blower door.
The APEX has two energy recovery wheels. Open

cassettes do not slide out due to their size and
weight.
**WARNING: Disconnect power to the unit
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.
