...In Moist or Uneven Locations
Use a raised concrete pad or concrete blocks to provide a solid, level foundation for the
outdoor unit. This prevents water damage and abnormal vibration.
...In an Area with High Winds
Securely anchor the outdoor unit down with bolts and a metal frame. Provide a suitable
air baffle.
...In a Snowy Area (for Heat Pump-type Systems)
Install the outdoor unit on a raised platform that is higher than drifting snow. Provide
snow vents.
...At least 1.8 m (horizontal installation)
Installation height for indoor unit shall be at least 1.8 m.
...In laundry rooms
Do not install in laundry rooms. Indoor unit is not drip proof.
When Connecting Refrigerant Tubing
Pay particular attention to refrigerant leakages.
WARNING
• When performing piping work, do not mix air except for specified refrigerant in
refrigeration cycle. It causes capacity down, and risk of explosion and injury due to
high tension inside the refrigerant cycle.
• If the refrigerant comes in contact with a flame, it produces a toxic gas.
• Do not add or replace refrigerant other than specified type. It may cause product
damage, burst and injury, etc.
• Ventilate the room immediately in the event of a refrigerant gas leakage during
installation. Be careful not to allow contact of the refrigerant gas with a flame as this will
cause the generation of toxic gas.
• Keep all tubing runs as short as possible.
• Use the flare method for connecting tubing.
• Apply refrigerant lubricant to the matching surfaces of the flare and union tubes before
connecting them, then tighten the nut with a torque wrench for a leak-free connection.
• Check carefully for leaks before starting the test run.
• Do not leak refrigerant while piping work for an installation or re-installation, and while
repairing refrigeration parts.
Handle liquid refrigerant carefully as it may cause frostbite.
• Under no circumstances shall potential sources of ignition be used in the searching or
detection of refrigerant leaks.
• A halide torch (or any other detector using a naked flame) shall not be used.
• Electronic leak detectors may be used to detect refrigerant leaks but, the sensitivity
may not be adequate, or may need re-calibration. (Detection equipment shall be
calibrated in a refrigerant-free area.)
• Ensure that the detector is not a potential source of ignition and is suitable for the
refrigerant used.
• Leak detection equipment shall be set at a percentage of the lower flammable limit
(LFL) of the refrigerant and shall be calibrated to the refrigerant employed and the
appropriate percentage of gas (25 % maximum) is confirmed.
