Important - Suction Line Routing and P-Trap Formation
Best Practices That Must Be Followed (Refer to the illustration on following page)
1. All hose bends must maintain at least minimum bend radii with no kinks. See “Minimum Bend Radii” on page 35.
2. Suction line should have a slight (if possible) downhill angle from the unit towards the compressor. Horizontal angle is acceptable - uphill angle is not.
3. Hoses should be secured adequately to prevent rubbing or chafing against hot, sharp or moving components.
4. P-Trap to be formed immediately before vertical run upwards to compressor while maintaining minimum bend radius with no kinks. It should be a
minimum of 2” below the lowest point of the horizontal run hose as shown.
5. After vertical run, the suction line must be horizontal or downwards to the compressor and cannot have any sag or droop.
