Scope of this manual
This manual describes how to start up and switch off the unit, set

controller, maintain the unit and solve operational problems.
DANGER: ELECTRICAL SHOCK
Switch off all power supply before removing the switchbox
service panel or before making any connections or
touching electrical parts.
Do not touch any switch with wet fingers. Touching a switch
with wet fingers can cause electrical shock. Before
touching electrical parts, turn off all applicable power
supply.
To avoid electric shock, be sure to disconnect the power
supply 1 minute or more before servicing the electrical
parts. Even after 1 minute, always measure the voltage at
the terminals of main circuit capacitors or electrical parts
and, before touching, be sure that those voltages are
50 V DC or less.
When service panels are removed, live parts can easily be
touched by accident. Never leave the unit unattended
during installation or servicing when the service panel is
removed.
DANGER: DO NOT TOUCH PIPING AND INTERNAL
PARTS
Do not touch the refrigerant piping, water piping or internal
parts during and immediately after operation. The piping
and internal parts may be hot or cold depending on the
working condition of the unit.
Your hand may suffer burns or frostbite if you touch the
piping or internal parts. To avoid injury, give the piping and
internal parts time to return to normal temperature or, if
you must touch them, be sure to wear protective gloves.
