8.4 Storage
CAUTION!
Danger of burns from hot surfaces or liquids.
Slight or moderate physical injuries may result.
■
Use appropriate personal protective equipment.
■
Do not touch the drive components or batteries of the DEEP BLUE system
immediately after use.
■
Allow the DEEP BLUE system to cool down before working in the immediate
vicinity.
8.4.1 Long-term storage and winterizing
ADVICE
Water/glycol mixture must not enter the environment, and must be disposed of
separately.
Water cooling
In order to prevent frost damage and corrosion, for long-term storage no sea water
may remain in the components or hoses of the cooling circuits.
The cooling water pump is activated if necessary via the system display, via
Settings
|
Cooling Policy
,
see
Chapter 6.2.7, "Settings"
. Briefly set the parameter to
Imme-
diate
. This manually switches on all cooling pumps.
If there is no water in the system, restrict the running time to five minutes. If possi-
ble, disconnect unaffected pumps from the electrical supply.
Flushing and draining the coolant circuit
ADVICE
The following process must be carried out individually for each coolant circuit.
1. Close all cooling circuit water inlets.
2. Prepare approx. 10 to 20 litres of water/glycol mixture (mix ratio: 1:1) in a con-
tainer.
3. Loosen the cooling water intake inside the boat.
4. Activate the cooling water pump in order to pump remaining sea water out of
the system.
5. Position the collecting container under the cooling water outlet.
6. Pump the glycol mixture through the system via the cooling water supply line,
and collect it at the outlet.
ADVICE
The mixture collected can be used again for this type of flushing process in
other coolant circuits.
7. Allow the pump to run until no more liquid is discharged.
8. After the work is complete, use the system display to set
Cooling Policy
to
Late
,
see
Chapter 6.2.7, "Settings"
.
This prevents the pump from running dry too long and becoming damaged.
9. Open the filter for the sea water pumps.
10. Check the filter for damage, and clean it if necessary.
11. Re-insert the filter for the sea water pumps.
12. Close filter housing again.
Winterizing the electrical system
Comply with the permitted storage temperatures, see
Chapter 3, "Technical data"
.
1. For storage in a warm environment, ensure good ventilation.
