Service Procedures For Safety; Safety Information - Dometic RO400 Service Manual

To prevent personal injury and/or damage to property, it is important to follow sound procedures when carrying out servicing
work. The list below does not attempt to set out all such procedures, but gives some examples.
• Do not attempt to repair the water purifier if you are uncertain of your ability to complete the job in a safe and satisfactory man-
ner.
• Before doing any servicing work or moving the water purifier:
-
Remove the electrical plug from its socket, or switch off the electrical supply to the whole building, or remove the correct
fuse for the electrical circuit to which the product is connected.
-
Turn off the supply of water to the product.
• Never do anything which could impair the proper functioning of any safety device or feature.
• Use only those spare parts which the spare parts catalogue specifies as suitable for the purpose. Substitute spare parts can result
in the safety standards being breached.
• Earthing: The standard colour for earth wires, needed for safety, is green with yellow stripes. Earth wires must not be used as
conductors. It is very important that the service engineer should reconnect all earth connections before completing the servicing
work. Any failure to do so is potentially hazardous.
Read these instructions before installing or servicing. Study the safety precautions and be aware of possible safety hazards
when seeing alert symbols on the water purifier as well as in this instruction. The installation and servicing must be per-
formed according to these instructions and servicing by service personnel only.
installatiOn
• Check that the inlet water to the water purifier fulfills the
requirements, see "
TEchNIcAl fAcTS"
• The water purifier should be connected to an earthed electri-
cal supply. As some operations require the power supply to
be temporarily interrupted, it is best to connect using a plug
that is also easily accessible after installation. Permanent wir-
ing to the electrical supply may only be carried out by a quali-
fied electrician and should be performed with a safety switch.
Incorrect installation can result in personal injury and/or dam-
age to property which are not covered by any warranty.
• Plumbing work should be performed by a qualified plumber.
If you do the installation yourself, you must acquaint yourself
with the applicable standards (e.g. EN1717) and adhere to
them.
• A hose for feed water is supplied with the water purifier.
This hose should be used and any old hose-set should not be
reused.
• It is important for the purifier to be installed upright on a
horizontal surface that can take the load, and that hoses and
cables are neither tensioned nor get jammed when moving the
purifier, e.g. during installation and cleaning.

.
• If the feed water is classed as unfit, have the purified water
checked after installation. After this, test the purified water
once a year or if there is any change in the taste or odour.
Do not drink/use the water if the results are unsatisfactory.
contact your dealer.
• When the water purifier is new, the purified water may not be
used until flushing and calibration have been completed.
• Calibration of the water purifier may only be carried out:
- The first time the water purifier is taken into use.
- If the inlet water quality changes (e.g. when moving).
- After replacing the membrane.
- After exchanging the water quality sensor or printed circuit
board.
• The reverse osmosis technique reduces most substances
extremely effectively. for this reason, the content of those
substances that normally protect pipes, tanks, valves, etc.,
are very low in the purified water from the water purifier.
consider the risk of corrosion and elution when chosing
materials in peripheral equipment in contact with the purified
water.
