PLUMBING INSTALLATION

WARNING! The installation of all water supply lines should be in accordance to all national and local codes by a licensed plumber.

1. Use unions when connecting pipes.

2. Use brass pipes or copper pipe only.

3. Do not use black and galvanized or PVC pipes.

WATER SUPPLY PIPE (1/2’’)

1. Connect hot water or cold water pipes. However it should not exceed 160F.

2. Install a shut off valve in the water supply line.The shut off valve should be installed in a place where it is easily accessible in
case of an emergency.

3. Flush the water supply line completely before connecting the water pipe to the steam generator, to remove any sediments in
the water.

4. Use a 3/8” steel braded flex hose with a shut off valve to connect the main waterline to the generator. See page 5 illustration

1.2.

5. The shut off valve should be open approximately 25% to reduce water pressure to the generator. The water pressure to the
generator should be between15 to 20 PSIG if necessary, decrease the pressure accordingly.

6. If necessary, install a Hydro pneumatic device which reduces pressure spikes.

7. Do not use PEX or PVC tubing.

STEAM PIPE (3/4’’)

1. Do not install any stop valves in the steam pipes. The steam can never be obstructed.

2. Install a 3/4” copper or brass pipe between the steam generator and the steam nozzle.

3. If needed, the heat insulation material used to insulate the steam pipe should be resistant to temperatures as high as 240F or
higher.

4. The shorter the distance, the better. Use curved elbows when connecting pipes to allow the steam to flow smoothly through
the steam pipe.

STEAM HEAD (3/4’’)

ATTENTION! Steam Head and the steam outlet gets very hot, try to avoid installing the steam head in a position which will easily

come into contact with the person bathing.

1. Install the steam head approximately 12 inches above the ground floor. If the steam room material is acrylic or non-heat­resistant sheet, please consult with material manufacturer about steam room applications.

2. The steam head outlet should be installed face down. To prevent scalding bather with steam or water.

ATTENTION! Tighten steam head by hand. Do not use a spanner or other tools, use a little soap water and soft sponge to wipe,

and do not use erosive chemical solutions or crude cleaning tools.

IMPORTANT!

1. Please consult manufacturer of materials like acrylic, fiber glass or other anti-heat sheet about the installation of the steam
head.

2. In the entire steam room, it is required that steam does not leak out. The pipes, its accessories and the holes should be air
proof by applying sealant so that no steam will enter the holes in the wall.

DRAINPIPE (1/2’’)

ACCORDING TO THE NATIONAL AND LOCAL PLUMBING CODES: The steam generator drain valve should be equipped with

a drainpipe. The steam generator drains the water by gravity.Check local code requirements for drain valves. Do not connect the
safety valve or steam line to drain line.

SAFETY VALVE (3/4’’)

1. Safety valve is an automatic system that is actuated by pressure in order to prevent steam pressure increasing in the interior
of the generator .

2. The pressure limit range of the safety valve is 15 PSIG and the pressure will begin to decrease if pressure should come over
this value.

3. If it is allowed by local codes, provide the safety valve with exterior drainpipe.

4. Do not dismantle the pressure relief valve while generator is in operation..

5. To maintain the proper automatic operation of the safety valve, make sure the safety valve connection pipe is smooth.

CONTROL PANEL OPERATION

The control panel has a digital temperature control system which can start, stop or pause in the
preset time to keep the temperature at the set number.

ON/OFF

When system is powered, all functions will still not be activated and remain in a waiting state.
Digital tube will display ---- . In the waiting state, press the button to turn on the system and
activate steam function. System will recall last use steam time and TEMP, system begins to count
down. During this time, the digital tube will display the ambient temperature. Steam temperature
display range is 32° F-140° F.

When the actual temperature is lower or equal to 32° F, the digital tube will display 32° F. When
the actual temperature is higher or equal to 140° F, the digital tube will display 140° F. The last
digit displays as the unit of Fahrenheit temperature. The default steam time is 30 minutes.
When lacking water, the heating elements will stop heating and the water inlet valve will work
automatically. If there is no water detected in 5 seconds or the water coming in does not reach
the set point in 15 seconds, the digital tube will display to indicate an error of not enough
water cycling. If there is enough water cycling, the steam function will return to normal. When
the steam function is started, if the ambient room temperature is higher than the set point, the
heating element will stop heating, the digital tube will flash to display the current environment
temperature; when the environment temperature is lower than the set point, the heating element
will work again, the digital tube will display current room temperature normally.
When the system is on, press button to turn off the system, or when the steam time is over
the system shuts off. 10 minutes after the system is shut off, the drainage function will be started
automatically for 7 minutes.

TIME AND TEMPERATURE SETTING

When system is on, pressing the button will cycle the system between the Time setting,
Temperature limit setting, and ambient TEMP display on the LED screen. When system is
powered on, press button one time to adjust Steam time. Its range is 1-60 minutes, with
1 minute intervals, which can be adjusted using the and arrow keys. If there is no
adjustment in 5 seconds, the system will exit time setting automatically and the LED will display
current ambient TEMP. Pressing the twice will allow you to set the Temperature limit setting.
During this time, press or to adjust steam TEMP. Its range is 50°~130° Fahrenheit,
with 1° increments. If no adjustment is done in 5 seconds, the system will exit the TEMP setting
automatically, and the LED screen will display ambient temperature.
