OPTIONAL DRAIN PAN
M
r. Steam strongly recommends the use of a drain pan in the unlikely
event of a plumbing leak.
Locate the drain pan on a solid level surface and place the steam generator
inside the drain pan. Insure the steam generator is level (see page

for
locating the steam generator).
All plumbing shall be performed by a qualified licensed plumber and in
accordance with applicable national and local codes. Check local plumbing
code for receptor, trap and vent requirements. Drain pans drain by gravity.
The drain pan is equipped with an integral female
3
⁄4" NPT fitting.

equipped with a low power heating element and
thermostat to keep the water in the tank warm
enough to bring up steam quicker. All express
steam components and wiring are installed at the

required by installers.
