2. Setup and Installation

2.1 Battery Installation

The device requires 3 AA batteries (included). Open the battery compartment on the back of the gauge and insert the batteries, ensuring correct polarity. Close the compartment securely.

2.2 Attaching Adapters

Select the appropriate adapter (1/4'' male, 1/4'' female, or bent connector) that matches your refrigeration system's port. Carefully thread the adapter onto the gauge's NPT connection. It is recommended to use Teflon tape on the threads to ensure a tight and sealed connection. Use a wrench for installation and removal to prevent damage to the casing.
