Simple Check for Failure Diagnosis

Diagnosis Result
1
Check to see if the OPERATION indicator goes on OPERATION and off when the main switch or breaker is turned on. INDICATOR (Check the primary and secondary voltage of the transformer. )
2
Check the power supply voltage between 1 and 2 . [. . . ] 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.
CAUTION
TO DISCONNECT THE APPLIANCE FROM THE MAIN POWER SUPPLY.
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) must be used for the power supply line of this air conditioner.
DANGER
· FOR USE BY QUALIFIED PERSONS ONLY. · TURN OFF MAIN POWER SUPPLY BEFORE ATTEMPTING ANY ELECTRICAL WORK. 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. · 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. It is necessary to use an adapter to prevent vacuum pump oil from flowing back to the charge hose. The charge hose connecting part has two ports-one for conventional refrigerant (7/16 UNF 20 threads per inch) and one for R410A. If the vacuum pump oil (mineral) mixes with R-410A a sludge may occur and damage the equipment. Exclusive for HFC refrigerant.

· Incidentally, the "refrigerant cylinder" comes with the refrigerant designation (R-410A) and protector coating in the U. S's ARI specified rose color (ARI color code: PMS 507). · Also, the "charge port and packing for refrigerant cylinder" require 1/2 UNF 20 threads per inch corresponding to the charge hose's port size.
