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 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 enamelled thermally insulated tank at the time defined by the power supplier. The element is at the time of heating controlled by a thermostat the temperature of which can be adjusted continuously (within the range between 5 °C and 74 °C).

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.
Universal suspension The use of the suspension even for the screw spacing during the replacement with a heater of another type. The heater verticality after the release of the connecting screws can be aligned by means of slight turning. Figure 5 If the hot water heater is mounted in a tight, small 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.

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.
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 9). In the electric wiring casing remove the partition corresponding with the input wire diameter Ø8 or Ø10 (Figure 8).
2.5 OPERATING ACTIVITY 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. The control light signals if the element is in operation (light is on) or if it is off (the light goes out).
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 on all poles. The switch for the supply lead or the fuse cut-outs have to be shut off.
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.
Thermostat and no other part of the control panel is not a bearing part which can be used for any handling with the heater. 3.1.1 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 12, Figure 13).
4 IMPORTANT NOTICES 4.1 INSTALLATION REGULATIONS Without a confirmation of performed electrical installation issued by an authorised company, the warranty certificate shall be void. Check and exchange the Mg anode regularly. You have to apply for approval of a local power supplier to connect the heater. No stop valves can be put between the heater and the safety valve.
