AR22620 | TSS Unloader Assembly for AR630/AR767, 2600 PSI

AR22620 | TSS Unloader Assembly for AR630/AR767, 2600 PSI

• AR22620 TSS – AR70064 Unloader Assembly is an OEM-quality replacement unloader and Total Stop System (TSS) module for AR Blue Clean professional electric pressure washers.
• Rated to 2,600 PSI and engineered to restore factory bypass protection, motor shutoff, and consistent pressure regulation in one compact assembly.
• Direct-fit solution for AR Blue Clean AR630 and AR767 platforms where plumbing, mounting, and wiring must match the original build.
• Designed to reduce idle run time by stopping the motor during trigger-off conditions, protecting the pump, hoses, and fittings from heat and stress.
• Built for service environments where reliability, repeatable performance, and fast turnaround are priorities.

SKU Update: AR22620 Replaced by AR70064

• The AR22620 has been superseded by the updated SKU AR70064 as a design retrofit and upgrade of the same TSS unloader assembly.
• AR70064 carries forward the AR22620 form, fit, and function for AR630 and AR767 platforms, so existing repair and ordering workflows remain consistent.
• Orders placed for AR22620 are fulfilled with the upgraded AR70064 assembly, which reflects current production tooling and component revisions.
• No changes to plumbing, mounting, or electrical integration are required; the AR70064 retrofit installs in the same factory configuration as the original AR22620.
• Reference both AR22620 and AR70064 when sourcing parts to ensure correct identification during the transition.

System Function

• Combines unloader bypass regulation with an integrated TSS control that shuts the motor off during idle.
• Supports stable pressure delivery at the gun while reducing heat load created by extended bypass operation.
• Designed to protect the pump and plumbing by controlling pressure during trigger cycling and unattended idle.
• Helps reduce energy consumption and overall noise by eliminating unnecessary continuous motor operation.
• Engineered as a single replacement assembly to restore factory safety and operating behavior.

Operating Modes

• Trigger pulled: maintains regulated outlet pressure for consistent cleaning performance.
• Trigger released: diverts flow into bypass to prevent overpressure and stabilize the system.
• Total Stop System: detects idle condition and signals the motor to shut down, reducing wear and heat.
• Restart: trigger demand allows the motor to start and return to operating pressure without delay.
• Protection focus: reduces extended bypass exposure that can shorten seal and hose life.

Compatibility & Fit

• Direct OEM replacement for AR Blue Clean AR630 and AR767 models.
• Designed to match factory plumbing connections, mounting interfaces, and electrical integration points.
• Supports repair workflows where the goal is to restore original start/stop behavior and bypass control.
• Best choice when retrofitting is not acceptable and the equipment must remain in factory configuration.
• Intended for professional electric pressure washers that see frequent trigger cycling and idle periods.

AR22620 Included Components

• AR22620 unloader valve assembly with integrated Total Stop System (TSS) control, now supplied as the upgraded AR70064.
• Factory-assembled module intended as a single, replaceable unit.
• Designed to integrate with existing AR630/AR767 hose, gun, and accessory configurations.
• Packaged for service and repair environments requiring consistent parts identification and fit.

Materials & Quality Control

• OEM-precision fit engineered to AR factory specifications for direct, bolt-on replacement.
• Reinforced body designed to resist fatigue under repeated pressure cycling in professional use.
• Heavy-duty seals and O-rings selected for stable performance under frequent start/stop operation.
• Corrosion-resistant design intended for indoor or outdoor use with common detergents and wash environments.
• Factory pressure and function verification supports safe operation and consistent TSS behavior.

Serviceability

• Drop-in replacement approach supports fast restoration of performance in repair shops and fleet maintenance bays.
• Familiar connection points and adjustment access support straightforward commissioning after install.
• Routine inspection of seals, fittings, and electrical connections helps maintain reliable TSS performance.
• Designed to minimize teardown time and reduce repeat service calls caused by bypass heat damage.
• Supports preventative maintenance workflows where uptime and predictable operation matter.

Operating Guidance

• Confirm the washer model is AR Blue Clean AR630 or AR767 before ordering and installation.
• Depressurize the system fully, isolate power, and verify zero pressure prior to service work.
• After installing AR22620 (now shipped as AR70064), verify leak-free plumbing and stable pressure regulation under trigger cycling.
• Confirm TSS behavior by checking that the motor stops during trigger-off idle and restarts on demand.
• Do not allow extended idle bypass operation; TSS is designed to reduce that duty and protect the pump.

Applications

• Contractor-grade AR630 and AR767 pressure washers used on construction sites, fleets, and building maintenance work.
• Professional cleaning services that require reliable trigger cycling and reduced idle run time.
• Commercial and light industrial facilities where start/stop duty is frequent and equipment protection is critical.
• Rental fleets needing built-in safeguards to protect equipment across varied operators.
• Service shops rebuilding AR Blue Clean systems to restore factory safety, efficiency, and uptime.
