The karolina cooling capacity decreases as the outdoor temperature increases. This causes the karolina to work harder and longer to hold the selected room temperature. Indoor Coil Freeze Protection: Frost may form on the indoor coil during cooling operations when the outdoor temperature below 50°F (10°C). Prolong operation may cause ice to form on the indoor coil and block airflow. If the karolina indoor unit microcomputer detects ice on the indoor coil it will stop the compressor to defrost the coil and protect the unit. HEATING OPERATION How it works: In heating mode, your karolina outdoor unit will absorb heat from the outdoor ambient, then the karolina indoor unit will discharge the heat to the room. The karolina heating capacity decreases as the outdoor temperature decreases. During extreme cold outdoor temperatures, you may need an additional heating source to supplement the karolina heating output. Defrost Function: In heating mode, frost may form on the outdoor coil during humid and low outdoor temperature conditions. Prolong operation may cause ice to form on the outdoor coil and block airflow. This will reduce the karolina’s heating capacity. If the karolina microcomputer detects ice on the outdoor coil, it will switch automatically to defrost mode to melt the ice and clear the coil. During defrost mode, heating will be discontinued and the karolina indoor unit will flash the Defrost indicator. The compressor will continue to run while indoor and outdoor fans will stop. It is normal to see steam or vapor coming from the outdoor unit during defrost mode. Defrost mode will terminate 12 minutes after initiation of defrost cycle or when the outdoor coil temperature is 50°F (10°C) or greater. 26 ENERGY SAVING TIPS 1. Relaxing room temperature at night is OK: During the nighttime hours you don’t require the same level of conscious cooling or heating. Try using Sleep Mode to gradually relax room temperature and allow the unit to run less and save energy. 2. Curtains and shades: In the summer, you need to block the effects of the sun. Close window curtains and shades on the south and west side of your home to help block solar heat. In winter, the sun is your friend. Open curtains and shades to allow solar heat into your room. 3. Close doors: If you don’t need to heat and cool your whole home, confine the heating and cooling to one room by closing doors. Limit the space you’re heating and cooling to specified capability of the unit. 4. Service the unit: Some basic maintenance might be all you need. The outdoor unit will greatly benefit from a good hosing out, especially in treed areas where seeds and other debris can stick to coil fins and make the unit work up to 15% harder! 5. Rearrange the room: Furniture that obstructs airflow means you could be heating and cooling the back of a chair or the front of a sofa instead of the actual living space. Use the Swing Louvers to help direct the air in the right direction for the room; remove or rearrange obstacles blocking airflow. 6. Lighting: Turning lights off can help reduce your heat. Each light bulb is a tiny heater. Your air conditioner must waste energy overcoming the heat from your lights to reach and hold your desired room temperature. 7. Is anyone home? If possible, while you’re away turn your unit to Auto mode and make sure windows and drapes are closed. Although the room temperature will be uncomfortable for a few minutes when you come home, the unit will have the room back to your desired temperature in no time. 8. Don’t forget the fan: The fan is much like a car. The faster it runs, the more energy is uses. Sometimes we need the car to go fast, but slow is good enough most of the time. Try saving money by using the comfortable quiet low fan speed as much as possible. 27 www.cooperandhunter.us LIMITED WARRANTY STATEMENT Ductless Heat Pump Split System This warranty should be registered on our web-site www.cooperandhunter.us The warranty is only valid when installed by a Licensed HVAC Technician FOR WARRANTY SERVICE OR REPAIR: Contact your installing contractor.
