MAINTENANCE
The benefits of regular inspections and routine maintenance are well documented; regular service intervals keep the system operating
at peak efficiencies, extend operational life and ensure safe product operation.
BELTS
Improper belt tensioning is the most common cause of early belt failures. As such, it is imperative to tension a belt down to the
correct tension, which is the lowest tension at which the belt does not slip at peak running speed.
As a general rule, the belt should not deflect any more than 1/64 inch for every inch of belt span.
It is advised to check the belt tension at least twice within 24 hours of installation and regularly with scheduled maintenance
thereafter. Adjust belt tension by loosening the bolts on the motor plate to relieve the tension. Tighten belt tension by tightening
down the bolts on the motor plate.
Drive pulleys must be properly aligned, or belt slippage can occur. If pulleys are not aligned, the unit will not run efficiently, and noise
or premature failure can occur.
FASTENERS AND SET SCREWS
All hardware, screws and fasteners should have torque checked at every scheduled maintenance.
MOTORS
Most fractional horsepower motors provided with the unit do not require greasing or lubrication after they are installed. If motors
have grease fittings, then they should be re-lubricated according to motor manufacturer specifications.
REMOVAL OF DUST AND DIRT
The impeller and interior surfaces of the unit should be inspected and cleaned, if necessary, on a regular basis in accordance with
the maintenance schedule. Dirt and dust accumulation can throw the wheel off balance and cause other early failures in the unit. Do
not get water in bearings or motors when attempting to clean the unit.
FAN SHAFT BEARINGS
Bearings selected for Pennbarry fans are specially paired with the unit to achieve the maximum attainable efficiency and performance
of the fan. As such, they are one of the most crucial parts of the fan and must be maintained and mounted accordingly.
Notes: In this section, routine service internals are recommended.
Scheduled maintenance must be performed on the unit after it is in operation to ensure that it runs efficiently and reliably.
Ensure that all incoming power to the unit is switched off before attempting to service the unit. If this measure is not
taken, serious injury can occur to the servicer.
