Precautions for Electrical Wiring
Power is supplied at 100 V AC 50/60 Hz or 200 V AC 50/60
Hz.
Use of a power supply outside the above specification range
may cause fires or electric shock.
Make sure the power supply is OFF before carrying out
work on the wiring or inspections involving
disassembly.
If such work is carried out with the power on, there is a
danger that unit may malfunction or electric shock may
occur, leading to injury or other accidents.
Make sure that wiring work requiring a special license is
carried out by qualified personnel.
Incorrect wiring work may result in generating heat from the
wiring, with the risk of injuries, burns, fire or damage due to
electrical leaks, etc.
Do not allow any cables or wires to come into contact
with the steam piping.
Steam heat will sever wiring, which may result in injury,
burns, fire, damage, etc. caused by electric shock from the
wiring.
Precautions for Commissioning
When starting up the unit, make sure to check the
display for the measured temperature and do not touch
the water until the temperature becomes stable at a
temperature higher than the set temperature may flow.
Failure to observe these precautions is dangerous and may
result in burns.
The tank must be full of water before operating the heat
exchanger. In particular, if water has been discharged
from inside the heat exchanger for freeze prevention
etc., make sure to restart the unit after supplying water
to the heat exchanger. (When the cooling circulation unit
(optional) is installed.)
Operating the heat exchanger empty of water for a long
period of time is dangerous, and may result in the pump
running dry and becoming damaged.
Operation should be carried out by an experienced
person with such as a steam and water piping
technician or an electrician, ensuring to wear a pair 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.
