Humidifier auxiliary drain pan

A method for providing liquid overflow protection for a humidifier system, comprising:

• positioning an auxiliary drain pan vertically below a humidifier, the auxiliary drain pan having a base, a continuous wall around a periphery of the auxiliary drain pan extending upwardly from the base to form a container having an open end, a first opening formed in the base and a second opening formed in the auxiliary drain pan in fluid communication with the first opening;
• forming a fluid tight connection between the first opening and a first drainage conduit;
• forming a fluid tight connection between the second opening and a second drainage conduit;
• and
• forming an anti-backflow connection between the first opening and a conduit from the humidifier for directing liquid from the humidifier through the first opening and into the first drainage conduit, the anti-backflow connection preventing a reverse flow of liquid from the first drain conduit from reaching the humidifier through the humidifier conduit, the reverse flow of liquid from the first drainage conduit and through the first opening being received by the second opening and discharged from the auxiliary drain pan via the second drainage conduit.

A humidifier system for providing climate control to a space, comprising:

• a humidifier;
• an auxiliary drain pan positioned vertically below the humidifier, the auxiliary drain pan comprising:
• a base;
• a continuous wall around a periphery of the auxiliary drain pan extending upwardly from the base to form a container having an open end;
• a first opening formed in the base, the first opening having a first drainage connector extending from the base opposite the wall for connecting with a first drainage conduit;
• the first opening adapted to receive a backflow preventer for forming an anti-backflow connection with a humidifier conduit extending from the humidifier for directing liquid from the humidifier through the first opening and the first drainage connector, the anti-backflow connection preventing a reverse flow of liquid from the first drain conduit into the humidifier via the humidifier conduit;
• a second opening formed in the auxiliary drain pan in fluid communication with the first opening to receive the reverse flow of liquid from the first drain conduit through the first opening, the second opening having a secondary drainage connector extending from at least one of the base opposite the wall, and the wall away from the base, for connecting with a second drainage conduit;
• and
• a structure extending from the base for supporting the base, the structure having connection features for connection with a vertical surface in an installed position, the structure securing the base in a substantially horizontal position in the installed position.
