Connect all electrical components using the wiring diagrams in accordance with
all state and local codes.
9. Evacuating, Charging and Starting the system
CAUTION:
• Always use the superheat and subcooling, pressure readings to charge
refrigerant properly; the listed charge amounts are used for reference
only.
1) Evacuate the system; both discharge and suction valves must be in the
middle positions during evacuating.
2) Charge the system through both suction and discharge valves with refrigerant
using the recommended initial amount; both discharge and suction valves
must be in the middle positions during charging.
3) Turn on the water valve.
4) Turn on the power to start the system and check the following temperatures
and pressures.
10. Adjusting and Completing the installation
1) Set the water regulating valve opening set-point at refrigerant pressure of 120
PSIG. Turn counterclockwise to raise the operating set-point.
