
When sweat connections are made in the connecting lines, be sure that the inside of the
tubing is clean before installing the unit. Use a dry nitrogen bleed during brazing. Note
that compressor suction and discharge valves should be open to atmosphere no longer
than 15 minutes. Compressors with POE (polyolester) oil will quickly become
contaminated when opened to atmosphere. On any installation, the use of a suction
line filter, liquid line filter drier and moisture indicator is recommended. If the suction
line is larger than one-quarter inch, a vibration eliminator should be installed close to
the motor compressor in a horizontal parallel to the compressor, crankshaft or in a
vertical position 90 degrees to compressor crankshaft.
NOTE: The suction line should be clamped near the inlet end of the vibration
eliminator. The vibration eliminator is located between the clamp and the
compressor

Notes:

Line lengths are expressed in equivalent feet = actual run length + fitting
allowances (i.e. ~5’ for each bend/elbow allowance).

Use only refrigeration grade dehydrated tubing.

Install refrigeration piping per local codes and ASHRAE guidelines.
