The Everpure EV932421 (Insurice Single PF-i20002) Filtration System is a single-cartridge system with an integrated 20-inch EC210 prefilter, rated for 9,000 gallons and certified to NSF/ANSI 42 and 53. Sized for cubers up to 750 lbs/day and flakers up to 1,500 lbs/day, it filters water for commercial ice machines used by food service operators and facility managers.
This guide covers a first-time Everpure EV932421 system installation, which takes an estimated 15–30 minutes. After setup, keep the cartridge on schedule with our Everpure EV961222 Filter Replacement Guide, because a cartridge past its service life stops filtering and lets water quality drop.
Safety & Preparation
Choose the Mounting Location
Pick a surface strong enough for the system's 19 lb (8.6 kg) operating weight, with room for its 25.33" H x 14.15" W x 6.47" D footprint. Keep 2-1/2 inches (6.35 cm) of open space below the cartridge so it can be lowered out at each change, and choose a spot close to a drain for the flushing valve.
Insurice Single PF-i20002 System Dimensions
🔍 Before you start: confirm the site, the water supply, and the ice machine meet these requirements:
Feed the inlet from a 3/4" cold water line, and plan a 3/8" outlet run to the ice machine. The system itself needs no electrical connection.

⚠️ Safety Precautions
Step-by-Step Installation
Common Installation Mistakes
Red cards are mistakes to avoid completely. Amber cards are mistakes you can correct after the fact, with the fix included. Where another section covers a requirement in detail, the card links to it.
The spec sheet rules out saddle valves and any connection to a water-cooled condenser. To avoid it, use threaded fittings on a supply line sized as listed in Safety & Preparation, and run the outlet only to the ice machine.
Flow above the rated maximum, or pressure and temperature outside the rated range, puts the system outside what it is built for. To avoid it, check the ice machine and the water supply against the limits in Safety & Preparation before you install.
Every new cartridge must be flushed before it goes into service. To avoid it, run the full flush in step 6 of Step-by-Step Installation before you restore power to the ice machine.
Unsealed threads can seep, and tightening without a backup wrench puts stress on the system components. To fix it, shut off the water, open the joint, apply NSF-approved pipe dope or Teflon tape, and retighten while holding the fitting with a backup wrench.
The flush needs a path to the drain, and a valve left open sends water to the drain instead of the ice machine. To fix it, run tubing from the flushing valve to a drain before flushing, and close the valve as soon as the flush ends.
A surface that can't carry the full operating weight, a system that isn't vertical, or too little room below the cartridge all cause problems now and at every change. To fix it, shut off the water and remount through the bracket's predrilled holes to meet the requirements in Safety & Preparation.
A cartridge stopped short of its full turn won't seal properly at the head. To fix it, shut off power and water, open the flushing valve to relieve pressure, then realign and turn the cartridge as in step 5 of Step-by-Step Installation.
What to Expect After Installation
Check for Leaks
With the water on, check every connection, the cartridge head, and the prefilter for leaks. Confirm the flushing valve is fully closed after the flush in step 6 of Step-by-Step Installation. Some air sputtering, slightly cloudy water, or fine media particles are normal at first and clear during the flush.
Confirm Flow and Pressure
With the ice machine running, confirm it gets full, steady flow and that the outlet pressure gauge needle stays out of the red area. A needle in the red during operation is a replacement sign, explained in When to Replace Your Filter Cartridge. Use the two columns below to check what you see:
✅ Normal After Installation
🔎 Worth a Second Look
If flow stays low or something leaks, recheck that the cartridge is locked in as in step 5 and that the EC210 prefilter is installed. For anything else in the right-hand column, see Troubleshooting & FAQ.
The system is ready for service once the flush is complete, every connection stays dry, and flow is normal. Record the installation date so you can track the schedule in When to Replace Your Filter Cartridge.
Official Product Resources
For Everpure EV932421 system installation, the EV9324-21 spec sheet lists this system's ratings, dimensions, and connections, along with Pentair's installation and operation tips. Pentair's Insurice installation and operation guide covers the full Insurice line, so follow the Single system entries.
When to Replace Your Filter Cartridge
Replace the i20002 cartridge at whichever of these comes first:
The preventive maintenance schedule, even if no other sign has appeared.
The cartridge's rated capacity has been reached.
Pressure under 10 psi (0.7 bar), shown by the gauge needle in the red while the ice machine runs.
🔍 EC210 prefilter: inspect it periodically and replace it once dirt has reached its inner core. The EC210 6-pack is listed below.
Flush every new cartridge after a change, as in step 6 of Step-by-Step Installation. The replacement cartridge is the Everpure EV961222 (EV9612-22) i20002, which BFS lists as compatible with the EV932421. It installs the same way as in step 5.
Choose the 1-pack for a single replacement, the 6-pack to stock ahead, or the open-box 1-pack for the same cartridge at a lower price. To set it and forget it, the subscription delivers a 1-pack every 6 months, matching the replacement schedule.
How to Maximize the Lifespan of Your Filter
These habits help the Single PF-i20002 run as designed between cartridge changes:
- Keep the system accessible: don't let storage or equipment crowd the open space below the cartridge, so changes stay quick.
- Stay within the rated limits: keep supply pressure, temperature, and flow inside the ranges in Safety & Preparation.
- Check the EC210 prefilter on a schedule: a loaded prefilter passes sediment on to the i20002 and shortens its life. Before you replace it, open the flushing valve to relieve pressure.
- Watch the outlet pressure gauge: glance at it during normal operation to spot a pressure drop early.
- Inspect for leaks: look over the fittings and tubing during routine checks, and reseal any connection that shows moisture.
- Clean the exterior gently: wipe the system with a mild, non-abrasive cleaner.
- Log and flush every change: record each replacement date against the schedule in When to Replace Your Filter Cartridge, and flush every new cartridge as in step 6 of Step-by-Step Installation.
Troubleshooting & FAQ
How long does Insurice Single PF-i20002 system installation take?
An estimated 15 to 30 minutes for a first-time setup. The full sequence is in Step-by-Step Installation.
Do I need a plumber to install the system?
Pentair recommends a licensed plumber, and the installation must meet state and local plumbing codes.
Why is the system leaking at the cartridge head, a fitting, or the prefilter?
At the cartridge head, the cartridge is usually not locked in. Shut off the ice machine and the water, open the flushing valve to relieve pressure, then line up the lug with the label and turn the cartridge right 90 degrees until it stops. At a fitting, shut off the water, reseal the threads with NSF-approved pipe dope or Teflon tape, and retighten with a backup wrench. At the prefilter, shut off the water, relieve pressure, and check that the EC210 is installed correctly.
Why is flow low after installation?
First confirm the flushing valve is fully closed. Then check that the i20002 cartridge is locked in, the EC210 prefilter is installed, and nothing is restricting the inlet line.
What should I do about air sputtering or cloudy water?
Both are normal on a new installation and clear during the flush. Let the flush run the full five minutes at full flow before you close the flushing valve.
Why does the pressure gauge read low or sit in the red?
Right after installation, check that the flushing valve is closed and the cartridge is locked in. In normal use, a needle in the red while the ice machine runs, with adequate line pressure between cycles, means the cartridge needs replacing.
How often should I replace the cartridge and the EC210 prefilter?
Replace the i20002 cartridge on the six-month schedule, or sooner if a replacement sign appears. Replace the EC210 when dirt reaches its inner core. Full guidance is in When to Replace Your Filter Cartridge.
Which replacement cartridges fit this system?
The main cartridge is the Everpure EV961222 (EV9612-22) i20002. The prefilter takes the EC210 (EV9534-26).
What is the difference between the Single PF-i20002 and the Single i20002?
The PF-i20002 adds an integrated EC210 prefilter ahead of the main cartridge. Both systems use the same i20002 cartridge.
Will the system work with my ice machine?
Check your machine's required flow against the system's 1.67 gpm maximum service flow. The spec sheet sizes it for cubers up to 750 lbs/day and flakers up to 1,500 lbs/day.
Why is the flush required?
Pentair requires every new cartridge to be flushed before it goes into service. The flush sets the filter media and purges air and fine particles.
