ordered). Filters should be checked and cleaned on
a regular basis for best efficiency. The frequency of
cleaning depends upon the cleanliness of the incoming
air. These filters should be cleaned prior to start-up.
Clean filters by rinsing with a mild detergent in warm
water.
Internal Filter Maintenance
The units will typically be provided with 2-inch, pleated
filters in the outdoor air and exhaust airstreams. These
filters should be checked per a routine maintenance
schedule and replaced as necessary to ensure proper
airflow through the unit. See table for pleated filter size
and quantity for each unit. Replacement filters shall be
of same performance and quality as factory installed
filters. Filter type must be pleated design with integral
metal grid. Two acceptable filter replacements are
Aerostar Series 400 or Farr 30/30
Outdoor Air Filters: Access to the outdoor air filters is
through the door labeled as "Filter Access" on the sides

WARNING
Do not wash, soak in water, or use detergents and/
or cleaners on the fiber membrane core. This will
result in a damaged core and will not be covered by
the warranty.
WARNING
Energy core shall not be subjected to temperatures
greater than 140ºF. This will result in a damaged core
and will not be covered by warranty

Frequency of cleaning - A regular cleaning cycle
must be established for the energy recovery core in
order to maintain optimum sensible and latent energy
transfer. In reasonably clean environments such as
schools, offices or retail stores, the energy recovery core
should be inspected annually and cleaned as needed.
Failure to follow a regular cleaning cycle for the energy
recovery core can result in significant energy transfer
performance losses.
Accessing the energy recovery core - Disconnect
the power to the unit. Remove access panel.
Removing the energy recovery core - Once the
energy core access doors are removed, the core can be
pulled from the housing. To replace the core, reverse the
procedure.
Recommended cleaning
procedure - Once the core is
removed, gently vacuum the
surfaces of the core to remove
the dirt and debris that has
accumulated.
