General
ELK 9M is an electric heater that can be used to sup-
plement the heating capacity of your MHI climate unit.
When the heating demand is greater than the climate
unit’s capacity, the electric heater connects automat-
ically. The electrical equipment is adapted to the cli-
mate unit’s function.
The electric heater is in principle an immersion heat-
er mounted in a water container or an electric boiler
without a water heater. The steel electric coils and
electric boiler tube are made of steel which gives a
very good service life.
Thanks to a small water volume and a well-insulated
electrical heater, ELK 9M has very small heat losses.
Compatible products
Connection is di󰀨erent depending on which product
ELK 9M is to be used with.
These products can be connected directly to ELK 9M:

Assembly
The electric heater must be installed upright (see im-
age below).
Free space of 500 mm is required in front of the water
heater for service. If this is not possible, detachable
connections must be used.

Pipe connections
General
The pipe installation must be carried out in accor-
dance with applicable standards.
A circulation pump must be used to ensure the ow
over the immersion heater. If the heating system
valves can close the circulation completely, the by-
pass valve must be installed so that the ow through
the electric heater does not stop. In closed installa-
tions an approved safety valve and pressure expan-
sion vessel must be used.
NOTE
The pipe work must be ushed before the electric
heater is connected, so that any contaminants do not
damage the component parts.
CAUTION
Also see the installer manual for your heat pump/in-
door module.
Draining
The system is most easily drained by installing a
drainage valve at the lowest point on the pipe instal-
lation. The remaining water in ELK 9M is drained
through the return line connection (XL2), see “Com-
ponent location” on page 5. If the return line connec-
tion on ELK 9M is normally used for draining the unit,
a drain valve can be installed here.

Electrical connection
NOTE
All electrical connections must be carried out by an au-
thorised 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 9M.
ELK 9M must be installed via a circuit breaker with a
minimum breaking gap of 3mm.
ELK 9M contains overheat protection and two con-
tactors to control the two power steps 3 kW and 6 kW
respectively. For best function the power should be
binary controlled, that is to say 3, 6 and 9 kW.
