Operation & Maintenance Manual
Please read and save these instructions. Read carefully before attempting to assemble, install, operate or maintain the product de-
scribed. Protect yourself and others by observing all safety information. Failure to comply with instructions could result in personal injury
and/or property damage! Retain instructions for future reference.
Type 2 Type 3 Type 1
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 nishes. 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.
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 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
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 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.
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.

Overview

The Domex, Centrifugal Roof, Direct & Belt Drive Exhausters are roof-mounted ventilators designed to meet air delivery requirements where steady exhaust is needed under moderately static pressure. These exhausters are constructed with built-in backdraft dampers and are furnished with self-aligning, pre-lubricated, ball bearing pillow blocks, spark-proof aluminum wheels, and aluminum backdraft dampers.

Function Description:

These exhausters are designed to provide steady exhaust for various applications. The direct drive models, such as DX06R, DX08S/R, 10S/R, 11S/R, 11Q, 13V/S/R, 13Q, 16V/S/R, Q1 & Q2, are suitable for general exhaust needs. The belt drive models, including DX06B-36B, KB, JB & MB, offer flexibility in performance through belt adjustments. Explosion-proof motor versions are available for hazardous environments, ensuring safe operation by preventing sparks that could ignite flammable gases or dust.

Important Technical Specifications:

  • Construction: Roof-mounted, built-in backdraft dampers, self-aligning, pre-lubricated, ball bearing pillow blocks, spark-proof aluminum wheels, and aluminum backdraft dampers.

Usage Features:

  • Installation: Detailed instructions are provided for installing on various roof types (concrete slab, steel framed, wood framed). Proper anchoring and sealing are crucial for optimal performance and weather resistance.
  • Receiving and Handling: Upon receiving, inspect the carton for any damage. If damage is found, file a claim with the carrier. Do not discard damaged parts until the claim is resolved.
  • Start-Up and Operation: Before start-up, check all motor bearings, ensure proper belt tension (for belt drive models), and verify that all fasteners are securely tightened. Rotate the centrifugal wheel by hand to ensure free movement.
  • Belt Drive Adjustment (for belt drive models): Adjusting belt tension is critical. Too much tension can cause premature bearing failure, while too little can lead to slippage and reduced performance. Use a belt tension gauge for accurate adjustment.
  • Wiring: All wiring must comply with National Electrical Code (NEC) and local codes. Explosion-proof models require wiring practices and regulations appropriate for hazardous locations, including the use of sealed conduit and proper connections.
  • Backdraft Dampers: These are built-in to prevent reverse airflow when the fan is not operating.
  • Wheel Alignment: Procedures are provided for "Front to Back" and "Side to Side" adjustments, as well as "Vertical" adjustment, to ensure smooth and efficient operation.

Maintenance Features:

  • Lubrication:
    • Ball Bearings: Pre-lubricated, but regular lubrication is required. For normal conditions, lubricate every 1-2 years. For dirty or humid conditions, lubricate every 3-6 months. For extreme conditions, lubricate monthly.
    • Pillow Blocks: Pre-lubricated, but regular lubrication is necessary. For normal conditions, lubricate every 1-2 years. For dirty or humid conditions, lubricate every 3-6 months. For extreme conditions, lubricate monthly.
    • Fan Shaft Bearings: Pre-lubricated, but regular lubrication is necessary. For normal conditions, lubricate every 1-2 years. For dirty or humid conditions, lubricate every 3-6 months. For extreme conditions, lubricate monthly.
  • General Maintenance:
    • Regular Checks: Periodically check for excessive vibration, noise, loose fasteners, and belt tension (for belt drive models).
    • Cleaning: Keep the fan wheel and housing clean to maintain efficiency.
    • Motor Maintenance: Do not attempt maintenance on the motor until the electrical supply has been completely disconnected. If a disconnect switch has not been provided, remove the fuse from the circuit or lock out the fuse panel so they cannot accidentally be replaced.
    • Troubleshooting: A comprehensive troubleshooting checklist is provided to diagnose and correct common issues like excessive noise, fan inoperative, insufficient airflow, water leaking, and motor overheating.
  • Warranty: A one-year limited warranty covers defects in material and workmanship. It includes repair or replacement of defective products. Exclusions apply for improper design or operation, improper installation, accident, abuse, or misuse.
