INSTALLATION MANUAL
VALIDATION OF INSTALLATION
General
The validation procedures described in this chapter do not claim to be complete. The cor-
rect execution and compliance with all given system limitations and interface descriptions
as well as with standards and norms given by authorities must be proven by the aircraft
manufacturer.
Coolant
temperature
The maximum coolant temperature must be determined in order to check the efficiency of
the cooling system.
Figure 8.10: Coolant temperature sensor

Coolant temperature sensor
The coolant temperature is measured using a temperature sensor (1), which is installed
on cylinder 4.
ATTENTION
It is possible to record a false measurement when measuring fluid temperatures.
If fluid volume is lost and sensor is not fully submerged in the liquid, the indicat-
ing instrument could incorrectly display a lower temperature, by measuring the
air temperature instead of the coolant temperature.
Cylinder wall
temperature
Max. permitted cylinder wall temperature on hottest cylinder is 200 °C (392 °F). See the
following figure.

NO
OT
TE

If this temperature is exceeded, appropriate measures (e.g. cooling air ducts,
modifications to cowling, etc.) must be taken to bring it within limits again.
