EL 160 Eco & EL 500 Eco
1. Installation
1.1 Installation – HVAC
The boiler must be installed in accordance with current national regulations, as well as DHW system requirements.
In addition, the boiler is approved for zero flow but is designed for pump circulation.
To facilitate servicing, pipes and cabling must not be placed over the boiler or attached to the boiler's rear top
cover. The distance between the boiler top and the ceiling should not be less than 900 mm.
The Swedish Electrical Safety Board recommends that an area of 1200 mm in front of the boiler be kept free.
1.1.1 Water Quality / Boiler Water
The following requirements apply:
• Boiler water must not contain salt and lime concentrations at levels that may damage the boiler and increase
the risk of limescale build-up.
• Water hardness must not exceed 10 dH.
• The pH-value of the water must not be too low (min. 7).
• The water must not contain sludge or any other contaminants.
• Requirements regarding water quality must always be met. Good water increases the service life of the boiler.
1.1.2 Glycol in boiler water
It's not uncommon to want to mix glycol into the boiler water.
However, the addition of glycol reduces the heat capacity of the water, i.e. to gain full output the flow must be
increased.
There are different types of glycol but, as a rule of thumb, the following changes will occur:
• A 25 % glycol mixture reduces output by approx. 10 %.
• A 35 % glycol mixture reduces output by approx. 15 %.
• A 50 % glycol mixture reduces output by approx. 30 %.
The values above should be considered as guidelines and should not be taken at face value.
1.1.3 Built-in safety system (factory-fitted)
See chapter 6.
If the boiler to be installed has a built-in safety system, recommendations regarding the safety valve's outlet flow
must be followed. The outlet flow from the safety valve should have a pressure drop of less than 10 % of the
opening pressure, and should discharge safely.
Pressure transmitter factory settings:
• The minimum pressure is set to 0.25 bar
• The maximum pressure is set to 2.85 bar for boilers with 3 bar safety valve
• The maximum pressure is set to 5.85 bar for boilers with 6 bar safety valve
These settings must be checked by the installer and can be adjusted to suit the installation.
Note: At the standard boiler, the pressure switch connection is plugged. Nothing may
be mounted there! Safety equipment must be mounted externally. The electric boiler is
CE-approved as a unit and must not be altered.

1.2 Installation – Electrical
Electrical installation must be carried out by a certified electrician, and must be performed in accordance with valid
regulations.
Connect 230 and 400 V according to the electrical circuit diagram. The control circuit (230V) must be preceded by a
maximum of 16 A fuse.
Cableways or cables should not be placed over or attached to the boiler’s rear roof panel.
Power switch is supplied with factory setting. Its response time should be adjusted after installed current for optimal
release time.
1.2.1 Re-tightening the power cable connections
When the boiler is put into operation, inspection and re-tightening of the power cable
connections must be carried out for the immersion heaters (on the top of the boiler), current
strips and their bolted joints, contactors, incoming phases - zero - earth, and other electrical
connections. See chapter Servicing and "Instruction for Re-tightening".
Inspection and re-tightening must then be carried out after 100 hours of operation, after 1 year and,
thereafter, at intervals of no more than 2 years. A signature is required in the table on page 10 to support
any eventual warranty claim.
Work in the boiler's electrical system may only be performed by a certified electrician.
NOTE! The boiler's electrics must not be put into operation until the water system is full and the boiler has
been bled.
1.3 Installation – Ventilation
The electric boiler must be placed in an area supplied with fresh air intake and of sufficient space, where the ambient
temperature does not exceed 25 °C and does not fall below 0 °C.
Requirements regarding ambient temperature must be strictly adhered to, as these are functional prerequisites for
the electric boiler's internal ventilation/cooling.
1.4 Installation with external control (eg heat pump)
If the electric boiler is to be controlled by an external unit, connection must be done according to the electrical diagram.
The control system defines how to control the boiler, external control, external control input. See chapter 8-10!
2. Commissioning
!
Before commissioning, the entire manual must be read and understood.
1. Make sure that the installation of water, electricity and ventilation is done according to chapter 1 and
that there's water in the system.
NOTE! Wait to connect any boiler external control. Begin with a "clean" boiler.
2. Start the boiler. The program should now start automatically according to the factory default settings.
In order to get a calmer regulation it's recommended to increase the step time, how much is
depending on the conditions (eg. size of water system).
3. Any external control is set according to section 9.8.1 and the manual for external control, e.g. a heat
pump.

EL 160 Eco & EL 500 Eco
3. Overheating protection
3.1 Overheating protection (Thermal cut-off)
The boiler is equipped with a thermal cut-off (Max. thermostat - Tz), which has been set to 105°±5° C. This will
interrupt the control circuit voltage to the boiler's contactors and release the circuit breakers. The max. thermostat
is reset at about 70 ° C. Before the boiler has cooled down, it is not possible to reset the circuit breaker and
acknowledge the alarm on the display.
To restart the boiler, the circuit breakers inside the boiler must be reset and the alarm on the display acknowledged.
3.2 Circuit breaker (72-504 kW)
The circuit breaker cannot be switched on until the triggered safeguard is reset.

10 EL 160 Eco & EL 500 Eco
4. Servicing
The boiler's control system assists by keeping track of when servicing needs to be carried out. This can be set with
the touchscreen in the Service menu. Error messages are also displayed here, along with suggestions for how to
rectify the error.
After remedial action, the boiler technician/service technician uses the boiler's 4-digit PIN code to perform a reset.
The code is issued once the warranty document has been registered.
4.1 Re-tightening the power cable connections
Inspection and re-tightening must be carried out after 100 hours of operation, after 1 year and, thereafter, at
intervals of no more than 2 years. A signature is required in the table below to support any eventual warranty claim.
The control system's service timer assists with keeping track of servicing intervals (provided the correct values have
been set). Work in the boiler's electrical system may only be performed by a certified electrician.
See the torque image at page 12-13. Sign the table!
4.1.1 Re-tightening performed
4.2 Replacing the air filter
For EL 160 Eco and 500 Eco, the air filter must be replaced once per year. This may need to be done more fre-
quently depending on the boiler room environment. The filter is replaced from the outside.
The article number can be found under the Spare Parts chapter in this manual.
4.3 Safety valve function test
For safe operation and functionality, a function test should be carried out at least once per year. Turn the plastic cap
(pressure relief valve) until the valve opens. The seal wire is usually of the correct length and does not need to be cut.
