Conservation at longer operation interruption
6.9.1 Measures on preparation of the winter storage
1. Rinse raw water circuit with an anti-freeze solution, even if this contains a corrosion protection
means. The raw water inlet must be removed at the water cock. Over a hose connector the
anti-freeze protection mixture is to be sucked in from a container. The leaked cooling water
with the exhaust is to be led back into the sucking in container. The circuit must be kept upright
some minutes to guaranteed that the anti-freeze protection mixture reaches all ranges of the
cooling system.
2. The concentration of the anti-freeze mixture in the internal cooling circuit must be checked
with a suitable measuring instrument. The concentration must be furnished according to the
lowest temperatures which can be expected.
3. Clean raw water filter and check seal.
4. Check water cock for practicability. And spray with a corrosion protection oil from the inside or
lubricate with acidless grease.
5. Check all hoses and hose connectors for good condition. The rubber hoses are very sensitive
to enviromental influences. They can age fast with dry air, in environment of light oil and fuel
steams and increased temperature. The hoses must be checked regularly for elasticity. There
are operating situations, which the hoses must be renewed once in the year.
6. Check the hose connectors at all raw water valves doubly and if possible protect them with
double hose clamps.
7. Dismount the impeller of the cooling water pump and check for wear. The impeller may not
remain in the pump. It must be greased with vaseline and be kept at a dark place. It can be
reintragrated in the spring again into the pump, if it is in good condition. The impeller is a wea-
ring part, it is recommended to renew it always in the spring, independently how many opera-
ting hours the genset ran.
8. Control of the vent valve at the raw water inlet. If the generator is installed below the waterline,
always a vent valve is necessary. The vent valve must be checked also during the season
regularly. In the winter storage the vent valve should always be disassembled, checked and
greased. Hardens or got parts dirty are to be replaced.
9. Check water lock: If the generator were rinsed with an anti-freeze mixture, the antifreeze mix-
ture can leave in the water lock. If the generator were rinsed with fresh water, the water in the
water lock must be drained. Otherwise the danger exists that the collector is blown up and
destroyed by ice.
10.Check the exhaust/water separator on leakage and if the hose connectors at the lower surface
of the separation unit are in normal condition. (with extremely sulfureous fuels it is possible
that also high-grade steel tube ends are attacked.)
11. Check all construction units at the generator inside the sound cover for leakages. If there are
traces of humidity in the sound cover, the cover must be dried. Further the cause for the wet-
ness must be surched and eliminated.
12.During the winter storage the upper section of the sound cover must be taken off, in order to
avoid condensed moisture formation, if traces of humidity remain in the sound cover inside
casing by leakages in the raw water circuit.
