9. INSTALLATION PROCEDURE
For general public use
Power supply cord of parts of appliance for Outdoor use shall be more than polychloroprene sheathed flexible cord (design H07RN-F), or cord
designation 245IEC66. (1.5 mm
2
or more)
CAUTION
•
THIS AIR CONDTIONER ADOPTS THE NEW HFC REFRIGERANT (R-410A) WHICH DOES NOT DESTROY OZONE LAYER.
R-410A refrigerant is apt to be affected by impurity such as water, oxidizing membrane, and oils because pressure of R-410A refrigerant
is approx. 1,6 times of refrigerant R-22. Accompanied with adoption of the new refrigerant, refrigerating machine oil has been also changed.
Therefore, during installation work, be sure that water, dust, former refrigerant, or refrigerating machine oil does not enter into the refrigerating
cycle or new-refrigerant air coditioner.
To prevent mixin of refrigerant or refrigerating machine oil, the sizes of connecting sections of charging port of the main unit or installation tools are
different from those for the coventional refrigerant. Accordingly, the exclusive tools are required for the new refrigerant (R-410A) as shown below.
For conecting pipes, use new and clean piping materials with high pressure-tight force, which were made fro R-410A only, so that water or dust
does not enter. Moreover, do not use the existing piping because there are problems about pressure-tight forec and inner impurity in the existing
piping.

9-1. Safety Cautions
DANGER
•
FOR USE BY QUALIFIED PERSONS ONLY.
•
TURN OFF MAIN POWER SUPPLY 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 BY WRONG WAY, ELECTRIC PARTS
MAY BE DAMAGED.
•
CHECK THE EARTH WIRE IS NOT BROKEN OR DISCONNECTED BEFORE INSTALLATION.
•
DO NOT INSTALL NEAR CONCENTRATIONS OF COMBUSTIBLE GAS OR GAS VAPORS.
FAILURE TO FOLLOW THIS INSTRUCTION CAN RESULT IN FIRE OR EXPLOSION.
•
TO PREVENT OVERHEATING THE INDOOR UNIT AND CAUSING A FIRE HAZARD, PLACE THE UNIT WELL AWAY (MORE THAN 2 M)
FROM HEAT SOURCES SUCH AS RADIATORS, HEAT REGISTORS, FURNACE, STOVES, ETC.
•
WHEN MOVING THE AIR-CONDITIONER FOR INSTALLING IT IN ANOTHER PLACE AGAIN, BE VERY CAREFUL NOT TO GET THE
SPECIFIED REFRIGERANT WITH ANY OTHER GASEOUS BODY 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
RESULTINGLY CAUSES BURST OF THE PIPE AND INJURIES ON PERSONS.
•
IN THE EVENT THAT THE REFRIGERANT GAS LEAKS OUT OF THE PIPE DURING THE INSTALLATION WORK, IMMEDIATELY LET
FRESH AIR INTO THE ROOM. IF THE REFRIGERANT GAS IS HEATED BY FIRE OR SOMETHING ELSE, IT CAUSES GENERATION OF
POISONOUS GAS.
WARNING
•
Never modify this unit by removing any of the safety guards or by by-passing any of the safety interlock switches.
•
Do not install in a place which cannot bear the weight of the unit.
Personal injury and property damage can result if the unit falls.
•
Before doing the electrical work, attach an approved plug to the power supply cord.
And, make sure the equipment to be earthed.
•
Appliance shall be installed in accordance with national wiring regulations.
If you detect any damage, do not install the unit. Contact your Toshiba dealer immediately.
CAUTION
•
Exposure of unit to water or other moisture before installation will result in an electrical short.
Do not store in a wet basement or expose to rain or water.
•
After unpacking the unit, examine it carefully for possible damage.
•
Do not install in a place that can increase the vibration of the unit. Do not install in a place that can amplify the noise level of the unit or where
noise and discharged air might disturb neighbors.
•
To avoid personal injury, be careful when handling parts with sharp edges.
•
Please read this installation manual carefully before installing the unit. It contains further important instructions for proper installation.
CAUTION
This appliance must be connected to the main power supply by means of a circuit breaker or a switch with a contact separation of at least 3 mm.
The installation fuse (25A D type
) must be used for the power supply line of this air conditioner.
TO DISCONNECT THE APPLIANCE FROM THE MAIN POWER SUPPLY.
