CODE READY™ TECHNOLOGY ACTIVATION
The Code Ready Technology option allows to change the blower output from the 600 CFM factory setting to a
maximum of 400 CFM or 300 CFM . Activating the CRT option will reduce the airflow, so that the powerpack insert
will perform within the allowable limit of Make-Up Air (MUA) codes (to meet some building code requirements) . Do not
change the blower CFM setting unless this change is required by code . This change will alter the performance of the
product .
iMPortant notes: 1. This change CANNOT be reverted.
2. CRT can only be set within the first 5 minutes of applying power to the unit.
3. A power outage will not deactivate the CRT.
4. Fan and lights must be OFF.
