Installation requirements
Installation standard
All installation procedures should answer to the pertinent provisions of the national and local authorities.
Air-gap requirement
It is better to install the filter near the floor drain, the drain of the washer, and the vertical drain pipe, as
the wastewater must be able to flow off correctly from the washer. The drain pipe must be fixed, as the
water flows out of the drain pipe with high speed when flushing. Moreover, there must be an air gap of
approx. 4
cm between the end of the drain pipe and the bottom sieve. This gap can prevent that
wastewater be sucked back into the filter. The drain pipe cannot be inserted into the bottom sieve.
Installation requirement for drain pipe
The drain pipe should not exceed 3
m of length and be short and straight; otherwise, it could impair the
automatic flushing performance. It in particular water softening system that can have a flow rate going
from 19 to 38
ℓ
⁄
min
(5–10
gpm; the actual speed depends on the water source pressure). The depositions
are removed when flushing at a low water pressure.
