Scotsman AP1-P AquaPatrol™ Plus Water Filtration System Single System 2.1 Gallons Per Minute Max Flow

Protect the water side of your Scotsman ice machine with one purpose-built system.

The Scotsman AP1-P AquaPatrol™ Plus combines dirt and rust reduction, phosphate-based scale inhibition, and chlorine retention in a complete single-cartridge package. Instead of relying on a generic filtration setup, qualifying operations get a compact system rated for flow up to 2.1 GPM and designed to support cleaner conditions inside compatible Scotsman equipment.

Scotsman rates this system for cubers producing up to 650 pounds of ice and flakers, nugget machines, and nugget dispensers producing up to 1,200 pounds. When the machine, incoming pressure, and water conditions meet the published requirements, it’s a straightforward way to put Scotsman’s intended treatment approach ahead of the equipment.

The Scotsman AP1-P isn’t a universal filter, water softener, or complete purification system. Confirm the full ice-machine model, required flow, water conditions, plumbing connections, and service space before ordering.

Confirm the complete water-treatment setup before purchase.

Understand why AquaPatrol Plus retains chlorine.

Many carbon filters remove chlorine to address taste and odor. AquaPatrol Plus takes a different approach: it leaves chlorine in the incoming water to help keep the ice machine cleaner. Scotsman states that its ice-making process then removes noticeable chlorine from the ice. The filtration media also reduce dirt and rust particles, while the phosphate feed helps inhibit mineral deposits.

That distinction matters when comparing Scotsman filtration families. SSM Plus uses a separate approach that includes half-micron filtration and chlorine, taste, and odor reduction. AquaPatrol Plus retains chlorine. The systems also use different replacements: AP1-P uses APRC1-P, while SSM Plus uses an SSMRC cartridge.

Don’t assume that either approach solves every water problem. High hardness, iron, chloramines, heavy sediment, or unusual taste and odor concerns may require water testing and additional treatment. Use the system only with microbiologically safe water or water that receives adequate disinfection before or after filtration.

Match the 2.1 GPM system to the exact ice machine.

The production ranges are an initial application guide, not automatic proof of compatibility. Confirm the complete machine model, peak fill rate, incoming pressure, and Scotsman’s current filtration recommendation. If the connected load needs more than 2.1 GPM, review a higher-flow AquaPatrol Plus configuration rather than exceeding this system’s rating.

Plan cartridge replacement from actual operating conditions.

Scotsman’s current system specification sheet doesn’t provide a fixed gallon capacity or universal replacement interval for the APRC1-P cartridge. Follow the system instructions, cartridge labeling, and site maintenance plan instead of borrowing another filter’s schedule.

Water use, sediment loading, pressure, and local conditions can all affect cartridge life. A loaded cartridge may cause reduced downstream flow, longer machine fill times, or unexpected production changes, but those symptoms don’t prove that the cartridge is the cause. A closed valve, kinked line, clogged inlet screen, low building pressure, or an ice-machine component can create similar problems.

Record the installation date and any available pressure or flow readings. The ice-machine water-filter replacement guide explains how time, water use, pressure loss, and site conditions can guide service planning.

Allow enough access for installation and routine service.

Place the assembly where the filter head, cartridge, fittings, and shutoff remain accessible without moving the ice machine. Leave working room to remove the cartridge, restore water, flush the system, and inspect for leaks.

Keep water and air within the published temperature ranges, and maintain pressure between 20 and 80 PSIG. Follow current Scotsman instructions and local plumbing requirements for mounting, connection, flushing, and commissioning. A compact filter only stays convenient when it can be serviced cleanly.

Keep filtration, scale removal, and sanitizing separate.

The phosphate feed helps inhibit mineral buildup; it doesn’t remove scale already inside the ice machine. Replacing the cartridge also doesn’t clean the water circuit or sanitize ice-contact surfaces. Continue the machine’s prescribed cleaning, descaling, and sanitizing program even when filtered water is used.

Our commercial ice-machine cleaning guide explains why cleaning, descaling, and sanitizing require separate procedures. Always use the exact machine manual and approved chemicals for the work.

Frequently asked questions about AquaPatrol Plus

What does the Scotsman AP1-P water-filtration system do?

The Scotsman AP1-P reduces dirt and rust particles, retains chlorine in the incoming water to help keep compatible equipment cleaner, and supplies phosphate to inhibit mineral buildup. It is a complete single-cartridge AquaPatrol Plus system rated for flow up to 2.1 GPM.

Which Scotsman ice machines can use this system?

Scotsman specifies it for cubers producing up to 650 pounds and flakers, nugget machines, and nugget dispensers producing up to 1,200 pounds. Confirm the exact model, water demand, pressure requirements, and current Scotsman recommendation before ordering.

Does the Scotsman AP1-P remove chlorine?

No. AquaPatrol Plus intentionally leaves chlorine in the incoming water to help keep the ice machine cleaner. Scotsman states that its ice-making process removes noticeable chlorine from the ice. Don’t apply the chlorine-removal claims of the separate SSM Plus system to this product.

How often should the AP1-P cartridge be replaced?

Scotsman doesn’t publish a universal gallon capacity or fixed replacement interval for the APRC1-P in its current system specification sheet. Follow the cartridge instructions and site maintenance plan, and investigate confirmed flow or pressure loss that may indicate an earlier change is needed.

Which replacement cartridge fits this system?

Use one APRC1-P replacement cartridge. APRC6-P is the same AquaPatrol Plus replacement supplied as a six-pack for operations managing multiple changes. SSMRC cartridges belong to the separate SSM Plus filtration family.

The Scotsman AP1-P is the right system when a compatible machine needs up to 2.1 GPM and the site calls for chlorine retention, dirt and rust reduction, and phosphate-based scale inhibition. Confirm the equipment match, water conditions, pressure, and service space. Once those requirements line up, it gives the installation a complete, serviceable filtration package built around Scotsman’s treatment approach. If the installation needs greater flow or different treatment capabilities, compare other ice-machine water-filtration systems.
