.When continuously
operating under the maximum ambient temperature 55
, the max condensing pressure and the
peak pressure should not exceed 1.75MPa and 2.17MPa.
8.5 Balance pressure 55
start the compressor the pressure in the compressor could not more
than 0.49MPa.
8.6 Do not operate the compressor before polyester is charged.
