22-23Pump down cannot be performed when the tubing length exceeds 30m.(There is a possiblilty of generating the actuation of the excessive load protection system.)In this case, collect the refrigerant by the refrigeant collecting system.NOTE2-22-4. Indicating (marking) the indoor and outdoor unit combination numberIndicate (mark) the number after automatic address setting is completed.(1) So that the combination of each indoor unit can be easily checked when multiple units are installed,ensure that the indoor and outdoor unit numbers correspond to the system address number on the outdoorunit control PCB, and use a magic marker or similar means which cannot be easily removed to indicate thenumbers in an easily visible location on the indoor units (near the indoor unit nameplates).Example : (Outdoor) 1 – (Indoor) 1(Outdoor) 2 – (Indoor) 1(2) These numbers will be needed for maintenance. Be sure to indicate them.Installing the Remote ControllerRefer to Instruction Manual attached to the optional Wireless Remote Controller.2-23. Caution for Pump DownPump down means refrigerant gas in the system is returned to the outdoor unit.Pump down is used when the unit is to be moved, or before servicing the refrigerant circuit.This outdoor unit cannot collect more than the rated refrigerant amount asshown by the nameplate on the back.If the amount of refrigerant is more than that recommended, do not conducta pump down. In this case use another refrigerant collecting system.CAUTIONCAUTIONCaution on Pump Down (Refrigerant Recovery)(1)(2)(3)Stop the unit operetion (cooling heating wind direction, etc.).Connect the manifold gauge to the service port of the gas tube service valve.Short-circuit the PUMP pin on the outdoor unit control PCB for over 1 second.Refrigerant recovery will start and the unit starts driving.During the refrigerant recovery. LED1 blinks and LED2lights up on the outdoor unit control PCB.Remote control display shows blinks.(4) Fully close the liquid tube service valve after 2 or 3 minutes.Pump down will start.(5) When the manifold gauge reduces to 0.2 - 0.1MPa. fullyclose the gas tube service valve.Then again short-circuit the PUMP pin (CN048).Refrigerant recovery is finished.If operation is continued for over 10 minutes, the unitstops even if the refrigerant recovery is not completed.Check the liquid tube service valve closed.When the PUMP pin (CN048) is shorted again duringrefrigerant recovery the unit stops.* For protection of the compressor do not drive until theunit tubing side becomes negative pressure.PUMP pin (CN048) is locatedon the outdoor PCB as shown.Pay much attention to the fan of the outdoor unit as there is danger of injury duringoperation.
