blower door.
The APEX has two energy recovery wheels. Open
the exhaust blower access doors to access each

cassettes do not slide out due to their size and

before performing any type of service.**
ACCESSING ENERGY RECOVERY WHEEL
Energy Recovery Wheel Maintenance
Annual inspection of the energy recovery wheel is
recommended. Units ventilating smoking lounges
and other non-clean air spaces should have
energy recovery wheel inspections more often
based upon need. Inspections for smoke
ventilation applications are recommended
bimonthly to quarterly until a regular schedule
can be established.
