9. MAINTENANCE ! WARNING Risk of electrical shocks. Before performing any maintenance or servicing, always disconnect the unit from its power source. 0 9.1 SEMI-ANNUAL MAINTENANCE (ESSENTIAL) Your wall controller (ACCGSC1 or ACCGSC3) 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.
9. MAINTENANCE (CONT’D) 6.2 For HEPA Filtration, Fresh Air and Heat Recovery model GSHH3K only 1 1 Slide out the two core filters (item 1) from the heat recovery core and wash them under hot water with mild soap. Remove the dust on the heat recovery core (item 2) using a vacuum cleaner with a soft brush attachment. Rinse the core filters thoroughly and let dry before reinstalling them on the heat recovery core. Reinstall the heat recovery core in the unit.
9. MAINTENANCE (CONT’D) 9.2 ANNUAL MAINTENANCE (ESSENTIAL) Your unit is equipped with a wall controller (ACCGSC1 or ACCGSC3), which tells when to perform maintenance when the Filter Maintenance light stays ON. Otherwise, this maintenance must be performed once a year to ensure your unit proper operation for years to come. Proceed as the Semi-annual Maintenance (Section 9.1), but instead of replacing the prefilter (point 4), discard the complete HEPA Filter cartridge (including prefilter).
10. TROUBLESHOOTING PROBLEMS SOLUTIONS 1.Unit does not start at Low or High position. 2. Unit does not run at Low speed, but runs at High. 3. Unit is not operating as per the selected mode. 4. Wall control indicators do not work properly or not at all. 5. On ACCGSC3 wall control only, 1 or 2 light indicators are flashing every second. • Check breaker or fuse in main distribution panel or GFI outlet. • Check there is 120V at the electrical outlet.
