7.5 Information and safety labels on the
product
Danger!
The safety-related labels on the pack-
age/chiller must be followed!
7.5.1 Labelling of the pressure and
temperature sensors, heater
(safety labels)
fig.8: Safety labels of the pressure and temperature sensors,
heater
Importance of the labels:
Before replacing pressure and temperature sensors
without dip tube, it must be ensured that the pipes
into which the sensors are mounted are not pressur-
ised. The pressure-free state can be achieved by
closing the shut-off valves before the sensor to be
replaced.
Before replacing oil heater it must be ensured that
the oil separator into which the oil heater is screwed
in is not pressurised.
Hint!
Not applicable to oil heaters of the
HLP type series.

Importance of the labels:
If any leakage occurs at a screwed connection
(escaping gases or vapours), the screwed connec-

Counter-hold the screwed pipe connection using
a wrench. Tighten the pipe nut about
rotation beyond the point where the increase in
the force if felt.
® The leakage is remedied.
