Routine Maintenance

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.

ACCESSING ENERGY RECOVERY WHEEL

The APEX has two energy recovery wheels. Open the exhaust blower access doors to access each wheel (FIGURE 26). The energy recovery wheel cassettes do not slide out due to their size and weight.

**WARNING: Disconnect power to the unit before performing any type of service.**
