The Everpure EV929301 Coldrink/Insurice Manifold with 10" Prefilter is a commercial-grade filter head that holds Everpure Quick-Change cartridges and comes with an EC110 prefilter cartridge. It is built for owners and facility managers setting up filtration for fountain beverages, ice machines, and coffee and tea brewers.
Everpure EV929301 system installation takes an estimated 15–30 minutes for a first-time setup. Everything from choosing a location to flushing the new system is covered here. Once the system is in service, replace cartridges on time because an expired cartridge stops filtering and water quality drops.
Safety & Preparation
Choose the Mounting Location
The system measures 14.254" W x 14.877" H x 6.13" D (36.20 x 37.79 x 15.57 cm) and has a shipping weight of 10 lb (4.5 kg). Choose a mounting surface that can support the system's weight while it is operating. Leave 2 1/2" (6.35 cm) of open space below the cartridge so it can be removed and replaced. Do not install the system anywhere it could be exposed to freezing temperatures.

🔍 Before you start: confirm your water supply falls within these limits:
The inlet is 3/4" FNPT and the outlet is 3/8" FNPT. Check both against your supply line and the equipment line before you begin. The manifold is for use with Everpure Quick-Change cartridges.

Common Installation Mistakes
The cards below are sorted by how serious each mistake is. Red cards are mistakes to avoid entirely. Amber cards are mistakes you can still correct, and each one gives the fix. When a requirement is covered in another section, the card links to it.
The system is rated for a set operating pressure and water temperature range. Confirm your supply stays inside both limits listed in Safety & Preparation before you put the system into service.
The manifold head is designed only for Everpure Quick-Change cartridges. Cartridge compatibility is covered in Safety & Preparation.
The bracket has to carry the system while it is full of water and running. If you are unsure whether a wall or surface can handle that, pick one that clearly meets the requirement in Safety & Preparation.
Unheated rooms, exterior walls, and other cold spots put the system at risk. Choose a location that stays above freezing all year, as described in Safety & Preparation.
If the bracket is tilted, shut off the water and remount it so the system sits vertically with the cartridges hanging straight down, as in Step-by-Step Installation.
Without open space underneath, the cartridge can't come out at replacement time. Raise the bracket or clear the area until it meets the clearance in Safety & Preparation.
The supply line goes to the inlet, and the outlet feeds your equipment. The two ports are different sizes, listed in Safety & Preparation. If the lines are reversed, shut off the water and reconnect them correctly.
The system needs to be flushed before it goes into service. If this step was missed, run the flush now using the time in What to Expect After Installation.
What to Expect After Installation
Start-Up: Flush the System
With both cartridges installed and the water on, flush the system by running water through it for 5 minutes. If your unit has the optional flushing valve, use it for this step. During the flush and again once it ends, check the inlet and outlet connections for leaks.
Next, read the built-in pressure gauge, which helps you monitor proper flow. The reading should sit within the operating pressure range in Safety & Preparation. 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 connections stay dry, the gauge reads within range, and flow is steady. If anything matches the right-hand column, go to Troubleshooting & FAQ. Going forward, the gauge is also your early warning for reduced flow, as covered in How to Maximize the Lifespan of Your Filter.
When to Replace Your Filter Cartridge
Replace cartridges once a year, or sooner if either sign below appears first:
When a cartridge reaches its rated capacity, replace it, even if a full year hasn't passed.
A noticeable drop in flow means it's time to replace the cartridge ahead of schedule.
The standard interval, even if neither sign has shown up yet.
🔁 Both cartridges: the schedule applies to every cartridge in the system, the EC110 prefilter and the Quick-Change cartridge alike.
The replacement prefilter listed on the spec sheet is the Everpure EC110 (EV953412), a 10-micron sediment prefilter cartridge sold here as a 12-pack. To set it and forget it, an optional subscription delivers a 12-pack every 12 months, so a new prefilter is on hand whenever the schedule or a sign above calls for one. The subscription only keeps you stocked. The signs and schedule above still decide when each cartridge comes out.
How to Replace the Cartridge
- Shut off the water to the system. If your unit has the optional built-in shut-off valve, close it.
- Remove the used cartridge, using the open space below it.
- Install the new cartridge.
- Turn the water back on and flush as described in What to Expect After Installation.
How to Maximize the Lifespan of Your Filter
A few routine habits keep the EV929301 working as designed and make each cartridge change go faster:
- Watch the pressure gauge: a falling reading is an early sign of reduced flow, so you can plan the next cartridge change before flow suffers.
- Protect the system from freezing: if conditions around the installation change, make sure it still meets the location requirements in Safety & Preparation.
- Keep the space below the cartridge open: don't let storage or equipment crowd the clearance needed to remove it.
- Check for leaks: inspect the fittings and tubing periodically for drips or dampness.
- Clean the outside gently: wipe exterior surfaces with a mild, non-abrasive cleaner.
- Expand without starting over: the box bracket's modular design lets you add components later without taking the system apart.
Replace each cartridge before it falls behind, following When to Replace Your Filter Cartridge.
Troubleshooting & FAQ
How long does Everpure EV929301 system installation take?
An estimated 15 to 30 minutes for a first-time installation. The full sequence is in Step-by-Step Installation.
Which cartridges fit the EV929301?
The manifold head takes Everpure Quick-Change cartridges, and the prefilter position takes the EC110 prefilter cartridge. Compatibility is covered in Safety & Preparation, and the EC110 replacement is in When to Replace Your Filter Cartridge.
Do I need a separate mounting plate?
No. The system comes with a mounting box bracket and screws, so no extra mounting plate is required.
What pressure and temperature limits apply?
Operating pressure must stay between 10 and 125 psi (non-shock), and water temperature between 35 and 100°F. The full supply requirements are in Safety & Preparation.
How long should I flush the system after installation?
Run water through the system for 5 minutes. The leak, gauge, and flow checks that follow are in What to Expect After Installation.
Why is flow low or the gauge reading low, and what should I check?
Check the water supply first. Make sure it is fully on and that the pressure feeding the system is within the operating range. If the supply is fine, slowed flow is a sign the cartridges need replacing, as covered in When to Replace Your Filter Cartridge.
What should I check if a connection leaks?
Shut off the water, confirm the supply line is on the inlet and the equipment line is on the outlet, and reseat the leaking fitting. Then turn the water back on and check the connection again.
When should I replace the cartridges?
Once a year, or sooner if a cartridge reaches its capacity or flow slows down. The full guidance is in When to Replace Your Filter Cartridge.

Auto-delivery sends an EC110 12-pack every 12 months, so a replacement is already on hand when it's time for a change.
Conclusion
Installing the EV929301 comes down to five steps in order. Confirm the location and clearance, mount the box bracket vertically, connect the inlet and outlet, install both cartridges, and flush. Before the system goes into service, check that the connections stay dry, the gauge reads within range, and flow holds steady.
After that, the main task is replacing cartridges on time. Keep an eye on the pressure gauge, and follow the schedule and signs in When to Replace Your Filter Cartridge. The optional subscription keeps EC110 prefilters on hand, so the next change never has to wait on an order.
