Toshiba MMW-AP0481CHQ-E Service Manual page 10

Only a qualified installer (*1) or qualified service person (*1) is allowed to install the hot water module. If the hot
water module is installed by an unqualified individual, a fire, electric shocks, injury, water leakage, noise and / or
vibration may result.
Before starting to install the hot water module, read carefully through the Installation Manual, and follow its
instructions to install the hot water module.
Be sure to use the company-specified products for the separately purchased parts. Use of non-specified
products may result in fire, electric shock, water leakage or other failure. Have the installation performed by a
qualified installer.
Do not supply power from the power terminal block equipped on the outdoor unit to another outdoor unit.
Capacity overflow may occur on the terminal block and may result in fire.
Do not install the hot water module in a location that may be subject to a risk of exposure to a combustible gas.
If a combustible gas leaks and becomes concentrated around the unit, a fire may occur.
Installation
Do not install water pipes in a location that is susceptible to freezing.
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 qualified service person (*1).
If you install the unit in a small room, take appropriate measures to prevent the refrigerant from exceeding the
limit concentration even if it leaks. Consult the dealer from whom you purchased the hot water module when you
implement the measures. Accumulation of highly concentrated refrigerant may cause an oxygen deficiency
accident.
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.
Explanations given to user
If you have discovered that the fan grille is damaged, do not approach the outdoor unit but set the circuit
breaker to the OFF position, and contact a qualified service person to have the repairs done.
Do not set the circuit breaker to the ON position until the repairs are completed.
Relocation
• Only a qualified installer (*1) or qualified service person (*1) is allowed to relocate the hot water module.
It is dangerous for the hot water module to be relocated by an unqualified individual since a fire, electric
shocks, injury, water leakage, noise and / or vibration may result.
• When carrying out the pump-down work, shut down the compressor before disconnecting the refrigerant pipe.
Disconnecting the refrigerant pipe with the service valve left open and the compressor still operating will
cause air, etc. to be sucked in, raising the pressure inside the refrigeration cycle to an abnormally high level,
and possibly resulting in reputing, injury, etc.
