5 Installation
In case of third-party gas boiler
INFORMATION
Air purge valves. In case of third-party gas boiler, the
following air purge valves are possible:
▪ Manual air purge valves on the shut-off valves (option
EKBALLV1).
▪ Manual or automatic air purge valve inside the third-
party gas boiler.
▪ Manual or automatic field-supplied air purge valves.
▪ Note: Automatic air purge valves are NOT allowed if
glycol is used.
Before filling the space heating circuit, the gas boiler MUST be
installed.
1 Flush the installation thoroughly to clean the circuit.
2 Connect the water supply hose to the fill/drain point.
Note: The fill/drain point can be:
▪ Field supplied
▪ Part of the existing installation
3 Power up the gas boiler, and make sure you can read out the
pressure indication.
Note: The pressure indication can be:
▪ On the boiler display of the third-party gas boiler
▪ On a field-supplied manometer
4 If an automatic air purge valve was installed, make sure it is
open.
5 Fill the circuit with water until the boiler display indicates a
pressure of ±2 bar (with a minimum of 0.5 bar).
Note: The pressure relief valve of the outdoor unit is designed
to open at 3 bar.
6 Purge air from all manual air purge valves in the system (open,
purge air, close).
7 Check the pressure. If it is too low, repeat from step 5.
8 Turn ON the pump, and check if you can still hear air in the
circuit. After ±1 min, turn it OFF.
Note: To turn the pump ON and OFF, use the air purge
function on the outdoor unit's user interface. See

9 Turn ON the bivalent signal test, and check if you can still hear
air in the circuit. After ±1 min, turn it OFF.
Note: To turn the bivalent signal test, see

10 Purge air again from all manual air purge valves in the system
(especially if you heard air in the circuit).
11 Check the pressure again. If it is too low, repeat from step 5.
12 Disconnect the water supply hose from the fill/drain point.
5.3.5
To fill the domestic hot water tank
See the installation manual of the domestic hot water tank.
5.3.6
To insulate the water piping
The piping in the complete water circuit MUST be insulated to
prevent condensation and reduction of the heating capacity.
To prevent the freezing of the outdoor water piping during winter
time, the thickness of the sealing material MUST be at least 13 mm
(with λ=0.039 W/mK).

During winter, protect the water piping and shut‑off valves against
freezing by adding heat tape (field supply). If the outdoor
temperature can drop below –20°C and no heat tape is used, it is
recommended to install the shut‑off valves indoors.

DANGER: RISK OF ELECTROCUTION
WARNING
ALWAYS use multicore cable for power supply cables.
WARNING
Prevent hazards due to inadvertent resetting of the thermal
cut-out: power to this appliance MUST NOT be supplied
through an external switching device, such as a timer, or
connected to a circuit that is regularly turned ON and OFF
by the utility.
NOTICE
Safety thermostat (normally closed contact). The
outdoor unit does not contain a safety thermostat. Make
sure to install a field-supplied safety thermostat in the heat
emitter system according to the applicable legislation.
However, you cannot connect the feedback signal from the
safety thermostat to the outdoor unit or gas boiler because
there are no terminals for the feedback signal. Because of
this, you also do not have to do any configuration on the
outdoor unit or gas boiler.
In any case, to prevent unnecessary tripping of the safety
thermostat, we recommend the following:
▪ The safety thermostat is automatically resettable.
▪ The safety thermostat has a maximum temperature
variation rate of 2°C/min.
▪ There is a minimum distance of 2 m between the safety
thermostat and the motorized 3‑way valve delivered
with the domestic hot water tank.
▪ The safety thermostat setpoint is at least 15°C greater
than the maximum leaving water temperature setpoint.
In case of dedicated gas boiler
NOTICE
The distance between the high voltage and low voltage
cables should be at least 50 mm.
CAUTION
Do NOT push or place redundant cable length in the unit.
