...In a Room
Properly insulate any tubing run inside a room to prevent "sweating" that can cause
dripping and water damage to walls and floors.
WARNING
refrigerant concentration from exceeding the safety limit in the event of refrigerant
leakage.
Consult the sales dealer regarding the appropriate measures to prevent the
allowable concentration from being exceeded.
If the refrigerant comes in contact with a flame, it produces a toxic gas and a fire.
If the refrigerant leaks and the allowable concentration is exceeded, hazards due
to a lack of oxygen in the room will result.
installed, the system must be powered off within 10 seconds from the detection.
Keep the fire alarm and the air outlet at least 1.5 m away from the unit.
CAUTION
...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.
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 a toxic gas and a fire.
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 and fire.
Keep all tubing runs as short as possible.
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.
