▪Before using the hot water, be sure to check its temperature.
▪Adjust the indoor temperature according to your needs.
▪Homogeneous heating provision in the areas of the heating environment
in accordance with the purpose of use increases savings.
2. SUGGESTIONS FOR ECONOMICAL USE

4
▪The fact that the required temperature value for each section can be
adjusted using thermostatic valves with radiators increases the savings.
However, using the room thermostat and thermostatic valve at the same
time can cause problems if installed in the same room.
▪In order for thermostatic valves to detect the ambient temperature correctly,
curtains or items that may disrupt the air flow in the environment should be
positioned appropriately.
▪Room thermostat should be positioned at an appropriate height and
away from windows, furniture or heat sources so that it can perceive the
real temperature of the environment it is in.
▪Prolonged ventilation of heated environments increases energy loss.
Ventilation should be done for short terms but if long-term ventilation is
required, closing the radiator valves present in the environment or lowering
the device heating setting will save energy.
▪If the temperature of the device is lowered at night or when the home
is unoccupied for a short time, while the ambient temperature can be
kept at a certain level saving can also be achieved.
▪Adjusting the operating temperature of the device according to the
outside temperatures will save money.
▪Adjusting the domestic water temperature according to your needs and in
a way that does not require use of cold water to make it tepid, saves
money.
▪Use water wisely. Use of water with care increases savings.

5.1. Installation Conditions and Safety Warnings
5. DEVICE INSTALLATION

8
▪Prior to installation, all system piping should be carefully flushed to remove any
residue that could impair the operation of the device.
▪When the pressure of the heating system rises above 3 bar, water discharge
starts from the safety valve.
▪There is no need for a safety valve in the mains hot water circuit, but make sure
that the water pressure does not exceed 6 bar.
If in doubt, have a pressure reducer installed at the mains cold water inlet to
the property.
▪The environment in which the device is installed should be away from parts and
protrusions which could block or obstruct access during maintenance or repair.
There must be sufficient space around the device for maintenance and repair.
▪The electrical connection of the device must be made with a suitable cable, fuse
and residual current relay and grounding connection must be present.
▪The wall where the boiler is to be mounted must be capable of supporting the
weight of the device.
Fix the plugs by drilling the device mounting holes in the locations selected in
accordance with the conditions stated above. Using the holes you drilled, screw your
device from the bottom to the top and check that it is stable.
The heating system should be installed using pipes of suitable diameter to ensure
adequate circulation of the heating water. Choosing heating pipes in smaller diameter
than they should be and narrowing or blockages in the installation may cause
insufficient heating circulation. Connections to the device must be easily removable
when necessary. There should be separate shut-off valves at the heating inlet and
outlet of the device, and a Magnetic filter at the heating return between the valve and
the device. There must be a valve and an inline lime scale inhibitor at the cold-water
inlet of the boiler.
It should be ensured that the wall, where the boiler is to be mounted, can carry the
full weight of the device and that the mounting material is securely fixed.

For UKDAX-xxEDT and UKDAX-xxEDM models, this is done with the blue filling tap
on the bottom of the device. The filling should be done by following the instructions
below.
▪Make sure that the cold-water inlet valve of the device is open.
▪Turn on the filling tap.
▪Open the air vents and discharge the air accumulated in the radiators
and shut them when water starts to flow.
▪When the air accumulated in the radiators is discharged, there may be a
decrease in the water pressure of the heating system. Make sure that the
water pressure of the heating system is between 1-1,5 bars, if there is a
decrease, fill it up by opening the filling tap.
For UKDAX-xxETT and UKDAX-xxETM models, this process is done using the filling
valve to be connected to the heating system. For this, a valve connection must be
made from the cold water system to the heating system. The filling valve should be
close to the device and in a position that sees the pressure gauge on the device.
After the filling valve, there must be a silt trap. The filling should be done by following
the instructions below.
▪Turn on the heating system water filling valve.
▪When the water pressure gauge reaches 1 - 1.5 bar, turn off the filling tap.
▪Open the air vents on the upper side of the radiators and discharge the air
accumulated in the radiators and turn them off when water starts to flow.
5.2.1.1. Filling the Heating System for EDT and EDM Models
5.2.1.2. Filling the Heating System for ETT and ETM Models
After the heating system is filled, it should be carefully checked for any water
leak.
If the filling tap is left on and the pressure of the heating system exceeds 3
bar, water discharge starts from the safety valve inside the device.

10
▪When the air accumulated in the radiators is discharged, there may be a
decrease in the water pressure of the heating system. Make sure that the
water pressure of the heating system is between 1 and 1.5 bar, and if there is
a decrease, turn on the filling tap and increase it.

Electrical installation should be carried out by qualified personnel using an
appropriate cross-sectioned-cable chosen according to the device capacity andcable
length. There should be a separate residual current relay with appropriate
specifications and a fuse with suitable amperage value, both capable of completely
cutting the electricity supply to the device off, and the fuse should be located close to
the device. The device must be grounded.
