- Page 2 One should remember that heater output depends on: its electric power; water stream flowing through the appliance. The bigger flow, the lower water temperature on exit (table 1); voltage drop in electrical system. For instance: voltage drop by 10% results in lowering heating output by 19% (table 2). Voltage drop below 185V causes blockage by electronic system possibility of appliance switching on; supplied water temperature. Table 1.

In case of heater’s defect immediately cut off water and power supply. All service and maintenance works can be completed only with power switched off Only original spare parts can be used for repair Casing should never be disassembled while power is on Avoid electronic system to be splashed with water In case of heater’s defect or improper work switch off power and shut off water supply using stopping – suppressing valve. Water tap drain tube sprinkler (strainer) should be cleaned regularly. Power supply system should be periodically checked up (voltage drops), particularly electrical connections. Water flow should be suppressed in such way to avoid excessive temperature (take care of children). 3. Wiring system The heater can only be used previously connected to earthing system. Wiring system should be equipped with differential switch. Minimum wire cross section and fuse value should be selected according to table 3. Before heater’s installation check state of wiring system and particularly terminal. After heater’s connection to wiring system measure voltage drop under load. Fig.2... -

The device can only work in position showed on drawing No 1. Heater’s installation in position other than proper one or without water fil- ter can damage heating element and cause deprivation of guarantee. - Page 6 Fig. 3 Fig. 4 2. Screw heater on. 3. Connect heater in a way showed on fig. 6. Remember to fit water filter as showed on fig. 5. Use flexible hoses designed for pressurized system with rubber gaskets. Do not exchange heater outlet (red colour) with intake (blue colour). Caution! do not screw up hoses nuts too tightly in order to avoid heater’s pipes thread damage. Water filter removal voids guarantee. Filter must be installed as showed on drawing No 5.

Open full water flow through the heater in order to deaerate heating element. 6. Connect heater to the power installation. Fig. 7 Caution! Every single time after re-instalation of the housing it is necessary to check carefully whether blue and red gaskets on pipe ends fit close to the heater’s housing nests. 7. Change sprinkler (strainer) mounted on drain pipe for the one delivered by heater manufacturer.

Page 9: Water Filter Cleaning
7. Water filter cleaning 1. Turn off water inflow to suppressing – shutting off valve and disconnect from power line. 2. Disconnect hose from heater intake. 3. Take out filter (using small screw driver – see fig. 8). Fig. 8 4. Remove dirt from filter. 5. Install filter into heater intake with basket bottom down (Fig. 9) Fig. 9 6. Connect hose to the heater. 7. Open water valve and check tightness. 8. Before power switching on check electronic system is not splashed with water – if so, blow up with air to remove water from electronic circuit board. 9. Adjust according to chapter 6. 8. Cleaning drain tube sprinkler (strainer) 1. Unscrew sprinkler from drain tube. 2. Unscrew bolt from sprinkler. 3. Push out rings from sprinkler. 4. Clean up rings’ ducts. - Page 10 9. defects and repair Water flow too low – blocked water filter (clean it out according to chapter 7) Heater does not start – heater’s inlet exchanged with outlet – water flow suppressed too much – blocked water filter (clean it out according to chapter 7). – water pressure in system too low – lack of power because of blown fuse. Heater does not warm up water but control lamp lights – voltage too low (power installation overloaded) – temperature of entering water too low – water flow too high (adjust water flow according to chapter 6) Water temperature on heater exit too low – water flow too high (adjust water flow according to chapter 6) – temperature of entering water too low...
