7 Coolant specification
The quality of the coolant has a considerable effect on the efficiency and useful life of
the cooling system. The following instructions are designed to provide the best
servicing in terms of frost and corrosion protection.
– Always use clean, soft water.
– To avoid frost and corrosion damage use an ethylene-glycol based anti-freeze
mixture. Use a standard anti-freeze with a pH value of 7.0 – 8.5.
– Make sure the mixture ratio is correct when using an anit-freeze. The frost
protection level must satisfy the above standard.
The manufacturer cannot be held liable for frost or corrosion damage caused by
incorrect procedures.
F
The anti-freeze contains ethylene-glycol and other poisonous substances. Ingression
into the human body can result if large quantities come into contact with the skin for
long or repeated periods.
