INSTALLATION INSTRUCTIONS
• Mark the work area to prevent entry of unqualified people;
• Ensure that the leak detection system used is spark-proof, secured appropriately or inherently safe
• Ensure that all maintenance personnel have been trained.
Wherever possible, the refrigeration system operating with a refrigerant classified as an A2L category will be transported to a workshop authorized
and compliant to do its maintenance.
Check that the pressure of the refrigeration system will not be a danger factor during the intervention (projection of parts, refrigerant etc.). The
compressor can reach temperatures above 120°C in operation. Do not intervene in the compressor without protection.
6.5.1. Recovery of flammable refrigerants
• Use a recovery plant suitable for flammable refrigerants
• Identify the refrigerant in the cylinder and affix the flammability logo
• Do not mix refrigerants together.
6.5.2. Inerting the refrigeration system and precautions before soldering
• Ensure that a fire extinguisher is present nearby,
• Inert the system with nitrogen without oxygen (or air),
• The flow will be ventilated preferably outdoors.
6.5.3. Opening of the refrigeration system and replacement of components
IMPORTANT : Soldering operation is prohibited on installations / refrigeration system charged with a flammable refrigerant . More generally,
it is imperative to prohibit any source of ignition (sparks, flames, hot springs) near the circuit.
After replacing components, crimped connections are an alternative to soldering.
6.5.4. Evacuation
For flammable refrigerants, check that the vacuum pump contactor is the only source of ignition.
Make sure the vacuum pump does not blow near an ignition source (empty pump switch, etc.).
An evacuation outside is recommended.
6.5.5. Replacing electrical components
• The electrical cabinets will be properly closed before refrigerant charging and restarting installation.
• Replace defective electrical components with the same parts as recommended by the manufacturer to ensure continuity of installation safety.
For electrical components of compressors please use Tecumseh's original spare parts.
• Do not move electrical components.
Check regularly
• security and regulatory bodies;
• the states of the electrical and refrigeration connections (retightening, oxidation, etc.);
• the operating conditions;
• the compressor attachments on its support;
• how the oil heater works.
Look for leaks once a year, or according to local regulations.
Signage
The refrigerant used and its mass must be labelled, whatever they may be.
In the case of a fluid classified A2L, the flammability logo will be visible and readable.
6.6. End of life of the product
Fluorinated refrigerants will be recovered as imposed by the F-Gas regulation in the European Union.
Tecumseh also advises recycling the compressor oil and the compressor itself.
7. WARRANTY
For information on the compressor warranty, refer to the terms and conditions of sale.
In order to be able to continuously improve these products, Tecumseh reserves the right to modify these instructions without notice.
