PennBarry Domex Operation & Maintenance Manual

Domex, Centrifugal Roof, Direct & Belt Drive Exhausters
Receiving and Handling
PennBarry fans are carefully inspected be-
fore leaving the factory. When the unit is
received, inspect the carton for any signs
of tampering. Inspect the unit for any dam-
age that may have occurred dur-ing transit
and check for loose, missing or damaged
parts. Mishandled units can void the war-
ranty provisions. If units are damaged in
transit, it is the responsibility of the receiver
to make all claims against the carrier. Pen-
nBarry is not responsible for damages in-
curred during shipment.
Avoid severe jarring and/or dropping.
Handle units with care to prevent damage
to components or finishes. If the unit is
scratched due to mishandling, the protec-
tive coating may be damaged. Incorrect
lifting may damage the fan and void the
warranty.

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. Ventila-
tors are furnished with self-aligning, pre-lubricated, ball bearing pillow blocks, spark
proof aluminum wheels, and aluminum backdraft damper.
Storage
Long-term storage requires special atten-
tion. Store units on a level, solid surface,
preferably indoors. If outside storage is
necessary, protect the units against mois-
ture 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 manufactur-
er'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 flaps. Remove any
cardboard and wooden filler 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.

INSTALLING MOTORS
In some instances, large frame motors
may be shipped loose and require field
mounting. If so, carefully review motor
mounting installation procedures per Fig-
ure 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 opera-
tion. If dampers are motor operated type,
ascertain that proper voltage is impressed
on motor terminals.
