Pipe insulation
Connection pipes must be thermally insulated to prevent dispersions of
heat or formation of condensate.
1 Gas pipe
2 Condensation discharge
3 Liquid pipe
4 Heat insulation
5 Adhesive tape
– insulate the liquid and gas pipes separately
– use insulating material that is thicker than 15 mm
– ensure that the insulating material adheres to the pipe without
gaps
– fix using adhesive tape
Do not tighten the adhesive tape too much, so as to avoid
damaging the insulation.
Avoid partial insulation of the pipes.
In case of use with outdoor temperature above 30 °C and relative
humidity above 80%, increase wall thickness up to 20 mm.
For gas pipes:
– ensure that the material used resists to temperatures up to
120°C
For liquid pipes:
– ensure that the material used resists to temperatures up to
70°C
2.12 Condensate discharge connection
is provided with a tray that collects condensate generated
during the cooling operation, which must be conveyed into a suitable
place for discharge. Sizes and position of the discharge pipe are
indicated below.

3 Insulating material
– connect a rubber drainage pipe
– direct it toward a suitable place for discharge
– insulate the joints
The discharge system must feature a suitable syphon in order to
prevent air from entering the vacuum system. The syphon also
prevents odours and insects from entering the system.
The syphon must feature a plug in its lower part or must otherwise
allow for a quick disassembly for cleaning purposes.
Ensure that all joints are properly sealed so as to prevent water
leaks.
The drainage pipe must be insulated for sections running inside
houses in order to prevent condensate formation on its surface.
