The Everpure EV933042 (High Flow CSR Twin-MC2) System is a commercial combination filtration system, two MC2 cartridges with an EC210 prefilter and an SR-X scale inhibitor feeder, for fountain, coffee and tea brewer, and ice machine applications. It is built for facility managers, foodservice operators, and installers who need one system to supply all three types of equipment.
This guide covers Everpure EV933042 system installation for a first-time setup, which typically takes 15–30 minutes with standard plumbing tools. Replacing the cartridges on time matters, because an expired cartridge stops filtering and lowers water quality. See the MC2 cartridge replacement guide for the steps.
Safety & Preparation
⚠️ Supply & Operating Limits
Choose the Mounting Location
Choose a wall or mounting surface that can support the system's full operating weight of 42 lbs (19 kg); the shipping weight is 30 lbs (13.6 kg). A 3/4" water line must be available at the location, and no electrical connection is required.
The system measures 25.59" L x 25.8" W x 6.74" D (64.9 x 65.5 x 17.1 cm). Leave 2 1/2" (6.35 cm) of clearance below the cartridges so they can be replaced easily. The 28.5" width shown on the drawing below is measured across the inlet fitting, so allow for that full width at the mounting location.

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. The connection order is covered in Step-by-Step Installation.
🥤 Fountain Outlet
3/4" FNPT. Supplies the fountain equipment.
☕ Ice Machine / Coffee Outlet
3/4" FNPT. Supplies the coffee brewer and ice machine; a tee is required to feed both.

Common Installation Mistakes
Most problems during Everpure High Flow CSR Twin-MC2 system installation come from the mistakes below. Red cards mark mistakes to never make, and amber cards mark ones that are preventable and can be fixed. Each card links to the section that covers the requirement.
A wall or bracket that holds the system when it arrives may not hold it once it fills with water. 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 does not replace disinfection. Confirm your water meets the water-quality notice in Safety & Preparation before connecting the supply.
The system is specified for one MC2 replacement cartridge. Install only the part number listed in When to Replace Your Filter Cartridge.
The fountain equipment has its own outlet, separate from the coffee and ice outlet. If it was connected to the wrong one, shut off the water and reconnect it following step 3 of Step-by-Step Installation.
If the coffee brewer or ice machine was connected without the tee, shut off the water and add it following step 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, and replace any undersized section before connecting the inlet.
The cartridges must hang straight down from the filter head. If the system is tilted or turned, remount it before connecting water, as in step 1 of Step-by-Step Installation.
Without enough open space below the cartridges, each future change becomes difficult. Leave the clearance given in step 1 of Step-by-Step Installation, and remount the system higher if it sits too low.
New cartridges must 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 and fine media particles are expected early in the flush, and the water should run clear by the time it ends.
After the flush, check flow at each connected piece of equipment, look for leaks at the inlet, both outlets and the tee, and confirm the supply pressure holds steady within the range in Safety & Preparation. Compare what you see against the two columns below:
✅ Normal After Installation
🔎 Worth a Second Look
🟢 Ready for use: steady flow at the fountain, coffee and ice equipment, dry connections, and stable pressure.
If anything lands in the right-hand column, review Common Installation Mistakes and Troubleshooting & FAQ. Record the installation date so the first replacement can be scheduled, using When to Replace Your Filter Cartridge.
Official Product Resources
The manufacturer spec sheet covers the system's dimensions, connections, flow rate, and pressure and temperature limits, along with Everpure's installation and operation tips.
When to Replace Your Filter Cartridge
Replace the MC2 cartridges on a regular six-month preventative maintenance program, or sooner if either of the other two conditions below is met:
On a regular preventative maintenance program.
When the system's rated capacity (68,137 L) is reached.
When pressure falls below 10 psi (0.7 bar).
The 18,000-gallon rating covers the system's two MC2 cartridges together, so both are replaced at the same time. The replacement is the Everpure EV961256 (EV9612-56) MC2 cartridge, and each change takes two cartridges. Flush the system after every change, using the same flush as step 6 of Step-by-Step Installation.
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.
How to Maximize the Lifespan of Your Filter
These routine habits keep the system running within its limits and the cartridges replaced 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 clearance from Safety & Preparation free of stored items so cartridges can be changed easily.
- Log every date — record the installation date and each replacement date, and check them against the schedule in When to Replace Your Filter Cartridge.
- Inspect fittings and tubing for leaks — check the inlet, outlets and tee periodically, and remake any connection that is damp.
- Flush after every cartridge change — use the same flush as step 6 of Step-by-Step Installation.
🧽 EC210 prefilter: replace it when it is excessively dirty.
🧪 SS-IMF cartridge: replace it before the Hydroblend™ compound inside is completely used up.
Troubleshooting & FAQ
How long does Everpure EV933042 system installation take?
A first-time installation typically takes 15 to 30 minutes with standard plumbing tools. The full sequence is in Step-by-Step Installation.
Which outlet does fountain equipment use, and which do coffee brewers and ice machines use?
Fountain equipment connects to the fountain outlet, before the SR-X feeder. Coffee brewers and ice machines connect to the ice machine/coffee outlet, after the SR-X feeder. A tee is required on that outlet so it can supply both the coffee brewer and the ice machine.
How many cartridges does the system hold, and which part number replaces them?
The system holds two MC2 cartridges. The replacement is the Everpure EV961256 (EV9612-56) MC2 cartridge, and two are needed for each change.
How often should the cartridges be replaced?
Replace both MC2 cartridges every six months, or sooner if the system reaches its rated capacity or pressure falls below 10 psi. The full schedule and replacement options are in When to Replace Your Filter Cartridge.
How long should the system be flushed?
Run water through the flushing valve at full flow for five minutes, at installation and after every cartridge change. The flush is step 6 of Step-by-Step Installation.
What should I check if a connection leaks?
Shut off the water supply, then recheck and remake the leaking connection, whether it is the inlet, an outlet or the tee. Also confirm the supply pressure is within 10 to 125 psi and non-shock, as listed in Safety & Preparation.
What does low flow or pressure below 10 psi mean?
First confirm the water supply is fully open and the flush is complete. If pressure has fallen below 10 psi, the MC2 cartridges are due for replacement, as covered in When to Replace Your Filter Cartridge.
Does the system need electrical power?
No. The system requires no electrical connection.
Can the system run on hot water?
No. The system is rated for water temperatures of 35 to 100°F, so water above 100°F is outside its limits. The full operating limits are in Safety & Preparation.
What else is replaced besides the MC2 cartridges?
Replace the EC210 prefilter when it is excessively dirty, and replace the SS-IMF cartridge before its Hydroblend™ compound is completely used up. Both are covered in How to Maximize the Lifespan of Your Filter.
