The VIQUA FRSS-1.5 flow restrictor is for use with VIQUA Point-of-Use UV systems. The flow restrictor is important because it slows the incoming water flow rate allowing the UV lamp to effectively treat all water that passes through the chamber.
It limits flow to 1.5 GPM so compatible point-of-use UV equipment receives water at the intended treatment rate.
Q:
Which systems does the catalog list?
A:
The catalog lists these compatible parts or systems: FRSS-1, S1Q-PA, SC1. Confirm the exact model number on your equipment before ordering VIQUA FRSS-1.5.
Q:
What connections does it use?
A:
It has 1/2-inch female NPT connections on both ends. Match thread type and plumbing size.
Q:
Where should it be installed?
A:
Install it in the location and flow direction specified by the UV system manual; do not place it where it creates an unsafe pressure condition.
Q:
Can I substitute a higher-flow restrictor?
A:
No. A higher flow rate can exceed the system design. Match the 1.5 GPM rating to the supported equipment.
Q:
What can cause low flow besides the restrictor?
A:
Loaded prefilters, closed valves, low supply pressure, tubing restrictions, and scale can also reduce flow. Diagnose the complete water path.
