PROTECTION AGAINST FROST
As a precautionary measure when frost is first anticipated, drain the pump-volute casing by tipping
the whole unit towards the suction-end, or remove the drain plug situated at the base of the volute
casing. Then open the drain valve located on the volute.
Use an anti-freeze solution in the engine coolant system in the correct proportions stated for the
particular brand recommended.
As the engine is constructed of aluminium alloy, it is essential that the anti-freeze solution is of the
type suitable for use with this material.
If no anti-freeze is available, it will be necessary to drain the engine.
Always drain the cooling system while the engine is WARM.
IMPORTANT:
NEVER attempt to run the engine without water.
Note:
After draining, attach a ‘WATER DRAINED’ notice to warn others that the system must
be refilled before restarting the engine.
