1.3 GENERAL EXPLANATIONS
MAKTEK Electric Boiler provides the heating by central boiler heating system and with
radiators connected to the system and provides hot water by heat exchanger.
Installation and services must be in accordance with recent standarts and announced
directives. Our company is not responsible for damages caused from wrong
installation and usage.
Make sure the boiler is operated only to comply the intended use of the boiler. Any
usage which does not comply with the boiler's intended use may cause serious injury,
death or harms to the environment and goods.
ATTENTION ; Only Autorised Services and Manufacturer are responsible for the
boiler.Do not allow other people to interfere with the settings of the boiler.
1.4 C.O.S.H.H
Materials used in the manufacture of this appliance are non-hazardous and no special
precautions are required when fitting or servicing this appliance.
1.5 PREPARATION
1.5.1 Load Check
A load check should be taken into consideration when installing high output boilers.
1.5.2 Boiler Location
The boiler must be installed on a wall that will provide an adequate fixing, and should
be installed in a location that the boiler and pipe-work are not subject to frost and
damp conditions.
1.5.3 Central Heating Installation
Detailed recommendations are given in EN 12828.
Pipes forming part of the useful heating surface should be insulated to prevent any
potential heat loss or frost damage.
Drain valves should be fitted at the lowest point of the system pipe work in an
accessible position.

2.3 OPERATION PRINCIPLE OF THE DEVICE
MAKTEK Omega electric combi boiler provides central heating with the use of panel
radiators or underfloor heating pipes. The primary heating circuit water is heated in the
main heat exchanger with the heating elements. The hot water circulates the installation
with the help of the circulation pump, delivering hot water to the radiators or underfloor
heating pipes.
The boiler also produces domestic hot water to be used in sinks and showers in the house.
The DHW is generated by the plate heat exchanger located inside the boiler.
Electric combi boiler senses the DHW demand when the water tap is opened and the 3-way
valve actuator motor changes postion to divert the hot water to the plate heat exchanger
automatically in order to produce DHW. In winter mode operation, DHW supply is always
prioritized.
2.4 MAIN FEATURES OF THE BOILER

3.1.1 Delivery Content
3.2 INSTRUCTIONS FOR MOUNTING
Boiler should not be installed in humid places such as bathrooms and areas that may
be affected by rain water.
The boiler should be installed on strong walls that can carry it and perpendicular to the
ground.
Spesific space must be left around the for the authorized service to intervene in the
event of a technical breakdown or maintenance. You can find the minimum spaces
required for installation in the below diagram.
Only use the wall plugs, screws and wall mounting plate supplied with the device during
installation.The boiler must be installed vertically (upright position) and checked with a
spirit level so that it can work properly after installation. Failure to do so will invalidate
the warranty.
3.3 MINIMUM SPACES FOR INSTALLATION
At least the following space must be left in order to reach the internal parts of the
device easily when a failure occurs or when maintenance is carried out.
Suggested space is the minimum space and it is favorable to leave more space
depending on the situation.
