Your wall controller (ACCGSC1 or 40425) tells you when to perform this maintenance when the Filter Maintenance light is flashing.
Otherwise, maintenance should be performed every 6 months to ensure your unit proper operation for years to come. Follow these steps:
1. Turn switch knob to OFF to unlock the door.
2. Unlatch the door and open it. If required, the door can be removed. To do so, remove the
stopper (A) located on the right side of the door hinge. Then, hold the door and hit with your
palm its left side. Slide the door to the right to disengage it from the unit. Clean the inner side
of the door with a clean damp cloth, then wipe with a dry one.
3. Slide out the air diffuser (model GSVH1K), the heat recovery module (model GSHH3K only), the energy recovery module (model
GSEH3K only) and the filter cartridge from the unit.
