Nu-Plus CFS™ Filtration Systems Installation instructions

INTRODUCTION

The Nu-Plus CFS water ﬁltration systems come in the following head conﬁgurations:

•Single Head with pressure gauge 4623-01.

•Twin Head in parallel (equal water ﬂow through cartridges) and pressure gauge 4623-02.

•Twin Head in series ﬂow (ﬂow through one cartridge, then the other) with pressure gauge 4623-06.

•Triple Head in parallel ﬂow with pressure gauge 4623-03.

Filter capabilities consist of the reduction of sediment particulate as well as chlorine and other objectionable taste

and odors of the water which would adversely affect the taste of carbonated and non-carbonated beverages,

coffee and ice. Also, a food-grade scale and corrosion inhibitor can be automatically fed into the water to

inhibit the formation of scale in ice machines and coffee makers. Nu-Plus CFS ﬁlters have been tested by the

manufacturer against ANSI/NSF Standard 53 for the reduction of chlorine taste and odor.

SAFETY

Always follow these safety precautions when installing and operating Nu-Plus CFS water ﬁltration system:

•DO NOT use with water that is microbiologically unsafe or of unknown quality without adequate disinfection

before or after the system.

•DO NOT use a torch or other high temperature source near ﬁlter or cartridge system.

•DO NOT install on lines with pressures above 100 psi (690 kPa). The system should be protected from water

hammer.

•DO NOT install in direct sunlight or outdoors.

•DO NOT reverse connections. The system must be installed with the inlet and outlet as labeled.

•DO NOT install ﬁlter system in locations where it can be damaged by other freestanding equipment.

•Protect from freezing.

INSTALLATION must comply with existing state or local plumbing codes.

GENERAL GUIDELINES

Caution: Read instructions completely before attempting to install the ﬁltration system.

The Nu-Plus CFS water ﬁltration systems should be located on the incoming cold water line and preferably

away from heavy trafﬁc areas. The system should be mounted on a wall, support structure or the back of the

equipment. In addition the following should be observed:

•Allow a minimum of 2˝ (5 cm) clearance space under the ﬁlter system to facilitate cartridge change-out.

•This product is designed for cold water use only (less than 100˚F/38˚C). Passing hot water through this product

may seriously damage ﬁlter housing and/or cartridges.

•Nu-Plus CFS products may be used with metal or non-metallic piping systems.

•Any non-metallic ﬁttings used in the installation must be of adequate rating for the line pressure.

•Nu-Plus CFS heads come with 3/8 ˝ Quick Connect ﬁttings.

•Nu-Calgon recommends regularly scheduled maintenance and the replacement of the ﬁlter cartridge(s) in order

for the product to perform as designed. The ﬁlter cartridge may need to be replaced every 6 months depending

upon the application, local water conditions, and how the technology was applied. Nu-Calgon shall not be liable

for system failures due to improper application or maintenance.

HEAD AND CARTRIDGE INSTALLATION INSTRUCTIONS

1. Shut off incoming cold water line.

2. Mount ﬁlter system to a wall or support structure using mounting bracket provided.

3. The installation of a shut-off on the water line before the ﬁlter head is recommended.

4. The ﬁlter head is equipped with 3/8 ˝ female connectors designed to receive 3/8 ˝ copper or plastic tubing. First

apply a light coat of food-grade lubricant (provided) to the tubing. Then, simply insert the tube into the female

connector until it seats. At that point it will have gone past the internal O-Ring that provides a watertight seal.

Repeat for both inlet and outlet connections. If desired, install the enclosed ﬂush value into the outlet ﬁtting ﬁrst,

and then install the outlet water line into the outlet of the ﬂush valve.

5. Locate ﬁlter cartridge and remove plastic shrink wrap. Remove the black cap from the top of the ﬁlter covering

the ﬁlter’s O-Ring’s.

6. Apply a light coat of food-grade lubricant to the O-Rings on the Nu-Plus CFS cartridge(s).

7. Prepare to insert cartridge(s) into ﬁlter head by holding cartridge with the label facing to the left. Insert cartridge

and turn toward the right until a clicking sound is heard. Note: The clicking sound indicates that the cartridge is

properly engaged, and label should be visible.

8. For twin or triple head installations repeat steps 5, 6, and 7 for each cartridge.

EQUIPMENT START-UP PROCEDURE

1. When using included ﬂush valve, make sure ball valve is in closed position. Lube tubing with food grade

lubricant, insert the tubing on the outlet side of the system until it seats.

2. Turn on incoming water to system.

3. Check for leaks.

4. Open ﬂush valve if installed and run water through system for 5 minutes to a bucket or drain to remove

entrapped air and carbon ﬁnes.

5. Close ﬂush valve.

6. The system is now ready to operate.

CARTRIDGE CHANGE OUT INDICATORS

Pre-ﬁlter cartridges will need to be changed when:

•Low pressure is sensed. Check gauge for pressure below 20 psi (138 kPa).

The loss of ﬂow to carbonators or improper ﬁll at the ice machine or coffee maker is also an indicator that

cartridges need to be replaced.

CARTRIDGE CHANGE OUT PROCEDURE

It is recommended that cartridges with scale inhibitor 4623-11 (SS) and 4623-13 (STOP) be replaced every 6

months. The 4623-10 (S) and 4623-12 (TOP) cartridges should be replaced when pressure drops below 20 psi,

unpleasant taste/odors are noticed, or every 12 months whichever occurs ﬁrst.

1. Shut-off inlet water to the system.

2. Depressurize system by opening the ﬂush valve.

3. Lift red knob on the top of the head upward and hold.

4. With other hand, hold the cartridge securely and turn the cartridge to the left.

5. Gently pull cartridge straight down and discard.

6. Apply a light coat of food-grade lubricant to O-Rings on the Nu-Plus CFS cartridge(s).

7. Insert the cartridge into ﬁlter head by holding cartridge with the label facing to the left. Turn toward the right

until a clicking sound is heard. Note: The clicking sound indicates that the cartridge is properly engaged.

Repeat steps 3-7 for remaining Nu-Plus CFS cartridges.

8. Direct tubing on ﬂush valve to drain or bucket to capture water.

9. Turn on the inlet water to the system.

10. Flush system for 5 minutes to remove entrapped air and carbon ﬁnes.

TROUBLESHOOTING GUIDE

Problem Possible Issue Solution

No water is available from

the ﬁlter system

Check incoming water to

the ﬁlter system

If water is not ﬂowing to the ﬁlter system, locate and correct

restriction point.

Check to see if inlet valve

is open

If closed, turn the lever so that the water line is open.

Check to see if water is

passing through the ﬁlter

Turn off water to the ﬁlter system and disconnect the tubing from

the equipment being serviced. Place tubing that is connected

to the outlet side of the ﬁlter system into a drain or bucket. While

holding the tubing secure, turn water on slowly to check to

see if water is passing through the ﬁlter system. If water is not

passing through the system, the cartridge needs to be changed.

See installation instruction to change the ﬁlter or ﬁlters. See

CARTRIDGE CHANGE OUT INSTRUCTIONS to change the

cartridge(s).

Water delivery is slow

from the ﬁlter system to

the equipment. Slow ﬁll to

ice machines, short brew

at coffee machine, not

enough water to post mix.

Check incoming water to

the ﬁlter system

Check to see if the inlet

water line valve is not

opened all the way

If the water pressure is low or the ﬂow to the ﬁlter is slow, locate

and correct the restriction point.

If not adequately opened or partially closed open valve.

Check to see if the ﬁlter is

clogged

Turn off the incoming water on the inlet side of the ﬁlter system

and disconnect the tubing on the outlet side of the ﬁlter system.

Place tubing that is connected to the outlet side in a drain or

bucket. While holding the tubing secure, turn the valve slowly to

check to see if water is passing through the system. If water is not

passing through the system, the cartridge needs to be changed.

See CARTRIDGE CHANGE OUT INSTRUCTIONS to change the

cartridge(s).

Water leaks out between

the ﬁlter and the ﬁlter head

Check to see if the ﬁlter is

turned completely to the

right as far as it will go

Turn off the water at the inlet side of the ﬁlter system. Turn the ﬁlter

to the right by griping it with both hands and turning.

Check to see if the o-ring

needs to be lubricated

Turn the water valve off on the inlet side of the ﬁlter system. Turn

the cartridge to the left to remove. If the O-Rings are dry, add a thin

layer of lubricant to the O-Ring and re-install as explained in the

installation instructions.

Short Filter Life Temporary dirty water Install or change pre-ﬁlter cartridge.
