Note: These are guidelines only. Exact pipe sizing to be carried out for each application.
"H" models include HV and GP range
"M" models include C, F and M range
"L" models
The exact pipe size should be determined by application.
Recommended maximum vertical change 5 metres. The suction lines have been selected to achieve a pressure drop of 2psi or less whilst maintaining refrigerant velocity in the horizontal
plane of 3.5m/s (700ft/min) and in the vertical plane of 7.0m/s (1500ft/min) to achieve oil return.
