Hydran* 201i Instruction Manual
7. Do not use a pipe wrench or chain wrench to install the sensor. Doing so may
cause serious damage to the sensor, thus voiding the warranty.
It is
recommended to use General Electric's Hydran 201TW tube wrench (see Figure
6-4 below) to correctly install the Hydran 201 sensor. One Hydran 201TW tube
wrench per site is recommended.
