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.
