The outside casing of the EWH is made of steel. 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 char-
acteristics. TTVER models have two screwed nozzles: for inlet of cold water (Fig. 1, p.
3) with a blue ring and for outlet of hot water (Fig. 1, p. 2) — with a red ring. The
control panel, in all models, is on the front side of the EWH. (Fig. 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 pos-
sibility of heating temperature regulation up to +80°С. All models are controlled with
electronic monitoring panel. Electronics maintain automatically water temperature at
the level set by the user. The thermostat is used for protecting against EWH overheating,
which disconnects TEH from power supply when water temperature exceeds 95°С.
(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 con-
stantly down.
Drainage of water from the safety valve exhaust pipe into the drain shall be pro-
vided 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.
