SAFETY PRECAUTIONS

  • Installation must be made in accordance with the installation manual by qualified service personnel.
    Incorrect work will cause electric shock, water leak, fire.
  • Be sure to use the attached accessories parts and specified parts for installation.
    Use of the other parts will cause electric shock, water leak, fire, the unit failing.
  • The appliance shall be installed in accordance with national wiring regulations.
    Wrong connection can cause overheating or fire.
  • After installation has complete, check that there is no leakage of refrigerant gas.
    If the refrigerant gas contact with fire, it may generate toxic gas.
  • Ventilate the room if refrigerant gas leaks during installation.
    If the refrigerant gas contact with fire, it may generate toxic gas.
  • Use the specified electrical cable.
    Make sure the cable is secured in place and that the terminals are free of any excess force from the cable. Otherwise overheating or fire may result.
  • Form the cable so that the control box cover, the cord holder and cable holder are not loose.
    Otherwise overheating, fire or electric shock may result.
  • Tighten the flare nut with a torque wrench according to the specified method.
    If the flare nut is tightened too hard, the flare nut may be broken after a long time and cause refrigerant gas leakage.
  • When installing the unit, take care not to enter air substance other than the specified refrigerant (R410A) in the refrigerant cycle.
    Otherwise, it will cause burst and injury as a result of abnormal high pressure in the refrigerant cycle.
  • Be sure to connect the refrigerant pipe before running the compressor.
    Otherwise, it will cause burst and injury as a result of abnormal high pressure in the refrigerant cycle.
  • Earth the unit.
    Incomplete earth may cause electrical shock.
  • If national legislations or type of installation requires earth leakage breaker, the legislation must be followed.
  • Arrange the drain hose to ensure smooth drainage.
    Insufficient drainage may cause wetting of the room, furniture, etc.
  • This room air/air heat pump uses refrigerant R410A.
    Use the pipe, flare nut and tools exclusively for R410A.

PUMP DOWN

(Pump down is adopted in the case of unit removal for re-installation, abandonment, repair etc.)

Pump down is to collect the refrigerant into the outdoor unit by control of the 2 and 3-way valves and the compressor.

  1. Stop the air conditioner operation.
  2. Remove both valve shaft caps of the 2 and 3-way valves.
  3. Run the air conditioner at cooling test run mode (Refer to TEST RUN). If pump down is performed at normal cooling operation, the protection system may engage and stop the operation.
  4. After 5~10 minutes, fully close the 2-way valve by turning the hexagon socket screw key clockwise.
  5. After 2~3 minutes, immediately close the 3-way valve fully.
  6. Stop the test run operation.
  7. Replace both valve shaft caps tightly.
