a) ElectricalAll single-phase types : 230 V - 50 Hz

115 V - 60 Hz

Tension standard : — tolerance 50 Hz ± 10 %,— tolerance 60 Hz ± 6 %,

b) Assembly— Assembled directly on horizontal or verti-

cal pipe on the distribution ring returnafter the purge stations.

— Motor axis always horizontal.

Coupling to the installation :According to the installation :— copper welding fittings (R) or brass screw

fittings (brass RU ) on copper pipe,— steel screew fittings (RU) on galvanised

steel pipe.

c) Packaging— Supplied with gaskets, without unions.

d) Maintenance– Unit replacement.
