1 Important information

ELK 213 is an electric heater intended for heating
buildings and indirect heating of hot water. ELK 213 can
also be mounted together with a boiler, accumulator
tank or heat pump. When installing together with a heat
pump, for example, the electric heater is engaged
automatically as supplementary heating when the
heating demand is greater than the heat pump’s capa-
city.
The stainless steel electric coils and electric boiler tube
are made of acid-resistant steel (SIS 2333), which gives
a very good service life.
ELK 213 contains temperature limiter and contactors to
enable external control of the power.
ELK 213 is equipped with a time relay. Time delay is
recommended when the connected power exceeds 6
kW. The thermostats for the immersion heater and
isolator switch are operated by knobs on the control
panel.

Assembly
The electric heater must be installed upright (see image
below).
A free space of 800 mm in front of the water heater and
500 mm above is required to carry out servicing. If this
is not possible, detachable connections must be used.

General
The pipe installation must be carried out in accordance
with applicable standards.
A circulation pump must be used to ensure the flow
over the immersion heater. If the heating system valves
can close the circulation completely, the bypass valve
must be installed so that the flow through the electric
heater does not stop. In closed installations an approved
safety valve and pressure expansion vessel must be
used.
Caution
Also see the installer manual for your heat
pump/indoor module.
NOTE
The pipe work must be flushed before the
electric heater is connected, so that any con-
taminants do not damage the component parts.
DRAINING
If a drain valve is necessary, it can be installed in the
water heater's drain connection XL10). This connection
can also be used as a circulation pump connection. The
connection is plugged upon delivery.
SAFETY VALVE
In closed boiler installations, the safety valves must be
installed in connection with the highest part of the
electric heater, but not directly on the heater. The con-
nection line must rise continuously.
The safety valve must be "exercised" regularly, at least
four times a year.
NOTE
The pipe work must be flushed before the
electric heater is connected, so that any con-
taminants do not damage the component parts.

Installation alternative
ACCUMULATOR TANK (SP 300)
For installing ELK 213 to SP 300 accessory "Thread
flange kit" is required (Part no. 022 077).
In the event of large hot water demands, ELK 213, in-
stalled on double-jacket accumulator tank type, can be
used to heat the domestic hot water. This is also a good
solution for aggressive or hard water.
Recommended thermostat setting: 75 °C
ELK 213
BOILER WITH INTERNAL WATER HEATER
With the immersion heater installed on an existing boiler,
the existing control equipment is used.
Install the electric heater so that external heating does
not cause overheating, for example, in front of the fire-
box door (to prevent flames blowing out) or next to the
flue pipe (to prevent damaging heat radiation). A suitable
location is normally at the side of the boiler, directly on
the double jacketed heater’s flanges or similar location.
When the electric heater is installed on the existing
wood boiler and is solely responsible for the heating
demand, the flue should be sealed.

NOTE
All electrical connections must be carried out
by an authorised electrician.
Electrical installation and wiring must be carried
out in accordance with the stipulations in force.
The climate unit must not be powered when
installing ELK 213.
ELK 213 must be installed on terminal block X1 via a
circuit breaker with a minimum breaking gap of 3 mm.
The electrical circuit diagram is at the end of this Installer
handbook.
Electrical connection
versions F1345
F1345 has different electrical connection versions de-
pending on when the heat pump was manufactured. To
check which electrical connection applies to your F1345,
check the designation "2.0" visible above the right hand
side of the terminal block as illustrated.
LEK
If ELK 213 is to be controlled externally, the straps
between X8:1-X8:6, X8:2-X8:7 and X1:N1-X1:N2 must
be removed. In addition, the strap between X8:3-X8:5
must be moved so that it runs between X8:3-X8:9.

Power supply
The power cable must be selected for the relevant
power and connected to terminal block X1.
Upon delivery the electric heater has three unopened
cable grommets. These are for supply, external control,
circulation pump and load monitor.
Output
The immersion heater can be set up to a maximum of
13 kW. The delivery setting is 9 kW in two steps.
The immersion heater’s power output is divided into
steps, 7, 9, 11 and 13 kW. Switching to another power
output is performed at the top of the electric water
heater, directly on the immersion heater’s connections
and on terminal block (X8) in the electrical connection.
The power output can be controlled in three steps in all
powers and in two steps for power outputs 7 and 9 kW.
Powers 11 and 13 kW must not be controlled in two
steps. Change-over occurs on terminal block (X8) using
the wiring enclosed.
