PRESENTATION:
WDF 20000 is a complete, compact filtering system developed specifically to clean garden ponds.
Its small size facilitates maintenance work and means it is easier to find space for it in the garden.
Working together with the TX 3800 pump, suitable for continuous duty, it purifies water in four successive stages:
- UV-C sterilizing filter, which eliminates bacteria and helps eliminate algae.
- mechanical filtering consisting of a decanting stage and subsequent filtration through sponges.
- aeration stage through wet & dry screen, which replenishes the water's oxygen levels and encourages gaseous exchange
with the atmosphere.
- biological filtering, whereby the filter develops effectively on the surface to promote the growth of beneficial bacteria
colonies.
This is how the system keeps the water in your pond clear and clean.
SAFETY RULES:
- make sure the voltage on the product's label matches mains voltage.
- The product must be plugged into an earthed socket.
- It is essential the product be protected upstream by a residual current circuit breaker (mains trip switch) with a tripping
current < 30 mA.
- Before connecting the unit to the mains, make sure the cables are not damaged in any way.
- The product features a Z connector, namely the cables and plugs cannot be replaced or repaired. If either is damaged,
the whole unit must be replaced.
- WARNING disconnect the unit from the mains before carrying out any kind of maintenance in or out of the water. If
the plugs or power socket are wet, switch off
power with the master switch before unplugging the power cords.
- to stop accidental dripping from wetting the plug or power socket, use the cable to create a drip loop below the level of
the plug.
- when installing and maintaining the unit, do not lift it by the power cord.
- keep out of reach of children.
- do not operate the product with corrosive or abrasive liquids.
- protect from freezing conditions. Do not use the unit and instead remove it from the water if there is any danger of the
water freezing.
- The product cannot be used in water hotter than 35°C.
- The WDF 20000 filter has been designed for use outdoors, but must never be immersed in water.
- DANGER: avoid direct contact with UV-C light, which can be dangerous for eyes and skin.
- To prevent the lamp overheating, switch it off when no water is running directly past.
- WARNING: Stop using the UV sterilizer temporarily during treatment with water and/or fish care products.
- WARNING: the lamp must be changed by qualified personnel only.
ASSEMBLY AND INSTALLATION:
- install the UV-C sterilizer in the compartment under the case, fastening it with the relevant fittings and rubber seal as
illustrated on page 1 (A, B)
- install the drain valve with the relevant fittings and seal as illustrated on page 1 (C)
- install the outlet fitting with the relevant filter and seal as illustrated on page 1 (C)
- position the sponges as illustrated on page 2 (D)
- place the biological filtering material in the relevant compartment as illustrated on page 2 (D)
- position the wet & dry perforated screen as illustrated on page 2 (D)
- assemble the cover with the 8 pipes and sponge retaining grid. (E)
- INLET connection: connect the pump with the hose-end fitting and 3m helically wound hose to the UV-C sterilizer's
inlet as illustrated on page 2 (F) Where necessary, use a clamp to make the connection more secure.
- OUTLET connection: connect the 1m helically wound hose to the outlet fitting as illustrated on page 2 (F) Where neces-
sary, use a clamp to make the connection more secure.
- determine which point near the pond makes the best location, bearing in mind the lengths of the pipes supplied.
- Switch on the pump, check to see that the filter fills and that water comes out of the outlet correctly. It is not a problem
