb or frame.
Secure dampers to the inside of the roof
opening (preferred) or curb without undue
twisting, which may distort the damper
frame. Damper frame must be reasonably
level on all sides. Check for free operation. If dampers are motor operated type,
ascertain that proper voltage is impressed
on motor terminals.
POSITIONING AND RUNNING POWER
LINES: ROOF MOUNTING Power is nor-
mally brought from within the building
through proper conduit lines and placed
inside one corner of the curb. Feed power
line through the clearance hole provided
in the damper, if furnished, and in turn
through the ventilator to the discon-nect
switch, if furnished, and motor.

When power lines are brought up to the
unit, provide a generous amount of slack
to allow for motor adjustments and to permit movement of motor for belt tension adjustments. Ground motor adequately and
securely. Protect power lines from sharp
objects. Do not kink power line or permit it
to contact hot surfaces, chemi-cals, grease
or oil. Use only UL recog-nized electrical
parts, rated for proper voltage, load and
environment. Check motor name plate.
ANCHORING AND SECURING THE
VENTILATOR: ROOF MOUNTING
Whenever possible, anchor the fan by fastening through the vertical portion of the
mounting ange. The type, size and number of fasteners depends upon the unit size
and curb construction. If code or specication prescribes fastening through the top
(vertical portion) of the mounting ange,
use neoprene or lead washers under the
head of each fastener.
Guy down large units installed in areas
subject to high winds or unusual eld con-
ditions. If the installer removes any ventilator parts to facilitate installation or electrical connections, reassemble all parts by
replacing all spacers, washers, nuts, bolts,
fasteners and components exactly as they
were found prior to removal. Draw all fasteners tight and secure. Fasteners should
be protected against corrosion.
MOTOR INSTALLATION PROCEDURES
1. Install motor pulley assembly (bracket if
provided - type 3) with hardware provided through holes in motor mounting plate/frame. Keep driven pulley
and drive pulley in line. (Do not tighten
hardware).
2. Install belt over drive and driven pulleys, pull up on motor mounting plate/
bracket until belt is tight. Tighten motor
plate hardware.
3. Wire motor or plug harness connec-tor
(from motor if equipped) into terminal
socket at end of junction box. Unit is
now ready to test to check for smooth
operation.
4. See belt adjustment label, and Fig.
4, for more details.
5. Check for proper wheel rotation.
Start-Up and Operation
Carefully inspect the unit before start-up.
All motor bearings should be properly lubricated and all fasteners should be securely tightened. Rotate centrifugal wheel
by hand to insure free movement.
Before placing hand
on centrifugal wheel
or belts, lock out power source.) Check all
set-screws and keys. Tighten when necessary.
Check condition of belts and the amount
of tension prior to start-up. DO NOT overtighten, as bearing damage will occur.
Recommended belt tension should per-
mit deection of 1/64” per inch of span.
Exercise extreme care when adjusting
belts as not to misalign the pulleys. Any
misalignment will cause a sharp reduction
in belt life and produce squeaky, annoying
noises. On units equipped with two groove
pulleys, adjust all belts with equal tension.
Belts must be adjusted after approximately 40 hours of operation.
Figure 4: Pulley Alignment & Tension
WRONG WRONG CORRECT
Not to exceed 1/64” per inch of span
Whenever belts
are removed or
installed, never force belts over pulleys
without loosening motor rst to relieve
belt tension.
Make sure inlets and approaches to the
unit are free from obstruction. To assure
maximum air movement, make sure adequate supply air is available to ventilated
space.
Before putting fan into operation, complete the following check list:
a. Turn off and LOCK OUT the power
source.
b. Make sure installation is in
accordance with manufacturer’s instructions.
c. Check and tighten all fasteners.
d. Spin centrifugal wheel to see
if rotation is free.
e. Check all set-screws and keys:
tighten if necessary.
f. Torqued set screws have a colored
Torque Seal mark indicating the correct torque has been applied.
g. Check belt or direct drive coupling
for alignment (use recommended
belt tension gauges).
h. Check belt for proper
sheave selection.
i. Make sure there is no foreign or
loose material in ductwork leading to
and from fan or in the fan itself.
j. Properly secure all safety guards.
k. Secure all access doors to fan
and ductwork.
l. Check line voltage with
motor nameplate.
m. Check wiring.
(On single phase mo-
tors, the terminal
block must be set up in accordance with
the nameplate instructions and/or wiring
diagram. This set up must match the line
voltage. If the motor is multi-speed or
multi-voltage, the winding leads must be
grouped and connected as shown on the
motor wiring diagram. The line voltage
must correspond with proper grouping
of motor leads. The wiring diagram must
be followed explicitly or serious motor or
starter damage will occur.) Don’t operate
at RPM higher than catalog.
The ventilator has been checked at the factory prior to shipment for mechanical noises.
If mechanical noises should develop:
a. Check rotating components
for adequate clearance (wheel align-ment pr
cedures are on page 7) and direction of rotation. CCW looking from drive side.
b. Check proper belt tension and pulley
alignment.
c. Check installation and anchoring.
d. Check fan bearings.
Switch on electrical supply and allow fan to
reach full speed.
Check carefully for Correct rotation of the
centrifugal wheel.
Incorrect rotation
overloads motor
severely and results in serious motor damage. To change rotation of three phase
units, interchange any 2 of the 3 line leads.
On single phase units, change the terminal
block set-up following the wiring diagram on
the motor.

Operation & Maintenance Manual
2. Check motor and bearing
temperatures for excessive heat.
Use care when touch-ing
the exterior of an operating motor. Modern motors normally run
hot. They are designed to operate at higher
temperatures. This is a normal con-dition
but they may be hot enough to be painful or
injurious to the touch.
If any problem is indicated, TURN OFF
POWER TO UNIT IMMEDIATELY. Lock
out the electrical supply, check carefully
for the cause of the trouble and correct
as needed. Even if the fan appears to be
operating satisfactorily, shut down after a
brief period and check all fasteners, setscrews and keys for tightness.
During the rst eight (8) hours of opera-
tion, check the fan periodically for excessive vibration or noise. At this time, also
check motor input current and motor bearing temperatures to insure that they do not
exceed manufacturer’s recommenda-tions.
After eight hours of satisfactory operation,
shut down the fan and lock out the electrical power to check the following items and
adjust if necessary:
a. All set-screws, keys and fasteners.
b. Drive coupling alignment.
c. Belt alignment.
d. Belt tension.
Maintenance
Do not attempt maintenance on fan until
the electrical supply has been completely
disconnected. If a disconnect switch has
not been provided, remove all fuses from
the circuit and lock the fuse panel so they
cannot accidentally be replaced.
Lubrication is a primary maintenance
responsibility. Check all bearings periodically. Inspect belts for tightness. If the fan
is installed in a corrosive or dirty atmosphere, periodically clean the impeller, inlet
and other moving parts.
FAN SHAFT LUBRICATION
Fan shaft bearing pillow blocks are furnished in either the prelubricated sealedfor-life type or the greasable type depending on what was ordered. The prelubricat-ed
type requires no servicing for 7 to 10 years
of normal use and the greasable type are
factory greased eliminating the need for
greasing initially. Follow the lubri-cating
schedule recommended by the fac-tory.
When required, apply grease while the
shaft is rotating. This practice should not
supersede any safety considerations.
Use low pressure grease
guns tend to blow out or unseat bearing
seals, leaving the bearing open to collect
grime, dust and foreign particles.
guns only. High pressure
LUBRICATION SCHEDULE
Always follow the bearing manufacturer’s
recommended lubrication schedule. If
none is available us the following general
schedule.
a. Under average conditions where ambient temperatures do not exceed 120°F.,
lubrication is required 1 to 2 times a year.
b. Under dirt laden atmospheres or where
there is a temperature range of 120°F to
150°F, lubrication is required from 3 to 6
times a year.
c. Under extreme temperature conditions
and extremely dirty atmospheres, lubrication should be at least once or twice a
month.

MOTOR LUBRICATION
In general, standard motors are furnished
with prelubricated, sealed-for-life ball bearings which require no lubrication for 7 to
10 years of normal service. Where motors
have been ordered with greasable bearings, these bearings are factory lubricated
and require no attention for one year under
normal conditions. If grease relief ttings
are provided, remove them when perform-
ing maintenance to allow grease to ow
out. Whenever possible, apply grease while
the motor is running. This practice should
not supersede any safety considerations.
DO NOT OVER GREASE, as most lubricants deteriorate motor windings, thereby
reducing motor life.
Hidden Danger
In addition to the normal dangers of rotating machinery, fans present an additional
hazard in their ability to suck in not only air,
but loose material as well. Solid objects can
pass through the fan and be discharged
by the impeller as potentially dangerous
projectiles. Therefore, screen intake to
ductwork, whenever possible, to prevent the
accidental entrance of solid objects. Never
open access doors to a duct system with the
fan running.
When starting the fan for the rst time, completely inspect the ductwork and inte-rior
of the fan (with power locked off), to make
certain there is no foreign material which
can be sucked into or blown through the
ductwork.
Guards
All fans have moving parts which require
guarding in the same way as other moving
machinery.
Where the fan is accessible to untrained personnel or the general public, use maximum
safety guards, even at the cost of some
performance loss. Unprotected fans located
less than 7’ above the oor also require
guarding as specied in the Occupational
Safety and Health Act (OSHA).
PennBarry recommends the use of guards
on all exposed nonducted fans, ceiling and
wall mounted.
Centrifugal fans may be connected directly
to ductwork which will prevent contact with
the internal moving parts, but when the inlet
or outlet is exposed, install a suitable guard.
