MAXXAIR MAXXFAN Dome 3810 wiring diagram

This is the non-LED MAXXFAN Dome 3810 roof or wall exhaust fan. The 3812 lighted version has additional wiring, so its light feed must not be inferred from the 3810 drawing. The opening and supply requirements, page 1, call for a 6¼-inch opening and a suitable roof or wall thickness of 1–6 inches.

Follow the non-LED diagram on page 5: connect the marked positive 12 V DC lead and negative 12 V DC lead with the supplied connectors. The catalog uses those labels rather than assuming a wire colour. Keep the connections protected from abrasion and water, and verify polarity before restoring power.

MAXXAIR requires a 12 V supply capable of at least 2 A. That is a minimum service capability, not a stated operating current. The manual also identifies a 5 A GMA fast-acting internal fuse on page 7. Neither value establishes the continuous rating of the connector or the correct source-branch fuse for every cable route. Running draw and extension sizing remain unspecified here, so no invented daily energy estimate or complete generic supply circuit is shown.

Use the supplied mounting sequence and a sealant compatible with the mounting surface. Open the lid before running the fan; the lid is not a motorised damper. Keep the screen fitted and keep hands away from the blade. This is a general ventilation fan, not equipment for exhausting combustible vapours.

Confirm that the lid opens freely, the fan starts on its own switch, and the flange remains sealed after a water check. If the appliance fuse has opened, isolate power and investigate before replacing it with the same type. Clean the accessible surfaces and screen using the manual's mild-cleaner method rather than solvents that can damage the plastic.
