Installation
After the installation preparation is completed, the HYDROCAL unit can be installed. The installation
is divided into 3 steps:
Mechanical installation
(2.4.1)
Electrical connection
(2.4.2)
Putting into operation
(2.4.3)
2.4.1.
Mechanical installation
The sequence of the mechanical installation depends on which connection type is available on the
transformer side. There are basically 2 types of mechanical installation:
Direct installation
(2.4.1.1)
Indirect installation
(2.4.1.2)
Note:
In case there are strong vibrations on the connection valve, the valve should be relieved by a
support.
A good oil flux should exist on the installation position. If necessary, use a reduction piece (adapter).
In order to have a sufficient oil flux on the membrane, the diameter of the valve should be not less
than 25 mm. For optimal working conditions, the valve diameter should not be more than 76 mm. The
valve must be on earth potential.
Attention!!!
The distance between the oil main stream and the backplate unit shall not
be more than 6 times the length of valve diameter.
(Distance 150 mm at Valve-
25 mm / Distance 228 mm at Valve-
38 mm /
Distance 300mm at Valve-
50 mm / Distance 450mm at Valve-
76 mm).
