TECHNICAL DESCRIPTION

The water heater is intended for use only for domestic purposes in the household and is used to heat water from a common water supply network, which composition and features comply with the specified values in water quality legislation. The water heater is connected to the general water supply network and provides hot water for washing only on the spot (sink) where it is installed. The water is heated at the time of flowing through the unit water tank.

There are three main models of water heaters each with two modifications:

• Model Е41 – with mixer tap with two handles and 3,5kW power
• Model Е42 – with ceramic mixer tap with one handle and 3,5kW power
• Model Е51 – with mixer tap with two handles and 5kW power
• Model Е52 – with ceramic mixer tap with one handle and 5kW power
• Model Е71 – with mixer tap with two handles and 6,5kW power
• Model Е72 – with ceramic mixer tap with one handle and 6.5kW power

On Fig. 1 is displayed the general view of water heater model E41.
The manufacturer reserves the right to change the general appearance and fittings while maintaining the appliance’s safety and functionality.

WATER HEATER CONNECTION TO THE WATER SUPPLY NETWORK

The installation of the heater and mixing tap is carried out in the following sequence – please refer to Fig. 1:

• The mixing tap (2) is screwed into the socket of cold water plumbing (3). The socket is not supplied with the delivery package. In order to ensure connection tightness may be used Teflon tape or another suitable substitute. For tightening use a suitable tap slot wrench. Once tightening and connection tightening is completed, the tap should be placed in a horizontal position so that after heater installation, the latter is in a vertical position with the pipes down.

• To the mixing, the tap outlet is mounted ONLY the winch (1)  s u p p l I e d I n t h e d e l I v e r y s e t .
  WARNING! Violating this requirement shall impede the appliance’s safety and functionality.

• Unscrew the nuts 3/8″(5) from the tap and take out the seals (4).

• Remove the two transport caps placed on the inlet/outlet pipes (6,7).

• Place the nuts on the water heater pipes (5) and then the seals (4).

• Take the water heater in your hands and carefully match its pipes in the mixing tap apertures. The water heater pipes must touch the mixing tap apertures bottoms. The pipe with the arrow pointing to the appliance must be on the right, while the one with the arrow pointing to the tap – on the left.

• While holding the water heater with one hand turn with the other the 3/8″ nuts to the tap. Be careful with the correct and uniform entry of the seals.

• Tighten carefully the nuts 3/8″ with a wrench. Pay attention not to over-tighten the connections.

WARNING! It is forbidden to install a different mixing tap than the one supplied in the manufacturer package.
WARNING! It is prohibited to install on the tap (8) output any fittings or plumbing parts other than the provided by the manufacturer winch or mixing tap!
Fill the water heater tank with water rotating the red tap (the one on the right) counterclockwise until the end (for the two handles tap models) or turn the handle right and upward (for ceramic tap models). Wait until the winch starts to flow strong and solid water flows. Then close the red tap by rotating clockwise to the end (for two handles tap models) or turn the handle down (for ceramic tap models). Because the appliance is with an open-air outlet (the water tank is permanently connected with the atmosphere through its outlet pipe), when the knob is rotated it is possible that from the winch flows out some water until the tank outlet system is completely empty. This is not a defect and the quantity of outflowing water is minimal.
WARNING! Failure to fill the water tank shall cause damage to the water heater.
WARNING! Failure to comply with these instructions and their consequences are not covered by manufacturer or seller warranty liabilities and shall be at the expense of the party, which has not observed the present manual instructions.

WATER HEATER CONNECTION TO THE POWER SUPPLY NETWORK

The instantaneous water heaters have an electrocution degree of protection Class I.
The main circuit to which the appliance is connected must be three-wire: phase, neutral, and grounding conductors. All the extremities of wires in the appliance circuit must be properly connected to the main power switchboard and in the point of connection of the water heater to the power supply grid. The installation grounding conductor must not be interrupted at any place on its route from the appliance to the main power switchboard. The cross-section of the circuit conductors and the fuse size are discussed below. The electric installation to which the heater will be connected must be built in accordance with the requirements of the applicable statutes and local regulations in force.
Models E41 and E42 come factory connected to the appliance with power cord and plug type Schuco. The unit connection is carried out by plugging the power cord into an upright and properly connected contact with protective plates type Schuco. The socket must be located in a place where it is secured against any spraying or pouring liquid, from the condensation of moisture on it and the plug joined and to be easily accessible after installing the heater in its working position. The conductors of the electric 2 installations must be with cross-sections at least 2.5 mm each. The fuse in the phase circuit must be 16 A.

The models E51, E52, E71, and E72 come with a factory connected to the unit three-wire power cord.

• The cross-section of each of the wires in the power cord models E51 and E52 is 2,5 mm².

• The cross-section of each of the wires in the power cord models E71 and E72 is 4 mm².

• Connect the power cord wire ends to a socket of the premise power supply circuit. The socket location must be selected so that it can be protected from any spraying or pouring liquid, from condensation or moisture on it and on the connecting power cord.

• The premise’s electric installation conductors which power water heaters models E51 and E52 should be at least with a section 2,5 mm each and provided with phase fuse circuit – 25 A.

• The premise’s electric installation conductors which power water heaters models E71 and E72 should be at least with a section 4 mm each and provided with phase fuse circuit – 35 A.
  WARNING! IT IS IMPERATIVE that the power cord wires connecting the tank to the installation socket be as follows:

• brown wire cord to the electric installation phase conductor;

• blue wire cord to the electric installation neutral conductor;

• green-yellow wire cord to the electric installation protective grounding conductor (grounded circuit).
  WARNING! IT IS COMPULSORY that in the premise electric circuit feeding the heaters models E51, E52, E71, and E72 is installed such a device, which in the conditions of overvoltage category III, provides complete disconnection of all poles. The conductors between the circuit and the device incoming
  electrical terminals must not be interrupted by any circuit breaker or fuse.
  WARNING! When connecting the water heater to the mains the proper connection to the electric installation neutral and protective conductor is compulsory. Failure to comply shall make the appliance dangerous and in such a state, its use is strictly forbidden!
  WARNING! Failure to comply with the requirements concerning connection to the mains shall reduce the appliance safety, which it is prohibited to use. Such consequences are not within the scope of manufacturer or seller warranty liabilities and shall be at the expense of the party, which has violated the present manual instructions.

The electric installation inspection and the connection of the water heater can be carried out only by authorized persons.
Once the water heater is installed and connected properly with water and electric supply networks it should be put into operation and tested for functionality. Appliance installation, connection, and functionality tests must be performed only by a qualified person. These activities are not manufacturer or dealer warranty obligations and are not covered by warranty service.

HOW TO USE THE APPLIANCE

The water heater can be switched in operation ONLY after being filled with water. CHECK! The check shall be carried out with heaters off (the extremities of the key marked “0” are pressed) the red tap of the mixing tap is turned counterclockwise (open position for two handles tap models) or turn the handle right and upward (for ceramic tap models). Wait until a dense water stream flows.
WARNING! If the winch (the shower apertures) do not leak water it is likely that these are blocked. In such case the device use is prohibited – please refer to the section Maintenance and prevention.
WARNING! Do never switch the appliance if there is a chance that the water in the water tank is frozen! This shall damage both heater and the tank.
Switching in operative mode the appliance filled with water and connected to the electric installation is carried out by opening the red tap of mixer tap with two handles or by rotating right and upward the handle of ceramic tap:

• When the key is switched off (the extremity marked “0” is pressed) from the winch (shower) shall flow cold water.
• When the key is switched on (the extremity of the key marked I and/or II is pressed) when rotating the knob after reaching a certain water flow, the key indicator lamp shall light up and the heater will turn on. The water temperature stabilizes after about 15-30 s.
• With the key in ON position turning the red tap of mixer tap with two handles in either direction or by turning right or left, and raising or lowering the handle of ceramic tap serves for selecting the optimum water temperature.

NOTE! To adjust the water temperature we recommend using only the red crane. At low water flow, the temperature is high and at higher flow rates the temperature lowers. The blue tap is used mostly for cold water.
For water heaters models E51, E52, E71, and E72 the water temperature can be further adjusted by switching on one or both of the heaters using the two- buttons key (marks “I” and “II” on the buttons). The button marked “I “switches the heater unit – the one with greater power.
The button marked “II” switches on the booster heater serving to increase the overall capacity of the unit. If only the booster heater is switched on, it is possible that the desired temperature of heated water is not achieved. Within the water heaters is built-in a thermal limiter to prevent water temperature excess beyond a specific limit.
When the water temperature reaches such a limit, the limiter switches off the heaters and then once the temperature falls too low switches them on.
For all water heater models, it may occur a significant decrease of the water flow through the unit that the integrated hydraulic breaker disconnects the heaters. Once the water flow increases the heaters shall be switched on.
Once the use of hot water is completed, close the red tap, switch the key/button in position “0” and wait for the water from the winch to drain out.

UNIT MAINTENANCE AND PREVENTION

The device is equipped with an integrated special valve protecting its structure from any hazardous pressure increase in the water tank.
In such cases the valve membrane is torn-off and the discharge pipe valve starts leaking. The safety valve pipe outlet is left of the appliance pipes – Fig. 2.

WARNING! IT IS PROHIBITED to clog the opening of the safety valve pipe!
When water leaks from the safety valve pipe nozzle it is MANDATORY immediately to:

• Stop using the device by closing the red tap (stop water flow through the unit);
• Toggle the buttons of the key in switch off position (the extremities of the key marked “0” are pressed);
• Switch off the unit from mains:
• for models Е41 and Е42 unplug the power cord from the socket;
• for models Е51, Е52, Е71 and Е72 switch off the additional switch;
  • Contact the nearest authorized by the manufacturer service company.

To protect the appliance in areas with high limestone content in the water we recommend cleaning limestone deposits on heaters from time to time. This can be carried out only by authorized by manufacturer repair specialists because it requires unit disassembly. This service is not part of manufacturer warranty liabilities.
In case of doubts for temperatures below zero in the premise where the appliance is installed, the water must be drained off.
This is carried out with the tank disconnected from the mixing knob with interrupted access of water from the water supply, held for a while in a vertical position with the pipe down, and waiting until the water is completely drained from the unit water tank.
WARNING! When draining the water out of the water tank all necessary precautions must be taken to prevent damages from flowing out water.
If the unit inlet pipe does not leak water you should contact the nearest authorized service center to remove the particles clogging the system (most frequently limestone).
Increasing the water pressure in the water tank of the appliance is a result of non-compliance with the appliance installation and usage requirements – mounting the appliance to operate under pressure, blocking the hot water pipe outlet, irregular cleaning of the limestone deposited in the areas with limewater, water freezing, etc. Replacing the safety valve membrane is not a warranty obligation of the trader and/or manufacturer.

FAILURES

In cases when the heater does not heat water, check if it is correctly connected to the mains, or if the power supply in the premise is not cut off, or if the illuminated switch is not in position off, or if the water flowing through the appliance is too little, or if the pressure in the plumbing is not lower than necessary.
If none of the above listed possible causes is present, disconnect the heater from the power supply, stop the water flow to the appliance, and call the nearest authorized service company.
In case that with a normal water supply and the knob turned to its maximum position and switched on the power supply (mains and unit key illuminated) from the winch or the shower apertures is leaking water, and key buttons are glowing, IMMEDIATELY UNPLUG THE APPLIANCE from both the power and the water supply networks.
IT IS FORBIDDEN to attempt appliance subsequent switch on. Immediately contact the nearest authorized by the manufacturer service company.
In case of failure of the power cord and plug of water heater models  “E41” and “E42”, contact the nearest authorized by the manufacturer service company as the cord with plug must be replaced by the manufacturer, its service agent, or a person with similar qualifications in order to avoid danger.
During the appliance usage and maintenance do not damage the metal plate with its technical data and serial number. If you take it from the appliance store it is together with the warranty card because this is the only way to identify the product you purchased.
