Please, draw attention of your children that they must not play with the EWH. The EWH Is not designed
to be operated by people (including children) with physical, tactile or mental disorders, as well as
people who cannot use the EWH, unless it is made under control and according to the Instructions of
people responsible for the EWH security.
The EWH Is Installed on the wall vertically according to the shower nozzle or drain length as well as the
attaching point of the shower nozzle supporting arm. Possible variants of the EWH Installation are
given in Fig. 1. During Installation the EWH must be installed In such a way that the water spray doesn't
ingress its housing.
In order to connect the EWH of the models TIP 500 and TIP 700 to the power supply network it Is
necessary to put down the upper cover of the water heater and connect the conductive electric cable
(not Included into delivery) to the terminal block on the EWH housing as follows: connect the yellow-
green cable wire to the terminal E «earth», the blue cable wire to the terminal N «null», the brown (white,
black) cable wire to the terminal L «phase».
For connection we recommend to use a three-core cable with sectional area of each core not less than
2
4 mm . Before starting the electric wiring Installation It Is necessary to cut off power from the power
supply net to which the EWH Is connected. Firstly, the cable Is connected to the EWH and then to the
switch. In order to disconnect the EWH from the power supply net one should use a two-pole switch (not
Included into delivery) with plug fuse, with gap between the disengaged contacts not less than 3 mm at
all poles, 30 A for TIP 500 and 40 A for TIP 700. Before putting the EWH Into operation It Is necessary to
fix the cover. The EWH model TIP 350 has an integrated plugged cable. In order to connect the given
model to the power supply net it is enough to put the cable plug into the socket, which must have an
earth connector. The socket must be located in the place without water ingress. The electric wiring,
security and switchgears must stand current load not less than 30 A for TIP 500, not less than 40 A for
TIP 700 and not less than 20 A for TIP 350. Before the EWH connection to the power supply net fill it with
water.
Operation
Switch on the EWH power supply inserting the power cord plug into the socket or switching on the
multipolar switch. Softly turn the cold water supply tap handle. Press the network switch button on the
front plate. In this case the light indication of the network switch button will switch on. Wait for 15-20 sec
until the outlet water temperature becomes stable. If the EWH outlet water is very cold, reduce the
water supply, if very hot – it is necessary to increase the water supply. The cold tap water temperature
may alternate significantly within the year from 5°C to 20°C. It means that at the same EWH outlet water
temperature the water flow in winter will be less than in summer. The shower spraying mode can be
regulated by turning the handle to the position «winter» or «summer» (for shower nozzles with
automated switch) or by installation of removable rings (for shower nozzles with removable rings). The
water spraying mode has a huge impact on the shower operation. The shower handle position «winter»
(or reduction of the rings number with openings) provides effective water spraying at a smaller volume.
The two-button EWH models have different power modes. For TIP 500 the left button stands for the
2,0 kW mode; the right – for 3,0 kW, totally – for 5,0 kW. For TIP 700 both buttons separately correspond
to 3,5 kW, totally – to 7 kW. The user may choose any suitable power mode.
