Preparing The Water Purifier For Storage; And Protecting It Against Freezing - Dometic RO 400 User Instructions

MAINTENANCE
Preparing the water purifier for storage and protect-
ing it from freezing
The water purifier should be put into storage if:
- it is to be disconnected from water and electricity for an extended
period (1 week or more).
- it is not going to be used for a period longer than four months.
You can choose between two ways of mixing the storage fluid
depending on the desired protection against freezing:
- 2 litres of storage fluid + 4 litres of water provide protection against
freezing down to –15°C.
- 3 litres of storage fluid + 3 litres of water provide protection against
freezing down to –30°C.
The correct product ("Preservative and Antifreeze Liquid") can be
ordered from your dealer (see"Consumables and accessories ").
This product must be kept out of the reach of children.
1 Close the valve on the water supply pipe. Disconnect the
electrical plug and the hose for feed water. See Fig. A.
2 Undo both filter containers as described under "Replacing
the filters", steps 3–6. Remove the two filter inserts and
discard them (should not be kept for re-use). Empty the
water from the containers.
3 Reinstall the empty filter containers back in their normal
places. Make sure that each sealing ring is in place in the
groove on the top edge of each container.
4 Mix the "Preservative and Antifreeze Liquid" with water in
a bucket, dosage, see above.
5 Put the end of the hose (feed water) into the mixture.
Make sure that the end of the feed water hose remains
beneath the surface throughout, see Fig. B.
6 Connect the electrical plug again. The water purifier will
now automatically pump the mixture inside the appliance.
After 40 seconds, disconnect the electrical plug. Repeat
this step until all the mixture has been drawn up.
Disconnect the electrical plug. Leave the tap open and dis-
connect the inlet hose and the pure water hose from the
water purifier. Disconnect the pure water hose by pressing
in the grey ring on the connection and pulling out the
hose, see fig. C.
You have now prepared the water purifier for storage. It can be
left in this state for up to nine months.
When the water purifier is to be brought back into use
you must:
• stand it somewhere where the temperature is above +5 °C
for at least 48 hours.
• Work through all the steps of the full "Flushing proce-
dure", to remove the preservative.
• Install new filters I and II, see "Replacing the filters".
