7. MAINTENANCE
All components in the SF
tank are maintenance-free for the
6
declared life expectancy of the product. The tank is made of
stainless steel.
If the panels substain any scratches or damage, these must be
repaired with paint to prevent corrosion.
Mechanical parts are positioned outside the tank and behind the
front panel. This enables easy access and replacement if
required.
Mechanical parts are surface-treated to prevent corrosion.
Moving parts are lubricated at the factory for the product's life
expectancy. In extreme conditions (dust, sand and pollution),
inspection and maintenance will be imperative, and in some
cases replacements will be necessary. Check that the lubricant
is not washed or wiped away from the mechanical moving parts.
7.1 CONTROL AND MONITORING THE GAS
SafeRing / SafePlus is a pressure-sealed system that normally
does not require special inspections. However the gas pressure
on the manometer should always be checked prior to
operation.
