The ERM models contain a total energy recovery
wheel. The wheels are inspected for proper
mechanical operation at the factory. However, during
shipping and handling, shifting can occur that may
affect wheel operation. The wheel is accessible
through the cassette access panel.
Turn the energy recovery wheel by hand to verify
free operation. The wheel should rotate smoothly at
approximately 50-60 rpm and should not wobble. If
the wheel does not rotate when power is applied, it
may be necessary to adjust excessively tight diameter
air seals.
