Wine Cellar Refrigeration Technical Update – New LRC Expansion Valve Saves Time and Effort

Installation Suggestion

Installation Suggestion for Wine Cellar Refrigeration ComponentAdd a T with an access shrader to the suction line at the coil. This allows pressure measurement at both the coil and condensing. This will save time and effort when you’re troubleshooting or performing maintenance on the system.

Adjustment Recommendations

Note: The expansion valve inside looks almost like a pressure regulator.

  • Use a 3/8” nut driver or socket.
  • To increase pressure turn CLOCKWISE.
  • To decrease pressure turn COUNTER-CLOCKWISE.
  • Always make small adjustments.
  • 1 turn is approximately 6 lbs. of change.
  • Never turn all the way in. This will damage the diaphragm and cannot be undone. This valve will need to be replaced and the warranty will be voided. So be very careful to avoid this.
