Hydran* M2-X Installation Guide
Location #A: Cooling Return
Some transformers may have a valve that is on the pipe that joins the
bottom of the cooling system to the transformer main tank. This location offers
an excellent circulation of oil. It allows for easy access for installation and
taking oil samples directly from the Hydran M2-X.
Note: If a pump is part of the cooling system, it is recommended that the Hydran
M2-X be installed on the discharge side of the pump.
Location #B Drain Valve
All transformers are equipped with a drain valve. This location allows for
easy access for installation and taking oil samples directly from the Hydran M2-
X. Oil flow is reduced compared to the other locations and over time there can
be a buildup of sludge which can further impede the oil flow.
Note: A minimum distance of 12 in. between the ground and the valve is required
so that the Hydran enclosure and cables can be properly installed.
Location #C: Main Tank
Some transformers are equipped with a valve that is mounted towards the
middle portion of the transformer main tank. This location offers good oil
