1PRODUCT TECHNICAL SPECIFICATION
1.1 FUNCTION DESCRIPTION
Tank type water heater (the heater hereinafter) is designed for the accumulation heating of service water by
electric energy. Water is heated by an electric element in an enameled thermally insulated tank at the time
defined by the power supplier. At the time of the heating, the element is controlled by thermostat on which
the desired temperature can be set (ranging from 0 °C to 77 °C). Once the selected temperature is reached,
heating interrupts automatically. Water accumulated in the tank is then used for consumption. The tank
keeps constant pressure of water from the water main. If the combination faucet hot water valve is opened,
water from the water supply conduit pressed out by cold water pressure flows out of the heater. Hot water
flows out through the top part, and water flowing in remains in the bottom part of the heater. Pressure
principle allows hot water withdrawal at any place from the heater.
1.2 ADVICE FOR CUSTOMERS
1.2.1 HOT WATER CONSUMPTION
Consumption of hot water in households depends on the number of people, amount of sanitary
equipment, length, diameter, and insulation of piping in the flat, or on individual habits of users.
The cheapest option of water heating comes at the time when the electricity rate is reduced.
Find out in what time intervals your electricity supplier provides reduced tariff and, depending
on that information, select relevant volume and power input of the heater so that your hot
water consumption covered the needs of your household.
1.2.2 ENERGY SAVING
The heater is insulated with quality polyurethane Freon free foam. Set the temperature of the
heater's thermostat to that level only that you need to run your home. Thus you will reduce
electricity consumption, as well as the amount of lime sediments on the walls of the receptacle
and on the electric body.
1.2.3 EMERGENCY POWER CONSUMPTION
According to current legislation, the standby consumption is stated in the value of annual
consumption of electric energy (kWh), which is measured according to the corresponding load
profile and calculated according to the formulas and requirements of EU Regulation
No. 812/2013.

2OPERATION AND FITTING INSTRUCTIONS
2.1 OPERATING CONDITIONS
The tank shall only be used in accordance with the conditions specified on the power plate and
in instructions for electric wiring. Besides legally acknowledged national regulations and
standards, also conditions for connection defined in local electric and water works have to be
adhered to, as well as the installation and operation manual.
The temperature at the place of heater installation must be higher than +2 °C; and the room
must not freeze. The appliance has to be mounted at a convenient place, it means that the
appliance must be easily available for potential necessary maintenance, repair or replacement,
as the case may be.
If water is strongly calcareous we recommend that any of the common decalcifying devices was
installed with the appliance, or that the thermostat was set to the minimum operating
temperature of 55 °C (setting to position „OPTIMUM“) - Figure 10. For proper operation,
drinkable water of adequate quality shall be used. To avoid potential sediments, we recommend
that the device was installed together with a water filter.
2.2 WALL MOUNTING
Prior to the mounting check the bearing capacity of the wall and the material it is made of,
considering the weight of the heater filled with water. Depending on the wall material choose
adequate fixtures. Should you have any doubts regarding the wall bearing capacity, consult the
suspension with a building specialist. The minimum diameter of 4 bolts for suspending the
heater is 8 mm. When mounting the anchor bolts follow the manual provided by the anchor
bolts' manufacturer.
Thermostat and no other part of the control panel is not a bearing part which can be used for
any handling with the heater.
If the hot water heater is mounted in a tight, smaller space, or in an intermediate ceiling, etc.,
you have to make sure that the connecting side of the appliance (connections to water supply,
area for electric plugging) remained accessible and no heat accumulation occurs. Free space of
up to 600 mm from the bottom edge of the heater has to be available under the heater. When
mounted directly under the ceiling, the distance from the ceiling has to be 50 mm at least.
If the water heater is mounted in enclosed areas, inter-ceilings, built-in structures and recesses,
ensure sufficient access to service fittings, electrical terminal boards, anodes and manholes.
Minimum spacing from manhole is 600 mm.

- 9 -
Mount the water heater in vertical position. The fixing wood screws must have guaranteed
spacing t=180 mm and spacing F according to the heater volume (Figure 3) or with hinges.
2 upper hinges are attached to the wall and 2 lower hinges are fitted into the bottom holes on
the heater, the lower hinges serve as abutment (Figure 4). Hinges (4 pcs) are included in
package.
Figure 3
Figure 4
The ONE heater can also be installed in a horizontal position. Considering the laws of physics,
its energetic performance drop will always occur due to deteriorated stratification of water.
However, neither lifecycle nor terms of warranty are changed thereby. Our heaters are tested
for operation in the horizontal position. In use in the horizontal position it is recommended that
the user set a temperature higher on the thermostat than factory optimum value.
Recommended value is 65 °C.
Direction of placement - to the left due to the fact the heating flange must be placed in a lowered
reservoir.
When installing in a horizontal position, only two bolts may be used for hanging (upper holes).

For proper operation in the horizontal position it is necessary to change the cold water input
for hot water output and vice versa (swap of blue and red ring is recommended as well); at the
same time it is necessary to remove PEX tube from the left (lower in the horizontal position)
mouthpiece.
Figure 5
2.3 PLUMBING FIXTURE
The heater connects to water distribution tubes with G 3/4“ thread in the bottom part of the
heater. Blue - cold water supply, red - hot water outlet. For potential disconnection of the heater,
the service water inlets and outlets must be provided with screw coupling Js 3/4“. The safety
valve is mounted on the cold water inlet identified with a blue ring.
The heater must be equipped with a membrane, spring-loaded safety valve. Safety valves with
fixed pressure settings from the manufacturer are used for the assembly. Each individually
lockable heater must be fitted with a cap on the cold water inlet, a test valve or a stopper to
check the operation of the check valve, with a check valve and a relief valve (Figure 6). The safety
valve with a check valve is supplied with the heater.
It is necessary to check the safety valve each time before putting it into operation. It is checked
by manual moving of the membrane from the seat, turning the make-and-break device button
always in the direction of the arrow. After being turned, the button must click back into a notch.
Proper function of the make-and-break device results in water draining through the safety valve
outlet pipe. In common operation, such a check needs to be implemented at least once a month,
and after each heater shutdown for more than 5 days. Water may be dripping off the drain pipe
of the safety valve; the pipe must be open into the air, pointed down; environment
temperatures must not drop below zero.
Find necessary pressure values in the table below - Table 3.
Heaters must be provided with a discharge valve mounted on the cold service water inlet to the heater for
potential disassembly or repair. When assembling the security equipment, follow the standard.

2.4 ELECTRICAL INSTALLATION
2.4.1 GENERAL INFORMATION FOR ELECTRICAL INSTALLATION
Perform the connection according to the scheme. Factory connection must not be changed! (Figure 8).
The degree of protection of electric parts of the heater is IP 44. The power input of electric element is 2.000 W
(OKHE ONE/E 50 - 120), 1.100 W (OKHE ONE/E 30).
Figure 8
It is necessary to observe the below requirements during the electric wiring.
•The wiring diagram is attached to the heater on the side of the electric installation cover
(Figure 8).
•The electric installation may only be connected, repaired and inspected only by a person
authorized to perform that activity.
•Professional connection must be confirmed on the warranty card, or supported by
another document.
•The heater is connected to 230V/50Hz power supply by a fixed movable cable (depending
on the connection method).
•When installing in bathrooms, laundry rooms, rest rooms and showers, it is necessary
to follow the relevant standard.
•The degree of protection of electric parts of the heater is IP 44.
•Adhere to the protection against electric shock according to the standard
If the supply cord is damaged, it must be replaced by a company (person) authorized to such
activity in order to avoid a hazard.

- 13 -
2.5 OPERATING ACTIVITY
After the heater is connected to the electric network, the heating element starts heating the water. An
electronic thermostat is used to control the temperature and water heating. The thermostat control range
is 0 °C to 77 °C. The temperature is indicated on the display. The thermostat displays the current measured
temperature. Use the control knob to set the desired cut-off temperature. Turn the knob to the right to set
a higher temperature, turn it to the left to set a lower temperature. When the cut-off temperature is set, the
digits on the display are flashing - indicating the user has set the desired temperature. After the desired
temperature has been set, the value remains flashing for 5 seconds, then the current temperature is
displayed. The heating indicator is on the right side of the display. The light indicates heating.
Error, fault messages: E1 - flashing - fault of the temperature sensor (broken sensor, short circuit), indicated
on the display. Water heating is not working during the fault indication.
The round thermostat knob must be handled with care, do not overturn the defined position, and avoid
stronger shocks and impacts.
For long-term operation without use, it is advisable to set the thermostat to the position 5 °C to 10 °C (set
the thermostat control to the “snowflake” symbol) to avoid freezing or turn off the power supply into the
heater. Setting the thermostat to the zero position does not mean the heater has been turned off.
In case of a power failure, the display turns off, it means also when the heating is turned off
according to the HDO signal. The thermostat setting knob is still active, so by turning it you
can change the temperature, which only takes effect when the power is restored.
2.6 FIRST COMMISSIONING
Before opening the power supply, the tank must be filled with water. The process of first heating
must be executed by licensed professional who has to check it. Both the hot water outlet pipe
and safety armature parts may be hot.
During the heating process the pressurized connection water that increases its volume due to
heating must drip off the safety valve. In non-pressurized connection water drips off the
overflow combination faucet. When heating is finished, the set temperature and the actual
temperature of consumed water should be roughly equal. After connecting the heater to the
water main and electrical power system, and after checking the safety valve (following the
instructions attached to the valve), the heater can be put into operation.
Before fist putting into service or after a longer shutdown the appliance has to be rinsed out and
flushed yet before heating is activated. Before heating starts, the tank must be completely filled
with water and the system properly flushed and vented. First heating of the tank has to be
watched.

- 14 -
Procedure of putting the heater into operation:
1. Check the water main and wiring. Check proper placement of operating and safety thermostat
sensors. The sensors must be inserted all the way in; first the operating and then the safety
thermostat.
2. Open the hot water valve on the combination faucet.
3. Open the cold water inlet valve to the heater.
4. As soon as the water starts running through the hot water valve, the heater is filled, and the valve
can be closed.
5. In case of leakage (of flange lid), we recommend that the flange lid bolts are fastened.
6. Screw down the electric installation guard.
7. When hot service water is heated by electric energy, switch on the power supply.
8. When commencing operation, flush the heater until the cloudiness in the water is gone.
9. Make sure to fill in properly the warranty certificate.
2.7 PUTTING OUT OF SERVICE, DISCHARGE
If the hot water heater is put out of service for a longer time, or if it is not going to be used it
has to be drained and disconnected from the electric supply network. The switch for the supply
lead or the fuse cut-outs have to be shut off.
At places with permanent risk of frost the hot water heater must be drained before the cold
season starts if the appliance remains out of service for several days and if the power supply is
disconnected.
Drainage of service water shall be performed after closing the shut-off valve in the cold water
supply piping (through the discharge valve for safety valve combination), and with simultaneous
opening of all hot water valves of connected fittings (water can be also drained through safety
valve; for that purpose, the safety valve is turned to the "Check" position). Hot water may
outflow during the drainage! If there is a risk of frost it has to be considered that not only the
water in the hot water heater and in the hot water piping may get frozen but also the water in
the entire cold water supply piping. It is therefore advisable to drain all fittings and piping that
carry water, up to the part where the house water meter is installed (connection of the house
to water main) which is not jeopardized by frost. When the tank is to be used again, it has to be
filled with water and one needs to make sure that the water flowing out at the hot water valves
did not contain any bubbles.
2.8 INSPECTION, MAINTENANCE & CARE FOR THE APPLIANCE
During the heating process the water that increases its volume during the heating must visibly
drip off the safety valve outlet (in non-pressurized connection this water drips off the
combination faucet valve). In full heating (about 77 °C) the volumetric water gain is approx. 3 %
of the tank capacity. The function of the safety valve has to be checked regularly. If the safety
valve control knob is lifted or turned to the “Control” position, the water must flow out easily,
without any obstacles, from the safety valve element to the outfall line. In common operation,
such a check needs to be implemented at least once a month, and after each heater shutdown
for more than 5 days.

- 15 -
Attention! In doing so, the cold water supply pipe and the connection fitting of the tank may get
heated! If the hot water heater does not work, or if hot water is not withdrawn, no water shall
drip off the safety valve. If water drips, then the water pressure in the supply piping is either too
high (if higher than 4.8 bars, a pressure control valve has to be fitted), or the safety valve is
defective. Please call a specialized plumber immediately!
If water contains too many minerals, an expert has to come to remove the scale that forms inside
the tank, as well as free sediments. This has to be performed after one or two years of operation.
The cleaning is carried out through the hole in the flange - dismantle the flange lid and clean the
tank. A new sealing has to be used for re-fitting. Since the inside of the heater has special enamel,
which must not get in contact with the scale removing agent - do not work with a lime pump.
Remove the lime layer with a timber and suck it off, or wipe it off with a clout. After that, the
appliance must be rinsed thoroughly, and the heating process is checked the same as during the
initial putting in operation. Do not use any abrasive cleaning agents (such as liquid sand,
chemicals - acid, alkaline)or dye thinners (such as cellulose thinner, trichlor, and the like)to clean
the outer shell of the heater. For cleaning use a wet clout and add a few drops of liquid cleaning
agent for household applications. Repeated heating causes lime scale settling on the receptacle
walls and mostly on the lid of the flange. Lime scale settling depends on hardness of heated
water, its temperature and on the volume of hot water used.
We recommend checking and cleaning the tank from scale and eventual replacement of the
anode rod after two years of operation. The anode life is theoretically calculated for two years
of operation; however, it changes with water hardness and chemical composition in the place
of use. Based on such an inspection, the next term of anode rod exchange may be determined.
If the anode is only blocked with sediments clean its surface and, if used up, mount a new one.
Have a company in charge of service affairs deal with the cleaning and exchanging of the anode.
When draining water from the heater, the combination faucet valve for hot water must be open,
preventing occurrence of under-pressure in the heater tank which would stop the water from
draining.
