the system connection to the water supply network and the tank is filled with water; during the
use of the tank not less frequently than once every 14 days; and after each stop of water
supply. It is therefore recommended that the combined valve be installed in an easily accessible
place. The use of the device with defective combined valve is strictly prohibited. Immediately
turn off the power supply of the water heater and contact the nearest authorized service center.
Otherwise, it will cause a default on the tank and possibly cause other damages.

10. Where necessary the safety valve may  serve for draining the water from the tank. The
procedure is as follow:
Switch  off  the  appliance  from  mains  with  the  optional  device  and  even  for  greater  safety
disconnect the fuse protecting phase circuit.
Close the cold water access to the unit – close the tab on pos. 4 of Fig. 12.
Open the hot water tab of the mixing tab or disconnect the hot water outlet pipe from the water
heater.
Lift up the combined valve lever and wait until water stops to run from the valve.
These steps secure complete draining of water from the tank. The operation may be carried out
only by qualified person because it requires disconnection of the appliance from mains and
removal of the flange water tank.

WARNING!

 

IT IS ABSOLUTELY PROHIBITED TO SWITCH ON POWER SUPPLY TO THE

SYSTEM WHEN THE WATER TANK IS PARTIALLY FILLED OR EMPTY OF WATER!

 

Before putting the system back in operation do not forget to fill the water tank with water –
please refer to section 

Water heater connection to the water supply network

.

WARNING!

 

When draining water all precaution for damages from outflow water must be put in

place.

11.  The  rules  concerning  prevention,  anode  replacement  and  cleaning  of  accumulated
limestone must be observed even after the end of the appliance warranty period.
12. When operating and maintaining the appliance pay special attention to protect the metal
plate with appliance data and manufacturer (serial) number. In case of accidental removal from
the appliance preserve it together with the warranty, because it is the only way to identify the
appliance you have bought.
13.  

WARNING!

 Until the end of the warranty period it is compulsory each year to carry out

preventive services for the appliance – its main units and systems, which are performed by the
organization or the persons who have completed the installation. Failure to comply with this
instruction shall void the appliance warranty.

COMPLIANCE  WITH  THE  REQUIREMENTS  OF  THIS  INSTRUCTION  MANUAL  IS  A
PREREQUISITE FOR SAFE OPERATION OF YOUR PURCHASED PRODUCT AND IS ONE
OF THE WARRANTY CONDITIONS.
IT IS ABSOLUTELY PROHIBITED TO THE USER OR ANY AUTHORIZED BY HIM PERSON
TO UNDERTAKE ANY CHANGES IN THE PRODUCT DESIGN AND STRUCTURE. FINDINGS
OF  SUCH  ACTIONS  SHALL  AUTOMATICALLY  TERMINATE  THE  MANUFACTURER  OR
DEALER WARRANTY LIABILITIES.
WHEN  SERVICE  IS  NEEDED  SEEK  ONLY  MANUFACTURER  AUTHORIZED  SERVICE
COMPANIES LISTED IN THE ANNEXED FORM.
THE MANUFACTURER KEEPS HIS RIGHT TO STRUCTURAL CHANGES WITHOUT NOTICE
WHERE SUCH CHANGES SHALL NOT AFFECT PRODUCT SAFETY.
