The Everpure EV932402 (Insurice Twin-i20002) System is a twin-cartridge filtration system for commercial ice machines. It is built for foodservice operations, with both i20002 cartridges mounted on a single manifold.
Everpure EV932402 system installation takes an estimated 15–30 minutes for a first-time setup, and this guide walks through each step from mounting to start-up. After installation, replace the cartridges on time with our Everpure EV961222 Filter Replacement Guide, because an expired cartridge stops filtering and water quality drops.
Safety & Preparation
Choose the Mounting Location
The mounting surface must hold the system's full operating weight of 18 lb (8.1 kg) and fit its 25.26" H x 16.6" W x 5.5" D footprint. Pentair's installation guide lists the Twin system at 19 lb (8.5 kg), so choose a surface that can carry at least that. Leave 2-1/2 inches (6.35 cm) of open space below the cartridges so they can come out for changes. Pick a spot near a drain for the flushing valve, with room to run the inlet and outlet lines.
Insurice Twin-i20002 System Dimensions
🔍 Before you start: confirm your water supply and ice machine fall within these limits:
The inlet is 3/4" MNPT and the outlet is 3/4" FNPT, sized for a 3/4" water line. Check both against your existing line before you begin.

Common Installation Mistakes
Red cards mark mistakes to avoid entirely. Amber cards mark mistakes you can fix after the fact, and each one explains how. When another section covers a requirement in full, the card links to it.
The spec sheet rules out saddle valves and says not to connect the system to a water-cooled condenser. Run the outlet to the ice machine's water inlet only, and supply the system from a 3/4-inch line with threaded fittings that match the connections in Safety & Preparation.
The spec sheet says the service flow must not exceed its rated maximum. Before you install, check that your ice machine stays within the flow limit and sizing in Safety & Preparation.
New cartridges must be flushed before they go into service. Run tubing from the flushing valve to the drain before the first flush, keep the ice machine off until the flush is finished, and close the valve afterward. If the valve was left open, close it now. The flush is covered in What to Expect After Installation.
Every threaded connection needs NSF-approved pipe dope or plumber tape. Hold each fitting with a backup wrench while you tighten it, so the system components aren't put under stress. If a joint seeps, shut off the water, disconnect it, apply sealant, and reconnect it.
The system is heavier full of water than it is in the box, the cartridges must hang straight down, and they need open space below to come out for changes. If the mounting falls short on any of these, shut off the water and remount the system through the bracket's predrilled holes to meet the requirements in Safety & Preparation.
Each head needs its own cartridge, lined up and turned the full 90 degrees. If a cartridge isn't seated, shut off power and water and open the flushing valve to relieve pressure. Then realign the lug with the head label and turn the cartridge until rotation stops, as in step 5 of Step-by-Step Installation. Fill any empty head before you turn the water back on.
What to Expect After Installation
Start-Up: Flush the System
With both cartridges installed and the water on, open the flushing valve fully and run water through the system at full flow for five minutes. Then close the valve. The flush sets the filter media and purges air and fine particles, so some sputtering at the drain early on is normal. Once the valve is closed, check every fitting and both cartridge heads for leaks.
Read the Outlet Pressure Gauge
While the ice machine runs, the needle should show adequate pressure. If the needle sits in the red during operation but shows adequate line pressure between cycles, it is time to replace the cartridges, as covered in When to Replace Your Filter Cartridge. A single low reading can come from a brief power failure or a short drop in incoming pressure, so watch the next run cycle before you replace anything. Use the two columns below to sort what you see:
✅ Normal After Installation
🔎 Worth a Second Look
The system is ready for use once the flush is complete, the fittings and cartridge heads stay dry, the gauge reads adequate pressure, and the ice machine is running normally. If anything matches the right-hand column, go to Troubleshooting & FAQ.
Official Product Resources
For Everpure EV932402 system installation, Pentair's Insurice installation and operation guide is the official reference. It covers every Insurice system size, so follow the Twin entries. The EV9324-02 spec sheet lists this system's flow rate, capacity, operating limits, dimensions, and connections.
When to Replace Your Filter Cartridge
Replace both cartridges on a six-month preventive maintenance schedule. Replace them sooner if either sign below shows up first:
The standard replacement schedule, even if neither sign has appeared yet.
18,000 gallons for the system, which is 9,000 gallons per cartridge.
A drop below 10 psi (0.7 bar) means the cartridges need replacing ahead of schedule.
🧭 Outlet pressure gauge: the gauge on the manifold shows when pressure has dropped, so you don't have to guess. How to read it is covered in What to Expect After Installation.
Replace both cartridges at the same time, and flush the system after every change as described in What to Expect After Installation. To set it and forget it, an optional 12-month subscription delivers a 6-pack once a year, enough for three two-cartridge changes. The subscription only keeps you stocked. The schedule and signs above still decide when the cartridges come out.
The replacement cartridge is the Everpure EV961222 (EV9612-22) i20002, which the spec sheet names for this system. Each head takes one, so every change uses two. It has a quick-change, quarter-turn design and seats the same way as in step 5 of Step-by-Step Installation. The open-box option is the same unused cartridge at a discounted price. Its listing states it has no factory warranty and is not returnable.
How to Maximize the Lifespan of Your Filter
These routine habits keep the Twin-i20002 running as designed and make cartridge changes faster:
- Stay within the rated limits: water running above the flow limit, or outside the pressure and temperature range, shortens cartridge life. The limits are in Safety & Preparation.
- Check the pressure gauge on a routine: regular looks during normal operation help you catch a pressure drop early.
- Keep the space below the cartridges open: don't let storage or equipment crowd the clearance needed to lower the cartridges out.
- Watch for leaks: look over the fittings and tubing during routine checks, and reseat or reseal any connection that shows moisture.
- Clean the exterior gently: wipe the system down with a mild, non-abrasive cleaner.
- Keep a replacement log: record the date of each change so the next one is easy to plan.
- Leave room for a prefilter: if possible, keep about 6 inches free on each side of the system in case poor water quality later calls for an optional prefilter.
Replace both cartridges on time, following the schedule and signs in When to Replace Your Filter Cartridge.
Troubleshooting & FAQ
How long does Everpure Insurice Twin-i20002 system installation take?
An estimated 15 to 30 minutes for a first-time installation. The full sequence is in Step-by-Step Installation.
Do I need a professional to install the system?
A licensed plumber is recommended. The installation must also comply with state and local plumbing codes.
Will the system suit my ice machine?
The spec sheet sizes it for cubers up to 1,450 lbs/day and flakers up to 2,200 lbs/day. Compare your machine's daily ice production with those figures, and check the full operating limits in Safety & Preparation.
Why is a cartridge head leaking?
The cartridge is usually not fully seated. Shut off power to the ice machine and the inlet water, then open the flushing valve to relieve pressure. Reseat the cartridge by aligning the lug with the head label, pushing it in firmly, and turning it right the full 90 degrees until rotation stops.
Why is flow or pressure low after installation?
Check that the flushing valve is closed first. Then confirm both cartridges are locked in, neither head was left empty, and nothing is restricting the inlet water line.
How long should I flush the system after installation?
Five minutes at full flow, with the flushing valve fully open. Then close the valve and check for leaks. The full start-up checks are in What to Expect After Installation.
When should I replace the cartridges?
Replace both on the six-month preventive maintenance schedule, or sooner if capacity is reached or pressure falls below 10 psi. The full guidance is in When to Replace Your Filter Cartridge.
Which cartridge fits the Twin-i20002?
The Everpure EV961222 (EV9612-22) i20002 cartridge. Each head takes one, so every change uses two.
Why are both cartridges replaced together?
Pentair specifies that all cartridges on a multiple-cartridge system be changed at the same time.
What does the pressure gauge reading mean?
While the ice machine runs, the needle should show adequate pressure. A needle in the red during operation, with adequate line pressure between cycles, means it is time to replace the cartridges.
