13 Cleaning the storage cylinder and dismantling the internal components
OUTSIDE
Cleaning the cover of the storage cylinder should be car-
ried out with damp cloths and water and soap. In the
case of stubborn stains dampen the cloth with a mix-
ture of 50% water and methylated spirit or with specific
products for the marks. Once the cleaning is finished, dry
the storage cylinder.
Do not use abrasive products, gasoline or trichloro-
ethylene.
INSIDE
Removing and checking the magnesium anodes
First magnesium anode:
- Remove the plug (1), the cover (2) and, with a wrench,
unscrew the anode-carrying plug (3)
Second magnesium anode:
- Partially remove the cover (4) and, with a wrench, un-
screw the anode-carrying plug (5)
Check the state of wear of the magnesium anode and
replace it if necessary.
Once the cleaning operations are finished, reassemble all
the components, following the above instructions in the
reverse order.
NOTE:
the tightening torque of the anode-carrying plug
should be 25-30 Nxm.
Cleaning the parts inside the storage cylinder
- Remove the flange cover (6)
- Unscrew the bolts (7), remove the cover (8) and the
gasket (9).
- Clean the inside surfaces and remove the residues
through the opening.
Once the cleaning operations are finished, reassemble all
the components, following the above instructions in the
reverse order.
Tighten the bolts (7) with a "cross-head" system to
uniformly distribute pressure on the gasket.
- Load the storage cylinder's secondary circuit and check
the seal of the gaskets.
- Carry out a performance test.
14 Recycling/disposal
When they are no longer needed, the components of the solar storage cylinder (boiler body, insulation and outer cover)
can be separated from one another and disposed of using the most environmentally compatible recycling procedure.
