STEAM PIPING (
1
⁄
2
" NPT)
1. DO NOT install any valve in steam piping. Flow of steam must
be unobstructed.
2. Use 1/2-inch brass pipe or copper tubing from unit to steam
head as permitted by codes.
3. Insulate steam piping with fiberglass pipe insulation or similar
insulation rated 212° F or higher.
4. Pitch steam piping1/4" per foot towards steam head or steam
generator to avoid valleys and trapping of condensate.

INSTALLATION
PLUMBING
All plumbing shall be performed by a qualified licensed plumber
and in accordance with applicable National and local codes.
1. Use unions on all pipe connections.
2. Use only brass piping or rigid copper tubing as permitted
by codes.
3. DO NOT use black, galvanized, PVC pipe or PEX except as
noted below.
WATER SUPPLY (
3
⁄
8
" NPT)
1. Connect to cold water line.
Water feed line may be flexible copper tubing,
braided hose, PVC or PEX if permissible by local codes.
2. Provide a shut off valve in the water supply line upstream of
the steambath generator.
3. DO NOT overheat inlet solenoid valve with solder connections.
Overheating will damage parts.

INSTALLATION
PLUMBING
All plumbing shall be performed by a qualified licensed
plumber and in accordance with applicable National and
local codes.
1. Use unions on all pipe connections.
2. Use only brass piping or rigid copper tubing as permitted
by codes.
3. DO NOT use black, galvanized, PVC pipe or PEX except
as noted below.
Water supply and steam piping must be flushed
to remove flux and other debris prior to connecting the
steam generator. Failure to flush the steam piping may result
in flux poisoning or a hazardous condition. Failure to flush
the steam piping may result in blockage or an inoperable
system.
WATER SUPPLY (3
⁄
8" NPT)
1. Connect to cold water line.
Water feed line may be flexible copper tubing,
braided hose, PVC or PEX if permissible by local codes.
2. Provide a shut off valve in the water supply line upstream
of the steambath generator.
3. DO NOT overheat inlet solenoid valve with solder
connections. Overheating will damage parts.
4. Flush inlet water line thoroughly before making
connection to unit.
5. Strainer recommended upstream of feed water
connection.
6. In order to reduce operating noise, reducing feed water
pres-sure to between 15 - 20 psi is recommended.
Optional pres-sure reducing valve part number 104198.
7. Provide anti-water hammer device as required.
8. Install an approved backflow preventer as required by
local codes.
DRAIN (1
⁄
2" NPT)
The drain from the generator should not share an
undersink trap, unless the generator is mounted higher than
the sink to prevent damage to the generator if the drain
backs up.
A drain valve is provided to facilitate servicing.
Provide a drain line connection from steambath generator
drain valve according to National and local Codes. Check
local plumb-ing code for receptor, trap and vent
requirements. Do not connect Drain line and Safety Valve
line together.
Unit drains by gravity.
Do not plumb the generator drain and
condensation pan drain together in such a way that will
cause drain water to back into condensation pan.
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 System valve
will open and may discharge boiling water causing a scalding
hazard.
DO NOT connect the drain valve to the steam
piping
AROMASTEAM
If the optional AromaSteam Electronic Oil Delivery System
(PN: MS AROMA) is to be installed, a 90 degree T plumbing
fitting must be installed at a designated location on the
steam piping. See the MrSteam AromaSteam Operation and
Instruction Manual (PN: 100402) for installation information
before the steam piping is installed at the technical
downloads section of www.mrsteam.com
STEAM PIPING (1
⁄
2" NPT)
1. DO NOT install any valve in steam piping. Flow of steam
must be unobstructed.
2. Use 1/2-inch brass pipe or copper tubing from unit to
steam head as permitted by codes.
3. Insulate steam piping with fiberglass pipe insulation or
similar insulation rated 212° F or higher.
4. Pitch steam piping1/4" per foot towards steam head or
steam generator to avoid valleys and trapping of
condensate.
Failure to pitch the steam piping as required for
condensate to drain, may cause condensate to block the
flow of steam. Blocking the steam flow may cause steam
pressure to discharge boiling water through the steamhead,
resulting in a scalding hazard. Blocking the flow of steam
may cause steam to discharge through the safety valve,
resulting in a scalding hazard.
A 1.5" hole in the steam room is required to
mount the steamhead. For Linear steamhead, please refer to
the installation instructions.
SAFETY VALVE (3
⁄
4" NPT)
Where permitted by local codes, provide an outlet plumbing
connection for safety valve.
To insure proper and automatic safety valve
operation: DO NOT connect a shut off valve or a plug at
safety valve outlet. DO NOT connect a shut off valve or any
obstruction in steam supply pipe. DO NOT connect the
safety-valve output into the steam piping.
CONDENSATION PAN
MrSteam strongly recommends the use of a condensation
pan in the unlikely event of a plumbing leak. Check local
plumbing codes for receptor, trap and vent requirements.
Condensation pans drain by gravity. The condensation pan is
equipped with an integral 3/4" fitting. See page 17 for
additional condensation pan installation information.
Do not plumb the generator drain and conden-
sation pan drain together in such a way that will cause drain
water to back into condensation pan.
