8.
Do not paint the sensor
(see Figure 1-8
). Paint fumes block the sensor’s breathing
hole. Blocking this opening damages the sensor permanently, thus voiding the
warranty.

9.
Do not use hydrocarbon-based volatile compounds near the sensor; do not clean
the sensor with any solvent or other products
(see Figure 1-8). The volatile fumes
of these compounds can deteriorate sensor performances. Products to avoid
include: paint, liquid Teflon, close vehicle exhaust, spray can, black pitch, thinner,
RTV (Room Temperature Vulcanization; silicon-based mastic) and solvent.
10.
Do not use galvanized fittings to install the sensor
. Galvanized fittings (pipes,
reducing bushing, rings, etc.) may react with the oil, consequently resulting in
higher readings of gas level. Similarly, do not use galvanized fittings on
transformer valves used for oil sampling.
11.
Do not separate the Hydran M2-X
’s from their respective sensor
. The Hydran M2-X
is set at the factory for a specific sensor. To verify if the sensor and Hydran M2-X
are paired correctly, consult the serial numbers indicated on the shipping box
and/or the Test Certificate and Data Sheet (for an example, see Figure 3-12). The
sensor’s serial number
is located below the sensor connector (see Figure 2-7); the
Hydran M2-X
’s serial number is located on its back (external side of the heate
r
plate).
Turn off the electric power at the fuse box or
service panel before making any electrical
connections, and ensure a proper ground connection
is made before connecting line voltage. Failure to do
