Electric boiler design in the STN330300 and ordinary A5 / AB5 STN332310 environment
(namely the temperature range from + 5
℃
to 40
℃
, humidity depends on temperature,
maximum 85%). The boiler shall not be installed in the 0, 1 and 2 areas of STN332135-1,
nor shall it be installed in any room, bathroom, washing area or shower room with a
bathtub. However, where it can be installed 3 area, such as if possible to clean the water
(as in schools, factories, sports clubs and used in the public service area public drinking
hole, pipe and nozzle, etc.), also can't install electric boiler.
If the boiler is installed in an acceptable place, it will provide protection against
current accidents at the same time.
2.2 boiler installation
To hang the boiler on the wall, it is
recommended to use the expansion
screw (the delivery attachment), which
should be fixed on the wall in advance
(see figure 6). The main body of the
heater structure with water pump and
accessories shall be suspended on the
fixed expansion screw. The boiler cover
is connected to the back wall by screws
and can be disassembled. Such a place
should be determined before the boiler is
installed, where there may be necessary
repair work without any major limitations.
If the boiler is to be installed in an open
system, the water column of the heating
system should produce at least 1 bar
pressure.
