VIQUA FRSS-8.9 Flow Restrictor 8.9 GPM 3/4" FNPT
VIQUA FRSS-8.9 Flow Restrictor 8.9 GPM 3/4" FNPT
Description
The VIQUA FRSS-8.9 flow restrictor is for use with VIQUA Point-of-Entry 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.
- Flow Rate: 8.9 Gallons Per Minute
- 3/4" x 3/4" FPT
- Material: 304L stainless steel
Q:
What does the VIQUA FRSS-8.9 do?
A:
It limits flow to approximately 8.9 GPM under specified conditions, helping maintain the exposure time used in the compatible UV-system design.
Q:
Which systems use the VIQUA FRSS-8.9?
A:
The catalog lists: FRSS-8, PUV-7-P, UVMax C4, D4 (650694-R), D4 Premium (660089-R), D4+ (650695-R), IHS22-D4, VH150, VH200, VH200-F10, VH200-V. Confirm the exact model and part number on your equipment before ordering VIQUA FRSS-8.9.
Q:
What connection size does it use?
A:
It uses 3/4-inch female NPT connections. Confirm thread size, flow direction, and available installation length.
Q:
Will actual flow always equal the labeled rate?
A:
Actual flow can vary with pressure, temperature, plumbing resistance, and installation conditions. Verify system performance after installation.
Q:
Can I use a different restrictor size?
A:
Do not substitute a different flow rating unless the equipment manufacturer approves it; excess flow can move water through the chamber faster than intended.
Q:
Where should it be installed?
A:
Install it in the location and direction shown in the system manual, with appropriate support and access for service.
