Correct Electrical Installation; Safe Operation; Common Features - Oase ProfiClear Classic Instrucciones De Uso

Correct electrical installation

• Electrical installations must meet the national regulations and may only be carried out by a qualified electrician.
• A person is regarded as a qualified electrician, if, due to his/her vocational education, knowledge and experience, he
or she is capable of and authorised to judge and carry out the work commissioned to him/her. This also includes the
recognition of possible hazards and the adherence to the pertinent regional and national standards, rules and regu-
lations.
• For your own safety, please consult a qualified electrician.
• The unit may only be connected when the electrical data of the unit and the power supply coincide. The unit data is
to be found on the unit type plate or on the packaging, or in this manual.
• Minimum safety distance between the unit and the water: 2 m.
• In this case, use filter module M 1 (pump chamber) to safely install the filter pump in conformity with the standards.

Safe operation

• Only use original spare parts and accessories for the unit.
• Never carry out technical modifications to the unit.
• Only have repairs carried out by customer service points authorised by OASE.
• Ensure that the filter will not overflow. Danger of emptying the pond.
Function of the ProfiClear Classic module filter
The ProfiClear Classic module filter is a modular open filter system for the mechanical and biological cleaning of pond
water. It consists of 4 filter modules (M 1 - M 4) which can be combined in any desired way or can complement existing
configurations to meet the most varied requirements.
Module M1 (pump chamber)
Module M1 (pump chamber) is used to reduce pressure loss and excessive sludge formation in the filter pump as well
as for the safe installation in swimming ponds in conformity with the standards. Depending on the operating mode,
module M1 is installed downstream of other filter modules (principle of gravity) or upstream (pumped system).
Module M 2 (Screenex coarse soiling separator)
With its two large surface Screenex separating sceens, Module M 2 (Screenex coarse soiling separator) permits the
mechanical removal of solid matter up to a particle size of 800 microns from the pond water.
Module M 3 (foam filter)
Module M 3 (foam filter) ensures the mechanical and biological cleaning of pond water. The pores of the foam inserts
for a large internal surface for micro-organisms to adhere to. The foam inserts are of different densities. In this manner
zones are created causing the water to flow at different speeds. The adherence of those micro-organisms is favoured
in zones of high flow speed (reduced filter density), which ensure the conversion of ammonia into nitrate (nitrification)
via nitrite. An external connection at the filter module improves the higher oxygen intake required for this purpose. The
adherence of anaerobic micro-organisms is supported in zones of low flow speed (higher filter density), which assist a
reduction of the nitrate / nitrogen ratio (denitrification) which can then leave the pond as gas.
Module M 4 (posphate binder)
The purpose of Module M 4 (phosphate binder) is to convert nitrate into gaseous nitrogen (denitrification) and, above
all, to bind phosphates which, in particular, notably restricts the growth of string algae. The majority of the volume is
filtered in the secondary flow. In this manner, a low oxygen environment is created inside the foam filters which favours
the adherence of denitrificating micro-organisms. The smaller part of the volume flow is guided through the Phosless
inserts where special phosphate binders ensure the adherence of the phosphate.

Common features

Modules M 2 - M 4 are fitted with variable connections, a water level display to check the degree of soiling of the filter
inserts (maintenance requirement with pumped systems; no function with the principle of gravity), a thermometer to
check the temperature, an air connection to enrich the water with oxygen when running into the filter module, as well
as a spray system to clean the filter module. All modules have a dirt drain with stop valve for the controlled drain of dirt
water during the cleaning process.
The maximum throughflow of a filter module is 12,500 litres per hour; the optimum throughflow (optimum effective
range) is 6,000-8,000 litres per hour (DN 100). For larger ponds and/or load, we recommend to install additional mod-
ules in parallel to double the throughflow.
