3.5.1.
At battery discharge
it is necessary to install new batteries (2 pcs.) of dimension-type D into the battery sec-
tion 14 (see scheme 14), in accordance with polarity, indicated on the internal side of the section
’s coverplate. He indica-
tor of battery discharge is the absence or a sustainable reduction of electric sparks
between the ignition plug and burner after the beginning of water flow through the appli-
ance (with consumption not less than 2,5 l/min). In order to open the battery section
’s
coverplate it is necessary to turn the coverplate’s knob into the position «ОN». In order
to take the discharged elements out it is necessary to unbend the holddowns (shown
with arrows on scheme 15).
It is recommended to install alkaline batteries of the type LR20, of increased energy
output ratio, providing longer operation time of the appliance. Installation of low quality
batteries or of batteries with low energy output ratio will lead to their rapid discharge and
loss of the appliance’s function. After installing the batteries it is necessary to close the
section’s coverplate and turn the coverplate’s knob to the position «ОFF».
3.5.2. Battery replacement must be effectuated on the appliance when it is
switched off.
3.6. Protection from freezing
In case if after switching the appliance off water freezing is possible in it, it is necessary to drain the water out of the
appliance in the following way:
а) Close the gas lock valve and cold water lock valve by the inlet into the appliance;
b) Open the hot water tap;
c)Switch the water consumption regulation knob to the position
“Maximum consumption”, turn the plug 20 (scheme
12, 14), let the water drain to a tank and turn back the plug 20 up to the stop;
d)close the hot water tap.
3.7. Actions in emergency situations
In case of emergency situation during the appliance
’s operation it is necessary to:
a) Close the gas stop valve by the inlet into the appliance;
b) Close the cold water stop valve by the inlet into the appliance (in case of water leakage appearance);
c) Call the special service organization for the
appliance’s repair.
ATTENTION! At switching the appliance off by the draught sensor (thermorelay 16, scheme 12, 14) it is nec-
essary to close the hot water tap and ventilate the premise. Switching the appliance on the next time would be
possible after thermorelay’s self-cooling (in 1-2 minutes). In case of repeated shutdowns of the appliance by the
draught sensor it is necessary to address to a specialized service organization in order to eliminate the failure of
the gas outlet system. Switching the draught sensor off and incompetent handling of it is unacceptable and can
cause poisoning with carbonic oxide.
