S
Fasten the end of the hose to the steam hose adapter
on the humidifier and the steam nozzle using metal
hose clamps, so that these do not detach due to the
high temperature.

NOTE − Maximum length of rubber steam hose is 10 ft. (3 m). Insulated copper tubing may be up to 20 ft. (6 m) in length. In all
cases, minimize sharp bends and elbows. Use 2 − 45
elbows instead of 90
elbows. Hose inner diameter = 7/8" (22 mm);
Hose outer diameter = 1−1/4" (30 mm).
