Before the start-up close the draining connection e.g. by screwing the valve in and
make sure that the installation procedures have been carried out in accordance with the
regulations included in this manual. Cylinder must be filled with water:
-
turn on the valve on cold water supply pipe,
-
turn on the hot water outlet valve (water outflow without the air bubbles indicates
that the storage is full),
-
turn off the outlet valves.
Turn on the valves connecting cylinder with the central and the solar collector heating
system. Check for water and heating medium leaks. Check out the safety valve performance
in accordance with valve manufacturer’s instruction.
Follow the guidelines below for safety and trouble-free cylinder operation:
•
Check out the safety valve performance once every 14 days. Do not use the cylinder
if the water does not come out (it indicates that the valve is broken).
•
Clean inside of the cylinder periodically. The frequency of cleaning depends on the
degree of water hardness. The cleaning should be done by a qualified person.
Tightening torque value of access hole cover [21] screws must be 18-22Nm.
•
The wear condition of the anode must be inspected annually.
•
The anode must be replaced once every 18 months.
-
anode rod replacement [13]: take off the upper lid [16], take out an insulation ring,
turn off the cut-off valve on cold water supply pipe, turn on the hot water valve
(mixer tap), turn the drain valve on, drain as much water as you can easily screw
out the anode rod (avoiding room flooding), screw off the cork and screw out the
anode rod,
•
Heat up the water above 70°C periodically for hygiene reasons.
•
Failures or malfunctions notify to the seller.
•
Insulate the outlet pipe and heating coil connection pipes to minimise the heat loss
(recommended).
Above activities are beyond of the scope of warranty service (should be done by the user).
