  • Page 4: Product Technical Specification

    1 PRODUCT TECHNICAL SPECIFICATION 1.1 FUNCTION DESCRIPTION The heater is designed for the so-called accumulation heating of service water by electric energy, or by thermal energy through exchanger. Water is heated by an electric element at a time determined by the electricity supplier, or by a heat exchanger in an enamelled thermally insulated tank. At the time of the heating, the element is controlled by thermostat on which the desired temperature can be set (ranging from 5 and 74°C).

  • Page 11: Operation And Fitting Instructions

    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.
  • Page 12 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.

  • Page 13: Plumbing Fixture

    2.3 PLUMBING FIXTURE The heater connects to water distribution tubes with G1/2“ 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 1/2“. The safety valve is mounted on the cold water inlet identified with a blue ring.
  • Page 14 It is recommended to install stop valves on the heating water inlet and outlet (for possible dismantling of the heater). The valves have to be as close to the heater as possible to avoid higher thermal losses. Figure 9 Figure 10 - 14 -...

  • Page 15: Electrical Installation

    • The heater is connected to the 230 V/50 Hz electricity supply using a fixed moving conductor with a switch that turns off all network poles and the circuit breaker (protector). • In the OKC 80 - 125 and OKC 100 - 125/1m heaters, after wall mounting and adjusting the distance from the wall by M8x80 rectifying screw, connect the external protective connection wire to the rectifying screw.

  • Page 16: Operation

    Figure 12 2.5 OPERATION a) Water heating by electric energy After the heater is connected to electric network, the heating element starts heating water. The element is turned on and off by a thermostat. After reaching the temperature set, the thermostat switches off the electric circuit and discontinues water heating.

  • Page 17: Putting Out Of Service, Discharge

    During the heating process the pressurised connection water that increases its volume due to heating must drip off the safety valve. In non-pressurised connection water drips off the overflow combination faucet. When heating is finished, the set temperature and the actual temperature of consumed water must be more-or-less the same.

  • Page 18: Inspection, Maintenance & Care For The Appliance

    2.8 INSPECTION, MAINTENANCE & CARE FOR THE APPLIANCE During the heating process the water that increases its volume during the heating must drip off the safety valve outlet (in non-pressurised connection this water drips off the combination faucet valve). In full heating (about 65oC) the volumetric water gain is approx. 3% of the tank capacity.
