INSTALLATION PROCEDURE (continued)
NOTE: To install the EverpureSEN carbon lter and 2SR-BW scale
inhibitor cartridges, align the cartridge lug with the label, push
upward and rotate to the right until rotation stops.
11. Install only genuine EverpureSEN 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 2SR-BW scale inhibitor cartridge.
CATION: Unused manifold ports must be plugged. Any ports that are
not plugged will leak.
NOTE: The storage tank mounts above the manifold assembly. It
must be mounted with the water tank valve at the bottom. Failure to
mount tank with water valve down will void the warranty.
12. A short piece of new 3/4" tubing (15 in./38.1 cm long) is provided
with the system. Attach the tubing to the barb connection on the
exit (right) side of the head for the Pentair EverpureEndurance
SC HFUF ("Figure 1"). Use one of the supplied Oetiker clamps to
secure.
13. Mount the tank to allow a connection with the 3/4" tubing. The
mounting holes will accept a 1/4" diameter lag bolt or screw.
14. Connect the 3/4" tubing to the barb connection on the storage
tank. Use one of the supplied Oetiker clamps to secure.
15. Connect the incoming water supply to the inlet valve.
16. There are four (4) union connections above the controller that may
loosen during shipping. Two (2) for the solenoid valve and two (2) for
the turbine. Tighten each one by hand to secure the connection.
17. The storage tank air pressure must be set to 20 psi
(1.37bar/137.8 kPa). Unscrew the valve cap at the top of the
tank. Open the tank ball valve at the bottom of the tank and
open a single valve downstream to release pressure in the tank.
Measure the internal pressure with an air gauge. Add or release
pressure as needed until the pressure reads 20 psi (1.37 bar/137.8
kPa). Then screw valve cap back on.
NOTE: The precharge pressure should be zero when initially
checked. Charge the tank to the specied pressure, 20 psi
(1.37bar/137.8 kPa). It is advisable to check the precharge pressure
again in the very near future to verify the precharge pressure has
not changed. Loss of precharge pressure indicates a leak at the
Schrader® valve, bladder or tank/seal.
NOTE: Check storage tank pressure every 6-12 months during
regular cartridge change. If the tank pressure is below 20 psi
(1.37bar/137.8kPa), recharge and check pressure more frequently.
18. Connect carbonated and non-carbonated beverage outlet(s).
WARNING: HFUF Flush Line peak ow is 12-15 gpm (45-57 Lpm).
Mount discharge above drain with air gap that meets local and
national standards. During start-up, check if drain capacity and ow
are adequate to prevent ooding.
START-UP
At this point, the EverpureEndurance SC High-Flow system should
be completely installed with the exception of the scale inhibitor
outlet. The quad system is shown in "Figure 4".

CARTRIDGE CHANGE DETERMINATION
Replace all Pentair Everpure SEN lter cartridges annually or when
capacity is reached or ow slows down. The cartridges on multiple
cartridge systems, including the Pentair Everpure 2SR-BW scale
inhibitor cartridge, should be changed at the same time.
If the ow has decreased it is likely that the HFUF cartridge
isdamaged.
The HFUF cartridge should be changed every three (3) years.
The system pressure gauges provide a means to read system
pressures. The left gauge will show water pressure in front of
the SEN lter cartridges. The second (right) gauge shows water
pressure after the SEN cartridges and going to the applications.
The difference between the two pressures is an indication of the
pressure drop through the SEN cartridges. A large drop in pressure
during normal operation, > 30 psig (2.07 bar), will be caused by
plugged SEN cartridges. In this case, the SEN and HFUF cartridges
should be changed.
If visible particles are on the top surface of the HFUF, these could
lead to plugging or damage to the hollow bers. Use a screen or
pleated lter to prevent these particles from entering the HFUF
pretreatment.
System Tested and Certied by NSF International against
NSF/ANSI Standards 42 and 53 for the reduction of the claims
specied on the Performance Data Sheet and at www.nsf.org.
