TUBING
Mount the self tapping saddle valve on either a cold or a hot
water pipe. A side or top mount is best to avoid clogging
from pipe sediment. Connect 1/4” O.D. tubing to the saddle
valve. Copper tubing requires a brass compression nut and
brass sleeve. Plastic tubing requires a brass insert inside the
tubing, a plastic sleeve on the outside with a brass
compression nut.
NOTE: DO NOT USE PLASTIC TUBING ON HOT WATER
OR IN CONTACT WITH ANY HOT PLENUM SURFACE OR

NOTE: If overflow protection is required, slide 5/8" I.D. vinyl
tube (Pt. No. 1099-16) over quick-drain spout and run to
suitable drain connection. Use a strain relief clamp within 36"
of humidifier to prevent drain tube from pulling on quick-drain.
Drain tube is not supplied with humidifier but is available in 5,
