MAINTENANCE

CAUTION
MAKE SURE UNIT IS UNPLUGGED BEFORE ATTEMPTING ANY MAINTENANCE WORK
The following components should also be inspected regularly and well maintained.
PRACTICAL
TIPS
• To prevent electrical shock,
check that the unit is
unplugged before doing any
repairs or maintenance.
• A yearly inspection
recommended to ensure the
efficiency and trouble-free
use of your system. Run
through the system
and verify the different
operating modes.
The motor - The motors are
factory balanced and lubri-
cated for life. They require
no maintenance.
The unit - The inside of the
unit should be vacuumed
yearly. Be careful not to
damage any of the mechan-
ical components and electri-
cal connections.
(CONT'D)
the duct and place the flow
measuring station between each
station. Make sure that the flow
measuring station's air direction
arrow points in the direction of the
airflow. Secure the flow measuring
station with duct tape.
sure that the magnehelic gauge is
level and at 0. Refer to the flow
measuring station's chart to
determine your unit's airflow
velocity.
FILTERS
The filters (4) need to be
checked and cleaned every
three months or when they
appear dirty. Wash in warm
sudsy water (mild detergent)
is
or use a soft brush vacuum.
The filters should be replaced
when they can no longer be
cleaned properly.
ENERGY RECOVERY CORE
Clean the Enthalpic core annually or as needed with a vacuum cleaner. Use a soft brush attachment.
Make sure the filters on the unit are cleaned. Failure to clean or use filters may damage the Enthalpic
core resulting in a void WARRANTY.
Note: The use of the Enthalpic core in adverse environment conditions such as dust, oil mist, exces-
sive kitchen grease, corrosive fumes, organic solvents, paint or any other harmful chemicals can
damage the Enthalpic core and in such void the warranty.
The drain pan and drain line - Units with drain lines should have their line and connec-
tion checked regularly.
Outside hoods - The outside hoods need to be checked every season to make sure there
are no leaves or insects blocking the airflow. Check regularly that there are no pollutants
near the intake hood. Make sure they are clear of any snow accumulation during the win-
ter months.
3 Adjust the damper until you reach
the desired velocity.

• To avoid airflow
turbulence and incorrect
readings, the airflow
velocity should be
measured on steel
ducting a minimum of
18" (457 mm) from the
unit or elbow and before
any transition.
