User Notice The total capacity of the indoor units which runs at the same time can not exceed 150% of that of the outdoor units; otherwise, the cooling (heating) effect of each indoor unit would be poor. Switch the main power on 8 hours before start the unit, helpful for a successful startup. It is a normal phenomenon that the indoor unit fan will still run for 20~70 seconds after the indoor unit receives the “stop” signal so as to make full use of after-heat for the next operation.

by johnson controls Maintenance Maintenance WARNING ！ ① . The unit can only be cleaned after the unit is turned off and the main power is cut off; otherwise it would cause an electric shock hazard. ② . Do not dampen the air conditioner, as it would cause a electric shock hazard and never rinse the unit with water in any event. CUATION ！ ① . Volatile liquid, like thinner, gasoline etc would damage the appearance of the air conditioning unit.
by johnson controls Troubleshooting Troubleshooting WARNING ！ ① . In the event of abnormal conditions (like, stinky smell), please shut off the main power supply immediately and then contact the YORK appointed service center; otherwise the continuous abnormal running would damage the air conditioning unit and also would cause ele ② .
