STORAGE
When a unit is not going to be in service for an extended amount of time, certain procedures should be
followed to keep the fans in proper operating condition.
•Rotatefanwheelmonthlyandpurgegreasefrombearingsonceeverythreemonths
•Coverunitwithtarptoprotectfromdirtandmoisture(Note:donotuseablacktarpasthiswillpromote
condensation)
•Energizefanmotoronceeverythreemonths
•Storebeltsflattokeepthemfromwarpingandstretching
•Storeunitinlocationwhichdoesnothavevibration
•Afterstorageperiod,purgegreasefromfanbearingsbeforeputtingfanintoservice
If storage of unit is in a humid, dusty or corrosive atmosphere, rotate the fan and purge the bearings once a
month. Improper storage which results in damage to the unit or components will void the warranty.
BASIC OPERATION
The HRE brings in fresh, outdoor air and
removes stale, exhaust air. For summer
operation, the exhaust air flows through an
evaporative cooler (indirect) to lower the
air temperature. A sensible recovery wheel
transfers energy from the exhaust air to
the outdoor air at an efficiency of 70-80%
to reduce the temperature of the outdoor
air. The outdoor air can then flow thru an
optional evaporative cooler (direct) to further
reduce the temperature of the outdoor air.
The sensible wheel also recovers heat from
the exhaust in the winter to precondition the
outdoor air. Optional heaters are available
after the wheel for final tempering.
