Toshiba RAV-SP242AT2P-UL Installation Manual page 5

WARNING
• Ask an authorized dealer or qualifi ed installation
professional to install/maintain the air conditioner.
Perform installation work properly according to the
Installation Manual.
Inappropriate installation may result in water leakage, electric
shock or fire.
• Be sure to ground the equipment
Improper grounding may cause an electric shock.
Do not connect ground wires to gas pipes, water pipes, lightning
rods or ground wires for telephone wires.
• Turn off the main power supply switch or breaker before
attempting any electrical work and maintenance.
Make sure all power switches are off. Failure to do so may
cause electric shock.
Use an exclusive power circuit for the air conditioner. Use the
rated voltage.
• When moving the air conditioner for installation to another
place, be very careful not to allow the specifi ed refrigerant
(R410A) to become mixed with any other gaseous body
into the refrigeration cycle.
If air or any other gas mixes with the refrigerant, the gas
pressure in the refrigeration cycle will become abnormally high
and it may result in the pipe bursting or personal injuries.
• Do not modify this unit by removing any of the safety
guards or by by-passing any of the safety interlock
switches.
• Do not touch the intake or aluminium fi ns of the outdoor
unit.
Doing so may result in injury.
• Tighten the fl are nut with a torque wrench in the specifi ed
manner.
Excessive tightening of the flare nut may cause a crack in the
flare nut after a long period, which may result in refrigerant
leakage.
• Install the air conditioner securely in a location where the
base can sustain the weight of the unit adequately.

• If refrigerant gas has leaked during the installation work,
ventilate the room immediately.
If the leaked refrigerant gas comes in contact with fire, noxious
gas may be generated.
• After the installation work, confi rm that refrigerant gas
does not leak.
If refrigerant gas leaks into the room and flows near a fire source,
such as a cooking range, noxious gas may be generated.
• Electrical work must be performed by a qualifi ed electrician
in accordance with the NEC or local code. Make sure the air
conditioner uses an exclusive power supply.
An insufficient power supply capacity or inappropriate installation
may cause fire.
• Use only the specifi ed wiring during the unit installation.
Ensure that all terminals are securely fi xed, so preventing
any external forces having a negative effect on the
terminals.
WARNING
• When the air conditioner cannot cool or heat a room well,
contact the dealer from whom you purchased the air
conditioner as refrigerant leakage is considered as the
cause.
In the case of repair that requires refill of refrigerant, ask
service personnel about details of the repair.
The refrigerant used in the air conditioner is harmless.
Generally, the refrigerant does not leak. However, if the
refrigerant leaks in a room and a heater or stove burner in the
room catches fire, it may generate toxic gas.
When you ask service personnel for repairing refrigerant leakage,
confi rm that the leakage portion has been completely repaired.
• Do not install the air conditioner in a location that may be
subjected to a risk of exposure to a combustible gas.
If a combustible gas leaks and becomes concentrated around
the unit, a fi re may occur.
• Install the refrigerant pipe securely during the installation
work before operating the air conditioner.
