POWER LEAD TERMINAL STLFD — Disassemble only if leaking refrigerant or if resistance to ground is low. If there‘is a short to ground, replace complete terminal plate assembly. Disassembly 1. Unscrew terminal, terminal locknut, and terminal bolt assembly hex nut. 2. Push terminal bolt thru terminal p...

# RINGS 1. Check ring gap* by inserting each ring separately in cylinder approximately 3/8 in. from top. Ring gap should be between .002 in. and .007 in. 2. Install compression ring in top piston groove with side marked “Top” toward piston head. Install oil ring below compression ring with notched e...

An 06ER compressor is standard equipment for low temperature (R-507/404A) applications. For medium temperature (R-134a) applications, an 06EM compressor isstandard. Factory substitutio...

9 SERVICE Protection Devices HIGH-PRESSURE SWITCH — Check by throttling con- denser water or blocking airflow on air-cooled units, allowinghead pressure to rise gradually. Check discharge pressureconstantly throughout procedure. Compressor should shut offwithin 10 psi of values shown in Table 4.LOW-...

10 To Regulate Control Set Point — Turn adjustment nutclockwise to its bottom stop. In this position, set point is86 psig. Control set point is then regulated to desired pressureby turning adjustment nut counterclockwise. Each full turndecreases set point by approximately 7.2 psi. Approximately12 tu...

13 Table 6 — Torque Values Lubrication System TESTING OIL PUMP — An oil pressure tap is located aboveoil pump cover plate (Fig. 12). Oil pressure should be 12 to18 psi above suction pressure.Oil Filter Screen — Screen is accessible through bottom coverplate. Remove and inspect strainer for holes and...

14 Cylinder Heads (See Fig. 11) — Disassemble cyl- inder heads by removing cap screws, and prying up on sidelifting tabs to break heads loose from valve plates. Do not hitcylinder heads to break loose. Check heads for warping, cracks and damage to gasket surfaces. When replacing cylinder head, torqu...
