High Flow Series Dual Port Manifold Water Filtration Systems
The High Flow series dual port (DP) manifold water filtration system cartridges help provide consistent high quality
water for multiple applications of cold beverages, ice, and coffee. The inlet water enters the manifolds on the left rear
side and flows through 1, 2, or 3 cartridge filters in parallel (depending upon which manifold is installed). Two separate
streams exit the manifold. One stream (on the right front side) has scale-inhibition media added from a dedicated
cartridge to reduce the ability of calcium and magnesium to precipitate as hard scale in ice machines and coffee
brewers. The other stream exits on the left side front. It supplies cold beverage dispensers and includes no scale
inhibitor. The capacity of the system is equal to the total combined flow rate and capacity ratings for the number of
cartridge filters used, regardless of the percentage of total outlet flow directed to a specific application.

Inlet and Outlet Connections
The water inlet is on the left side rear and the outlets are on both sides and are identified with labels. The fitting size is 3/4” NPT (Male). Built-in check valves (non-return) are incorporated into both outlets.
How to Use “Push-in” Connectors
CAUTION
To reduce the risk associated with property damage due to water leakage:
• Do not install unit if collet is missing. Contact your Sales Representative if collets are missing
The DP2XX & DP3XX manifolds are outfitted with a user friendly ‘Push In’ connector at the vent valve. Proper use of the
connectors is shown in the figure 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 may be a problem with the tubing and new tubing may be required.
To Attach Tubing
Push tubing straight in as far as it
will go
To Release Tubing
Tubing is secured in.
Push in collet to release tubing.
Pull tubing straight out.
How to Use the Inlet/Outlet Fitting Retention Clips
This product is outfitted with inlet/outlet fittings. The fittings can be attached or removed from the system without tools. Retention clips are semi-circular in shape with three internal tabs, bottom, center and top. Tab interlaces
with windows in the manifold head near each connection port. Clip is flexible and easily assembled following these
instruction and illustrations.
1. Insert fitting into manifold.
2. With fitting inserted into manifold port, snap clip into place beginning at the bottom window
3. Push center tab into center window.
4. Finally push top tab into top window.

• Some local codes may require the use of a licensed plumber or certified installer when disrupting a potable water line.
CAUTION
To reduce the risk associated with property damage due to water leakage:
• Any non-metallic fittings used in the installations must be of adequate rating for the line pressure.
Manifolds may be used with metal or non-metallic piping systems.
1. Shut off incoming cold water supply.
2. Select the installation location.
IMPORTANT NOTE: Allow a minimum of 3 in (7.6 cm) of space below the cartridges for change-outs.
3. Select fasteners (not included) and tools appropriate for the installation location (wall, support structure mounted to wall studs, concrete, etc.) CAUTION
To reduce the risk associated with property damage due to water leakage:
• Ensure that the location and fasteners will support the weight of the system when installed and full of water.
4. Mount the manifold/filter system to a wall using the mounting holes provided on the back plate of the metal bracket.
• It is recommended to first draw a level line on the mounting surface at the height of the fasteners. • Mark the location of the fasteners using the bracket as a template or by measuring the distance between the mounting holes.
• Install the fasteners and allow 1/4”- 3/8” (6-10 mm) of each fastener to protrude from the surface. •Install the manifold onto the fasteners.
•Tighten the fasteners.
5. Install inlet (left rear) and outlet fittings (right front to ice/coffee and left front to beverage) to the manifold. All connections terminate with a 3/4” NPT (male) fitting. The inlet kit includes a fitting and a ball valve. The left front outlet is a fitting only. The kit for the right side outlet to ice includes the fitting, a stainless-steel filter head, two (2) nipples and a check valve. The instructions for the installation clips are on page 5 (PTFE tape is not included).
IMPORTANT NOTES: Be sure to install the stainless steel fitting head with the flow arrow. 6.Remove the sanitary caps from the water filter cartridges, and apply a light coat of water or water-grade lubricant to the o-rings on each of the cartridges.
7.Align the tabs of the cartridge with the slots in the retaining plate and insert the cartridge into the manifold. 8.Turn the cartridge to the right until a clicking sound is heard. Repeat for the remaining cartridges; the clicking sound indicates the cartridge is properly engaged.

Cartridge Change-out Procedure
CAUTION
To reduce the risk associated with property damage due to water leakage:
• Read and follow Use Instructions before installation and use of this system.
• The disposable filter cartridge MUST be replaced every 12 months, at the rated capacity or if a noticeable
reduction in flow rate occurs.
The water filter cartridges will need to be changed every 6-12 months, at the rated capacity, or when low
pressure in indicated on the manifolds pressure gauge, whichever occurs first. Depending on local water
quality, you may need to change the cartridges prior to the recommended change-out. The loss of flow to
carbonators or improper fill at the ice maker are also indicators that the cartridges will need to be replaced
1. Shut off the inlet water by rotating inlet ball valve 1/4 turn to the left (clockwise) on manifold to the “OFF” position.
2. Depressurize system. Use plastic tubing and vent valve for DP2XX and DP3XX manifolds. There is no vent valve on DP1XX manifold.
3. Push tab to release cartridge locking mechanism while simultaneously rotating cartridge slightly to the left.
WARNING
To reduce the risk associated with back strain:
• Follow safe lifting procedures.
4. Using both hands and holding cartridge from the bottom, rotate the cartridge a quarter turn to the left and gently pull down.
IMPORTANT NOTE: A small amount of water will drain from manifold as cartridge is removed.
5. Remove the sanitary caps from the water filter cartridges, and apply a light coat of water or water-grade lubricant to the o-rings on each of the cartridges. Align the tabs of the cartridge with the slots in the
retaining plate and insert the cartridge into the manifold. Turn the cartridge to the right until a clicking
sound is heard. Repeat for the remaining cartridges; the clicking sound indicates the cartridge is properly
engaged.
6. Slowly turn the inlet water ball valve on the manifold to the left (counterclockwise) to the ON position, and check for leaks.
7. Install the smaller scale inhibitor cartridge by engaging the threads in the stainless steel tee and rotating to the right (clockwise) until snug, regardless of final label orientation. 8. Flush system in accordance with performance data sheet supplied with the water filtration cartridges.
