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.

20 Table 16 — Capacity Control Reduction Steps *T wo contro lled c ylinde rs (to 33 1 / 3 %) available on request for 5F30. Principle of Operation of the System — An i ncrease in s uc- tion gas pressure, which requires increased compressor capacity , ca uses the needle valve to close.

Capacity Contr ol V alve: Function is to raise or lower the control oil pressure to the hydraulic relay piston in response to refrigerant suction pressure.

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.

32 Contr ol Pre ssurestat f or Booster Applica- tion — The standard dual pressure switch furnished with the 5F ,H compressor cannot be used for booster application. Replace it w ith an appropriate low temperature dual pressurestat that can operate at val ues shown in T able 24.
33 Dischar g e V alve Sprin gs — When 5H compre ssors are used for booster applications where di scharge pressure i s below 10 psig, the standard dischar ge valve springs furnished with the machine should be replace d with an equal number of lighter weight springs, Part Number 5H41-1801.
