GFCI must be installed on the power supply, and the power supply, power wire, fuse and
breaker must comply with the nameplate on the unit and table 2 in this manual.
The solenoid valve can endure maximum 0.8MPa (8kg/cm2) water pressure. To protect the
solenoid valve from extremely high water pressure, please turn down the inlet slightly or install
water pressure relieving valve.
Do not install saddle-backed or needle valves on the inlet. Please dredge and clean the pipe
before installation.
No block valve should be installed in the steam pipelines. Strictly no blocked or blended pipe,
otherwise have negative effect on the flow of steam and condensate. The steam pipelines
should be installed with a slight angle so that the condensate can flow back to the generator or
the steam head.
Steam generator should be installed indoor to avoid frozen. The generator should be installed
and leveled with the arrow pointing upward at an easy-access place, otherwise do not switch
on.
The steam pipeline must be copper pipes or stainless steel pipes, all other material such as
plastic, acrylic should not be used since they cannot endure 150℃or higher temperature.
All inlet and apertures should be sealed to prevent any leakage of steam and to protect the
generator and customers.
Don’t drain water to the steam room from the water tank as may cause serious scald and
damage the steam room.

Notice:
The rated power is measured under single phase 230V, therefore the actual operating power
under single phase 215-240V, 50/60Hz, or three phases 380-415V, 50/60Hz may be different
from the rated value.
3KW and 4KW machine, can be only under 215-240V single phase. Please note the earth wire
should not less than 1.5mm2.
From 4.5KW to 8KW machine, can be made as 215-240V single phase or 380-415V three phases.
Please note the earth wire should not less than 1.5mm2, the live wire and null wire should not
less than 2.5mm2.
More than 9KW machine, can be only under 380-415V three phases. Please note the earth wire
should not less than 2.5mm2, the live wire and null wire should not less than 4.0mm2.
How to choose the right KW steam generator?
Step One: Calculate the steam room m³, (Length*Width*Height) in meter.
(1 feet = 0.3048 meter,1 inch=0.0254 meter)
Step Two: Check your steam room materials
If Acrylic, steam generator KW= steam room m³
If Ceramic Tile, steam generator KW= 1.30 X steam room m³
If All Glass tile or Glass Block Walls, steam generator KW= 1.35 X steam room m³
If Porcelain tile, steam generator KW= 1.6 X steam room m³
If Natural stone tiles* up to 1/2″, steam generator KW= 2 X steam room m³
If Natural stone slabs over 1/2″, steam generator KW= 2.25 X steam room m³

the water inlet valve.
Attention: Only use cold water supply.
ii. Drain Outlet
Please use 3/4’’ copper pipe or stainless steel pipe to connect the drain outlet and the drain
pipeline of the house. The drain pipeline should be installed with small angle so as to help
residual water in the steam generator flow to the drain pipe.
Attention: Don’t use locking pliers to over tight the drain pipe connection. Just make sure it
without leakage under Teflon tape sealing. The water come out from the steam generator will
over 100℃. Don’t use the plastic pipe/acrylic pipe/FRP pipe or other similar material pipe.
iii. Steam outlet
Please use copper or stainless steel pipe to connect the steam head and the steam outlet pipe of
the generator. The pipe should be less than 3 meters long and minimize the number of elbows,
otherwise heat isolating methods should be implemented.
For 3KW-6KW steam generator, steam outlet is 1/2’’, please AT LEAST use 1/2’’ steam pipe,
must be stainless steel pipe or copper pipe.
For 7KW-13.5KW steam generator, steam outlet is 3/4’’, please AT LEAST use 3/4’’ steam pipe,
must be stainless steel pipe or copper pipe.
For 15KW-24KW steam generator, steam outlets are TWO 3/4’’ , please AT LEAST use TWO
SEPARATE 3/4’’ steam pipes, don’t cross the two steam pipes, must be stainless steel pipe or
copper pipe.
Attention: Please MUST choose right diameter steam pipe, as if the pipe size is smaller than
our instruction, it may cause the steam generator internal pressure to increase suddenly which
may damage the steam generator and have safety risk.
iv. Safety Valve
It’s to release the pressure of steam generator, use 1/2’’ copper pipe or stainless steel pipe to
connect the safety valve and the drain pipeline of the house. Please don’t block it.
v. Steam Head
The steam head should be about 300mm from the ground and at least 150mm from customer
