Attach the 7/8” I .D . drain tubing provided to the drain assembly at the bottom of the humidifier . Secure with the hose clamp provided . Do not
over tighten .
Make sure the drain line has a constant downward slope from the humidifier to the drain and is not kinked or blocked .
If floor drain is not available, use condensate pump (Part #4856) to route water to a suitable drain . Provide at least 16 inches for of drain line
between the Steam Humidifier and the condensate pump .
note:
The humidifier uses cold water to temper drain water to less than 140°F .

All wiring must be installed in accordance with all governing electrical codes and with the wiring diagram provided inside the front panel .
Do not loop power wiring .
Do not use aluminum wire .
A safety grounding system that meets all governing electrical codes is required . The ground connection must be made with solid metal to metal
connections . Ground wire must be the same size as the power wiring .
With factory settings, the Steam Humidifier draws 11 .5 amps +/- 10% . Use a minimum 20 amp dedicated circuit when installing to operate at
11 .5 amps . The Steam Humidifier can be set to draw 16 .0 amps +/- 10% by repositioning dip switch #1 on the control circuit board (see
figure
13
) . When set to 16 amps, use a minimum 25 amp dedicated circuit . For both applications, size wire according to local codes .
The Steam Humidifier is shipped from the factory wired for 240 VAC operation, but it can operate on 120, 208 or 240 VAC .
If using 120V or
208V, move the black/white jumper wire to the proper tab on the control circuit board.
