The pressure switch is factory fitted during manufacturing process and must not be tampered
with, disassembled or removed. Any user interference will void warranty.
Be aware of the danger posed by the protected equipment
.
When working in the vicinity of
electrical equipment observe corresponding safety rules and instructions. Working on
electrical installations may be performed only by qualified persons.
Install the T Series so that the pressure switch is not exposed to aggressive chemical
substances (caustic, acids, solvents, corrosive substances etc.) and in direct influence of
weather conditions.
Always place the pressure switch in the lower part of the risk area to avoid direct flames and
heat.
The pressure switch cannot be in direct contact or be in immediate proximity with parts
which heat to temperatures of more than 80 °C (176 °F).
