3.1 Start-up
The hydronic back-up boiler (see Figure 5) and solar storage
tank (see Figures 4 & 5), constitute a functional unit. Hot water is
generated throughout the year by the solar collectors (see Figure 4).
Supplemental heat is provided by the back-up boiler when there is
insuffi cient solar energy available (see Figure 5).
The entire heater and hot water system must be fi lled with water
and have adaquate air ventilation. Please refer to the solar
collector’s and the boiler’s installation instructions.
3. OPERATION AND SERVICE
4. MAINTENANCE AND CLEANING
Routine care and maintenance extends the life expectancy and
operating safety of the hot water storage unit. The outer casing
should be cleaned with a slightly damp cloth and commercially
available neutral cleaning agent. This should be done on a regular
basis.
4.1 Temperature / Pressure Relief Valve

WARNING: THE T&P RELIEF VALVE IS DESIGNED TO RELIEVE BUILT
UP PRESSURE IN THE WATER HEATER. FLUID MAY BE DISCHARGED
AT HIGH TEMPERATURE AND/OR PRESSURE. SCALDING HOT WATER
INJURIES CAN OCCUR.
NOTICE: THE WATER HEATER AND T&P RELIEF VALVE SHOULD BE
INSTALLED AND PIPED IN AND TO AN AREA WHERE WATER DISCHARGE
AND LEAKING WILL NOT CAUSE PROPERTY DAMAGE.
The proper function of the Temperature / Pressure (“T&P”) relief
valve is required to prevent damage to the hot water storage unit.
The T&P valve needs to be open during cold-water addition. The
water has to fl ow from the relief line at full stream.
4.2 Decalcifi cation
With hard tap water, a deposit of scale will form on the inside of
the storage unit. Based on professional experience, it is necessary
to decalcify with commercially available solvents at timely intervals.
Follow the manufacturers instructions for solvent use. The hot water
storage unit needs to be emptied. The inspection cover must be
removed and sediments on the tank bottom must be fl ushed.
4.3 Replacement of the Sacrifi cial Anode
Depending on the composition of the tap water, an inspection
of the sacrifi cial anode (Pos. 1, Figure 1) at timely intervals is
recommended. With heavy wear, an original equipment replacement
anode must be installed to protect the inner container from
corrosion. An inspection should be performed at least once a year.
