WilTec pond filter functions
The
WilTec pond filter clarifies the water in 3 phases:
1. The first stage is
mechanic.
The visible particles of dirt are removed by means of a 3-layer filter
foam, arranged from coarse to fine.
2. The second stage is
biologic.
With the help of the so-called bio-balls (depending on model) the
settling of bio-organisms is stimulated. These bio-organisms remove the organic components
from the pond water (depending on model).
3. The third stage comprises a
UVC water treatment.
The UV light destroys swimming algae and
germs. The result is healthy water.
Commissioning
•
The pressure filter should be placed at least at a 2-meter distance from the pond edge. The
water outlet back to pond should be placed max. 2 m over the filter cover (0,2 bar water pres-
sure!).
•
The pump must be started first. The UVC lamp must not be operated as long as no water flows
through it. Do not use the UVC lamp if the lamp or the connections show damage signs. Do not
use the UVC-filter if there are people inside the water.
•
The built-in UV filter temperature sensor stops the UVC lamp. After cooling down, it is automat-
ically re-started.
•
The WilTec filter is delivered with all the necessary filter mats. Carefully wash the filter mats with
pond water before using. The bio-balls (depending on model) are placed at the bottom of the
filter, above put the grating with the protective tube for the UVC unit. Then put the filter foam
layers on it, arranged from fine to coarse. Put the cover lid on the housing and close the filter
with the supplied cramping bracket.
•
If properly installed, the filter is waterproof up to a 0,5 bar working pressure. The power supply
has to be equipped with an earth leakage circuit breaker that does not exceed 30 mA.
