Installation Procedure
Before Installing the Solar Thermal Kit
CAUTION
• Pipe diameter of the solar thermal system : The tee pipe of the solar kit is 22 mm
in diameter. If the diameters between the pipe of the solar thermal system and
tee pipe of the solar kit are different, a pipe diameter reducer or expander, which
is supplied in the field, will be required.
• Working space for pipe welding or pipe cutting : The tee pipe of the solar kit
should be inserted into the existing pipe of the solar thermal system. To do the
insert job, cutting of the existing solar thermal system pipe and welding of the
existing solar thermal system pipe and tee pipe of the solar kit are required after
securing enough working space.
• Preparation for working fluid drainage and refilling : While installing the solar kit,
drainage of working fluid and refilling are required. Be ready to do these jobs.
