5.ALWAYS supply and install a shut off valve in the water supply line dedicated to the humidifier to facilitate servicing. Use ½" OD copper to within 4 feet of the humidifier. Reduce copper to 3/8" OD and connect to the
DRAIN LINE
1.Humidifier is equipped with a 7/8" O.D. unthreaded drain outlet on underside of drain canal on bottom of the humidifier (see Figure #15). A supplied reducer (see Figure #16)or equivalent shall be installed on the drain line. It will prevent backup in the drain pan and in the cylinder due to partially blocked or badly installed drain lines. This prevents rusting of the drain pan and arcing due to

codes prohibit it. Route to a floor drain or equivalent for safety reasons, since drain water from humidifier can be very hot.
3.Keep drain lines as short as possible. Keep drain lines sloped down, not level and not up since low spots in drain lines will accumulate sediment and cause backup. The drain line should be 1" O.D. copper pipe or larger. Do not use plastic pipe for drain lines.
STEAM LINE
1.Steam lines for SGH models 010 through 020 require a minimum 7/8" O.D. (nominal 3/4") copper pipe. For steam runs longer than 20 ft use insulated nominal 1" copper to ensure the draining of condensate.

NOTE: Steam hose should not reach bottom of the funnel. In the event the building drain is plugged this becomes an overflow point.
2.The drain line should not end in a sink used frequently by personnel, or where plumbing
NOTE: Trap must be 3' minimum down from steam distributor. If not, condensate must be routed to drain.
