PRESSURE TESTING
11. Pressure test with dry nitrogen to detect leaks. Use
nitrogen and a trace amount of refrigerant to locate
the leak if a pressure test indicates a leak is present.
12. Do not over pressurize the system. Check the name
plate for the maximum test pressure.
DANGER
Failure to properly purge or pressure test a system
for leaks, can result in serious injury or death from
explosion, fire, or contact with refrigerant or lubricant
mists.
EVACUATION
13. Slowly release the nitrogen and evacuate to a
minimum of 500 microns.
NOTE: Do not start the compressor while it is in a vacuum
or energize the compressor with the terminal cover off.
Always break a vacuum with refrigerant before energizing
(starting) the compressor.
