1. USE
OKCE line water heaters use only electricity for heating. Their nominal performance provides sufficient amount of
hot water for flat units, premises, restaurants, and similar establishments.
2. PRODUCT DESCRIPTION
The heater tank is welded from a steel sheet; it is entirely coated with hot water resistant enamel. For additional
corrosion protection a magnesium anode is mounted in the upper part of the heater to adjust the electric potential
inside the tank, lowing the risk of corrosion. All types have the outlets of hot and cold water and a circulation
opening welded to them. The tank is insulated with 65 mm of polyurethane foam. The heater shield consists of a
steel, powder-paint coated, sheet; the connecting parts are metal coated. Under a plastic cover on the side of the
heater, there is a cleaning and revision opening ended with a flange; various performance heating units may be
mounted into the opening. The heater is to be placed on the ground.
Tanks between 100 and 250 litres are tested with the pressure of 0.9 MPa; 300 litre tanks are tested with 1.5 MPa.

Water heater is equipped with a universal electric heating unit with either a set or adjustable heating elements'
performance (except OKCE 300 S/1 Mpa). A heating unit consists of a flange, to which one or three wells for
ceramic heating elements and one thermowell are welded (see fig.). A unit is attached by either 8 M 10 screws with a
168 mm clearance or 12 M 12 screws with a 210 mm clearance. In the wiring plastic cover, there is a thermostat and
a safety fuse; heater operation control light; and a lead-in wire bushing.
The sensors must be inserted all the way in; first the thermostat and then the safety fuse.
The performance of heating unit may be adjusted based on either required heating time or connecting possibilities of
electric energy distribution in the place of use.

After the heater is connected to electric network, the heating element starts heating water. The element is turned on
and off by a thermostat. Thermostat can be set as per your need within the range from 5°C to 74°C. We recommend
setting service water to maximum temperature of 60°C. This temperature ensures an optimal operation of the heater,
reduces heat losses and saves electricity. After reaching the temperature set, the thermostat switches off the electric
circuit and thus discontinues water heating. The control light signals if the element is in operation (light is on) or if it
is off (the light goes out).
When shutting the heater out for an extended period, in winter you can set the thermostat to the snowflake sign
preventing the water from freezing, or turn off the inlet of electricity to the heater.
Connection, repairs, and wiring inspections may only be implemented by company (person) authorised to such
activity. Expert connection must be confirmed on the warranty certificate.
The heater is connected to the electric network using a solid moving conductor with a switch that turns off all
network poles and the circuit breaker (protector).
Installations in bathrooms, laundromats, rest rooms and showers must comply with ČSN 33 2000-7-701.
The degree of protection of electric parts of the heater is IP 44.
Respect rules of protection against electrical injuries in accordance with ČSN 33 2000-4-41.

Temperature setting
Teplota vody se nastavuje otočením knoflíku termostatu. Požadovaný symbol se nastaví proti pevnému bodu na
ovládacím panelu.
Notice: Adjusting the thermostat selector to the left backstop does not mean permanent shutoff of the heating
element.
When the heater is in use without blocking the daily rate, we do not recommend the temperature to be set above
65°C.
The maximum value to select is “60“.
Limiting the regulation range; locked settings.
For various safety reasons (unintentional scalding, preventing children or unauthorised person from handling), the
regulation range can be limited, or the setting on the thermostat blocked.
Regulation limited: - pull off the thermostat knob (it will be hard for the first time), and you will find two 2.15mm
cylindrical pins on the back side of the knob
- pull off one pin and insert it to the corresponding hole of the selected maximum temperature.
- put the knob back on to the stop
To block the setting: - set the selected temperature
- pull off the thermostat knob without changing the setting, there are two pins on the back
side of the knob
- pull off both of them and fit them into the holes corresponding with the selected
temperature so that the gap between the pins was without a hole, and the position was
opposite the set temperature.
7. SECURITY EQUIPMENT
Each hot service water pressure heater must have a membrane spring loaded with a safety valve. Nominal clearance
of safety valves is defined in the ČSN 06 0830 standard. 300 l heaters are not equipped with a safety valve. The
safety valve must be easily accessible, as close to the heater as possible. The input pipes must have at least the same
clearance as the safety valve. The safety valve is placed high enough to secure dripping water drain by gravity. We
recommend mounting the safety valve onto the branch led above the heater. This allows easier exchange without
having to drain the water from the heater. Safety valves with fixed pressure settings from the manufacturer are used
for the assembly. Starting pressure of a safety valve must be identical with the maximum allowed heater pressure,
and at least 20% higher than the maximum pressure in the water main. If the water main pressure exceeds such
value, a reduction valve must be added to the system. No stop valves can be put between the heater and the safety
valve. During the assembly, follow the guide provided by the safety equipment manufacturer.
Before putting the safety valve into operation it always needs to be checked by manual removal of the membrane
from the valve seat and 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 can drip from the safety valve through the
drain pipe; the pipe must be freely open to the atmosphere, placed vertically and shall be in an environment free of
temperatures below freezing.
When draining the heater, use a recommended drain valve. First, close water supply into the heater.
Find necessary pressure values in the following table:
For proper safety valve operation, a
backflow valve must be mounted on the
input pipes, preventing spontaneous
heater draining and hot water penetrating
back into the water main.
When assembling the security equipment, follow the ČSN 06 0830 standard.
8. PUTTING THE HEATER INTO OPERATION
After connecting the heater to the water main, electrical power system, and after checking the safety valve (following the
instructions attached to the valve), the heater can be put into operation.
Procedure:
a) Check the water main and wiring; Check proper placement of thermostat sensors;
b) Open the hot water valve on the combination faucet;
c) open the cold water inlet valve to the heater;
d) when the water starts flowing through the hot water valve, the filling of the heater is finished and the valve needs to be
closed;
e) If a flange lid leak is discovered, the flange lid bolts need to be tightened;
f) Fasten the electric installation cover;
g) When commencing operation, flush the heater until the cloudiness in the water is gone.
h) Make sure to fill in properly the warranty certificate.

9. HEATER CLEANING AND ANODE ROD EXCHANGE
Repetitive water heating causes limestone sediment on both the tank walls and chiefly the flange lid. The sedimentation
depends on the hardness of water heated, its temperature, and amount of hot water consumed. We recommend checking
and cleaning the tank from scale, if necessary, inspection and possible replacement of 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. Have the company in charge of service affairs clean and exchange the anode. When discharging water from
the heater, the mixing valve of the hot water tap must be open in order to avoid creating underpressure that would prevent
water discharge.
10. IMPORTANT NOTICES
-Check and exchange the Mg anode regularly.
-No stop valves can be put between the heater and the safety valve.
-If the overpressure in the eater main exceeds 0.48 MPa, a reduction valve must be mounted before the safety valve.
-All outlets of hot water must be equipped with a combination faucet.
-Before filling the heater with water for the first time, it is recommended to fasten the flange connection nuts of the tank.
-It is not allowed to handle the thermostat, aside from temperature resetting with a control button.
-All electric installation handling, setting, and regulation feature exchange, may only be implemented by a service
company.
Notice: To prevent formation of bacteria (e.g. Legionella pneumophila) within stack heating it is recommended, if
absolutely necessary, to increase the temperature of HSW periodically for a transitional period of time to at least 70°C. It
is also possible to make use of another way of HSW disinfecting.
11. SPARE PARTS
- Flange lid - flange lid seal - set of M12 (or M10) bolts

13. FURTHER INFORMATION
Notice: 300-1000 litre capacity heaters are screwed onto the bottom wooden palette with M12 screws. When the heater is
released from the palette and prior to its putting into operation, 3 adjustable legs supplied as the product accessories have
to be installed. With these legs, the heater may be positioned vertically to the base, within 10 mm.
Disposal of packaging material and functionless product
A service fee for providing return and recovery of packaging material
has been paid for the packaging in which the water heater was
delivered.
The service fee was paid pursuant to Act No. 477/2001 Coll., as
amended, at EKO-KOM a.s. The client number of the company is
F06020274. Take the water boiler packages to a waste disposal place
determined by the town. When the operation terminates, disassemble
and transport the discarded and unserviceable heater to a waste
recycling centre (collecting yard), or contact the manufacturer.
14. FUNCTIONAL DEFECTS
Do not try to repair the failure yourselves. Seek either expert or service help. It does not take much for an expert to
remove the defect. When making a repair appointment, report the type and serial number you find on the performance
plate of your water heater.

15. ASSEMBLY GUIDE FOR ZIP-FASTENER INSULATION
(Only concerns heaters with the capacity of 750 and 1,000 litres)
Two people are enough to implement the insulation assembly; three people are required for larger boilers; the assembly
must be implemented in areas with the temperature of at least 18 oC.
If the insulation includes tank bottom insulation, the latter must be mounted first. The insulation is then inserted around
the boiler (heater), respecting the pre-pressed insulation openings. Pull gently in the direction of the arrows to put the two
zip insulation sides together (see Fig. 6) so that the insulation does not draw down and the openings in the insulation fit
the boiler inputs and outputs. It must be secured that, before closing, both halves of the zip-fastener are not further than 20
mm apart (see Fig.7). No foam must get into the zip-fastener on closing.
After the insulation coat is properly mounted and the zip-fastener closed, insert the top lid made of foam material and
cover it with either a foil cover or a plastic lid. It is also possible to glue the outlet caps to connection places (see fig. 8).
The insulation must be stored in dry areas only.
We take no responsibility for damages caused by not respecting this guide.
