5.2.5 Telescope suitable for light traffic

To ensure the function in areas traversed by light traffic, the telescope must be embedded around the

collar with lean mixed concrete.

The concrete encasement must be uninterrupted, 20 cm wide and approximately 30 cm deep.

Attention: It is important to use the cast steel cover. Transport vehicle weight of heavy goods vehicles

and machinery is not permitted. The telescope must be sufficiently embedded and supported that no

forces are transferred to the housing.

6.1

Commissioning

Before putting the system into use the filter sieve

surface is to be thoroughly cleaned with asolvent based

cleaning fluid. Alternatively the filter sieve may be

cleaned in a dish washer (40° - max. 60°). Any dirt that

gets into the filter housing during the assembly must be

thoroughly removed.

The filter sieve functions only in one flow direction due

to the designed structure, the direction is marked on the

metal ring with an arrow on the inlet side. When

installing the filter cartridge pay attention that the joint

seam of the sieve surface is positioned upward.

6.2

Service

The complete system is to be inspected at least every 3

months for leakage, cleanliness stability. To ensure the

expected water yield is delivered, it is important to

inspect and to clean the filter sieve at regular intervals.

When carrying out a regular service of the integrated

filter it is also required that the overflow siphon is

checked and cleaned.
