Safety Precautions - Panasonic U-16GE2E5 Manual De Instrucciones

...In a Room
Property insulate any tubing run inside a room to
prevent "sweating" that can cause dripping and water
damage to walls and fl oors.
...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 baffl e.
...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
• Use the frame method for connecting tubing.
• Apply refrigerant lubricant to the matching surfaces of
the fl are 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.
When Servicing
• Turn the power OFF at the main power box (mains)
before opening the unit to check or repair electrical parts
and wiring.

SAFETY PRECAUTIONS

• Be sure to arrange installation from the dealer where the system was purchased or using a professional installer.
If you attempt to perform the work yourself, and do so incorrectly, there is danger of poisoning caused by exhaust
gases entering the building, as well as danger of water leakage, electric shock and fi re.
• Installation work must be performed correctly, in accordance with the instructions listed here. Hazards from
incorrect installation include dangerous exhaust gas buildup, water leakage, electric shock and fi re.
• Check the type of engine fuel used. If the wrong type of gas is used, the engine can suffer combustion problems,
and there is danger of poisoning caused by exhaust gases.
• Ventilate the area in case refrigerant gas leaks during installation work. If refrigerant gas comes into contact with
frame during the tube brazing process, toxic gas will be produced.
• When installation work is completed, check that there is no refrigerant gas leakage.
If refrigerant gas leaks into the room and contacts the frame of a fan heater, stove, burner, or other device, toxic
gases will be produced.
• Never use (top up or replace) any refrigerant other than the specifi ed refrigerant (noted on the nameplate).
Doing so may cause a rupture in or breakdown of the device, or personal injury.
• When installing or moving the A/C unit, do not allow refrigerants other than the one specifi ed (written on the
label on the unit) or air to enter the unit's refrigeration cycle.
• Always use nitrogen for the airtightness test. (Do not use oxygen-based gases.)
• Never modify or repair the system yourself.
• When handling refrigerant gas, do not come in contact with the gas directly. Doing so may result in frostbite.
• Keep your fi ngers and clothing away from any moving
parts.
• Clean up the site after you fi nish, remembering to check
that no metal scraps or bits of wiring have been left inside
the unit being serviced.

Others
• Ventilate any enclosed areas when installing or testing
the refrigeration system. Escaped refrigerant gas, on
contact with fi re or heat, can produce dangerously toxic
gas.
• Confi rm upon completing installation that no refrigerant
gas is leaking. If escaped gas comes in contact with a
stove, gas water heater, electric room heater or other
heat source, it can produce dangerously toxic gas.
