Reliable comfort comes from reliable technologies
Today, Panasonic air conditioners have earned widespread acclaim throughout the world.
A rugged design ensures that the air conditioner will continue to keep the room comfortable, and operate trouble-
free for many years. Panasonic believes this is the true value of an air conditioner. And this is why we subject them
to a wide range of stringent tests.

Long-term Durability Test
The air conditioner’s main mission is to provide a level
of durability that allows it to operate reliably for years.
In order to achieve this, we conduct an accelerated test
for 10,000 hours of continuous operation. The results of
this test, which is conducted under conditions that are
much more severe than actual operating conditions,
prove the rugged strength of Panasonic air conditioners.

Compressor Disassembly Test
After a test with 10,000 hours of continuous operation,
we remove the compressor from a randomly selected
outdoor unit, disassemble it, then examine the internal
mechanisms and parts for possible failure. Panasonic
air conditioners continue to provide their designed
performance for many years even after prolonged
operation under harsh conditions.

Operating Test in Harsh Conditions
In addition to normal operating conditions, an operating
durability test is conducted in a high-temperature, high
humidity test chamber at a temperature of 55 °C. For
use in cold climates, the test is also conducted in a low
temperature test chamber at -20 °C. This test assures
that the oil inside the compressor will not freeze during
use and interrupt operation.

Waterproof Test
The outdoor unit, which is subjected to rain and wind, is
provided with IPX4 waterproof compliance.
Contact sections on printed circuit boards are also
resin-potted to prevent adverse effects caused by an
unlikely exposure to droplets of water.
