Operation On a call for humidity the Model 800 Residential Steam Humidifier provides power to the Model 850 Fan Pack. The Model 850 blower distributes the steam to the room. When the call for humidity ends and the humidifier stops producing steam, the Model 850 Fan Pack will continue to operate for 2 minutes to distribute the remaining steam before de-activating.

INSTALLATION INSTRUCTIONS (continued) location (continued) Six feet of steam hose is provided with the Model 800 Steam Humidifier. If the Fan Pack is mounted more than six feet from the Humidifier, splice in 1” copper pipe as shown in Figure 3. Due to condensation inside the hose or pipe, the output of the Fan Pack depends on the length of the steam hose or pipe connecting it to the Humidifier. When the humidifier is wired to 120 volts, the fan pack will deliver 11.

INSTALLATION INSTRUCTIONS (continued) Mount Housing The Model 850 Fan Pack installs between the studs of a standard 16” on-center wall. Drywall on both sides of the wall must be removed for piping and wiring the Model 850. To ensure proper operation, the Model 850 must be mounted level. Use the four 1-1/2” mounting screws provided to attach the housing to the wall studs. See Figure 5.
