CAUTION
Soft soldering is not authorized.
The use of flux promotes corrosion conditions in systems
operating with propylene glycol as heat transfer fluid. In all
cases the inside of the pipes must be flushed.
CAUTION
To protect the insulation against mechanical damage, bird
picking and UV light, add extra protection for the heat
insulation sleeves in the roof area by using an aluminium
sheet sleeve or aluminium adhesive tape. This additional
protection must be sealed with silicone.
