The lost water resulting from the bubble trap is not suitable for feedback into the
process.
For the hose system, use PVC hoses with an internal diameter of 12 mm (3/8").
Secure the hose system with worm drive hose clips (not included in the delivery).
The inlet and outlet connection of the flow assembly are always identical, the system is
symmetrical.
Install the flow assembly vertically.
The supply must be connected at the bottom (upward flow in the pipe).
Insert a orifice plate into the upper process connection (

assembly to get the desired volume flow rate (included in the delivery):
• 1 mm for volume flow rate < 60 l/h (15.8 gal/hr)
• 3 mm for volume flow rate 60 to 100 l/h (15.8 to 26.4 gal/hr)
• 5 mm for volume flow rate > 100 l/h (26.4 gal/hr)
Avoid buckles and loops in the hose system.
