Toshiba MMU-UP YHP-E Series Installation Manual page 8

Explanations given to user
• 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 conditioner.
• If 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.
• After the installation work, follow the Operations Manual to
explain to the customer how to use and maintain the unit.
Relocation
• Only a qualified installer(*1) or qualified service person(*1) is
allowed to relocate the air conditioner. It is dangerous for the air
conditioner 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 or other
gas to be sucked in, raising the pressure inside the refrigeration
cycle to an abnormally high level, and possibly resulting in
rupture, injury or other trouble.

CAUTION
This Air Conditioner has adopted a refrigerant HFC (R32 or
R410A) which does not destroy the ozone layer.
• As the R32 or R410A refrigerant is easily affected by impurities
such as moisture, oxidized film, oil, etc., due to the high
pressure, be careful not to allow the moisture, dirt, existing
refrigerant, refrigerating machine oil, etc., to get mixed up in the
refrigeration cycle during the installation work.
• A special tool for the R32 or R410A refrigerant is required for
installation.
• Use a new and clean piping materials for the connecting pipe
so that moisture and dirt are not mixed together during the
installation work.
• When using existing pipes, follow the Installation Manual
enclosed with the outdoor unit.
(*1) Refer to the "Definition of Qualified Installer or Qualified
Service Person."
