AR23299 | TSS IDR Unloader Assembly

AR23299 – TSS IDR Unloader Assembly

• Premium, factory-style unloader assembly combining pressure regulation, instant bypass, and TSS readiness.
• Protects pumps from overpressure and heat buildup during idle conditions.
• Supports automatic motor/engine shutdown when paired with a TSS switch or pressure-sensing circuit.
• Integrated design reduces loose fittings, leak paths, and installation complexity.
• Ideal for contractors, rental fleets, industrial facilities, and maintenance shops.

What “TSS IDR” Does for Your Rig

• Stable pressure regulation with balanced piston/seat assembly to eliminate hunting and chatter.
• Instant, smooth IDR bypass for cooler operation and extended seal life.
• Full TSS (Total Stop System) compatibility for auto stop/auto restart functionality.
• Reduces energy use, noise, fuel consumption, and pump dead-head risk.
• Simplifies system plumbing by integrating regulation and TSS interface in one unit.
• Does not include detergent injector; use a downstream injector for soap applications.

Compatibility & Use Cases

• Designed for commercial triplex pumps used in contractor and industrial systems.
• Match GPM, pressure, and porting when pairing with AR pumps.
• Suitable for M2 (Mini-Matic), C2 (Gymatic), and VR/VR35 system families.
• Applications include fleet washing, contractor trailers, rental units, indoor wash bays, and multi-gun systems.

AR23299 Installation

• Follow flow arrows and use detergent-safe thread sealant during plumbing.
• Route bypass to a supply tank for best thermal management; add thermal relief if returning to inlet.
• Wire TSS switch into motor contactor or engine kill circuit per OEM schematic.
• Install a liquid-filled pressure gauge and purge air before setting pressure.
• Adjust pressure with gun open; lock setting after verifying smooth bypass transitions.
• Test TSS: confirm shutdown on trigger release and instant restart when reopened.

Safety Tips

• Use components rated for full system pressure.
• Avoid dead-heading and limit extended bypass operation.
• Depressurize system before servicing.
• Verify chemical compatibility across all fittings and seals.

Maintenance & Troubleshooting

• Perform weekly checks for leaks, pressure drift, or slow bypass response.
• Keep inlet filters clean to prevent accelerated seat and piston wear.
• Address heat issues by enlarging bypass return, reducing idle time, or routing to tank.
• Rebuild when symptoms include pressure spikes, creep, hunting, or inability to reach set pressure.
• Electrical issues: verify TSS switch alignment, pressure settings, and contactor/kill circuit function.
