EWH is turned on/off by turning the indicator line on the control knob to the
"on/off" zone. During operation of EWH, the user can adjust the heating temperature
by turning the indicator line on the control knob to the "low", "eco", "max" zones on
the control panel, which set different heating temperatures ("min" - minimum, temper-
ature "eco" mode - the most economical, preventing the formation of bacteria and scale,
"max" - maximum) when the indicator line located on the control knob is switched to
them.
The control lamp "Heating" (Fig. 2, p. 2) lights up when the water is heated and
goes out when the set temperature is reached.
When performing maintenance scale on THE is checked. At the same time residue
that may accumulate in the bottom of the EWH is removed. If there is scale on THE, it
can be removed by using scale removing means or mechanically. It is recommended to
hold the first technical maintenance after a year from the time of connection by experts
of a specialized organization and depending on intensity of scale and residue to deter-
mine intervals of follow-up maintenance. This action will extend the maximum EWH
service life.
The first replacement of the magnesium anode shall be made no later than 12
months from the date of EWH installation. In case of no mark of installation in warranty
certificate with the seal of installation company, the period is calculated from the date
of purchase. Regular periodic maintenance and annual replacement of the magnesium
anode in time is imperative to maintain the manufacturer's warranty. Replacement of
the anode must be accompanied by a mark in the warranty card in case of replacement
by a service organization, or an attached sales receipt for its purchase in case of replace-
ment by the owner.
