Replacing Pressure Controls Without Removing
Refrigerant Charge
This procedure reduces repair time and cost. Use it when
any of the following components require replacement, and
the refrigeration system is operational and leak-free.
• Fan cycle control (air cooled only)
• Water regulating valve (water cooled only)
• High pressure cut-out control
• High side service valve
1. Disconnect power to the ice machine.
2. Follow all manufacturer’s instructions supplied with
the pinch-off tool. Position the pinch-off tool around
the tubing as far from the pressure control as feasible.
Clamp down on the tubing until the pinch-off is
complete.

Warning
Do not unsolder a defective component. Cut it out of the
system. Do not remove the pinch-off tool until the new
component is securely in place.
3. Cut the tubing of the defective component with a
small tubing cutter.
4. Solder the replacement component in place. Allow
the solder joint to cool.
5. Remove the pinch-off tool.
6. Re-round the tubing. The pressure control will operate
normally once the tubing is re-rounded. Tubing may
not re-round 100%.
