REVO-E Heat pump 9 Removal/ installation of components
9.10 Suction pressure sensor removal/
installation
There is a valve insert built into the soldering support of
the suction pressure sensor (2, Fig. 909) that automati-
cally closes when the sensor is removed from the support.
9.10.1 Remove the suction pressure sensor
• Loosen electrical connection on the plug.
• Unscrew the sensor, holding the soldering support
with a suitable tool.
9.10.2 Install the suction pressure sensor
• Moisten sealing ring with refrigerator oil.
• Screw on the sensor, holding the soldering support
with a suitable tool.
• Reconnect electrical connection on the plug.
ATTENTION:
The maximum pressure of the leak test is 17 bar,
since otherwise the suction pressure sensor will
become damaged!
9.11 High-pressure sensor removal/
installation
There is a valve insert built into the soldering support of
the high-pressure sensor (1, Fig. 909) that automatically
closes when the sensor is removed from the support.
9.11.1 Remove the high-pressure sensor
• Loosen electrical connection on the plug.
• Unscrew the sensor, holding the soldering support
with a suitable tool.
9.11.2 Install the high-pressure sensor
• Moisten sealing ring with refrigerator oil.
• Screw on the sensor, holding the soldering support
with a suitable tool.
• Reconnect electrical connection on the plug.
ATTENTION:
The maximum pressure of the leak test is 17 bar,
since otherwise the suction pressure sensor will
become damaged
