DESCRIPTION AND PRINCIPLE OF OPERATION

The outside casing of the EWH is made of impact-resistant plastic. Inner tanks have a special bio-glass-porcelain coating reliably protecting the inner surface against chemical corrosion. The space between the outside casing and the inner tank is filled with polyurethane foam – a modern, ecologically clean thermal insulation, which has the best heat-saving characteristics. ID (shadow) models have two screwed nozzles: for inlet of cold water (Figure 1, p. 3) with a blue ring and for outlet of hot water (Figure 1, p. 2) — with a red ring, and equipped with an additional drain connection (closed with metal plug button) for draining the water and flushing the inner tank (Figure 1, p. 17). The control panel, in all models, is on the front side of the EWH. (Figure 1, p. 16).

Tubular heating element (THE), thermostat and thermal switch sensors are mounted on the removable flange. THE is used to heat water and thermostat provides with possibility of heating temperature regulation up to +65°. All models have electronic control with sensor adjustment. Electronics maintain automatically water temperature at the level set by the user. The thermostat is used for protecting against EWH overheating, which disconnects THE from power supply when water temperature exceeds 95°. (Fig. 3).

Safety valve (Fig. 1, p. 5) operates as the check valve, ensuring protection of the water ingress from the water heater into the sewage system in case of pressure drop in the sewage system and in case of pressure rise in the tank at high water heating, as well as the functions of the safety valve, releasing overpressure in the tank at high water heating. During water heater operation water may leak out of the exhaust outlet pipe of the safety valve to relieve excessive pressure, which is made for the purpose of water heater safety. This outlet pipe shall remain open to the atmosphere and be installed constantly down.

Drainage of water from the safety valve exhaust pipe into the drain shall be provided with installation of the corresponding EWH drainage.

It is required regularly (at least once a month) to discharge a small amount of water through the exhaust pipe of the safety valve into the drain to remove lime deposits and to test the operating functionality of the valve. Handle (Fig. 1, p. 15) is intended to open the valve. It is necessary to control when operating water heater this handle to be in position closing water draining from the tank.

SPECIFYING SECURITY MEASURES

Electrical safety and corrosion protection of EWH are guaranteed only if there is an effective grounding in accordance with applicable electric installation rules and regulations.
Plumbing pipes and fittings shall conform to parameters of water main and have the required certificates of quality.
When installing and operating EWH the following is not allowed:

• To power EWH if EWH is not filled with water.
• To remove the protective cover when the power is on.
• Use EWH without grounding or use water pipes as grounding.
• To connect EWH to water supply with pressure exceeding 0.7 MPa.
• To connect EWH to the water supply without safety valve.
• To drain water from EWH with power switched on.
• To use spare parts not recommended by the manufacturer.
• To use water from the EWH for cooking.
• To use water containing impurities (sand, small stones), which might lead to EWH and safety valve breakdown.
• To modify design and installation dimensions of EWH brackets.
  Ambient temperature shall be within the range of 3º to 40º. Water in freezing EWH at negative temperatures results in malfunction, which is not a warranty case.
  Attention should be paid to children so that they do not play with EWH. EWH is not intended for use by persons (including children) with limited physical, sensory or mental capabilities, or by persons who do not know how to use the EWH, except for cases when this happens under the supervision or instructions by persons responsible for safety of the EWH.
