3.2. Specifications
The housing of the compressors in the 'AJ' family is subject to the low pressure of the refrigeration system.
In line with the PED and in order to ensure the best level of quality of its products at all times, Tecumseh tests each compressor on an
assembly line at a pneumatic pressure which is greater than or equal to the requirement 1.1 x PS as per Annex C 1.3.2 of standard NF
EN 14276-1, regardless of the refrigerant indicated and based on the calculation of the most restricted refrigerant, R455A.
For information: 1.1 * PS (46°C sat) = 23.7 bar rel for R455A.
Additional explosion tests are also performed periodically.
4. Transport – handling:
Ex-works, the compressor is filled with oil and nitrogen (0.3 to 0.5 bar). It does not contain refrigerant on delivery.
For further information on delivery of the compressors, please see your terms and conditions of sale. Check that the equipment is in
good condition and is free from defects on receipt (correct external appearance, no impact or deformation), in particular on the
connection terminal.
Never handle the compressor by its pipes or tubes, by the Te-Connect or by the power supply cable. Use the plinth provided for this
purpose. See our technical documentation for further information on storage positions and authorized transportation.
The recommendations for the transportation of systems filled with refrigerant fluids are the responsibility of the manufacturer of
these systems.
5. Recommendations associated with the use and installation of a compressor in a refrigeration system:
In the case of operating with flammable fluids, the installation must be designed on the basis of a risk analysis to avoid the
accumulation of refrigerant in the event of leakage in areas that are potential ignition sources.
