4.2.2 VA-2 Installation
Note: To prevent leaks, use tape and grease on all NPT threads. Starting from the
bottom, wrap the tape in the opposite direction as the threads so that when attaching,
the tape is not torn off. Once taped, apply enough grease to cover the threads.
1. Ensure that the drain valve and top/fill valve are properly shut and that there is not
excessive oil leakage or obstructions to prevent installation.
2. If you need to preserve the ability to use this drain valve to sample oil directly from the
transformer, install a stainless steel
tee and another valve with plug onto the drain valve.
