Airtight test/Air purge, etc.
For airtight test, air purge, addition of refrigerant, and gas leak check, follow the Installation Manual attached to
the outdoor unit.
REQUIREMENT
Be sure to use the tool such as charge hose exclusive to R410A.
Do not turn on the power until the airtight test and the vacuuming have fi nished.
(If turning on the power, the incorporated PMV is closed fully and the period until the vacuuming fi nishes
elongates.)
Open fully valves of the outdoor unit
Gas leak check
Check with a leak detector or soap water whether gas leaks or not, from the pipe connecting section.
REQUIREMENT
Use a leak detector manufactured exclusively for HFC refrigerant (R410A, R134a, etc.).
Heat insulating process
Perform heat insulating for each pipes separately.
In cooling time, temperature at both liquid and gas sides becomes
lower.
Therefore, perform heat insulating process suffi ciently to avoid
dewing.
• For heat insulator of pipe at gas side, be sure to use one with
heat-resisting temp. 248°F (120°C) or more.
• Using the attached heat insulating pipe, perform heat insulating
process securely for pipe connecting part of the Flow Selector
units without clearance.

REQUIREMENT
• Apply the heat insulation to the pipe connecting section of the Flow Selector unit securely up to the root without
exposure of the pipe. (The pipe exposed to the outside causes water leak.)
• Heat insulating pipe (Locally procured) must comply with applicable codes.

• Use the power cord and communication wire of specifi ed thickness, type, and protective devices required.
• Do not connect 208 - 230 V power to the terminal blocks (A, B) for communication wiring.
• Perform the electric wiring so that it does not come to contact with the high-temperature part of the pipe.
• Full disconnection under overvoltage category III conditions must be incorporated in the fi xed wiring according to
REQUIREMENT
• For power supply wiring, strictly conform to the Local Regulation in each country.
• Indoor unit side
• After connecting wires to the terminal blocks, provide a trap and fi x wires with the cord clamp.
Heat insulating pipe
• Run the refrigerant piping line and communication wiring line in the same line.
(Accessory)
• Do not turn on the power of the Flow Selector unit until vacuuming of the refrigerant pipes completes.
• Power supply circuit must be protected with safety device in accordance with local and national codes.
• Use insulated wire for the power supply wire.
