PLUMBING
STEP THREE:
Connect Steam Humidifier to the Cold Water Pipe
Connect one end of the remaining length of water
line to the backflow preventer. Apply a modest pull
to ensure a tight fit.
See “Reverse Osmosis Filter” on
page 24 if using the Reverse Osmosis Filter.
Connect the other end of this line to the saddle valve
or T-fitting and manual shutoff valve.
STEP FOUR:
Connect to the Water Drain
• Consult and follow local plumbing codes for drain
pipe size and maximum temperature requirement.
•
The ideal installation is directly to the main floor
drain using the rubber hose provided.
•
If direct floor drain access is not available,
see
“Other Plumbing Options” on page 16.
Connect the 1/2-inch drain hose provided to the drain
fitting on the bottom of the steam humidifier.
Use the hose clamp provided to secure the drain hose
to the barbed fitting.
Route the drain hose to the floor drain. The hose must
have a continuous downward slope.
Direct the hose outlet into the floor drain. Secure
the hose to reduce the risk of hot water pooling
or splashing.
Note: Some building codes require an air gap between
discharge hose and floor drain.
