H - EVERY TWO YEARS (OPTION AIR CONDITIONING)
WARNING: NEVER TRY TO REPAIR ANY ANOMALIES YOURSELF. TO RECHARGE A CIRCUIT, ALWAYS CONTACT YOUR DEALER WHO HAS THE
APPROPRIATE SPARE PARTS, TECHNICAL TRAINING AND NECESSARY TOOLS.
- Do not open the circuit under any circumstances as this would cause the coolant to be lost.
- The cooling circuit contains a gas which can be dangerous under certain conditions. This gas, coolant R 134a, is colourless,
odourless and heavier than air.
• If this gas is inhaled, take the victim into fresh air, give oxygen or artificial respiration if necessary and call a doctor.
• If the gas is in contact with the skin, wash it immediately under running water and remove any contaminated garments.
• If the gas is in contact with the eyes, rinse them in clear water for 15 minutes and call a doctor.
- The charger has an oil level gauge; never unscrew this gauge because it would depressurise the installation. The oil level is only
checked when changing the oil in the circuit.
