– Maintain the prescribed tightening torques
(→ 9.2.5 Tightening torques, Page 37).
5.3.3 Installing auxiliary pipes (if available)
Follow the manufacturers' specifications for any available
auxiliary systems.
1. Connect the auxiliary pipes to the auxiliary connections s o
that they are stress-free and do not leak (→ setup drawing).
2. To a void air pockets, run the pipes with a continuous slope
up to the pump.
