PRODUCT DESCRIPTION
This wall hung electric boiler is available in 7 models,
single or three-phase:
• Models 09 and 15 Mono are supplied with 230 V
(single phase).
• Models 09, 15, 22, 28 and 36 Tri are supplied with
400 V (three phase).
The maximum power can be adjusted by
acting on the terminal bridges.
Casing
The boiler is protected by a steel casing that first
undergoes a degreasing and phosphation process
before being lacquered and burnt at 220°C.
Heating body
The boiler heat exchanger is constructed from STW
22 steel. It is hydraulically tested under a 4.5 bar
pressure (maximum service pressure = 3 bar).
Heating elements
Removable immersed heating elements, construct-
ed from stainless steel Incoloy 800 and mounted
from the top of the heating body, provide the heating
source for the boiler. Refer to
"Replacing the Heating
Elements" on page 26
for more information.
Hydraulic connection
The boiler is suitable for connection to most sealed
heating and hot water systems, with a maximum
working pressure of 3 bar and a maximum tempera-
ture of 87°C.
The boiler is equipped with a primary 10 litre expan-
sion vessel, suitable for a system water content of
up to 160 litres. For systems of a larger capacity, it
may be necessary to install an additional expansion
vessel.
It is also comprised of pressure and temperature
sensors, a safety valve, a low water pressure switch,
control and high limit thermostats, on/off and power
level switches.
A circulating pump is installed at the bottom of the
boiler, on the supply side.
The boiler can be used in cascaded systems, allow-
ing greater outputs to be achieved.
Circulating Pump
The E-Tech W boiler is equipped with a new-genera-
tion high-efficiency pump that can be set up to meet
the system requirements. The pump's LED indica-
tors display the operation mode or the status of the
pump, and a pushbutton allows to access the pump
settings.
Electrical connection
The boiler requires two different power supply sources,
one for the control circuit, and one for the power circuit.
Connection glands for both the main power supply and
optional external controls are provided, suitable for sin-
gle or three phase electrical supply depending on the
required boiler output.
An internal 3 amp Magnetic Circuit Breaker is provided
to protect the internal control circuit, from which option-
al controls can be connected e.g. Internal or external
timeclock that can be installed in the control panel.
Protection against frost
If the boiler is not in regular daily use during
cold periods, it is recommended to fit in
a frost-sensing thermostat to prevent the
system from freezing.
The boiler is NOT fitted with frost protection. If the
boiler is being installed in a position where freezing
could take place, then a suitable external frost-sens-
ing thermostat should be fitted.

Display of the level of
performance (default display)
The first LED is green in normal operation,
red in case of problem. The others are always
yellow when turned on. When the green LED
