DRAIN
(1" NPT)
Applies to 1-3
1. Do not connect the generator drain line to an
undersink trap.
2. Do not drain into a steam enclosure or any location where
accidental contact with drain water may occur. In the event
of a power failure the AutoFlush valve will open and may
discharge boiling water causing a scalding hazard.
3. Do not connect the drain valve to the steam piping.
Connecting the drain line to the steam piping may allow
boiling water to discharge through the steamhead causing
a scalding hazard.
Applies to 4-8
4. A drain valve is provided to facilitate maintenance and
servicing. Provide a drain line connection from steambath
generator drain valve according to National and Local Codes.
5. Check local plumbing code for receptor, trap and vent
requirements.
6. Do not connect Drain line and Safety Valve line together.
7. The steam generator drains by gravity. Plumb all drain lines
accordingly.
8. See page 20 for installation of the optional Condensation
Pan.

1. All plumbing shall be performed by a qualified licensed
plumber and in accordance with applicable National
and local codes.
Applies to 2-4
2. Use unions on all pipe connections as required for serv-

3. Use only brass piping or rigid copper tubing. Use only
piping as permitted by codes.
4. Do not use black, galvanized, PVC pipe or PEX except
as noted below.
Applies to 1-9
1. Install a shut off valve in the water supply line.
2. It is recommended to install a strainer in the water
supply line.
3. Install an anti-water hammer device as required.
