Risk of injury to skin and eyes
suffering scalding from contact with
hot coolant spray. Risk of poisoning
from 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 bottles.
Wear protective gloves, protective clothing
and eye protection.

Risk of explosion from welding or
soldering work on closed air
conditioning system. Risk of
poisoning. Inhaling overheated
refrigerant vapors may be toxic. Risk
of injury from skin and eye contact
with liquid refrigerant.Do not carry out any welding work on the
closed air conditioning system or in the
surrounding area. No smoking or open
flames. Wear eye protection and protective
gloves. Work only in well ventilated areas.
