CAREFULLY READ THIS MANUAL BEFORE INSTALLING THE WATER HEATER! Dear Customer, The Works Cooperative of Dražice – Machine Plant, Ltd., would like to thank you for your decision to use a product of our brand. With this guide, we will introduce you to the use, construction, maintenance and other information on electrical water heaters.
1 PRODUCT TECHNICAL SPECIFICATION 1.1 FUNCTION DESCRIPTION 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. 1.2 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, reducing the risk of corrosion.
2 OPERATION 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 heater is connected to the 230 V/50 Hz electric network using a fixed moving conductor with a switch that turns off all network poles and the circuit breaker (protector).

Heating unit 3-6 kW The 3-6 kW heating unit allows 4 types of connection based on either required time of heating or possibilities of electric network in the place of use. TPK 3-6 kW R ~ 1 kW To achieve chosen performance of the heating unit, connect the inlet conductor to L1, L2, L3, and N terminal board, and interconnect the clips on the 1-10 terminal board in...
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.
2.4 FIRST COMMISSIONING 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: check the water main and wiring; Check proper placement of thermostat sensors. The sensors in the well must be inserted all the way in;...
2.5 HEATER CLEANING AND ANODE ROD EXCHANGE Repetitive water heating causes limestone sediment on both the enamelled tank walls and chiefly the flange lid. Lime scale settling depends on hardness of heated water, its temperature and on the volume of hot water used.
3 OPERATION OF THERMOSTAT 3.1 SERVICING 3.1.1 OPERATION DEVICES OF THE OKCE 100-125 S/2.2 kW HEATER Thermostat's control panel Thermostat knob Figure 18 3.1.2 TEMPERATURE SETTING Water temperature is set by turning the thermostat knob. The desired symbol is adjusted against the fixed point on the control panel (Figure 9).
Adjusting the thermostat knob 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 55℃. Select the "ECO“ symbol as the maximum. 3.2 MOST FREQUENT FUNCTION FAILURES AND THEIR CAUSES FAILURE SYMPTOM INDICATOR...
4 IMPORTANT NOTICES 4.1 INSTALLATION REGULATIONS Without a proof issued by a professional company about performed electrical and plumbing fixture the warranty shall be void. It is necessary to check the protective magnesium anode periodically and replace it if necessary. No stop valves can be put between the heater and the safety valve.
5 ASSEMBLY GUIDE FOR ZIP-FASTENER INSULATION (only applies to heaters of 750 and 1,000 litre capacity) Insulation can be mounted by two people only; by three for bigger boilers. It can be performed in areas where temperature reaches at least 18°C. If the insulation includes tank bottom insulation, the latter must be mounted first.
