NOTICE Indicates hazardous situation which, if not avoided, may result in property damage.

WARNING

Read entire manual. Failure to follow all guide and rules could cause personal injury or property damage.

• Check with your local public works department for plumbing codes. You must follow their guidelines as you install the water ltration system.

• Your water ltration system will withstand up to 125 pounds per square inch (psi) water pressure.

To reduce the risk associated with choking:

• DO NOT allow children under 3 years of age to have access to small parts during the installation of this product.

To reduce the risk of serious injury associated with the potential ingestion of chemicals or contaminants:

• Do not use with water that is microbiologically unsafe or of unknown quality without adequate disinfection before or after the system.

• Flush RO Cartridge: Before use, you must ush the RO cartridge as specied in the installation instructions, and discard any water generated until ush is
complete. Failure to do so could cause serious injury from exposure to chemicals that can be extracted from the RO membrane during this initial ush.

• Sanitize and Flush Tank: Before use, you must sanitize and ush the hold tank as specied in the installation instructions. Sanitizing the hold tank minimizes
the risk for exposure to contaminants. Failure to ush the hold with water after sanitizing could cause serious injury from exposure to sanitizer present.

NOTICE

To reduce the risk associated with property damage due to water leakage or ooding:

• Read and follow Use Instructions provided with the original system prior to use of this replacement cartridge.

• The pre-lter and post-lter cartridges MUST be changed every 12 months, or sooner if the rated capacity is achieved or a noticeable reduction in ow
occurs.

• The RO membrane cartridge MUST be changed every 24 months, or sooner if a noticeable reduction in ow occurs.

• Failure to replace the lters and RO membrane cartridges at recommended intervals may lead to reduced lter performance and failure, causing property
damage from water leakage or ooding.

• Protect from freezing, remove all cartridges when temperatures are expected to drop below 40°F (4.4°C).

• DO NOT install systems in areas where ambient temperatures may go above 100°F (37.8°C).

• DO NOT install on hot water supply lines. The maximum operating water temperature of this lter system is 100°F (37.8°C).

• DO NOT install if water pressure exceeds 125 psi (862 kPa). Contact a plumbing professional if you are uncertain how to check your water pressure.

IMPORTANT NOTE:

The RO membrane cartridges have green labels and will only t into the head on the right side of the manifold (head has a green 3M label).

Shut Off Procedure:

RO membrane cartridge MUST be changed every 24 months or sooner. The pre-lter and post lter cartridges MUST be changed every 12 months or sooner.

1. Unplug system from the electrical outlet, which will shutoff feedwater to RO unit.

2. Conrm the operating pressure gauge (left) decreases to 0 psi. Note: Tank pressure gauge (right) will not decrease from the observed pressure.

kPa, 4.14 bar) (right gauge). Tank operating pressure for the 220-240VAC is ON at 50 psi (345 kPa,

3.45 bar) and OFF at 70 psi (483 kPa, 4.83 bar).

9. Flush membrane by opening tank line sample valve and empty storage tank to drain. Operate the
system for at least 24 hours to ush the RO membrane. Discharge all water generated during the
ushing procedure to drain. Close the tank line sample valve after ushing is complete.

10. Sanitize the storage tank and RO system according to the storage tank and RO system
sanitizing instructions on page 3.

Blending Valve Adjustment Instructions:

IMPORTANT NOTES:

• Typical TDS (Total Dissolved Solids) values for coffee are 80-200 ppm (parts per million) and occasionally lower for espresso, depending
upon taste preference. Typical TDS valves for steam and combi ovens are less than 50ppm.

• The blending valve should be set at start-up and checked periodically. This valve is a precision metering valve that has a lock nut.

• To set blending valve use TDS monitor set in the "out" position.

1. Open the blend line shut off valve.

2. Allow the unit to run for 2 minutes.

3. To adjust blending, rotate the blending valve to the left (counterclockwise) to increase the product water TDS and to the right (clockwise) to decrease the
product water TDS (See Figure 2 item #2 below). The blending valve should be opened intermittently a quarter turn at a time. Check the TDS after each
incremental adjustment and again two (2) minutes after the desired TDS value is reached. Re-adjust and check, as needed. (See Figure 2-item #2 below)

4. Lock the blending valve using the lock nut.

5. After product water TDS is set, it should be checked periodically during operation to conrm it is at the desired level.

IMPORTANT NOTE: The TDS Monitor is push-button operated and requires two (2) 357A batteries. (Included in TDS meter)

To Attach Tubing

To Release Tubing

Push tubing straight in as far as it
will go

Tubing is secured in. Push in collet to release tubing. Pull tubing straight out.

Figure 4 (How to Use “Push-in” Connectors)

This product is outtted with a user friendly ‘Push In’ connector at the vent valve. Proper use of the connectors is shown in the gure below. It is most
important that the tubing selected for use with these connectors be of high quality, exact size and roundness, and with no surface nicks or scratches.
If it is necessary to cut the tubing, use a plastic tubing cutter or sharp razor knife. Make a clean square cut. Should a leak occur at a “Push-In”
connector, the cause is usually a problem with the tubing.

To Fix:

1. Relieve pressure 2. Release tubing 3. Cut off at least 1/4” from end

4. Reattach tubing 5. Conrm connection is leak free
