Special installation
Installation with suction diffuser and triple-duty valve
Do not install and operate triple-duty valves and suction diffusers in closed systems unless
the system is designed with these safety and control devices:
• Pressure relief valves
• Compression tanks
• Pressure controlling equipment
• Temperature controlling equipment
• Flow controlling equipment
Check that the control and safety devices have these characteristics:
• Properly sized for their purpose
• Placed correctly in the system before putting the system into operation
Installation with isolation base
When using an isolation base, flexible piping should be used on both suction and
discharge sides to reduce the strain on the flanges.
