INTRODUCTION

Receiving and Handling

PennBarry fans are carefully inspected before leaving the factory. When the unit is received, inspect the carton/crate 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 carton/crates 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/crate 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/crate. Open carton/crate 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/ crate. Inspect the unit for any damage that may have occurred during transit and check
for loose, missing or damaged parts.

INSTALLATION

ROOF MOUNTING

The PennBarry FS is a fresh air supply fan. Accordingly, before installation, make sure that the unit is not located next to an exhaust
fan so that dirty or noxious air is not brought back inside the building. Mounting the unit on a roof necessitates prior installation of
the proper height and size roof curb. Curb must be installed securely and sealed carefully to the roof construction. Dampers, when
required, should be installed prior to mounting on the curb.

Dampers must be secured to the inside of the 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

Power is normally brought from within the building through proper conduit lines and placed inside one corner of the curb. It is
then fed through the clearance hole provided in the damper and, in turn, fed through the fan to the service switch, if furnished. The

number of wires, type of insulation and protection by metal rigid or exible conduit must be suitable for motor load on line voltage

service.

NOTE: Care should be taken to follow all local electrical safety and building codes. All electrical parts must be grounded, and grounding
conductor should be checked for continuity.

Some local codes prohibit the connection of in-line, aluminum fans in kitchen hood exhaust systems. According to present NFPA96
interpretation, ANY fan used in such duct work must be made of steel, with liquid-tight welds at all seams and connections. If local
codes are in accordance with NFPA96, do not use ANY FAN that is not completely welded closed for such duty. Refer to PennBarry’s
Fumex and Dynamo products for roof and wall mounted exhausters approved for use on kitchen hood exhaust systems.

ANCHORING AND SECURING THE FAN

Units should be seated on a properly sized curb. The gap between the base of the fan and the top of the curb should be sealed with a

neoprene 1” X 1/4” gasket. The gasket should be glued or attached with a pressure-sensitive adhesive. The fan must be rmly secured

to a metal curb with stainless steel or cadmium coated self-tapping screws, 18” on center. Units installed in areas subject to high

winds or unusual eld conditions may require additional fastening with guy wires. If the contractor removes the ventilator parts to

facilitate installation and electrical connections, all parts should be reassembled replacing all spacers, washers, nuts, bolts, fasteners
and components exactly as they were found prior to removal. All fasteners are to be drawn tight and secure.
