Moving & Scrapping The Air Conditioner - Carrier XCT7 Installations- Und Benutzerhandbuch

Trial Operation & Performance
Trial operation
• Before trial operation:
Before being electrified, measure the resistor between the power terminal block (live wire and neutral wire) and
the earthed point with a multimeter, and check if it is over 1MO. If not, the unit cannot operate.
To protect the compressor, electrify the outdoor unit for at least 12 hours before the unit runs. If the crankcase
heater is not electrified for 6 hours, the compressor will not work.
Confirm if the compressor bottom is getting hot.
Except when there is only one master unit connected (no slave unit), under the other conditions, open the outdoor
operating valves (gas side, liquid side) fully. If the unit is operated without opening the valves, compressor failure
will occur.
Confirm all indoor units are being electrified. If not, water leakage will take place.
Measure the system pressure with pressure gauge, while operating the unit.
• Trial operation
In trial operation, refer to the information in the 'performance section'. When the unit cannot start up at room tem-
perature, conduct a trial operation for the outdoor unit.
Moving & Scrapping the Air Conditioner
• When moving, to disassemble and re-install the air conditioner, please contact your dealer for technical support.
• In the composition material of the air conditioner, the content of lead, mercury, hexavalent chromium, polybromi-
nated biphenyls and polybrominated diphenyl ethers are not more than 0.1% (mass fraction) and cadmium is not
more than 0.01% (mass fraction).
• Please recycle the refrigerant before scrapping, moving, setting and repairing the air conditioner. The air condi-
tioner scrapping should be handled only by qualified enterprises.
