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.

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.
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 con-
nect Drain line and Safety Valve line together.
Unit drains by
gravity.
Do not plumb the generator drain and condensa-
tion 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
