for any damages caused by failure to observe these instructions.
• Do not use the appliance until it has been correctly installed and unless it is in perfect working order.
• The appliance is only suitable for domestic use and similar applications inside closed, frost-free rooms, and must only be used to
heat incoming water from mains supply. It is not allowed to be used with preheated water.
• The appliance must never be exposed to frost.
• The appliance must be earthed at all times.
• The minimal specific water resistance must not fall below the value stated on the label.
• The maximum water pressure must not exceed the value on the label.
• Before commissioning for the first time and each time the appliance is emptied (e.g. due to work on the plumbing system, if there
is a risk of freezing or in case of maintenance), the appliance must be vented correctly in accordance with the instructions in this
manual.
• Do not remove the front cover under any circumstances before switching off the mains electrical supply to the unit.
• Never make technical modifications, either to the appliance itself or the electrical leads and water pipes.
• Pay attention to the fact that water temperatures in excess of approx. 43 °C are perceived as hot, especially by children, and may
cause a feeling of burning. Please note that the fittings and taps may be very hot when the appliance has been in use for some time.
• In case of malfunction, disconnect the fuses immediately. In case of leaks, cut off the cold water supply instantly. Repairs must only
be carried out by the customer service department or an authorised professional.

5. Description of appliance
The instantaneous water heater DCX is a microprocessor-controlled, pressure-resistant
water heater for a decentralised water supply to one or more taps.
As soon as you open the hot water tap,the instantaneous water heater switches
on automatically. When the tap is closed, the appliance automatically switches
off.
Its electronic control regulates the power consumption automatically depending on the
feed temperature and the flow rate, thus reaching the set outlet temperature up to the
appliance’s power limit.
It is also possible to define the outlet temperature by mixing the hot water (55°C) from
the instantaneous water heater with cold water by the tap. However, energy and water
will be saved when selecting the relative temperature to be used on the display of the
instantaneous water heater, without mixing cold water from the tap.
In case of a low feed temperature and a high flow rate at the same time, it could hap-
pen that the pre-set outlet temperature is not reached which is due to the fact that the
appliance exceeded its capacity. The outlet temperature can be raised by reducing the
water flow at the tap.
It is possible to use the instantaneous water heater in combination with an external load
shedding relay for electronically controlled instantaneous water heaters or a prepared
load shedding box to operate the appliance along with an electro-mechanic cooker (re-
fer to installing instructions). We recommend our heaters DEX and DSX as these heaters
have a special operation mode for load shedding relays.

Installing the wall bracket
If you install the instantaneous water heater DCX instead of a conventional instantane-
ous water heater, there is generally no need to drill holes for the wall holder. In this case,
you only need to screw in the double nipples (16) as described in 2. and to secure the
wall bracket.
1. Thoroughly rinse the water supply pipes before installation to remove soiling
from the pipes.
2. Using a 12 mm hexagon socket screw key, screw the screw-in nipples into the wall
connections. After tightening, the double nipples must protrude by 12 mm.
3. Hold the included mounting template on the wall and align it so that the holes in
the template fit over the connections. Mark the drill holes according to the template
and drill them using a 6 mm drill. Insert the included dowels and screw in the wall
bracket.
4. Offset tiling or uneven surfaces can be compensated by up to 30 mm with the aid of
the spacers supplied. The spacers are fitted between the wall and wall bracket.

4. Screw the plastic knurled nut onto the threaded rod of the wall bracket.
5. Open the water supply line to the unit and slowly open the shut-off valve (13c) in the
cold water connection piece (13) (Pos.I). Check all connections for leaks.
6. Next, open and close the hot water tapping valve several times until no more air
emerges from the line and all air has been eliminated from the instantaneous water
heater.
For direct connection, the two 1/2“
screw-in nipples (16) and the 1/2“ seals
must be screwed into the 1/2“ union nuts
of the hot-water (1) and cold-water (13)
connectors. The two 1/2“ caps of the side
outlets of the hot-water and cold-water
connectors must be removed and screwed
onto the open end of the screw-in nipples.
The hot-water and cold-water connectors
must then be screwed into the 3/8“ union
nut of the appliance and delivery pipe,
together with the 3/8“ seals.
For direct connection, it is advisable to
mount the appliance at a distance as illus-
trated alongside, using the spacer sleeves
supplied. It should therefore be noted that
the two fixing holes near the lower pipe
connections are also used.
The flared end of the pipes must be
screwed into the 1/2“ side outlets of the
hot-water and cold-water connectors
with 1/2“ union nuts and 1/2“ seals. The
holes required for the pipes must then be
broken out of the housing with the aid of
a blunt implement.
In case of direct connection please
note: Put the strainer into the cold
water connection!

• To protect the appliance, a fuse element must be fitted with a tripping current com-
mensurate with the nominal current of the appliance.
Load shedding box / relay
If further three-phase appliances are connected, we recommend the use of CLAGE’s
prepared load shedding box (art. no. 82260).Alternatively, a load shedding relay (CLAGE
art. no. 82250) can be connected to phase conductor L2.
Depending on local conditions a jitter of the load shedding relay might appear caused
by low power consumption of the instantaneous hot water heater (low temperature set
point or low water flow rate). In this case it has to be set a higher water temperature or
higher water flow rate.
We recommend our heaters DEX and DSX as these heaters have a special operation
mode for load shedding relays.
