CONNECTION TO THE WATER SUPPLY

The water heater is constructed for cross-flow (non-pressure) system of installation. This system enables supply of water only at one outlet point. The connection must be performed correspondingly to the diagram of the water supply.

For cross-flow system of installation an adequate mixing tap must be purchased. For the execution above sink is needed a mixing tap above sink, and for execution under the sink the mixing tap under the sink. Inlet of cold water is marked with blue colour and the outlet of hot water is marked with red colour. Upon the inlet pipe before the mixing tap it is mandatory to built-in a non-return valve preventing the running of water of the tank if the water in the network runs short. If the pressure in water supply network surpasses 5 bar, before the mixing tap also a reduction valve must be built in.

By choice of the cross-flow mixing tap, particular attention must be paid to the data of supplier about reduction of pressure by the resistance appearing by flow of water through the mixing tap. By entirely open outlet valve this must not surpass 0,2 bar. To the outlet pipe of mixing tap no device driven by water or spray nozzle may be connected, which could cause the increase of pressure in the tank of the water heater. If these instructions shall not be respected during the operation, a damage of the heater may occur.

Prior to the electric connection, the heater must be obligatorily filled with water. By first filling the faucet for the hot water upon the mixing tap must be opened. The heater is filled with water when the water starts to run through the outlet pipe of the mixing tap. If the heater at connection would not be filled with water, at first switching-on the damage of thermal fuse shall occur and the heater shall not operate at all.

CONNECTING THE WATER HEATER TO THE POWER SUPPLY NETWORK

Connection of the water heater to the electric network must be performed according to standards for electric installation. The heater shall be connected to electric power supply over an electric cable with plug. If the built-in cable shall be replaced with a new longer one, the built-in cable may be removed and the new connecting cable inserted where the cable wires shall be screwed to the connection terminal. In order to do this, the plastic lining of the water heater must be removed. This is done so that at first the plate is removed, inserted in the front side of the plastic lining. The plate is released so that in the slot between the inserted plate and the plastic lining at first at the thermostat knob and on the side in front of the knob cautiously a screwdriver is pushed in. When the plate is released at both sides, it can then be removed by hand. Then the thermostat knob is removed and the screw under the knob is unscrewed. At last also all four screws for fixing of plastic lining are unscrewed and the lining removed.

CAUTION: Before any intervention into the interior of the water heater, disconnect it from the power supply network! This intervention may only be performed by a trained professional!

After connecting to the water and power supply, the heater is ready for use. By turning the knob of thermostat at the front side of the protecting cover, the wished temperature of water 75 °C is chosen. We recommend the adjustment of the knob to the position "e". Such an adjustment is the most economic, with it the temperature of water shall be approximately 41 °C in case of TEG 0520 or 35 °C in case of TEG 1020, the excretion of lime-stone and thermal loss shall be smaller as by adjustment to higher temperature (poz. II - 55 °C in III - 75 °C).

The operation of electric immersion heaters is shown by pilot light which is lit during the time until the water in the heater is heating to the chosen temperature or to the intended switch off. During the heating the volume of water in the heater is increasing, which causes the dropping of water from the mixing valve. By strong squeezing of the mixing valve the dropping can not be stopped but the mixing valve can be damaged.

When the heater shall not be used during a longer time, its contents must be protected against freezing so that the electricity shall not be switched off, but the thermostat knob shall be adjusted to the position " * With this adjustment the heater shall maintain the water temperature by approximately 9 °C. But when the heater is switched-off the electric network, at risk for freezing, the water must be emptied from it. Water from the heater is drained through the inlet/outlet pipe of the heater.

The outside of the heater is cleaned with a mild solution of detergent. Solvents or rough cleaning means should not be used. Regular service checks shall ensure impeccable operation and a long lifetime for the heater. The first check must be performed by an authorized service workshop approximately two years after the first connection. At the check, if necessary, lime scale must be cleaned, which, with regard to the quality and temperature of the water used, accumulates inside the water heater. The service workshop shall, after the check, also recommend the date of the next check.

Never try to repair any possible faults of the heater yourself, but inform the nearest authorized service workshop about them.

CONNECTION TO THE WATER SUPPLY NETWORK

Under-sink model

CONNECTION TO THE WATER SUPPLY

The water heater is designed for a flow-through (non-pressure) connection system. This system allows water consumption at only one point of use. The connection must be made in accordance with the water supply connection diagram.

For the flow-through connection system, you must install a suitable mixing faucet. For installation above the sink, you need a flow-through faucet for above the sink, and for installation under the sink, a flow-through faucet for under the sink. The water inlet and outlet on the heater pipes are marked with colors. The cold water inlet is marked in blue, and the hot water outlet in red. On the inlet pipe before the mixing faucet, it is mandatory to install a non-return valve that prevents water from flowing out of the tank if there is no water in the network. If the pressure in the water supply network exceeds 5 bar, you must also install a pressure reducing valve before the mixing faucet. When choosing a flow-through mixing faucet, pay special attention to the manufacturer's data on pressure drops due to resistance that occur when water flows through the mixing faucet. With the outlet valve fully open, it must not exceed 0.2 bar. You must also not connect any water-powered device or water sprayer to the outlet pipe of the mixing faucet that could cause an increase in pressure in the heater tank. If you do not follow these instructions, damage to the water heater may occur during operation.

Before electrical connection, the water heater must be filled with water first! During the first filling, open the hot water tap. The water heater is full when water starts flowing from the spout of the mixing faucet. If you do not fill the water heater with water before connecting it, the thermal fuse will be damaged upon first activation and the water heater will not work at all.

ELECTRICAL CONNECTION

Connecting the water heater to the electrical mains must be done in accordance with electrical installation standards. The electrical installation must include a device for disconnecting all poles. Connect the water heater to the mains via the connection cable. If you want to replace the built-in cable with a new, longer one, you can remove the built-in cable and attach the new one to the cable gland, then tighten the cable wires into the terminal block. To do this, you must first remove the plastic casing of the water heater. You can do this by first removing the plate (applies to models with an inserted plate) that is inserted into the front of the plastic casing. Release the plate by inserting a screwdriver into the slot between the insert plate and the plastic casing, first near the thermostat knob, and then on the side opposite the knob, carefully prying it. Once the plate is released on both sides, you can remove it by hand. Then remove the thermostat knob and unscrew the screw underneath it. Finally, unscrew all the screws securing the plastic casing and remove the casing.

WARNING: Before any intervention inside the water heater, always disconnect it from the electrical mains! Intervention may only be carried out by a qualified professional!

USE AND MAINTENANCE

After connecting to the water supply and electrical mains, the water heater is ready for use. By turning the knob on the thermostat, which is on the front of the protective cover, you select the desired water temperature up to 75 °C. We recommend setting the knob to the "e" position. This setting is the most economical; with it, the water temperature will be approximately 41 °C for TEG 0520, or approximately 35 °C for TEG 1020, and limescale buildup and heat loss will be less than when set to a higher temperature (pos. II - 55 °C and III - 75 °C). The operation of the electric heating element is indicated by the indicator light, which stays on until the water in the heater reaches the selected temperature or until it is switched off by the thermostat. Due to heating, the volume of water in the heater increases, which causes dripping from the mixing faucet spout. You cannot prevent the dripping by tightening the handle on the mixing faucet; you may only damage the faucet.

If you do not intend to use the water heater for a longer period, protect its contents from freezing by not switching off the electricity, and set the thermostat button to the "*" position. At this setting, the water heater will maintain the water temperature at approximately 9 °C. If you disconnect the water heater from the power supply, you must drain the water from it due to the risk of freezing. The water from the water heater is drained through the inlet/outlet pipe of the water heater.

Clean the exterior of the water heater with mild liquid cleaning agents. Do not use thinners or abrasive cleaning agents.

Regular service inspections will ensure flawless operation and a long service life for the water heater. Have the first inspection carried out by an authorized service center approximately two years after connection. During the inspection, limescale is cleaned as needed, which accumulates inside the water heater depending on the quality, quantity, and temperature of the consumed water. After the inspection, the service center will recommend the date of the next check based on the determined condition.

Please do not repair any faults yourself; instead, notify the nearest service center.
