SECTION FOUR – Normal Operation and Maintenance
SECTION FOUR – Normal Operation &
Periodic Maintenance
General
Each unit on a job will have its own unique operating
environment and conditions which may dictate a
maintenance schedule for that unit that is different
from other equipment on the job. A formal schedule of
regular maintenance and an individual unit log should be
established and maintained. This will help to achieve the
maximum performance and service life of each unit on
the job.
Information regarding safety precautions contained in
the preface at the beginning of this manual should be
followed during any service and maintenance operations.
For more detailed information concerning service operations
consult your Sales Representative or the factory.
Motor/Blower Assembly
The type of fan operation is determined by the control
components and their method of wiring. This may vary
from unit to unit. Refer to the wiring diagram that is
attached to each unit for that unit’s individual operating
characteristics.
All motors have permanently lubricated bearings. No field
lubrication is required.
Should the assembly require more extensive service, the
motor/blower assembly may be removed from the unit
to facilitate such operations as motor or blower wheel/
housing replacement, etc.
Dirt and dust should not be allowed to accumulate on the
blower wheel or housing. This can result in an unbalanced
blower wheel condition which can damage a blower
wheel or motor. The wheel and housing may be cleaned
periodically using a vacuum cleaner and a brush taking
care not to dislodge the factory balancing weights on the
blower wheel blades.
Bipolar Ionizer Brush Cleaning
The bipolar ionizer is designed to not require replacements
parts.
The brushes on the device may become dirty over time
and will require cleaning to maintain the effectiveness
of ion output. Cleaning of bipolar ionizer brushes and
inspection of device should be performed at time of
each filter change or sooner, based on the location, filter
effectiveness and general environment.
1. To clean the brushes, turn off power to the unit.
NOTE: When power is OFF, the green LED
indicator on the device will not be illuminated.
2. Using a small nylon brush, gently wipe off the two
brushes. See Figure 22 for brush location.
3. After cleaning, restore power.
It is strongly recommended the bipolar ionizer be paired
with a Pleated MERV 8 filter for most effective indoor air
quality results.
