Electrical And Plumbing Connections; To Fit The Tap For Purified Water - Dometic RO 400 User Instructions

INSTALLATION

Electrical and plumbing connections

The illustration reproduced in Fig. C is also to be found on
the rear of the appliance, to show how the various connections
should be made.
The water purifier is connected to the cold water supply (tem-
perature range 2-40 °C) via a polyethylene feed hose (3). The
cold water pipe should have a valve easily accessible for shut-
ting off the supply, see Fig. D. If the appliance is being con-
nected to new pipes or pipes which have been out of use for
some time, the water should be allowed to run for a while
before you connect the hose. This will prevent the appliance
intake filter (referred to here as the "grid") from getting
blocked by sand or rust. The appliance has two outward water
hoses. The purified water is taken via the purified water hose
(1) to a separate tap, while the reject water is connected
directly to a waste pipe via the reject water hose (2).
The water purifier must be connected to an earthed electrical
supply (230 V, 50 Hz, 10 A). We recommend use of a plug-in
connection to a wall socket, since certain procedures such as
replacing filters and preparing the appliance for storage if it
will not be used for a time require the power supply to be dis-
connected, then reconnected. Using an electrical plug also
makes it easier to move the appliance.

To fit the tap for purified water

Avoid cutting the hose for purified water, even if it is too
long. If it must be cut, do so with a very sharp knife, such as a
Stanley knife, making sure that the cut is straight and clean,
and that the hose is not deformed by cutting, see Fig. E. It is
important to observe these points to ensure that the connec-
tion will be fully watertight. Install the two hose inserts, one
at each end of the hose for purified water.
1 Mark the centre of the place where the purified
water tap is to be installed. Make sure that there is
enough room below the worktop for the purified
water hose to be attached beneath this point.
2 Drill a 16 mm hole.
3 Remove the small section of protective tubing and
install the main tap pipe on the tap assembly. Install
the whole tap on the worktop/sink bench as shown
in Fig. F1. The worktop or bench must be no
thicker than 35 mm. Screw the quick connector fit-
ting onto the main thread protruding from the bot-
tom of the tap assembly. Then press the end of the
purified water hose all the way home into this quick
connector, as far as the line marked on the hose
(about 17 mm), see Fig. F2.
