Trouble Shooting
Cause
Solution
Replace the O-ring on the overflow pipe or ensure
that the connection between the overflow pipe and
water intake pipe is below the water surface level
of the tank.
Remove the filter media from the containers and
clean them with tank water taken from the tank
Do not place the filter media in nets or nylon
stockings. Doing so may cause clogging, which in
turn may block the water flow
Check whether the hoses are connected properly
Leaving the power on, shake the unit to help
remove remaining air
Apply ample vaseline to all of the O-rings
Press the "start" button and repeat procedure
from the beginning
Ensure that the top of the motor is at least 10cm
below water level (see recommendations)
Remove and replace the plug in the socket 3-4
times Gently shake the filter to remove remaining
air
Please consult place of purchase
Due to breathing of bacteria and photosynthesis of
water plants, air bubbles may accumulate and
sounds of it being let out from the Tetratec
Filter may be heard. Corrective measures are not
necessary.
The motor is cooled by water hence if water in the
drive system is dirty or dirt is allowed to
accumulate, water flow will be inhibited and life of
the motor will be decreased. Periodically clean the
impeller/drive magnet and the surrounding area
under warm water.
Do not press the "start" button or put anything on
top of it while the filter is running
