1. Why Genuine UltraMax II Mark V Series A Control Box Parts Matter

Exact Engineering Meets On‑Site Reality

Graco’s control boxes (a.k.a. “SmartControl” for Series A) combine pressure sensing, electronics, and rugged packaging. OEM parts ensure your system retains its accuracy and durability—no misreads, no shorts, no system instability.

Withstands Harsh Conditions

Spray sites vary in temperature, dust, and moisture. Genuine parts are tested under these conditions with rated IP protection—not knock-offs. That means better moisture ingress protection and proven chemical resistance.

Warranty & Expert Support

Only OEM control parts keep both Graco’s warranty intact and earn you access to our technical team trained specifically on UltraMax II electronics. We help identify firmware versions, part numbers, and wiring harness builds.

2. Control Box Parts Overview – Key Components

The UltraMax II Mark V Series A system breaks down into several designated parts:

1. SmartControl Module
   The “brain” of the system. Handles pressure regulation, diagnostics, and user interface.

2. Pressure Transducer
   Detects fluid pressure from the gun and signals the module to stop/start.

3. Power Switch Assembly
   The heavy-duty on/off rocker switch rated for field conditions.

4. Wire Harness & Connectors
   Rugged, quick-disconnect connectors that channel signals and power.

5. Indicator LEDs & Buttons
   Provide spray status, warnings, and reset or bleed-off control.

6. Enclosure & Mounting Hardware
   Compact, powder-coated metal housing and bracket with vibration dampening.

7. Software or Firmware Chips (sometimes critical for newer firmware patches).

Having each part available OEM means repairing instead of replacing the entire unit—big cost savings.

3. Key Features & Specs to Watch

Each part listing on Sprayersandparts.com includes essential specifications:

• Material Grades: rugged thermoplastics, stainless fasteners, IP67 sealing where applicable.

• Voltage Ratings: 115/230 VAC range, overload protections included in OEM parts.

• Fluid-Pressure Ratings: all rated for 3,300 PSI maximum.

• Connectors: keyed to specific Graco harness formats—no cross-compatibility errors.

• Part Diagrams: linked to exploded diagrams for accurate identification and ordering.

These specs matter because even small mismatch errors—like wrong pin-count harness connectors—can disable the whole sprayer.

4. Model Compatibility & Build Variants

The UltraMax II Mark V Series A underwent minor hardware refreshes but retains common compatibility across:

• Mark V UltraMax II Series A (serial range Yxxxxx–Zxxxxx)

• Only some parts change (e.g., sub-model serial suffix) – our system helps you confirm correct fitment.

International or Canadian builds have identical control box parts. Our search system includes dozens of serial-compatible part matches.

5. Fast Shipping & Pro Technical Support

Your order, your way:

• Same-Day Shipping if by 12 PM Central (Mon–Fri) from Graco warehouse (Terms & Conditions apply)

6. Pro Tips for Long-Term Control Box Health

Minimize future issues with these strategies:

• Recover firmware mid-life—Solder-in modules last longer

• Clean connector pins and apply dielectric grease

• Install a GFCI or breaker on your power feed

• Torque the board screws to spec: 48 in-lb

• Keep harness away from heat or spray

11. Fitment Questions Contractors Ask

• My board flashes 3 green blinks, parts mismatch? It’s firmware vs. harness signatures—our serial-ranged listings include correct versions.

• I see two transducers—one monitors feed, one isn’t replacing? Only one is OEM recommended for Series A boards.

• What’s the torque spec for mounting screws? 48 inch-lbs torque, clockwise only.

• Can I retro-fit USB firmware flash port? Series A was never field upgradable—buy updated kit or full board.

We’ll advise you through every step.
