Table 2A — 06D Physical Data
*Compressors listed are for R-22 applications. For R-134a and R-507/
404A an 06DR compressor is standard. Factory compressor substitutes
may be made. Contact Carrier Sales Representative.
NOTE: The 06DE8251 compressor unit with the 06DA825 compressor
replaces the 06DE8241 once inventory of the 06DA824 compressor is
depleted.

*Compressor listed is the standard compressor for R-22, air conditioning
duty. An 06DR compressor is standard equipment for low temperature
(R-507/404A) or medium temperature (R-134a) applications. Factory
substitutions may be made. Contact Carrier Sales Representative.
†The condenser listed is for R-22, air conditioning duty and may change
based on the application. Maximum condenser operating pressure:
350 psi refrigerant side, 300 psi water side (“CX” models); 350 psi
refrigerant side, 150 psi water side (“AX” models).
NOTE: The 07DB210 with the 06DA825 compressor replaces the
07DB210 with the 06DA824 once the compressor inventory is depleted.

NOTES:
1. Values for the high- and low-pressure switches based on R-22.
For other refrigerants, reset to pressure corresponding to satura-
tion temperatures indicated by the listed pressures.
2. Values for oil pressure are above operating suction pressure
(pressure differential between suction and discharge pressures
of oil pump).
CAPACITY CONTROL (Suction Cutoff Type)
Control Set Point (Cylinder Load Point) —
Set
point is adjustable from 0 to 86 psig. Pressure differential
between cylinder load-up point and cylinder unload point is
adjustable from 7 to 19 psi.
To Regulate Control Set Point —
Refer to Fig. 7.
Turn adjustment nut clockwise to its bottom stop (with nut in
this position, set point is 86 psig). Control set point is then
regulated to desired pressure by turning adjustment nut coun-
terclockwise. Every full turn decreases set point by 7.2 psi.
Approximately 12 turns in counterclockwise direction will de-
crease control set point to 0 psig. Table 4 shows steps of control
for the compressor and condensing unit.
Pressure Differential Adjustment —
Turn differ-
ential adjusting screw counterclockwise to its back-stop posi-
tion (differential in this position is 7 psi). Pressure differential is
set by turning adjustment screw clockwise. Every full turn
increases differential by 1.2 psi. Approximately 10 turns in
clockwise direction will increase pressure differential to 19 psi.
