Remove plastic bag from 990-13 evaporator pad, replace 16-4
distributor trough and close 16-2 cover. Turn on water supply and
check operation of humidifier. Set humidistat to a demand setting.
With the furnace off, the solenoid valve should be closed. Start the
furnace, the solenoid valve should open when the blower or burner
circuit is energized. Check flow of water through distributor trough
and evaporator pad. The solenoid valve will supply approximately 3.5
GPH of water at a line water pressure of 60 psi. Leave humidistat set
at the recommended setting.
Connect drain hose to 5/8" spout on humidifier cabinet using a 3/4" hose
clamp. Run 5/8" I.D. hose to suitable drain such as floor drain, sewer or
laundry sink. Be sure hose has continuous slope and is not kinked at any
point.
