Checking

Danger!

Risk of injury to skin and eyes caused by scalding from contact with hot coolant spray. Risk of poisoning caused by swallowing coolant.

Do not open cooling system unless coolant temperature is below 90°C. Open cap slowly and release the pressure. Do not pour coolant into beverage containers.

Wear protective gloves, protective clothing and safety glasses.

Unscrew cap

5

Set heater switches to maximum heat output

6

Check coolant level

If the antifreeze protection of the coolant is inadequate, either antifreeze must be topped up, or the coolant must be replaced:

Drain coolant, fill.
