Slide the new rotating seal onto the shaft, ensuring the spring clips seat perfectly.
If voltages are correct but the valve stays stationary, debris may be wedged in the slide track. This requires opening the compressor housing for physical inspection.
Unload solenoid stuck open or failed; Debris blocking oil return channels; Weak internal return spring.

Without it, you risk:
: Prior to any internal service, follow a standard pumpdown procedure to reach a suction pressure of approximately 20 psig (138 kPa) . This avoids refrigerant overcharging or undercharging and is necessary before breaking into refrigeration or oil systems.
Clean or replace solenoid valve; Flush internal oil bypass lines; Inspect slide valve assembly.
The HSA screw compressor, when respected and serviced according to its manual, will deliver thirty years of reliable cooling. Ignore the manual, and you’ll be buying a replacement chiller within two seasons. Slide the new rotating seal onto the shaft,
For specialized repairs, technicians often refer to the HS-3100 Series Manual for detailed wiring diagrams and exploded component views.
Check expansion valve operation immediately; ensure the suction gas has sufficient superheat to prevent liquid carryover.
