4. DESCRIPTION AND OPERATING PRINCIPLE
Water is heated immediately, when flowing through the copper cylinder. All
heating elements are placed inside the copper cylinder (Figure 4).
Figure 4: 1- cold water inlet; 2 - hot water outlet; 3 – fixation holes; 4 – heat
protector; 5 - copper cylinder with heating elements; 6 - connecting block;7 -
pressure-sensing device; 8 - cable clamp; 9 - switch.
The temperature adjustment in the outlet is performed by the regulation of its
flow.
On the diagram (Figure 3) the dependence between the temperature
difference in the inlet and outlet and the volume of water flow is shown.
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 in
winter will be less than in summer. For the optimal flow, there are two shower
spraying modes. One mode is designed for using EWH in winter, another – in
summer.
After the water was supplied to EWH and the minimum allowable pressure
(0.05MPa) was set, pressure sensor will automatically switch on thermoelectric
heating elements, which will be indicated by the light of the power-on button. If
the water pressure in the inlet becomes lower than minimally allowable, pressure
sensor will automatically switch off the heating elements, the lights will go out,
the heating will stop.
Another security device is the heat protector, installed on the copper cylinder.
It disconnects EWH from the power grid in case of the water overheat (which is
not considered as the defect). After water cooling EWH will be automatically
switched on.

5. SAFETY RULES
Power cords, safety valves and switching systems must correspond to the
capacity of the EWH.
Children should not be allowed to play with 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.
GROUND CONNECTION OF THE WATER HEATER IS
NECESSARY!!
DO NOT:
-leave the plugged in EWH unattended;
-switch EWH, before installing it on the wall vertically and filling it with
water;
-plug the appliance In and out with wet hands;
-use the spare parts, which were not recommended by the water heater
manufacturer;
-use water with impurities : sand, corrosion, sludge;
-close the EWH hot water discharge and connect to it to any kinds of
isolation valves;
-switch EWH with the frozen water inside.
6. INSTALLATION AND OPERATION RULES
Installation works must be performed by qualified specialists.
During installation the following sequence of actions is recommended:
а) Wall mounting of the water heater;
b) Connection to the water mainline;
c) Connection to the electric grid.
6.1. Wall Mounting
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 Figure 1.
During installation the EWH must be installed in such a way that the water
spray doesn’t ingress its housing.

Put EWH on the wall using 2 screws (not included into set). Before putting on
the wall:
-put down the upper cover of EWH (loosen the screws on the sideboards);
-mark hole locations on the back cover, do the holes in the wall and fix the
EWH bottom in-place. Install the upper cover afterwards.
6.2. Connection to the water mainline
Connection diagram is given in Figure 2.
Figure 2: 1 – water heater (EWH); 2- cold water inlet pipe; 3- hot water outlet
pipe; 4 – spout; 5 – adapter; 6 – hose; 7 – shower nozzle; 8- cut-off valve; 9-
cold water main; 10 – shower nozzle bracket; 11- flow controller (tap).
Hook up the flow controller (11) (not included into set), which ensures the
smooth adjustment of water supply, to the cold water inlet (2) – left pipe of
EWH marked “Inlet”. Connect the flow controller (11) to the cold water inlet (2),
using the copper pipe with 10-15 mm diameter or flexible connector. For to
ensure long life of the water heater, use water purifying filter.
When torqueing connections on the EWH, it is necessary to hold the inlet (2)
and outlet adapters (3) using the crescent wrench in order not to damage the
internal connections of the metal parts of the water heater.
Connect the shower nozzle (7) using long flexible hose (6) or spout (4) with
the hot water outlet (3) – right pipe EWH marked “Outlet”. For to connect to the
hot water outlet (3) both shower nozzle (7) with flexible hose (6) and spout (4) at
the same time use the adapter (5).
When connected, supply water to the EWH (1). Shut down the flow controller
(11) after EWH is filled with water.
It is forbidden to put any isolation valves, which could bar free water
flow, on the outlet.
It is forbidden to use the connecting pipes, which were used previously.
6.3. Connection to the electric grid.
In order to connect the EWH of the models THERMEX 500 STREAM and
THERMEX 700 STREAM to the electric grid it is necessary to put down the
upper cover of the water heater and connect the conductive electric cable to the
terminal block on the EWH housing as follows: (6, Figure 4) according to
electric scheme : L – “phase”, N – “null”, E – “earth”.
For connection we recommend to use a three-core cable (not delivered) with
sectional area of each core not less than 4 mm2 (for models THERMEX 500
STREAM иTHERMEX 700 STREAM). 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 with plug fuse, with gap between the disengaged
contacts not less than 3 mm at all poles, 30A for THERMEX 500 STREAM and
40A for THERMEX 700 STREAM (not included into the delivery set). Before
putting the EWH into operation it is necessary to fix the cover.
The EWH model THERMEX 350 STREAM has an integrated plugged cable.
In order to connect the given model to the electric grid it is enough to put the
cable plug into the socket, which must have an earth connector and bear capacity
of 3.5 KW. If plugged cable of the THERMEX 350 STREAM model is
damaged, on order to avoid the danger, it should be replaced by the manufacturer
or by his agent or by any other qualified person. The socket must be located in
the place without water ingress. The electric wiring, security and switchgears
must stand current load not less than 30A for THERMEX 500 STREAM, not
less than 40A for THERMEX 700 STREAM and not less than 20A for
THERMEX 350 STREAM.
It is forbidden to use water heater without grounding!
7. 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 (11, Figure 2). Press the network
switch button on the front plate. In this case the light indication of the network
switch button will switch on (9, Figure 4).
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 two-button EWH models have different power modes. For THERMEX
500 STREAM the left button stands for the 2.0 kW mode; the right - for 3.0 kW,
totally - for 5.0 kW. For THERMEX 700 STREAM both buttons separately
correspond to 3.5 kW, totally - to 7.0 kW. The user may choose any suitable
power mode.
After use of the EWH turn the water heater off by pressing the network
switch button/buttons. The water heating will stop; the light indicators will go
out. With the cork cut off the cold water supply to the EWH.
If you are not going to use electric water heater in a short term, pull power
cord plug out of the socket (THERMEX 350 STREAM) or switch off the
multipolar switch (THERMEX 500 STREAM, THERMEX 700 STREAM).
8. TECHNICAL MAINTENANCE.
Keep the EWH surface safe from damages, blows und influence of active
solvents.
Wipe the dirty EWH surfaces with soft damp cloth moistured in soapy water. Do
not use here any abrasive or chemically active detergents.
Rub the sprinkle shower and kitchen nozzles from the dirt regularly.
All works for the EWH maintenance must be done after it was disconnected
from the electrical network.
9. UTILIZATION
Provided that the Installation, operation and maintenance rules are observed
and the consumed water quality complies with the current standards, the
manufacturer sets the 3 years service life time of the EWH.
