CLEANING AND MAINTENANCE

To avoid the possibility of electric shock, always turn off power to the system before performing any cleaning or maintenance to the system. Turn off the outdoor disconnect switch located near outdoor unit. Be sure to disconnect indoor unit if on a separate switch.

Operating the system with dirty air filters may damage the indoor unit and could cause reduced cooling performance. Intermittent system operation, frost build-up on indoor coil and blown fuses may also result from system operation with dirty air filters.

Air Filters — Remove and clean the air filters when the Filter lamp on the unit display panel is lit. See Fig. 14 and 15.

NOTE: If air filters show signs of excessive wear or are torn, they must be replaced. Contact your local dealer for replace- ment filters.

1.Open front panel on unit.

2.Pull filters down to remove.

3.Vacuum filters.

4.Clean with warm water.

5.Shake filter to remove excess water and dry thoroughly.

6.Replace filter by sliding filter behind front grille until fil- ter snaps in place. See Fig. 15.

7.Slide Operation Switch on unit to OFF position to cancel Filter status lamp.

8.Slide Operation Switch on unit to REMOTE position to resume remote control operation.

Indoor Unit Front Panel — To clean the front panel on the indoor unit, wipe the outside with a soft, dry cloth. If neces- sary, a mild liquid detergent can be applied and wiped off with a dry cloth.

When cleaning the front panel, do not use water hotter than 105 F and do not pour water onto the fan coil.

Do not use abrasive or petroleum based cleaners as they may damage the front panel.

Indoor Unit Coil — To clean the indoor unit coil, remove the front panel and vacuum the coil fins. Avoid bending or damaging the fins.
