CAUTION
Unit components such as steam piping may become hot
during operation.
Do not touch components with bare hands.
In the event of an earthquake, close the main steam supply
valve and shut down the unit promptly.
If the tube inside the heat exchanger of this unit is damaged
due to an earthquake, a large amount of steam will enter the
hot water piping, which may result in burns.
Valve and unit operation must be carried out by personnel who
have attended operation training ensuring the use of
heat-resistant gloves, helmet, protective glasses, etc. to
prevent burns.
Failure to do so may result in burns, as the piping and cover of the
unit become hot during operation.
When finishing operation, the operation should be stopped in
accordance with the proper steps.
Incorrect operation of the unit during use for hand washing,
showering, or cleaning, etc., may result in burns due to malfunction,
which causes the temperature of the water to rise above the set
temperature.
When draining water from the unit, make sure to wait until the
unit has cooled down.
If carrying out work after hot water use, there is a risk of burns, as
the components and the water inside the unit are hot.
Precautions when the Unit is Shut Down for a Long Period of Time
CAUTION
When the unit is shut down for a long period of time or there
is a possibility of freezing, make sure to completely
discharge steam condensate or water in the unit and its
components such as the steam piping, heat exchanger, etc.
After doing so, there is a risk of burns or injury during operation
start-up, as fluid may be discharged from piping.
Precautions when Maintenance or Inspection is Conducted
CAUTION
Be sure to use only the recommended components when
repairing the unit and its components, and NEVER attempt to
modify the unit in any way.
Failure to observe these precautions may result in damage to the
unit or burns or other injury due to malfunction or the discharge of
fluids.
Do not apply excessive force to the unit, pipings, and
peripheral piping.
Failure to do so may result in injury or deformation of the device.
When disassembling or removing the unit, wait until the
internal pressure equals atmospheric pressure and the
surface of the unit has cooled to room temperature.
Disassembling or removing the unit when it is hot or under
pressure may lead to discharge of fluids, causing burns, other
injuries or damage.
Make sure to wear protective gear such as a helmet, safety
glasses, long-sleeve shirt, heat-resistant gloves, protective
footwear, etc.
Failure to do so may result in burns or injuries.
