Stay Fresh Standard Freeze Dryers offer customizable configurations to suit different user needs. When purchasing a Standard Freeze Dryer with an industrial pump, you have the option to choose between:

If you originally selected the Steel Wire Reinforced PVC Hose but later decided to upgrade to the Stainless Steel Vacuum Hose, you can do so following the steps below.

To proceed with this upgrade, you will need to purchase a Stainless Steel Vacuum Hose and a Clamp from Stay Fresh, and Contact us to exchange the motorized ball valve assembly.

Step-by-Step Installation Guide

1. Remove the Top Panel
   • Unscrew six screws on top and two on each side (ten screws in total).
   • Carefully lift off the top panel.
2. Remove the Original Motorized Valve Assembly

   • Release the KF25 clamp to detach the barb fitting and motorized valve.
