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. Rif 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. The control knob, in all models, is on the front side of the EWH
(Figure 1, p. 12).
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 +75°С.
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 wa-
ter 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 in-
stalled constantly 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 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.
