Salt Off Connection Kit Installation

For Flushmaster Controller owners · One kit per active outlet hose

Use this guide to add the Salt Off dispenser to an individual Controller outlet hose. Controller and outlet hose are sold separately.

Before you cut: Install after the Controller, in the hose leading to one engine. Each active outlet needs its own kit. A shared dispenser before the Controller can use its solution during the first engine’s cycle.

Controller outlet → outlet hose → dispenser → remaining outlet hose → engine flush connection

Connection guide: threaded hose barb at the Controller-side shutoff valve; choose straight or 90-degree fitting toward the engine; one clamp on each hose connection
The shutoff-valve end faces the Controller. Choose the straight or 90° fitting for the engine side.

Check your parts

  • 32 fl oz STAR BRITE Salt Off Concentrate
  • 4 fl oz STAR BRITE solution dispenser
  • Two 316 stainless steel hose clamps
  • 1/2-inch threaded hose barb
  • 1/2-inch straight female hose barb
  • 1/2-inch 90° elbow hose fitting

Use the straight or 90° engine-side fitting. Keep the unused fitting as an alternative. Have a suitable hose cutter and a driver for the clamps ready.

Install your kit

Before you start: Stop the Controller, turn off the water supply and release pressure. Choose an accessible position with room to reach the dispenser controls and refill the cup. Follow the dispenser's labeled flow direction and the flushing instructions for your engine.

  1. Choose your engine-side fitting. Use the straight female barb for a straight hose route, or the 90° elbow where the hose needs to turn. Set the unused fitting aside.
  2. Assemble the dispenser connections. Thread the Controller-side barb into the dispenser's shutoff-valve end. Attach your chosen straight or 90° fitting to the opposite end. Align the fittings before securing them in the hose so the fixed threads do not twist the hose.
  3. Cut the outlet hose. Make a clean cut at the chosen position. This is the hose running from a Controller outlet toward the engine, not the main freshwater supply hose.
  4. Connect the Controller side. Slide one clamp onto the cut hose end closest to the Controller. Push that hose fully onto the Controller-side barb, then position and tighten the clamp over the barbed section.
  5. Connect the engine side. Slide the second clamp onto the remaining cut hose end. Push the hose fully onto the chosen straight or 90° barb and tighten the clamp. Keep the hose free of kinks and the dispenser supported.
  6. Test with water only. Use the dispenser's water-only setting and open its flow control according to its instructions. Restore water and run a test of that outlet using your engine's approved flushing procedure. Check both threaded connections and both hose clamps for leaks and confirm water reaches the engine. Stop and correct any leak or restricted flow.
  7. Fill and flush. Stop the Controller, turn off the supply and release pressure before opening the dispenser cup. Add Salt Off as directed on its label, securely reinstall the cup and select the labeled treatment setting. Restore water and start the Controller. Follow your engine manufacturer's required procedure and flush duration.

Never run an engine through a flush-port connection unless its manufacturer expressly permits it. Follow the Salt Off and dispenser instructions for solution quantity, settings, rinsing and storage. Do not leave concentrate in the dispenser between uses.
