the water inlet pipe is connected with the DN15 pipe (1/2 NPT). And a
DN15 metal hose is connected to the water inlet and water supply valve
of the machine.
Connect to cold water .
Provide a shut off valve in the water supply line upstream of the
steam bath generator.
Do not overheat inlet solenoid valve while welding connections.
Overheating will damage parts.
Flush inlet water line thoroughly before connection to unit.
Strainer recommended to install upstream of feed water connection
As required by local codes, install an approved backflow preventer.
Do not use PEX , PVC tubing or Aluminum-plastic tube

9
2. Steam outlet pipe(1/2’’ NPT):
The steam pipe should be installed with a metal pipe of corresponding
diameter or other materials with a high temperature resistance above
150 °C according to the steam port of the steam engine (Since the
ferrous metal and galvanized pipes will make the walls of the shower
room rusty and discolored, so they are strictly forbidden to use it). The
length of the steam pipe is no more than 3 meters. If the length exceeds 3
meters, then the pipe should be insulated.
1. Do not install any valve in steam line. Flow of steam must be
unobstructed.
2. Use 1/2” brass pipe or copper tubing from unit to steam head as
permitted by codes.
3. Insulate steam line using pipe insulation rated 250˚ F or higher.
4. Pitch steam line 1/4” per foot towards steam head or steam
generator to avoid valleys and trapping of condensation.
NOTE: Running the steam line down and then up will create a steam
trap blocking the flow of steam.
NOTE: A 1.5” hole in the shower room is required to mount the steam
head

10
3. Drain pipe and Auto drain valve ( 1 ⁄2’’ NPT)
The Auto drain System feature automatically drains the system following
each use.The auto drain is automatically turned on after the controller is
turned off for about 15 minutes, but it must be ensured that the main
power supply is not turned off.
1. Plumbing to be performed by a qualified plumber and shall be in
accordance with applicable national and local codes. Steam generator
drains by gravity. A drain line must be lower than the Auto Drain
System assembly. The Auto Drain System valve outlet is 1/2” NPT.
Check plumbing code for receptor, trap and vent requirements.
2. Use copper or brass nipple 1/2” NPT x 3 , 1 ⁄2” or longer (not
supplied) to connect Auto Drain valve. An arrow on the bottom of the
Auto Drain indicates the direction of flow
4. Steam nozzle:
Put the decorative cover on the steam nozzle in the shower room, apply
sealant and screw on the nozzle. Pay attention to avoid damaging the
decorative cover and nozzle by excessive force. Confirm that the steam
outlet of the nozzle is facing down (pointing to the ground).

11
Note: The steam nozzle should be 30cm high from the ground or 20cm
high from the edge of the bathtub. For the comfort of the shower, the
nozzle should be installed as far as possible from the seating area.
After completing the pipe installation, the electrician can carry out the
machine wiring work.
Warning:
●If the machine is installed in a place that is difficult for users to
operate, the water supply valve must be installed in a place that is easy to
operate in an emergency.
●Do not use saddle valve or needle valve to install on the water inlet
pipe. The water pipe should be unblocked and rinsed before the final
connection.
●It is strictly prohibited to install blocking valves in the steam pipe. No
obstruction or bending of the "U" channel is allowed. Otherwise,
condensed water will be generated to hinder the flow of steam. The steam
pipe should have a certain inclination when it is arranged horizontally so
that the condensed water can flow back to the steam generator or flow to
the steam nozzle.
●The steam generator cannot be installed outdoors to prevent freezing
inside. It must be installed in a place that is convenient for maintenance.
The machine should be installed horizontally with the arrow pointing up,
otherwise it cannot be turned on.
●The pipe installation must use red copper pipe material, stainless steel
pipe. It is strictly forbidden to use plastic, acrylic, aluminum-plastic tubes
or other similar materials as steam pipes. The temperature allowed by
these materials cannot reach 150°C and higher.

12
●The steam pipe entrance, all other entrances and gaps should be
sealed to prevent steam seepage and damage the machine and other
objects.
●Draining the water in the water tank into the shower room may cause
scalding accidents and damage the building materials used in the shower
room.
