Panasonic GHP - Precautions; Test Run Procedure

Ⅱ－3
• Check the following before performing a test run.
• Ensure that tube connections are securely attached, and that
there are no leaks.
• Ensure that shut-off valves (service valves) are open.
If a compressor is run while a shut-off valve (service valve)
is closed, the pressure will become abnormally high and
there is a risk of damage to the parts of the compressor, etc.
Additionally, if there is a leak in the connection parts, the
pressure will become even more abnormally high because of
sucked-in air, etc. and there is a risk of rupturing and injury.
