Precautions for the Entire Unit
WARNING
For applications such as handwashing in which hot water
directly touches hands, when using the one-pass method,
make sure to install a thermostatic mixing value at the outlet.
Failure to observe this precaution may result in burns, as water at
a temperature higher than the set temperature may flow due to
load fluctuations.
CAUTION
Install properly and DO NOT use this unit outside the
recommended operating pressure, temperature and other
specification ranges.
Improper use may result in such hazards as damage to the unit or
malfunctions that may lead to serious accidents.
When the unit is directly connected to municipal water supply
piping, back flow prevention measures must be taken in
accordance with the Water Supply Act (in Japan) or the
applicable law where the unit is to be used.
Failure to do so may lead to serious accidents in the water main
line.
The weight of the unit when empty is approximately 21 kg. If
it is difficult for one person to carry or install the product,
work with two or more people and use a lifting device so that
work can be performed safely.
Failure to do so may result in back strain or other injury if the
object should fall.
To use the unit safely and properly, read this instruction
manual carefully to carry out the specified work. Installation,
moving and incidental work of the unit requires professional
qualifications and skills. The work should be carried out by a
qualified personnel. Once installation is complete, make sure
that the work is carried out based on the instruction manual.
Work carried out improperly may lead to accidents or unit
malfunction.
Do not use well water or water from a hot spring.
Depending on the water quality, foreign matter may adhere to, or
corrosion may occur in, the unit piping, resulting in water leaks. In
this case, there will be a charge for repair work even during the
warranty period.
The unit consists of steam-using equipment and piping.
Proper insulation should be installed to avoid burns or heat
loss. Steam piping is hot, and even water piping may reach
temperatures up to 65 °C.
Insulate piping, as touching piping directly may result in burns.
The unit is not designed to withstand the surrounding piping
and equipment loads. Install the necessary piping or
equipment supports prior to unit installation, to prevent any
load being applied to the unit.
The impact of external force may damage the unit, leading to fluid
discharge, which may cause burns or other injury.
