Pentair Everpure SR-X Installation Manual

Installation and Operation Guide

INTRODUCTION

The Everpure SR-X Scale Reduction Feeders are designed to efﬁciently dispense scale inhibiting products into foodservice water ﬁltration systems. There are two versions. One (SR-X) is intended for cold water applications such as ice machines and replaces the previous Everpure IMF Feeder. The other (SR-X w/Deliming Kit) is intended for hot water applications such as steamers and replaces the previous Everpure AR-X Feeder.

THE SR-X FEEDER (EV9798-45) INCLUDES:

• A clear bowl plastic housing

• An opaque head with integral mounting bracket

• An Everpure SS-IMF ScaleStick cartridge containing HydroBlend, a unique, specially blended compound that inhibits mineral scale deposits and provides corrosion protection for water-fed equipment.

• Two SS-IMF Spacers (adapts SS-IMF to 10” bowl)

• A sump wrench

THE SR-X FEEDER W/DELIMING KIT (EV9797-20) INCLUDES:

• The same housing and head included in the SR-X Feeder.

• An Everpure SS-10 ScaleStick cartridge containing the HydroBlend compound.

• A check valve with pipe nipple (packed loose) to prevent backﬂow in hot water applications.

• One 2.2 lb. packet of Everpure ScaleKleen scale remover

• A dip-tube to convert the SR-X Feeder for use in introducing the ScaleKleen product.

• A sump wrench

NOTE: The SR-X and SR-X w/Deliming Kit Feeders are supplied with different versions of

ScaleStick cartridges. The SR-X Feeder includes the SS-IMF ScaleStick EV9799-32 which is shorter (approx. 7” in height) and contains less of the HydroBlend material than the SS-10 ScaleStick EV9799-02 (approx. 10” in height) included with the SR-X Feeder w/Deliming Kit. The SS-IMF cartridge requires two 2-1/4” spacer (included with EV9798-

45) which adapts it for use in the new, longer SR-X bowls.

SR-X SCALE REDUCTION FEEDER INSTALLATION

SR-X Feeders are provided in three forms:

1. As stand-alone feeders where their functions may be added to existing water consuming

foodservice equipment installations.

2. As integral elements of standard Everpure water ﬁlter systems.

3. As add-on elements to standard Everpure water ﬁlter systems. The SR-X Feeders

incorporate provisions for retroﬁtting onto new style Everpure multi-cartridge/multifunction ﬁlter systems to provide scale control as needed. Adaptation is accomplished by adding an optional post-feeder bracket to an existing system. Detailed installation instructions come with the post-feeder brackets.

Before starting the installation, be sure to shut off both power and water to the equipment being served. For servicing convenience, a manual shut-off valve should be installed in the water line ahead of the feeder.

IMPORTANT: Always use a NSF approved pipe dope or Teﬂon tape at all thread connections.

CONNECT TO INLET/FEED WATER MAKE-UP LINES ONLY. DO NOT CONNECT TO ICE MACHINE CONDENSER OR STEAMER CONDENSATE COOLING LINES

1. Select a suitable location for mounting the SR-X Feeder and install mounting screws 2

apart. If installing the EV9797-20 SR-X Feeder w/Deliming Kit, assemble the 3/4” check valve and pipe nipple (provided loose) onto the outlet of the feeder head.

2. Un-thread the head assembly from the bowl.

3. Locate the ScaleStick cartridge in the carton and remove its shrink-wrapping.

7” length), locate the two SS-IMF Spacers in the bowl. This is a short length (approx. 21⁄4”) of ScaleStick cartridge bottom used to extend the length of the SS-IMF cartridge so that it ﬁts securely into the 10” SR-X bowl. Insert the spacer into the bottom of the SS-IMF cartridge and proceed to the next step.

5. Insert the ScaleStick (black O-band seal at the top) onto the outlet stub on the bottom of the feeder head .

6. Check to be sure the o-ring on the bowl is clean and sufﬁciently lubricated and apply a high quality food grade silicone lubricant if more is needed.

7. Thread the bowl onto the feeder head with ScaleStick by hand while aligning the ScaleStick with the guide seat in the bottom of the bowl. Snug the bowl with the sump wrench (EV3112-41).

8. Connect the inlet water line to the inlet ﬁtting connection on the SR-X Feeder head. Connect the SR-X outlet to the piping/tubing leading to the equipment being treated.

9. Continue with installation of the rest of the ﬁlter system, if the SR-X Feeder is being added on.

10. Turn on water to the SR-X Feeder and momentarily depress the red button on the head to purge air from the unit.

CARTRIDGE CHANGE INSTRUCTIONS

1. The SR-X Feeder bowls and ScaleStick cartridges are transparent, permitting continuous monitoring of product level. When the product level in the ScaleStick cartridge drops to within 1/2” from the bottom, the cartridge should be replaced.

2. Turn off inlet water to the feeder and momentarily depress the red button on the head to relieve pressure.

3. Un-thread the bowl from the head, empty water from the bowl and remove the used cartridge.

4. IMPORTANT! If changing cartridges in an SR-X Feeder using the SS-IMF ScaleStick cartridge (approx. 7” length), remove the SS-IMF Spacer from the bottom of the used cartridge and set it aside. Do not discard the spacer. Proceed to the next step.

5. Clean the bowl with a mild solution of unscented dishwashing detergent. DO NOT use soap, strong or scented detergents, chemical solvents or abrasives.

6. Remove the shrink-wrapping from the new ScaleStick cartridge.

7. IMPORTANT! If replacing an SS-IMF ScaleStick cartridge into an SR-X Feeder, reuse the SS-IMF Spacer set aside from Step 4. Insert the spacer into the bottom of the new SS-IMF cartridge and proceed to the next step.

Note: If the SS-IMF Spacer is missing or misplaced, a replacement spacer may be ordered. Alternatively, you may cut the bottom 2-1/4” from the used ScaleStick and use that portion as the spacer.

8. Insert the cartridge (black O-band seal at the top) onto the outlet stub on the bottom of the feeder head.

9. Check to be sure the O-ring on the bowl is clean and sufﬁciently lubricated and apply a high quality food grade silicone lubricant if more is needed.

10. Thread the bowl onto the feeder head with ScaleStick by hand while aligning the ScaleStick with the guide seat in the bottom of the bowl. Snug the bowl with the sump wrench (EV3112-41).

11. Turn on water to the SR-X Feeder and momentarily depress the red button on the head to purge air from the unit.
