Quick overview

  • Tee included The switch ships with the tee it threads into, so the plumbing fitting is not a separate purchase.

  • Wide flow window Rated from 0.7 gpm up to 590 gpm, which covers small feature loops and full circulation lines.
  • Rated to 250 psi The pressure rating leaves plenty of headroom over normal pool system pressure.

  • Low voltage and line voltage Contacts are rated 300 VAC and 350 VDC at 0.5 A, 50 W.

Product details

The Harwil Q-12DS-C2/SUN860 is a flow switch supplied together with the tee it mounts into. It proves that water is actually moving in the line before the equipment it protects is allowed to run.

Ratings

The contacts are single pole normally open and rated 300 VAC and 350 VDC at 0.5 A, 50 W. The body is rated to 250 psi and the switch responds across a flow range of 0.7 to 590 gpm, so it suits both small loops and full size circulation plumbing.

Fitting

The connection is 1/2 inch MPT into the included tee. Because the tee is part of the package, a replacement swap needs no extra plumbing fitting, only the pipe work to bring the tee into the line.

Questions and answers

What people ask about this product, answered by our pool techs.

Does the tee come with the switch?
Yes. This listing is the Q-12DS-C2/SUN860 flow switch supplied with its tee.
What does SPNO mean here?
Single pole normally open. The contacts sit open with no flow and close once water moves through the tee, so the switch proves flow before equipment is allowed to run.
What flow does it respond to?
The switch is rated for a range of 0.7 to 590 gpm.
What thread size do I need in the plumbing?
The switch uses a 1/2 inch MPT connection into the supplied tee.
