When repairing a leak, it is recommended using oxygen free dry nitrogen with a
trace gas not exceeding 200PSI.
When accessing an R290 system, piercing valves are not to remain on the
equipment in a permanent manner. After charge is recovered, Schrader valves
are to be installed on the process stubs. Proper charge is to be weighed into the
system and the system is to be leak checked afterwards.
The R290 equipment must have red process tubes and other devices through
which the refrigerant is serviced, such as any service port. This color marking
must remain on the equipment. If marking is removed, it must be replace and
extend at least 2.5 centimeters (1”) from the compressor.

shortest hoses possible to prevent undercharging.
• Ensure the system is sealed and leak checked
• Evacuate system to a minimum 500 micron
• Weigh in correct charge
