GeneralAire 1099-2 Humidifier Distributor Trough Replacement specifications:
The GeneralAire 1099LHS Humidifier may be mounted with the 7" outlet located to the right or left by inverting the cabinet and reversing the position of the distributor trough and drain pan. After the 6 cabinet screws are installed, the 4 side clips provided are used to install the distributor trough, evaporator pad and drain pan. The assembly of the distributor tube is directed into the center opening of the distributor trough cover. Water will flow through the humidifier strainer, and then metered through an orifice that provides a sufficient amount of water that is supplied to the evaporator pad and distribution trough. After starting the furnace, check the flow of the water through the distributor trough and evaporator pad.
For trouble-free humidification with maximum efficiency, after turning the water supply and electrical power off on your humidifier, remove the water distributor tube, distributor trough, evaporator pad and drain pan for proper maintenance. Clean the excessive mineral deposits from the humidifier distributor trough, cover, drain pan and humidifier cabinet. When it is time to reinstall the distributor trough and drain pan, replace the cover and distributor tube positioned over your GeneralAire 1099-2 humidifier distributor trough.
