Circuit Leak-Tightness; Vacuum Purging - Tecumseh CAJ Serie Instrucciones De Instalación

The electrical connections will be carried out before the refrigerating system is loaded with refrigerant.
To preserve the quality of the Tecumseh compressor, the safety of the installation and to ensure correct operation and function, it is
essential that the following is observed:
- Always wire the compressor when it is disconnected from the main voltage.
- Check the compatibility of the supply voltage for the installation with the supply voltage for the compressor (see serial label).
- Check the compatibility of the electrical diagram for the compressor with the electrical diagram of the installation.
- Dimension the connection cables (power, control) according to the characteristics of the installed compressor (see serial label).
- Protect the electrical power supply line and install a grounding cable.
- Perform the electrical connections in accordance with the regulations in force in the country of installation.
- Use the electrical components supplied with the compressor, even if other references appear to be satisfactory.
The electrical box is always installed vertically.

5.10. Circuit leak-tightness

Prior to loading the refrigerant, perform a systematic search for leaks at all connections and repair if necessary.
5.11.

Vacuum purging

Vacuum purge the installation in order to achieve a residual pressure of around 200 micrometers of mercury (0.27 mbar),
guaranteeing a good vacuum quality. It is advisable to vacuum purge the HP and LP circuits at the same time, in order to reduce the
operating time and to ensure a vacuum level which is identical throughout the entire circuit.
6. Loading with refrigerant, connection to power for the first time and maintenance:
If the operations described below are carried out in potentially explosive atmospheres, Tecumseh recommends reference to
standard EN 378. Part 4 provides general safety advice and Annex E gives guidelines on performing work on equipment which uses
inflammable refrigerant fluids.
General recommendations:
Electrical boxes must be correctly installed and closed again prior to loading the refrigerant and before connecting the installation to
the main power supply.
