correct steam generator model and size are as critical as design of the steam room itself. The power
supply and circuit protector should be carefully checked to match the parameters of the generator.
Please referring to the table below and select the suitable model for your specification.
Power Room size
kW
4.0 124～194
6.0 177～247
9.0 283～388
12.0 388～495
2. Installation of steam generator
 Switch off all power supply before installation, and check whether you have the correct model
for your steam room according to table 3.
 Do not install the generator outdoors, in wet/moist place, freezing, or corrosive place. Do not
install the generator near to inflammables such oil paint, diluents and fuel. Be alert to the steam
pipeline and safety valve since the high temperature of steam is dangerous to customers.
 Generator must be level installed.
 The generator should be installed in a dry and well-ventilated place. It can be installed either on
the wall or on the ground, but must be well-fixed. Install the generator as close to steam room as
possible, such as in the closet, under the washing basin or in the basement. (Refer to figure 4).
i. Install the generator on the wall: drill two small holes on the wall, insert the expansion
screws and then hang the generator on those screws.
ii. Install the generator on the ground or deck: Install the frame on the site and then screw the
generator into the frame.
iii. For better service and maintenance, please install the generator with the nameplate face to
front and leave more than 10＂ space around the generator.
3. Installation of controller and temperature sensor
The controller should be installed with height of 47＂ outside the steam room but nearby or
other place where easy to operate. Firstly drill a hole with diameter 50mm (2 inch) on the
installation site, pull the control wire and temperature sensor wire through the conduit, then connect
the control wire to the black connector(6P) while connect the temperature sensor wire to the black
connector(2P). Finally the controller panel can be glued to wall by the double sided adhesive on the
back of the panel (Refer to figure 5).
The temperature sensor is used to measure the temperature inside the steam room, so that the
generator can work automatically according to the pre-set temperature and maintain the room
temperature constant. The installation height of the sensor should be about 47-59＂ from ground.
Please drill a ￠16mm (diameter 5/8‟‟ ) hole, and then nail down the sensor in the steam room
(Refer to figure6),, and pull the sensor wire through the conduit then connect to the black
connector(2P) of the controller.
