GENERAL SAFETY INFORMATION
Only qualied trained personnel should install or maintain equipment described in this document. Improper installation can result in
electric shock, possible injury due to high speed moving parts, or other potential hazards. Special circumstances such as high winds
or wet surfaces must be considered when installing the unit. Contact a PennBarry engineer if any questions or issues arise or if any
other information is needed before installing or maintaining the fan.
1. Follow all local, state and federal electrical and safety codes, as well as the National Electrical Code (NEC) and the National Fire
Protection Agency (NFPA) where applicable. Follow the Canadian Electrical Code (CEC) in Canada.
2. Make sure that the wheel spins freely without hitting or rubbing on any parts or objects.
3. The motor must be grounded; failure to ground a motor can result in a serious safety hazard.
4. The fan impeller should not be operated at RPM’s exceeding the rated RPM. If fan speed is higher than rated, the motor may
over amp, causing serious damage to the motor and other moving parts of the fan.
5. Power cord must be free of any kinks or pinches and must not come into contact with grease, oil or other liquids, ammable or
otherwise.
6. Verify that incoming power to the unit is of the correct voltage stated on the unit and/or motor nameplate.
7. Turn unit o before opening any access panels.
Receiving
PennBarry fans are carefully inspected and tested before leaving the factory. When the unit is received, inspect the packaging 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.
Unpacking
Upon reception, verify that all required parts and the correct quantity of each part have been received. If any items are missing,
report these to your local PennBarry representative. Due to variation in shipping carriers and availability, some items are shipped
separate from one another. Conrmation of shipment(s) must be limited to only items on the bill of lading.
Storage
Store in a dry, protected area being sure fan shaft, bearings and impeller are protected against dust and corrosion. If it is necessary
to store outdoors or within a building under construction, special care must be taken to prevent moisture, corrosion, dirt or
dust accumulation. Coat the shaft with grease or a rust preventative compound. Cover and seal bearings to prevent entrance of
contaminants. Impeller should be rotated at least once a month to circulate the grease in bearings. If stored outdoors over seven
(7) days, cover completely with a tarp or heavy waterproof paper. Electrical connections and leads must be protected from moisture.
Block impeller to prevent natural rotation. Do not allow material of any kind to be piled on top or inside of fan.
Always disconnect power before working on or near a fan. Lock and tag the service switch or breaker to prevent
accidental power up.
When servicing the fan, motor may be hot enough to cause pain or injury. Allow motor to cool before servicing.
Precaution should be taken in explosive atmospheres.

Inspection and Maintenance during Storage
Long-term storage is dened as storage for a period exceeding one month from the date the equipment was received. Fans and
motors should be stored in a dry, low humidity area indoors. Equipment which is to be installed, but not operated for several months,
should rst be blocked to take the weight o of the vibration isolators (if provided) and then given the same protection, periodic
inspection and maintenance as a unit in storage. To prevent puddle corrosion of fan bearings that undergo long-term storage, the
following preventive maintenance must be performed:
1. Fan bearings must be re-lubricated every month until the fans are put into service. A clear 1/16” bead of grease must appear
on each side of the bearings. Fan wheels are to be rotated manually while the bearings are re-lubricated. Refer to the specic
bearing lubrication instructions located on the fan housing for the type of lubricant to use.
2. Motor bearings should be lubricated as recommended by the motor manufacturer.
Removing from Storage
Fans should be hoisted with slings placed around the fan housing. When a single hoist is used, a “spreader” will keep the sling from
slipping on the housing. Fans must be protected and maintained from the time of storage to the time of assembly and installation.
Ensure that the fan is in working order before assembly and installation. Be sure that no damage has occurred between storage and
time of assembly.
1. Ensure that all fasteners, ttings, screws, etc. are tightened to recommended specications.
2. Make sure that no parts or objects are rubbing on the fan wheel as it is turned.

GENERAL INFORMATION
Unit identication tags
Each unit has a permanently axed nameplate with various identications including, but not limited to, the unit model and serial
numbers, motor ratings and voltages.
The gure below is an example of a PennBarry unit nameplate. It includes all of the specications of the unit, as referenced above.
When contacting your PennBarry representative, please have the information on the nameplate readily available, as this will help to
streamline your help request.
Fan components may arrive in pieces or assemblies depending on the fan conguration. Components of the fan will have matching
nameplates, and these components should not be mixed with other PennBarry fans. If mismatched components are installed in the
same fan, fan performance may be reduced.
Pre-Installation information
Ensure that the mounting surface where the unit is to be installed is completely level and free of debris. The mounting surface must
also be able to bear the entire weight of the fan.
Electrical service switches
An electrical service switch must be installed either on the unit or in visual proximity to the unit, so that the unit can be easily turned
o for maintenance or trouble shooting. These must be locked out when the unit is being maintained or serviced.
Moving parts
Any moving parts on the unit must have covers or guards to protect any servicers or personnel. These guards are to be installed in
accordance with local codes. The fan wheel must be secured before performing any maintenance on the unit; damage to the wheel
is possible if this precaution is not taken.
Guards (Motor/Weather cover)
All parts of the unit, including guards and covers, must be installed before attempting to start the unit. Do not operate the unit with
any missing pieces, particularly any guards or covers; this includes any hardware such as nuts and bolts, which hold these covers in
place.
Air pressure and suction
Fans moving at any speed create suction with varying degrees of strength. Special consideration needs to be taken when working
around these units. Do not leave any loose articles of clothing or materials in or around air intake or fan inlet.

LIFTING INFORMATION
DUCT INSTALLATION
Fans should be hoisted with slings placed around the fan housing. When a single hoist is used, a “spreader” will keep the sling from
slipping on the housing. If it is necessary to use hooks placed in lifting holes of fan, BE CAREFUL NOT TO DISTORT OR BEND THE
HOUSING. Lifting lugs or holes should be used only to stabilize the unit while using a sling to support the weight. Chain or wire
slings should be well-padded where they contact the fan, especially where special coatings and paints are involved. Rubber, phenolic
enamels, etc. require special care as they may easily be damaged by contact in lifting. Even a small chip will destroy the corrosion
prevention seal of the coating and allow corrosion to start. Always repair scratched surfaces with touch up of like coating prior to
installation.
Slip-t duct connections are available at both the inlet and outlet connections. Fan may be installed directly onto the ducting by
slipping over the connecting duct. Some applications may require the use of anged connections or exible duct connections, both
of which are accessories oered by PennBarry. For vertical applications, a anged connection type is preferable.
