GB
Ensure that the unit is placed at a flood protected place and on firm ground. Keep a minimum distance from the
pond edge of 2 m. Ensure unrestricted access to the cover to be able to carry out work on the unit. (A1)
Push or turn the hose onto the stepped hose adapter, secure with a hose clip, then screw the stepped hose
adapter on the water inlet (A2).
Ensure that the drain pipes for the water return (A4) are laid towards the pond with a suitable incline (>1 %).
Tetra recommends to return the clean water into the pond via a water course to additionally enrich the water
with oxygen.
An optional adapter set is available for the cleaning outlet (A3). For this purpose, remove the cover cap from
the cleaning outlet. Push the union nut over the hose, slide the stepped hose adapter without thread onto the
hose end and secure with the hose clip. Connect the stepped hose adapter with union nut and flat seal to the
cleaning outlet. Push the stepped hose adapter with thread onto the other hose end, secure with the hose clip
and screw on the cover cap including flat seal. Lay the hose with a suitable incline (>1 %) towards the sewage
system or to a flower bed.
Start-up (B)
Important: Adhere to the safety information given above! Check the correct seating of hoses and cover cap
prior to starting up. Never operate the UVC clarifying unit without water.
Switch on the pump and wait until the filter housing is filled with water. Check all connections for leaks.
Connect the power plug of the UVC clarifying unit, the blue control lamp is lit. In the event of overheating, the
temperature monitor switches the UVC clarifying unit off automatically. The UVC clarifying unit automatically
switches on again once it has cooled down.
Note: After a new installation, the unit only reaches its full biological cleaning effect after a few weeks, and is
most efficient at temperatures above 10 °C. This corresponds to increases in fish activity in warmer water.
Switch the UVC clarifying unit off.
Disconnect the power supply to switch off the unit.
Maintenance and cleaning
Attention! Always disconnect the power plug from the UVC clarifying unit (C1) prior to starting cleaning and
maintenance work!
Adhere to the safety information given above! Check and clean the water outlet to the pond at regular intervals.
Clean the filters at regular intervals (e.g. every four weeks), however, at the latest when cloudy or dirty water
from the water outlet returns to the pond. Carry out quick cleaning first. Should this prove insufficient, clean the
entire unit. Never use chemical cleaning agents.
Quick cleaning (C2, C3)
Open and remove the filter lid from the filter housing (C2). Pull the cleaning handles several times (C3). This
causes the foam filters to compress and be mechanically cleaned. Open the cover cap at the cleaning outlet
and drain the soiled water. Screw the cover cap back on again and start the unit up (see Start­up).
Complete cleaning (C2 – C5)
Open and remove the filter lid from the filter housing (C2). Unlock and remove the inner cover (C4). Press both
engagement hooks at each of the foam filter holders sideward, then remove holders including foam filters (C5).
Remove the foam filters from the holders and clean with pond water. Open the cover cap at the cleaning outlet
and clean filter housing, inner lid and cover with water. Reassemble the filter in the reverse order. Arrange the
foam filters in water flow direction: Coarse foam filters (blue) first, then fine foam filters (red). Screw the cover
cap back on again and start the unit up (see Start­up).
Cleaning the UVC clarifying unit (D)
Open and remove the filter lid from the filter housing (C2). Turn the unit head of the UVC clarifying unit counter­
clockwise against the stop, then carefully pull off (D1). Undo the clamping screw by turning counter­clockwise,
and move the quartz glass including the O ring forward with a slight turning movement (D2). Remove the O ring
from the quartz glass, clean and check for damage. Clean the quartz glass outer face with a moist cloth and
check for damage. Thoroughly clean the inner and outer surfaces of the housing. If necessary, replace the UVC
lamp (D3).
Reassembly: Push the O ring against the collar of the quartz glass, press the quartz glass into the unit head
against the stop, fit the clamping screw and hand­tighten (D4). Check the O ring at the unit head for damage, fit
