Connecting the steam
The steam supply must be cut off and must not be under pressure.
Steam inlet
• The branch pipes must be located at the top of the main steam pipe to prevent condensation in the steam.
• The branch pipe must have a descending gradient and must end at a height above the inlet connecting branch (5).
• Mount a plug valve (A) and a strainer (B) in the branch pipe.
• If the branch pipes are too far away from the main pipe, to maintain quality of the steam, it is recommended to in-
stall a steam trap (F).

Condensate return
It is important that the branch pipe for condensed water on return to the main condensate pipe has a descending gra-
dient and is lower than the outlet connecting branch (6).
• Mount a strainer (D) in the return pipe.
• Mount a mechanical water discharger (C) after the dirt collector (D).
• Mount a plug valve (E).
• Mount pressure hoses between the branch pipes and the machine. Note that hoses are not supplied.
