CONTROLS
On/Off Switch
Simple one touch controls – The green light above the POWER button will illuminate confirming power to the
unit.
Blower/Fan
The GS1-100 unit utilizes a variable speed blower with three speed settings. Press the up and down arrow
buttons to increase/decrease blower speed. A green light next to the specific speed (Low, Med, or High) will
indicate speed setting. In the case of a blower failure, all 3 blower speed lights will flash. To reset the blower’s
internal thermal protection, disconnect the unit momentarily from its power source and reconnect. If the lights
continue to flash contact Fumex LLC. for replacement information.
Filter monitoring
The GS1-100 unit utilizes a pressure differential switch to monitor the status of the Pre-filter. The system
monitors across all filters simultaneously and the Red “FILTER” light will illuminate when the Pre-filter needs to
be replaced. The recommended procedure is to replace the Pre-Filter and then press the “FILTER RESET” button.
If the light remains illuminated or turns off and comes back on then contact Fumex for assistance.
The GS1-100 unit contains a VOC sensor to detect odors/gases in the exhaust stream. When the gas/odor filter
becomes saturated and breakthrough of the VOC occurs the “GAS” warning light will illuminate.
