Test kit
The basic maintenance tasks must be performed by
trained users.
The advanced maintenance tasks must only be
performed by certified service persons.
Shut down the whole system before any work on the
system components and lines.
Separate the system from the power supply before
any work on the system components and lines.
Wear the stipulated personal protective equipment
(protective clothing, goggles, respirator etc.).
Observe the chemical manufacturer's safety data
sheets (MSDS) and safety instructions of the used
chemicals.
Safety installations, which have been disabled or
removed during maintenance, must be enabled or
installed again immediately after maintenance.
Before starting any work in the ATEX zone, stop the
Selcoperm system and wait until the degassing fan
stops.
WARNING
Electric shock
Death or serious personal injury
Liquids on electrical components can lead to electric
shock. Furthermore damage to the equipment can be
caused by short circuits.
- Keep all electrical components dry.
- Cover electrical components during maintenance
with a watertight foil.
CAUTION
Chemical hazard
Minor or moderate personal injury
Sodium hypochlorite solution tends to emit chlorine
gas.
- When working with open tanks or lines, wear
appropriate personal protective equipment.
When the Selcoperm system is stopped via the
control panel or via external contact, the degassing
fan continues running for some minutes. This
ensures the removal of residual hydrogen gas from
the system, lines and degassing and storage tank.
Wait until the degassing fan stops before starting any
work on the system, lines and degassing and storage
tank.
If the power supply was switched off or in case of
power failure, wait at least 20 minutes before starting
any work on the system, lines and degassing and
storage tank.
Rinse removed parts with clean water.
Before reassembling make sure, that all parts are
clean, dry and undamaged.
