Precautions for the Entire Unit
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.
Local regulations may restrict the use of the unit to below the
conditions quoted.
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).
Failure to do so may lead to serious accidents in the water main line.
Use hoisting equipment for heavy objects (weighing
approximately 20 kg or more)
.
Failure to do so may result in back strain or other injury if the
object should fall.
Take measures to prevent people from coming into direct
contact with the condensate outlet of the unit.
Failure to do so may result in burns or other injury from the
discharge of fluids.
When disassembling or removing the unit and its
components, wait until the internal pressure equals
atmospheric pressure and the surface of the components
have cooled to room temperature
.
Disassembling or removing components when hot or under
pressure may lead to discharge of fluids, causing burns, other
injuries or damage.
Be sure to use only the recommended components when
repairing the unit, and NEVER attempt to modify the unit in
any way.
Failure to observe these precautions may result in damage to the
unit and burns or other injury due to malfunction or the discharge
of fluids.
Do not use excessive force when connecting threaded pipes
to the unit.
Over-tightening may cause breakage leading to fluid discharge,
which may cause burns or other injury.
Use only under conditions in which no freeze-up will occur.
Freezing may damage the unit, leading to fluid discharge, which
may cause burns or other injury.
Use only under conditions in which no water hammer will
occur.
The impact of water hammer may damage the unit, leading to
fluid discharge, which may cause burns or other injury.
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 components 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.
If carried out by unqualified personnel, overheating or short
circuits leading to injury, fires, damage or other accidents may
occur.
