Fumex (Standard, Heat & Smoke & Restaurant Exhaust)
Centrifugal Roof & Wall: Direct & Belt Drive Exhausters

Description

Designed for severe service removing foul air from industrial and commercial buildings,
laboratory fume hoods. Housing and wheel constructed of aluminum; heat and smoke
removal utilizes a steel wheel. Motor compartment externally cooled and located out of
the discharge airstream. Power ventilators suitable for Restaurant Exhaust Appliances
(YZHW) are accordingly labeled. Power ventilators suitable for smoke removal are ac­cordingly labeled. These units require installation according to NFPA-96 standards, lo­cal codes and general practices. Up to Model 24B are available wall mounted (WFX).

DAMPERS: ROOF MOUNTING

When required, install dampers prior to
mounting the unit on the curb or frame.

Dampers are sized to t within the roof

opening. Secure using standard hardware.
If the damper is installed on the inside of the
curb, a piece of wood may be required as a
“spacer”. Do not twist or 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 applied on motor
terminals.

ANCHORING AND INSTALLING
THE VENTILATOR

Roof mounting may be in accordance with
the latest edition of NFPA-96 and local

codes. If not specied by codes), secure

unit to curb through pre-punched holes in
the ventilator base vertical ange (see Fig­ure 1 below).

In order to complete some installations, spe-

cically kitchen exhaust, you will require an

18” high curb as well as a weather resistant
junction box and hinge assembly.

Guy down large units installed in areas sub-

ject to high winds or unusual eld con-d it

ions. If the installer removes any ventilator
parts to facilitate installation or electrical
connection, 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.

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 during 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 likely 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

When the unit is installed on a sloped roof,
suitable footing and/or other safety devices
must be provided around the ventilator for
normal maintenance. Depending upon the
site conditions, the hinging of the ventilator
off the curb during maintenance should be
either parallel to the roof ridge or toward the
roof ridge, but NOT away from the ridge.

NFPA-96 recommends t h at da m p ers
sh o u ld not be installed when exhauster is
used for the removal of smoke and grease
laden vapors from commercial cooking
equipment. Consult state and local codes for
detailed requirements.

FLOATING HINGE INSTRUCTIONS

1. If any gasket is to be eld installed, this

should be completed before installing
the oating hinge. If a grease collec­tion box will be installed, it should be

installed after installing the oating

hinge, and not on either the hinge or
handle sides of the unit.

2. If this item is provided, hardware is
included. Review gure 2 for illustra­tions regarding this installation. De­tailed instructions should be provided
with the hinge kit, which are summa­rized below. The hinge kit instructions
take precedence over these instruc­tions.

3. Take back plate and position inside
the pedestal to allow for the pedestal

metal thickness, ush with both the

top and rear vertical surfaces. Use
this plate as a template to mark the

WALL MOUNTING

Fumex fans are available with round
bases to facilitate wall mounting through
size 24B (WFX), If installing these units,
ensure the wall mounting surface is leak-

SQ

free. To assure weather-tightness, coat the
entire rear side (that portion which mates

with the wall) of the mounting ange with

a suitable caulking compound or an ap­proved waterproof mastic sealer.

On masonry walls, attach the base ange

with lead cinch type anchors and a non­ferrous bolt. On sidings, use nonferrous
lag bolts. Washers are recommended to be
used under the bolt heads.

Operation & Maintenance Manual

Positioning and Running
Power Lines

ROOF MOUNTING

Power is normally brought from within
the building through proper conduit lines
and placed inside the curb. Feed power
through the ventilator to the (Disconnect
Switch or Junction Box) motor. Wiring can
be brought through the cooling tube from
the outside; this is the method to be used
for NFPA96, as well as smoke controll
systems installations if an external discon­nect junction box is not already provided.

WALL MOUNTING

Power is normally brought up from within
the building through proper conduit lines to
the wall opening, then fed to the (Discon­nect Switch or Junction Box) motor. Wiring
can be brought through the cooling tube
from the outside; this is the method to be
used for NFPA96 installations if an exter­nal disconnect junction box is not already
provided.

Start-Up and Operation

Carefully inspect the unit before startup.
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 the power source. Check
all set-screws and keys. Tighten when
necessary. Check the condition of belts
and the amount of tension prior to start-up.
DO NOT overtighten, as bearing dam-age
will occur.

Recommended belt tension should permit
deection of 1/64” per inch of span. Exer­cise extreme care when adjusting belts as
not to mis-align pulleys. Any misalignment
will cause a sharp reduction in belt life and
can produce excess belt noise. (see Fig­ure 4). On units equipped with two groove
pulleys, adjust all belts with equal tension.

Figure 4: Pulley Alignment & Tension

WRONG WRONG CORRECT

Not to exceed 1/64” per inch of span

Belts must be adjusted after approx. 40
hours of operation.

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.

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, chemicals, grease
or oil. Use only UL recognized electrical
parts, rated for proper voltage, load and
environment.

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

h. Check belt for proper belt tension

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 mot ors, t he t ermin al 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.

Do not operate models from line frequen­cies higher than 60Hz + or -5% with stan­dard motors.

The ventilator has been checked at the fac­tory prior to shipment for mechanical nois­es. If mechanical noises should develop:

a. Check rotating component for

adequate clearance and direction of
rotation. See page 6 for the wheel
alignment procedure. See top of plate
for wheel direction.

b. Check proper belt tension

and pulley alignment.

c. Check installation and anchoring.

d. Check fan bearings.

e. Check that cooling tube is in place

and well sealed.

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 Fumex Centrifugal Roof & Wall: Direct & Belt Drive Exhausters

f. Check motor and bearing tempera-

ture 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 con­dition 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 opera­tion, 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 recommen­dations. 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. Belt alignment.

c. Belt tension.

Maintenance

Do not attempt maintenance on the 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 be accidentally 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 centrifugal
wheel, inlet, motor housing and other
moving parts.

FAN SHAFT LUBRICATION

Fan shaft bearing pillow blocks are fur­nished in either the pre lubricated sealed­for-life type or the greasable type. The
prefabricated type requires no servicing
for 7 to 10 years of normal use. Follow the
lubricating schedule recommended by the
factory. This practice should not super­sede any safety considerations.

Use low pressure

grease guns only. High
pressure guns tend to blow out or unseat
bearing seals, leaving the bearing open to
collect grime, dust and foreign particles.

LUBRICATION SCHEDULE

Always follow the bearing manufacturer’s
recommended lubrication schedule. If
none is available use 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 atmosphere 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 condi-

tions and extremely dirty atmos­pheres, lubrication should be sched­uled at least once or twice a month.

d. Belt drive units maximum tempera-

ture should not exceed 160°F.
Direct driven models have tempera­ture range stamped on motor.

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.

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 locat-

ed less than 7’ above the oor also require
guarding as specied in the Occupational

Safety and Health Act (OSHA). PennBarry
strongly 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.

Replacement Parts

Replace parts with components which du­plicate original parts correctly. Incorrectly
sized shafts, belts, pulleys, etc.
can damage the fan.

Spare or replacement parts and prices are
available upon request. Please supply the
following information: Factory Order Num­ber, Customer’s Name and Order Number
and Date. If this information is not available,
furnish a complete description of the part re­quired. Names of parts are shown on page 7.
To order motors provide the HP, RPM, volt­age, phase, hertz and type of enclosure.
