The SiClean efficiently removes sludge from heating systems by
means of natural physical phenomena.
Water from the system enters the separator through the lower pipe.
The constant thrust of the circulation pump drives the water slowly
first down, then up in the separator. Particles in suspension fall by
their own weight into the bottom of the settling chamber. Under the
action of polar magnetic field, the ferromagnetic particles accumulate
on the inside wall of the separator.
The separator has a "pressure relieving" effect in the fluid flow, and
promotes ventilation through the automatic air vent.
Stopping the circulation pump, opening and closing the valves and
removing the magnet bars (to eliminate the magnetic field). When the
system is drained, the internal housing of the separator is cleaned
automatically by a countercurrent flow.
DANGER! Risk of fatal injury!
Incorrect installation and improper electrical connections can
result in fatal injury.
• Have the electrical connections established by approved electri-
cians only, in compliance with the applicable regulations.
• Observe the accident prevention regulations!
CAUTION! Risk of material damage!
Danger of damage due to incorrect handling.
• Have the product installed by qualified personnel only.
NOTE
So as not to perturb the operation of the heating or air-conditioning
network, it is essential to maintain a constant pressure in the network.
Provide an automatic water supply because of the loss of water due to
sludge disposal.
To maintain pressure and ensure water feed you can install a pres-
sure-maintaining system Wilo-WEH/WEV.
• Install the SiClean in a room which is easily accessible, well ventilated,
frost-proof and protected against rain.
• Ensure that the dimension of the technical room door is adequate to
enter the system.
• Adequate space must be provided for maintenance work. The instal-
lation should be freely accessible from at least two sides.
• The installation surface must be even and horizontal.
