Airflow is controlled within +/- 5% up to Max ESP shown with wet coil and standard 1” fiberglass filter.

Units with ClimaDry II are factory set to opperate in stage 2 airflow.

HZ Series with ClimaDry II

All HZ units have an ECM fan motor. The small amount

of additional pressure drop of the ClimaDry II coil causes

the ECM motor to slightly increase RPM to overcome the

added pressure drop and maintain selected CFM up to the

maximum ESP.

Unit minimum operating temperature when in the

dehumidification or cooling mode is 65°F DB. Operation

below this minimum may result in nuisance faults.
