The Everpure EV943710 (High Flow CSR Quad-MC2) System is a multi-cartridge commercial system that supplies fountain, coffee and tea, and ice equipment from a single unit. It is built for foodservice operators and the installers handling Everpure EV943710 system installation.
This guide covers first-time installation, which takes an estimated 15–30 minutes. To keep water quality consistent, replace the cartridges on schedule. For the replacement procedure, see our MC2 cartridge replacement guide.
Safety & Preparation
Choose the Mounting Location
Pick a wall or mounting surface that can safely support the system's full operating weight of 58 lbs (26.3 kg). The system measures 25.69" L x 34" W x 6.75" D (65.28 x 86.4 x 17.1 cm), so confirm the space fits that footprint plus the clearance below the cartridges described in Step-by-Step Installation. A 3/4" water line must be available at the location.

🔍 Operating limits: supply pressure of 10–125 psi (0.7–8.6 bar), non-shock, and water temperature of 35–100°F (2–38°C). No electrical connection is required.
Plan the Equipment Connections
The system has a 3/4" FNPT inlet and two 3/4" FNPT outlets. Decide which equipment runs to each outlet before you start plumbing:
🥤 Fountain Outlet
Fountain equipment connects here, ahead of the SR-X feeder.
☕ Ice Machine / Coffee Outlet
The coffee brewer and ice machine connect after the SR-X feeder. A tee is required to supply both.

Step-by-Step Installation
Common Installation Mistakes
The mistakes below account for most setup problems. Red cards mark mistakes to never make, and amber cards mark ones that are easy to prevent and can be corrected. Each card links to the section that covers the requirement.
The system is considerably heavier in operation than on the shelf, so a wall or bracket that holds it empty may not hold it filled. Confirm the surface is rated for the full operating weight listed in Safety & Preparation before mounting.
Supply pressure and water temperature both have set ranges, and the pressure must be non-shock. Check your supply against the operating limits in Safety & Preparation before putting the system into service.
The system must hang vertically with the cartridges pointing down. If it is tilted or turned, remount it before connecting water, as in step 1 of Step-by-Step Installation.
Without open space under the cartridges, each future change becomes difficult. Leave the clearance given in step 1 of Step-by-Step Installation, and remount the system if it sits too low.
The coffee brewer and ice machine belong after the SR-X feeder, on a tee, and not ahead of it with the fountain equipment. If they are connected in the wrong place, reconnect them following steps 3 and 4 of Step-by-Step Installation.
The system is designed for a specific water line size. Confirm your supply line matches the size listed in Safety & Preparation before connecting the inlet.
New cartridges need to be flushed before the system goes into service. If the flush was skipped, run it now for the time given in step 6 of Step-by-Step Installation.
What to Expect After Installation
Complete the flush in step 6 of Step-by-Step Installation before putting the system into service. Air sputtering and fine carbon particles are expected early in the flush and should clear before it ends.
Once the flush is done, check the inlet, tee and outlet connections, then run each connected machine and compare what you see against the two columns below:
✅ Normal After Installation
🔎 Worth a Second Look
🟢 Ready for service: the system is ready once the flush is complete, every connection is dry, and the fountain, coffee and ice equipment all dispense normally.
If anything lands in the right-hand column, see Troubleshooting & FAQ. Record the installation date so you can track the schedule in When to Replace Your Filter Cartridge.
Official Product Resources
The specification sheet summarizes key tips and ratings; the installation and operation guide provides the full step-by-step procedure, connection details, and flush instructions.
When to Replace Your Filter Cartridge
Replace the MC2 cartridges as soon as any one of these three conditions is met, whichever comes first:
On a regular six-month preventative maintenance program.
When the system's rated capacity (136,274 L) is reached.
When pressure falls below 10 psi (0.7 bar).
🧪 SS-IMF cartridge: replace it before the Hydroblend™ compound inside is completely used up.
🧽 EC210 prefilter: replace it when it is excessively dirty.
The system takes four Everpure EV961256 MC2 cartridges, each rated for 9,000 gallons, so every change involves four cartridges at a time. To stay on the six-month schedule without tracking dates, the filter subscription is a set-it-and-forget-it option, with cartridges delivered automatically every six months.
Flush the system after every cartridge change, using the same flush as step 6 of Step-by-Step Installation.
How to Maximize the Lifespan of Your Filter
These routine habits keep the system operating as installed and the cartridges changing on time:
- Stay within the operating limits — keep supply pressure and water temperature inside the ranges in Safety & Preparation.
- Keep the space below the cartridges open — leave the 2 1/2" clearance free of stored items so cartridge changes stay easy.
- Flush after every cartridge change — run the same flush used at installation, as in When to Replace Your Filter Cartridge.
- Replace the prefilter and SS-IMF cartridge on their own conditions — replace each when its condition in When to Replace Your Filter Cartridge is met, rather than waiting for the full MC2 interval.
- Check the connections periodically — look for leaks at the inlet, tee and outlets, and recheck any connection that is damp.
- Use suitable water — keep the system on water that meets the water-quality notice in Safety & Preparation.
Troubleshooting & FAQ
What equipment can the EV943710 system support?
It can supply up to four carbonators combined with a four-pot coffee brewer and a 1,200 lb (544.3 kg) ice machine.
A connection is leaking. What should I check?
Shut off the water supply first. Then recheck the leaking connection, whether it is the inlet, the tee or one of the outlets, and remake it according to the packaged installation instructions. Also confirm the supply pressure is between 10 and 125 psi (0.7–8.6 bar) and non-shock.
Why is flow low after installation?
Confirm the water supply is fully open and the flush has been completed. Then check the supply pressure, because the system requires at least 10 psi (0.7 bar) to operate. The flush is step 6 of Step-by-Step Installation.
How long should the system be flushed, and why?
Run water through the flushing valve for five minutes at full flow, both at installation and after every cartridge change. The flush purges trapped air and fine carbon particles from the new cartridges before the system goes into service.
How often are the cartridges replaced?
Replace the four MC2 cartridges every six months, when the system reaches its rated 36,000 gallons, or when pressure falls below 10 psi, whichever comes first. Replace the SS-IMF cartridge before its Hydroblend™ compound is used up, and the EC210 prefilter when it is excessively dirty. Replacement options are in When to Replace Your Filter Cartridge.
Can I replace a single cartridge instead of all four?
Yes. The EV961256 MC2 cartridge is sold individually, so a single cartridge can be replaced. On this four-cartridge system, the cartridges are typically replaced together on the same schedule.
Which cartridges and parts are included?
The system ships with four MC2 cartridges (EV961256), the EC210 prefilter cartridge (EV953426), the SS-IMF scale control cartridge (EV979932) and the installation instructions.
Can the system be used with unsafe water or water of unknown quality?
No. Do not use it with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system.

Conclusion
Everpure High Flow CSR Quad-MC2 system installation follows a short sequence: mount the system vertically with clearance below the cartridges, connect the inlet, run the fountain equipment to its outlet, and connect the coffee brewer and ice machine on a tee after the SR-X feeder. Confirm the cartridges are seated, then check every connection for leaks and complete the flush before putting the system into service.
From there, replace the cartridges on the schedule in When to Replace Your Filter Cartridge, or let the subscription handle the timing. Record each change, and use our MC2 cartridge replacement guide for the procedure.
