system. Then blow air through the cooling system to dry it.
If the cooling system cannot be drained because standby capability is required at short
notice, protect the cooling circuit against frost and corrosion damage. To do this, add
suitable additives to the cooling water.
NOTICE
Impairment of the heat transport
Additives such as anti-freeze and corrosive inhibitor can impair the heat transport.
Operate the motor only with the contractually agreed water quality.
For avoidance of deposits, the cooling water circuit must then be kept running. So as to be
certain of excluding the possibility of formation of condensation within the machine, the anti-
condensation heating should also remain switched on (if fitted).
