9.1.4 INSTALLATION WITH MIXED ROUTING
The pipe routing of the system to be developed may have characteristics similar to more than one of the examples de-
scribed above. In such systems, it is important that the following instructions be followed for each type of section:
Supply pipes
Vertical climbing sections (Uprights) (Height dierence 0 ÷ 15 m)
Ensure a gradient of 2% along the horizontal sections toward the condenser
Insert oil traps (siphons) at the start of each vertical climbing section
Insert oil traps (siphons) every 5 metres of vertical climbing section
Insert a back-siphon on the supply pipes at the end of the vertical section
Vertical descending sections (Uprights) (Height dierence -1 ÷ -10 m)
Ensure a gradient of 2% along the horizontal sections toward the condenser
Line insulation
Internal Required
External For aesthetic reasons only, or in the event of risk of contact with people
Liquid pipes
Install the check valve as close as possible to the air-cooled condenser
Internal Required
External Only if exposed to the sun, for aesthetic reasons only, or in the event of risk of contact with people
