Install steps

  1. Turn off and unplug your freeze dryer.
  2. Pull the back panel and metal shroud off. Unscrew the stainless screws along the bottom and back of the machine. Make sure your vacuum hose can pass freely through the shroud hole; remove the clamp and unscrew the connection point if needed.
  3. Connect the wires to the back of the PLC. There are five wires to connect in total, and all are labeled with the proper connection point on your freeze dryer.
  4. Make sure you are not touching any exposed wires. Plug your freeze dryer back in and turn it on. Carefully scan the QR code on the bottom of the HashyLink using the SoftAP app and complete Wi-Fi setup.
  5. Turn your freeze dryer off and unplug it again. Put the metal shroud and back panels onto your freeze dryer. Make sure all tabs are connected properly before tightening the screws back down.
