Disconnect power to both the indoor and outdoor units. N OTE: There may be more than one electrical disconnect switch. Electric shock can cause personal injury or death. Z ! CAUTION - Although special care has been taken to minimize sharp edges in the construction of your unit, be extremely careful when handling parts or reaching into the unit. Filters When the heat pump circulates and filters the air in your house, dust and dirt particles build up on the filter. Excessive accumulation can block the airflow, forcing the unit to work harder to maintain desired temperatures. And the harder your unit works, the more energy it uses. Filters should be checked at least once a month and cleaned or replaced when needed. During seasons when the unit runs more often, clean or replace your filter twice a month. When replacing your filter, always use the same size and type that was originally supplied. Filters are available from your dealer or the local hardware store. Where disposable filters are used, they must be replaced every month with the same size as originally supplied. Before removing the filter, see the operating instruction manual furnished with the indoor unit. Ask your dealer where the filter is located in your system and how to service it. Make sure to replace it with the arrows pointing in the direction of the airflow. ! CAUTION - Condensate drains (see instruction with the indoor unit) should be checked and cleaned periodically to assure condensate can drain freely from coil to drain. If condensate cannot drain freely, water damage could occur . ! WARNING - Improper installation, adjustment, alteration, service, a maintenance, or use can cause explosion, fire, electrical shock, or other conditions which may cause personal injury or property damage. Consult a qualified installer or service agency for information or assistance. The qualified installer or agency must use factory-authorized kits or accessories when modifying this product. 4
