Figure 12 Insulation of the pipes
mA
●
Insulate pipes: continue pipe insulation into the re-
spective openings in the ratchet closure to avoid heat
loss at the entering points (fig 12)
6 Troubleshooting
The flat sealing gaskets may change their density during
the first few months of operation This normal settling
behavior may occasionally lead to dripping The connec-
tions should therefore re-tightened as required
7 Maintenance
The cleaning and maintenance of the solar storage tank
should be carried out every two years together with the
maintenance of the solar installation We recommend a
service contract
●
Defunct protective anode leads to corrosion of the
storage
tank!
Over time the built-in protective sacrificial anode is con-
sumed during operation Check the protective anode af-
ter two years, and afterwards annually
- Remove the build in uninsulated sacrificial magne-
sium anode, examine remaining magnesium mass and,
if necessary, install new anode
- For sacrificial anodes with insulated installation (MG an-
odes) test the protective current between storage and
anode (fig 13) When the value is below 0 3 mA, remove
and examine the anode and replace if required
- If an impressed current anode is installed, observe the
related product documentation A green light signals
correct function
●
Check for visible leakage of the fittings If necessary
retighten fittings
●
The proper function of the safety valve regularly has to
be tested The blow-off opening must never be closed
or obstructed
●
Required cleaning of the storage tank can be carried
out through the access/cleaning flange Install new
gasket when closing!
Regular maintenance must be certified in the Mainte-
nance Protocol by a qualified person in order to render
the warranty agreement valid
8 Disassembly and Recycling
At the end of the long operational lifetime, the valu-
able materials of the installation should be recycled in
an environmentally sound manner
