Configuration

After installing the outdoor unit ALWAYS deactivate the high external static pressure function. This in order to avoid increased fan velocity and associated increase in outdoor unit sound emission.

INFORMATION
For more information on the field settings, see the installer reference guide or the service manual of the outdoor unit.

Maintenance

• The low sound enclosure is free of maintenance under normal conditions.
• Clean the outside with water and a neutral cleaning agent at least twice a year to keep the housing in optimal condition.
• To avoid the short circuit of the airflow, ALWAYS keep the slats openings free from debris and remove dirt such as leaves and snow.
