NOTE: Qualitrol recommends a minimum size of 1" for the transformer oil supply valve and a minimum of 3" vertical
clearance between the valve centerline and the transformer foundation for proper installation space.
Ensure the following prior to mounting the monitor:

An adequate valve location for mounting the DGA‐LT1 monitor has been identified

Transformer is oil‐filled and a baseline Dissolved Gas Analyzer sample has been taken to provide
baseline levels for Hydrogen concentration and Oxygen concentration for use in configuration of the
system

All shipped items have been located
The following tools are required for installation of the DGA‐LT1 monitor:

Adjustable wrench and/or pipe wrench

Teflon tape and pipe‐thread sealant

Container to collect oil during installation
Note that installation of the sensors and gateway should take place from transformer closest to the cellular
gateway location outwards to ensure that a communication path has been established for commissioning of
each sensor.
