2 OPEN-DRIVE COMPRESSORS These compressors are desi gned to operate with Refriger- ants 12, 22, 134a, 502, or 507/404A. See T able 1. Operating Requireme nts — Satis factory op eration of a reciprocatin g compres sor depen ds on 3 fundamental requiremen ts: 1.
3 During compressor shutdown, gr avity , thermal act ion and refrigerant absorption can result in a re frigerant and oil mixture in compressor crankcase. Gr avity flow can be preve nted by the use of recommende d loops, but therm al action a nd t he absorp- tion of refrigerant by lubricating oil cannot be prevented by piping design.
4 Compressor Capacity Notes 1. Compressor capacities are based on 1750 rpm and 15 F subcooling for all unit sizes and refrigera nts. 2. Multiplying factors for other rpm: See Multiplying Factors chart on pa ge 31.

23 Control Pressurestats — Dual pressurestats are furnis hed with all 5F ,H compress ors. They ar e often referre d to as high- and low-pressure cutouts. Their function is to cut the ci rcuit to the holding coil of the compressor motor start er when pressure setting l imits a re exceede d.

25 CAP ACITY CONTROL MODIFICA TIONS F OR HEA T PU M P A PP L I CA T ION — Where 5F40, 5F60, and 5H com- pressors are used in refrigerant cycle r eversing heat pump applications, it is usually necessary to modi fy the standard capacity control arrangement to satisfy unloading requir e- ments.
26 Appli cation Requi ring 50 % Capacit y Reduct ions — This is the usual specification f or heat pump applications and should cover majority of cases.
27 The variety of systems using 5F ,H c ompressors make it impractical to cover all a spects of hot gas bypass operation. The following guidelines will aid in determining the proper application. The hot gas bypass valve is basically a press ure regulating valve installed to hold a constant compressor suct ion pressure.
