PRECAUTIONS FOR SAFETY
The four indoor units of TOSHIBA simultaneous double twin packaged air conditioning
system are the same units. Set and install the header and follower units taking the
installation site into consideration. (Be certain to use the new refrigerant R410A in the
indoor units.) The indoor unit connected to the remote controller will be the header unit.
•
Ensure that all Local, National and International regulations are satisfied.
•
Read indoor, outdoor installation manual and this manual carefully before Installation.
•
The precautions described below include the important items regarding safety. Observe
them without fail.
•
After the installation work, perform a trial operation to check for any problem.
Follow the Owner's Manual to explain how to use and maintain the unit to the customer.
•
Turn off the main power supply switch (or breaker) before the unit maintenance.
•
Ask the customer to keep the Installation Manual together with the Owner's Manual.
WARNING
•
Ask an authorized dealer or qualified installation professional to install/maintain
the air conditioner.
Inappropriate installation may result in water leakage, electric shock or fire.
•
Turn off the main power supply switch or breaker before attempting any electrical
work.
Make sure all power switches are off. Failure to do so may cause electric shock.
•
Connect the connecting cable correctly.
If the connecting cable is connected in a wrong way, electric parts may be damaged.
•
When moving the air conditioner for the installation into another place, be very
careful not to enter any gaseous matter other than the specified refrigerant into
the refrigeration cycle.
If air or any other gas is mixed in the refrigerant, the gas pressure in the refrigeration
cycle becomes abnormally high and it resultantly causes pipe burst and injuries on
persons.
•
Do not modify this unit by removing any of the safety guards or by by-passing any
of the safety interlock switches.
•
Exposure of unit to water or other moisture before installation may cause a short-
circuit of electrical parts.
Do not store it in a wet basement or expose to rain or water.
•
After unpacking the units, examine them carefully if there are possible damage.
•
Do not install in a place that might increase the vibration of the unit.
•
To avoid personal injury (with sharp edges), be careful when handling parts.
•
Perform installation work properly according to the Installation Manual.
Inappropriate installation may result in water leakage, electric shock or fire.
•
When the air conditioner is installed in a small room, provide appropriate
measures to ensure that the concentration of refrigerant leakage occur in the
room does not exceed the critical level.
