Fan Replacement Instructions

12v and 120v fans in Envirolet® Systems are covered under a 4-year replacement warranty. If you do need to replace a fan, please follow these instructions carefully. Call Sancor™ Technical Support if you require assisstance.

1. Safety: Unplug (120v Electric models) or disconnect (12v Battery models) the power supply cord.

2. Cut the silicone to break seal around the Top Panel (Self-Contained models only) on your Envirolet® Composting Toilet System. Envirolet® Remote Systems have a fitted rubber gasket under the Top Panel.

3. Carefully remove the screws from the Top Panel (all models).

4. Disconnect the Wiring Harness plug that connects the Top Panel to the Envirolet® Works-in-a-Drawer™ electrical box (WID Box) by pulling the male and female plug connections of the Wiring Harness apart.

5. Lift and remove the WID Box out of the unit.

6. Remove the screws (4) that attach the Fans from the bottom of the WID box. Only remove the screws from the fan you are replacing. The Blower Fan will be under the attached Blower Pipe. Be sure to reattach Blower Pipe before putting the WID Box back into the System.

7. Pull fan out and carefully disconnect the wiring. Do not cut any wires.

Important Note Please be sure to check the air flow direction of the replacement fan before installing it to ensure it is installed correctly. The air flow of the Fan is indicated on the side of the Fan and is also indicated by the label (the air flows up towards the label). Envirolet® Systems have 2 Fans. The Vent Fan blows air out of the Envirolet® System through the connected vent pipe. The Blower Fan blows air down into the bottom of the System. When looking at the WID box, with the open Heater “grill” on the right hand side, your Vent Fan is located on the left hand side. The Blower Fan is located on the right hand side (towards the middle, near the Heater in 110v Electric models).

8. Connect the replacement Fan to the wiring and secure with new screws provided. Do not over tighten screws.

9. Put the WID box into the unit and secure the top panel with screws and re-silicone to ensure a proper seal.
