DESCRIPTION OF COMPRESSOR FEATURES
The compressor is a reciprocating semi-hermetic type that operates at 1750 rpm to give dependable high
performance operation. The compressor is UL and CSA, approved. Some features include:
Crankcase Pressure Equalizing Tube To equalize crankcase and system pressures quickly on start-
up. This prevents oil from leaving compressor due to high refrigerant concentration which occurs
in crankcase on start-up.
Suction Inlet Strainer Compressor is equipped with a screen located in the suction manifold of the
motor and belt to stop installation scale or abrasives from entering the compressor and shortening
the life of the motor and compressor.
Oversize Suction Gas Passages To give less turbulence and more efficient motor cooling by
suction gas. A cool motor will give more economical operation and longer life.
Lubrication Oil Passages Lubrication is provided by a combination of oil pressure and oil splash.
Passages carry oil to internal bearing and running gear surfaces in large volume at low oil pressure.
Oversize Oil Sump On shutdown, oil is diluted by refrigerant. On start-up, oil level can temporarily
drop too low causing unnecessary wear. Oversize oil sump holds extra oil in crankcase to prevent
normal oil migration from dropping oil level below safe lubrication range.
