Steam Connection Dn 20 (3/4" Bsp); Condensate Connection Dn 10 (3/8" Bsp) - Electrolux Professional IC6 48 FFS Series Installation Manual

3.6.1

Steam connection DN 20 (3/4" BSP) :

The customer must install a line purge, a manually closing valve with handwheel lockable in off position (do not use a
1/4 turn valve) and a filter on the supply side of the ironer.
The customer must install a safety valve if the boiler used operates at a pressure over the acceptable vapour of 1000
kPa maxi (10 bar).
The connection of a safety valve is compulsory in order to conform to the pressurised equipment directive
(DESP)
The valve must be CE certified in category IV.
Its size must vary according to the characteristics of the boiler, to the volume of the pipes upstream of the valve
and the volume of the appliance to be protected.
The drainage connector of the safety valve must absolutely be connected to the outside of the building and out of
reach human interference (on the roof for example).
3.6.2

Condensate connection DN 10 (3/8" BSP) :

The customer must install a steam trap with float closed and incondensibles drainage device (example : SARCO ref.
FT10C — G3/4" PN 25 or GESTRA ref. UNA15 h — G3/4" PN 25), a by-pass, a non-return valve and a manual clos-
ing valve lockable in off position.
After around 10 meters, the pressure loss in the condensate return pipes is too great.
It is therefore necessary to calculate its diameter according to the length of the pipes from the bleeders up to the
receiver tank, compared to the admissible pressure = 300 kPa maxi (3 bar).
