EV943730 Twin System EV943731 Triple System EV943732 Quad System
INTRODUCTION
The Pentair® Everpure® Endurance High-Flow Filtration systems are designed to treat up to 200,000 gallons of water per SEN cartridge
change cycle. The systems use a pretreatment Hollow Fiber Ultralter (HFUF), 2, 3 or 4 ne lter cartridges and a 2SR-BW scale inhibiting
cartridge.
INSPECTION
Before mounting the Pentair Everpure Endurance High-Flow system, use the table and illustration to verify the parts and quantities. If any
parts are missing, contact Customer Service at 630.307.3000 (Main) / 800.942.1153 (US only) or email at [e-mail].

MOUNTING & CONNECTION CONSIDERATIONS
The location selected for system installation should allow for:
• Adequate space for “in” and “out” water line connections.

OPERATING SPECIFICATIONS
• Temperature Limits: 35-100°F (2-38°C)
• Pressure Limits: 10-100 psi (0.689-6.9 bar)

INSTALLATION PROCEDURE
NOTE: For installations in Australia and New Zealand, product must
be installed with a backow prevention device in accordance with
AS/NZS 3500 and AS/NZS 2845.1.
1. The predrilled mounting holes in the bracket can be used as a
guide. The holes are on 16" centers. Mark and insert anchors or
screws in the wall.
NOTE:The large pretreatment cartridge can be removed from
the bracket and mounted separately.
2. Follow steps 3-6 only if the pretreatment cartridge (Pleated
Endurance HF) is going to be mounted separately. Otherwise,
proceed to Step 7.
3. Disconnect the hose between the pretreatment head and the
manifold.
4. Unscrew the two screws that hold the pretreatment bracket to
the main bracket.
Remove Screws

5. Secure the pretreatment bracket with the head to the desired
location. Use the screw holes from the previous step for mounting.
6. Use a section of 3/4" I.D. tubing to reconnect the pretreatment
outlet to the inlet of the manifold. The pretreatment outlet cannot
be more than 25 feet from the manifold. The tubing should have
clamps at each end with no sharp bends or kinks.
NOTE:Use tubing that is opaque and suitable for use with
beverages.
7. Mount the manifold using four (4) screws in the bracket mounting
holes.
8. Connect the treated water outlet port to the equipment being
served (Figure 2).

9. Connect the untreated water to the inlet tting on the
pretreatment head (Figure 2).
10. Attach 3/8" I.D. tubing to the ush valve tting (Figure 2). Run the
other end of the tubing to a drain.
NOTE: Some plumbing codes require an air gap at the drain
termination.
11. The 2SR-BW does not have a shut off valve. Attach 1/2" I.D.
tubing to the outlet barb of the 2SR-BW head. Route the other
end of the tubing to the equipment being served. Both ends of
the tubing should be clamped to the hose barb.
12. Turn off the ow valves for the inlet, ush and scale inhibitor
cartridge (2SR-BW) (Figure 2).
13. Check to be sure the O-ring on the pretreatment housing is
suciently lubricated. Use a good grade of silicone lubricant,
if needed. Unwrap the pretreatment cartridge. Position the
pretreatment cartridge on guide seat in the bottom of the bowl.
Then thread the bowl into the head by hand. Use a sump wrench
to lightly tighten the bowl onto the head. This bowl can be
tightened further if leaks occur later. The two O-rings at the top
of the cartridge will t snuggly into the head.
NOTE:To install the carbon lter and scale inhibitor cartridges,
align the cartridge lug with the label, push upward and
rotate to the right (cw) until rotation stops.
14. Install only genuine Pentair Everpure carbon lter cartridge(s)
into the lter head(s) following directions on the SEN
cartridge label or as shown in the Cartridge Change Procedure
illustrations. Install the scale inhibitor cartridge (2SR-BW).
CAUTION: Unused manifold ports must be plugged. Any ports
that are not plugged will leak.
15. Open the ush valve then turn on the inlet water. Open the valve
on the pretreatment head. Water will ush to the drain at full
force. Allow the system to ush for ve (5) minutes. This will set
the ltering media and purge any air.
16. After ushing, close the ushing valve. The pressure gauge will
show the system pressure when the cartridges are new.
17. Open the valve for the scale inhibitor cartridge. The Endurance
High Flow system is now ready for use.
FLUSHING
For maximum life, all carbon lter cartridges must be ushed for
ve minutes at full ow before use. FLUSH ALL CARTRIDGES AFTER
EACH CARTRIDGE CHANGE.
If the new cartridges have been adequately ushed and the
pressure gauge needle registers inadequate pressure; you may be
experiencing insucient water pressure or some restriction may
exist in the inlet water line. In either case, the water pressure needs
to be improved to achieve optimum lter life.
If the system is switched off for more than 48 hours, ush for at
least two (2) minutes.
CARTRIDGE CHANGE DETERMINATION
Replace all lter cartridges annually, when capacity is reached or
when water pressure or ow to equipment becomes inadequate. All
cartridges on multiple cartridge systems should be changed at the
same time.
The system pressure gauge provides a quick, simple means of
determining when the lter cartridge(s) should be checked. It is
installed on the system outlet manifold. The gauge can be used
to monitor both dynamic (owing) and static (line) pressure. The
cartridge(s) should be changed when the pressure gauge is in the
red area while the equipment is in operation, and the needle shows
adequate line pressure between cycles. Observe the needle during
the next equipment on cycle. If the needle registers adequate
pressure, it can be assumed that the temporary low-pressure
condition was caused by a brief power failure or other incoming
pressure disruption. If the low pressure condition is not due to an
external condition, check/change the pretreatment lter rst. If the
low pressure condition is still not corrected, change the SEN carbon
lter cartridges.

NOTES
Not for residential use. For food service applications only.
Check for compliance with state and local laws and regulations.
Do not use with water that is microbiologically unsafe or of unknown
quality without adequate disinfection before or after the system.
Systems certied for cyst reduction may be used on disinfected
waters that may contain lterable cysts.
The term "bacteriostatic" indicates that the system limits the
passage or growth of bacteria that may already exist in the incoming
water. It does not mean that the water leaving the system is safer to
drink than the water entering the system.
WARNING: FOR CORRECT OPERATION OF THIS APPLIANCE IT IS
ESSENTIAL TO OBSERVE THE MANUFACTURER’S INSTRUCTIONS.
NSF/ANSI Standard 53 certied to reduce cysts such as
Cryptosporidium and Giardia by mechanical means.
Proprietary Micro-Pure II ltration media effectively inhibits the
growth of bacteria on the lter media that can decrease product life.
