Page 46: Iceberg Cooler Service
16.0 Iceberg Cooler Service Pre Season Maintenance The service to a Iceberg requires access to the home to check the performance of the unit through the duct system and the function of the wall control. Service work performed without access cannot be responsible for the system operation, only the Coolers function. - Page 47 Check the air distribution is correctly balanced. Check there is adequate exhaust opening available for correct operation. Check the Iceberg wall control is located in a suitable position for correct operation. Check the unit operates in both Manual and Auto modes.
