Cleaning the filter sponge with crank (CPF-2500-5000-10000-15000-20000-30000)
The filter sponge can be cleaned by turning around the cleaning handle. Installation guidelines
with regard to the clear water guarantee, the following installation guidelines must be ob-
served.
Please read the following notes in order to ensure that the water always is cleaned sufficiently:
◦
The filter system has to remain switched on for 24 hours a day.
◦
The UV lamp should be changed after 8000 operating hours so that the device can work
effectively and efficiently. The filter system must be cleaned regularly.
Connecting the pump
On the filter cover/lid, there are three connections equipped with hose tails:
◦
The pump is connected to the first hose tail. Use a hose diameter that is the same with the
diameter of the pump outlet. Saw off the diameter-hose steps that you do not need.
◦
The hose tail in the middle of the filter cover/lid is the outflow to the pump. Connect to the
large diameter of the tail a suitable hose and cut away the rest of the tail diameter. To
avoid the loosening of the hoses please use hose clamps.
Never use the filter with a built-in UVC unit with a water pressure higher than 0,2 bar! The
height difference between the filter lid and the pressure-free outflow point of the supply line
can amount to max. 2 m. The pressure of the water pumped to the filter cannot exceed
0,5 bar. Use the filter only with hoses that can withstand at least a pressure of 0,2 bar, the
max. pressure of the pump.
Make sure that outflow /discharge in the pond is positioned on a clean place. If the outflow is
blocked a higher pressure may result. Higher pressure can lead to leaking spots in the filter
and therefore to a complete emptying of the pump.
When the filter is used in “filter-modes,” the user should be careful and make sure that all
seals are properly installed in order to avoid the emptying of the pond. The sealing cap func -
tions simultaneously as safety measure in “Clean” mode. Make sure that filter always operates
in the “Filter” mode as long as the pump is running. The filter should be set on “Clean,” if the
filter sponges are cleaned. Before you start the filter, check and make sure that all hoses and
seals are correctly fastened. Filter only water and no other fluids. By frost the filter has to be
removed. Do not expose the filter to the direct sun light.
After the filter has been placed on the right place and the pump has been connected the integ -
rated UV-unit can be switched on.
UV unit
The WilTec filter is delivered with all the equipment you need, and an integrated UV unit. The
UV lamps have approx. 8000 working hours that correspond to a season period of use from
March till November. The UV lamps can be replaced by loosening the screws from the spher -
ical upper part of the cover lid.
It is recommended to change the UV lamp with a new one at the beginning of the season.
The UV lamp clears as the green water and destroys germs. The WilTec filters have a separ-
ate chamber, through which UVC rays are not exposed to contact with the filter media. Be-
cause of this the micro organisms in the filter material are not damaged.
