Workplace Safety; Guidelines For The Handling The Refrigerants And User Safety - TEXA KONFORT 744 Technical Manual

• Make sure you use the correct refrigerant for the vehicle you are working on.
• Connect the hoses correctly by following the colours indicated: Blue hose - LP
connection, red hose - HP connection.
• Make sure all the valves are closed before connecting the device to the A/C
system or to an external cylinder.
• It is absolutely forbidden to modify the calibration of the safety valves and the
control systems.
• Do not smoke near the device or during the operating phases.
• Do not use the equipment near open flames, sparks, hot surfaces: the refrigerant
decomposes at high temperatures, letting off toxic chemical substances that may
cause fires or explosions.
• Do not expose the device to direct sunlight, rain and bad weather conditions.
• Disconnect the hoses with extreme caution; they may contain refrigerant under
high pressure.
• Do not leave the device connected to the power supply if you do not intend to use
it immediately.
• To move the equipment use the specific handles only and balance the station on
its wheels.
• If storing the device for a long period of time, disconnect it from the power mains
and put it in a safe place, where it is not exposed to outside weather conditions.

2.5 Workplace Safety

The device is designed to work at a maximum altitude of 1000 m above sea
level, with an operating temperature between 10°C and 50 °C and a maximum
humidity of 50% at 50 °C.
Safety measures:
• Never, under any circumstance, use the device in an environment where there is
risk of an explosion.
• Only use the device in open or well-ventilated environments (at least 4 air
changes per hour).
• Make sure the workplace is well-lit (average operating illuminance, for mechanic
workshops and assembly on work benches for precision work, is 500-750-1000
lux).

2.6 Guidelines for the handling the refrigerants and user safety

The equipment has been designed and built to operate with R744 (carbon
dioxide, CO2) refrigerant only.
Safety measures:
• Do not transport the equipment with the external tank installed.
• The cylinders must be perfectly clean and clearly labelled in order to identify the
refrigerant contained within.
• Use tanks with pickup pumps only.
