Toshiba MMD-VNK502HEX1E Installation Manual page 7

Refrigerant piping
• Install the refrigerant pipe securely during the installation work before
operating the compressor. If the compressor is operated with the
valve open and without refrigerant pipe, the compressor sucks air and
the refrigeration cycles is over pressurized, which may cause a injury.
• Do not use any refrigerant different from the one specified for
complement or replacement. Otherwise, abnormally high pressure
may be generated in the refrigeration cycle, which may result in a
failure or explosion of the product or an injury to your body.
• Only a qualified installer (*1) or qualified service person (*1) is
allowed to do installation work. If installation is carried out by an
unqualified individual, a fire, electric shocks, injury, water leakage,
noise and/or vibration may result.
Electrical wiring
• Use wiring that meets the specifications in the Installation Manual and
the stipulations in the local regulations and laws. Use of wiring which
does not meet the specifications may give rise to electric shocks,
electrical leakage, smoking and/or a fire.
• Be sure to connect earth wire. (Grounding work)
• Incomplete earthing cause an electric shock.
• Do not connect earth wires to gas pipes, water pipes, lightning rods
or earth wires for telephone wires
• After completing the repair or relocation work, check that the earth
wires are connected properly.
• Install a circuit breaker that meets the specifications in the installation
manual and the stipulations in the local regulations and laws.
• Install the circuit breaker where it can be easily accessed by the
agent.
• When installing the circuit breaker outdoors, install one which is
designed to be used outdoors.
• When you have noticed that some kind of trouble (such as when an
error display has appeared, there is a smell of burning, abnormal
sounds are heard, the Air to Air Heat Exchanger with DX Coil Unit falls
to cool or heat, or water is leaking) has occurred in the Air to Air Heat
Exchanger with DX Coil Unit, do not touch the Air to Air Heat
Exchanger with DX Coil Unit yourself but set the circuit breaker to the
11-EN
OFF position, and contact a qualified service person (*1). Take steps
to ensure that the power will not be turned on (by marking "out of
service" near the circuit breaker, for instance) until qualified service
person arrives. Continuing to use the Air to Air Heat Exchanger with
DX Coil Unit in the trouble status may cause mechanical problems to
escalate or result in electric shocks, etc.
• Upon completion of the installation work, tell the user where the circuit
breaker is located. If the user does not know where the circuit breaker
is, he or she will not be able to turn it off in the event that trouble has
occurred in the Air to Air Heat Exchanger with DX Coil Unit.
• Use the rated voltage. Otherwise, a fire or an electric shock may
result.
• Connect power cords or connection wires securely so that the power
supply cover is attached properly. Otherwise, a fire or an electric
shock may result.
• Do not install the unit or the switch in a humid place such as a
bathroom. Otherwise, a fire or an electric shock may result.
