Safety Precautions; Troubleshooting - Sera UV-C 24 W Handbuch

SAFETY PRECAUTIONS

• Please make sure the frequency and the voltage of the
mains supply equal those on the type plate before
using the unit.
• Caution! Strong UV-C lamp! Unprotected contact of
eyes and skin with the UV-C light leads to severe eye
damage and skin burns (strong sunburn) within a short
time (20 – 30 seconds).
• Strong UV light is emitted while the UV-C lamp is in
operation. Do not look directly into the UV-C lamp,
otherwise it may injure your eyes and your skin.
• The special sera UV-C lamp may be operated only
inside the undamaged sera UV-C System 24 W after
it has been completely assembled according to these
directions for use. Every other use may lead to skin
and eye damage!
• Always keep UV units and UV-C lamps out of the
reach of children!
• All electrical units in and around the aquarium and
pond must be disconnected from the power/mains
supply before conducting work at/in the pond and on
the sera UV-C System 24 W.
• Operate unit only with an inserted fault current protec-
tion switch (RCD or FI with a trip current of 30 mA).

Troubleshooting

Problem
UV-C lamp is not on
Cloudiness/Algae remain
unaffected
No water flow
Possible cause
Cable connections are not plugged in
properly
UV-C lamp faulty/too old
UV-C lamp has no contact
Ballast faulty
No bacterial cause, mineral cloudiness
UV-C lamp faulty/too old
Water flow too high
Pump is not switched on
UV-C system clogged
Too much height difference
• Do not operate if unit is submerged!
• Do not operate the UV-C system without water flow!
• Ensure that there is sufficient water flow through the
sera UV-C System before switching on the UV-C
lamp. A minimum flow rate [approx. 200 l/h (53 US
gal./h)] must be ensured during operation.
• Usage in or at swimming pools, walk-in ponds or
swimming ponds is not permitted!
• In case of possible frost, disconnect and drain the
sera UV-C System 24 W, and store in a frost-free
location (without water or water remainders). We rec-
ommend thoroughly cleaning and lubricating all seal-
ing rings before winter storage.
• Frequent "ON/OFF" switching reduces the life
expectancy of the UV-C lamp.
• Ensure that the electrical plug of the switched-on unit
is freely accessible at all times.
• Do not lift nor carry electric devices by their mains
cord.
• Although the unit is suitable for permanent operation
we recommend that you do not use it for more than
72 hours without interruption.
Possible solution
Check connections
Replace lamp unit
Push UV-C lamp properly into
the fixture
Let an expert replace the ballast
Use a fine filter, water change
Replace lamp unit
Reduce water flow
Switch on
Cleanse
Place the UV-C system in a lower
position
