In order to prevent overflowing from the condensate
collection tank and resulting flooding of the machine and
the room in which it is installed, the siphon must be fitted
with a DRAIN VALVE to permit the removal of impurities
that settle on the bottom (fig. 23).
In order not to undermine the operation of the drainage
system, pressurised siphons and siphons operating under
suction pressure must not be connected together.
THE WASTE PIPE (fig. 24) leading to the drainage
network:
- Must not be connected directly to the siphon in order to
absorb air or waste backflow and to permit direct visual
control of the correct outflow of waste water
- Must have a diameter larger than the drain pipe and a
minimum angle of 2% to ensure proper functioning.

FILTRATION SECTIONS

Check the correct installation of the prefilters located in
the relevant counter-frames with safety springs or guides.
The electrical connection and installation instructions for
the rotary filtration section are provided in the specific
manual provided. The instructions for introduction of the
reconditionable filtration diaphragm are set out in the
maintenance chapter (6.2.3.).
After removing the filters from the packing (in which they
are supplied to prevent deterioration during transport
and on site), place the bag, absolute and active carbon
filters in the relevant section, taking care to ensure rigid
assembly and perfect gasket tightness.
This operation must be performed about one hour after
the unit has been started up for the first time, when dust
and installation residue have been removed from the
ducts. In this way the non-reconditionable filtration
sections will be preserved.
On request, TCF supplies differential analogue pressure
gauges (fig. 25) or oil-column, gauges (fig. 26) of the types
shown.
