Suction pressure setting: Cut out=10 psig; Cut in=25 psig; Differential=15 psig
Head pressure setting: Cut out=230 psig; Cut in=150 psig; Differential=80 psig
It may need to adjust the setting in the field to get the right cycle time.

6. Water Piping
If a water pump is used, install it before the water inlet so that the condenser
cooling water is fed from the discharge side of the pump.

7. Piping, Checking and Testing
NOTES:
• The line connection sizes of liquid filter & indicator, the valve
connection sizes of condensing unit and the line connection sizes of
evaporator unit are not necessary the same as the listed refrigeration
line sizes.
• If the condensing unit is installed above the evaporator unit, use the
suction line one listed size smaller.
• Expansion and solenoid valves have been installed on the liquid line.
1) The installation order starts from condensing unit (including receiver and
discharge valve), liquid line filter-drier, moisture-liquid indicator, liquid line, to
evaporator unit (including liquid line connection, solenoid valve, expansion
valve, and suction line connection), returning to insulated suction line, suction
valve and then back to condensing unit.
2) If the condensing unit is located below the evaporator unit, use inverted U
trap to prevent liquid from flooding back to the compressor; if the elevation
