1- GENERAL INFORMATION ABOUT WATER HEATERS

Safety: Each part of the water heater is checked carefully to provide excellent operation durability. Electrical circuit is
completely insulated from the water circuit. All models are equipped with at least 3 safety equipments.

Ease of use: All models can easily be mounted at any place.

Low heat loss: It is preferred to position water heaters that can be installed anywhere as close to the hot water source

as possible to keep the heat loss in the piping minimum.

Small amount of hot water: In order to avoid unnecessary energy consumption, models with different capacities are
designed for spaces such as kitchen or service room where small amounts yet continuously running hot water is
needed.

2- PROPERTIES OF THE WATER HEATER

2-1 Efficient insulation, low energy consumption

High density, thick polyurethane foam layer offer excellent insulation in all electrical heaters and reduces energy
consumption significantly.

2-2 Drum with long service life

Special process of enameling that protects the tank against corrosive (abrasive) effects of the water and water-soluble
substances. It provides longevity and reliability for the mentioned protection drums.

2-3 Magnesium anode.

By using more magnesium anodes in the products, an electro-chemical anti-corrosive system that prolongs the service
life of the drum is used. In addition, it is positioned to allow easy access to anode drum for control and part
replacement when required.

2-4 High quality heating elements.

Heating coils are manufactured using first-class material to ensure long service life.

2-5 Water temperature control

Products are equipped with a temperature control button that helps to maintain the temperature between 35°C and
85°C. Thanks to this button, every user can select the appropriate water temperature according to requirements and

hence achieve energy savings.

2-6 Thermostat.

Hot water heaters are equipped whit thermostats which guarantee high performance and maximum safety. The
electronic card assumes the function of the thermostat in electronic models.

2-7 Limit thermostat.

Hot water heaters are equipped with "maximum temperature" thermostat. This safety device deactivates the main
thermostat and heating coils in case of a failure.

2-8 Pressure safety.

Water heaters are equipped with a certified safety valve in terms of pressure values standards. Without the need to
remove discharge pipe, a check-valve is used to drain the unit when required.

2-9 Freezing Safety.

When water temperature in your water heater falls below 5°C, heating resistance is automatically activated and heats
the water up to 16°C. In the meantime, lamps with anti ice and heating coil signs illuminate and indicate the

temperature of the water. The anti-freeze safety system activates while the water heater is in stand-by. Install the
water heater in a location safe from risk of freezing. “This safety system is only available in electronically controlled
models.”

2-10 Bacteria Prevention System.

Researches show that when the water is kept under below 60°C for a long time it will become suitable for bacteria
growth. While the device in stand-by, to prevent bacteria from growing the water is heated at least once a week above
65°C and kept at this level for 1 hour. “This safety system is only available in electronically controlled models.”

2-11 Dry Operation Safety.

If your device is operating without water for any reason whatsoever, the system will be activated automatically and
generate E3 error code in the display. In this case disconnect the device using V-automated switch and ensure that the
water heater is filled with water. After ensuring that it is filled with water reconnect to the mains supply, the water
heater will commence its normal operation. “This safety system is only available in electronically controlled models.”

2-12 Low Voltage Protection.

If voltage is dropped to a level harmful for the device due to mains fluctuations, then the low voltage safety system is
activated and E2 error code is displayed. After the voltage is restored to desired level E2 error will disappear and the
water heater will commence its normal operation. “This safety system is only available in electronically controlled
models.”
