Consider using the timer setting options.▪ Adjust the air flow direction to avoid cool air from gathering on thefloor or warm air against the ceiling. (Up during cooling or dryoperation to the ceiling and down during heating operation.)▪ Avoid direct air flow to room inhabitants.▪ Operate the system within the recommended temperature range(26~28°C for cooling and 20~24°C for heating) to save energy.7 Maintenance and service7.1 Overview: Maintenance andserviceThe installer has to perform a yearly maintenance.
