Owners Manual
Basic DAH Blend Center Operation
Warning:Usecarewhenhandlinghazardouschemicalsanduseprotectiveclothing/eyewearasrecommendedbyChemicalManufacturer.
The DAH “Dilution at Hand” blend center is a chemical/water solution dispensing system engineered to dilute
concentrated chemicals utilizing versatile controls and ASSE Standard 1055 Type B approved backflow
prevention devices with 1 and/or 4 GPM flow rate proportioners. Depending on the DAH blend center
equipment, the flow of inlet water and the desired mixture of chemical can be either activated by sliding a lift
button by hand, sliding the lever with the spray bottle, or depressing the trigger on the remote fill gun. Once the
valve control mechanism is activated, the water inlet valve opens allowing water to flow through the backflow
prevention device/proportioner that mixes a chemical/water solution at the desired induction rate with the use of
metering tips.
Bottle & Hose Fill Application: A return spring is used on the sliding lift button and sliding lever to prevent an
accidental overflow of chemical/water solution if unattended (Note: Unless the sliding lift button is in the
“Lock” position). To “Lock” the sliding lift button, slide the button all the way up then push it in towards the
wall. Slowly release the button and it will stay in the “Lock” position. To “Unlock” the button, the button
and/or the lever can be pushed upward to automatically release the locking mechanism.
Remote Fill Application: A return spring is used on the remote gun trigger to prevent an accidental overflow of
chemical/water solution if unattended (Note: Unless the trigger lock is in the “Lock” position). To “Lock” the
remote gun trigger, depress the trigger and slide the lock lever to the right. Slowly release the trigger and it will
stay in the “Lock” position. To “Unlock” the trigger, depress the trigger again to automatically release the
locking mechanism. Sold by DEMA Engineering Company, St. Louis, MO 63122 U.S.A.

Installing New DAH Blend Center to the Wall
1. Evaluating wall spacing for hanging
blend center on wall: Depending on
the number of individual units that are
connected together, wall space must be
closely laid out to make sure there is
adequate room. Be sure to allow a
minimum of 12 inches on both the left
and right hand sides of the blend
center. The added space will be used
for hanging the bucket fill outlet hose,
remote fill gun, and for attaching the
water supply to the blend center. This
will vary depending on the model of
the blend center. (Note: All dimensions
are shown in inches and the sketch
shows the mounting layout for a 4 unit
DAH blend center.)

I-776 Page 5of 18
Rev. G29208
2. Laying out and drilling holes in the wall for mounting the DAH Blend Center: Carefully layout the proper mounting holes on
the wall based on the information in step 1 on previous page using a tape measure and straight edge/level for hanging the blend
center on the wall. (Note: Drill two holes into the wall for each individual unit in the DAH blend center. Drill all of the holes
into the drywall using a 1/4” diameter bit for use with the included #10 x 1” long screw and anchor set. If mounting the blend
center to wood and you do not plan to use the included anchors, drill 1/8” diameter holes.)
3. Getting the water supply line and blend center ready so it can be mounted on the wall: Remove the individual unit cover(s)
by pressing down on the upper cover snap-in lever feature and pulling forward on the cover. (Note: If the blend center is equipped
with a selector valve, the phillips screw holding the selector knob will need to be removed. Save all removed components in a
safe place for re-assembly.) A water supply line must be plumbed up to the right hand side of the DAH blend center using a male
¾ - 11 ½ N.H. hose coupling fitting.
4. Mounting blend center to the wall and connecting the water supply line: Insert the anchors into drilled holes and hammer
them into the wall until they are flush with face of wall. Assemble all of the #10 x 1” long screws with a phillips screwdriver into
the anchors so the screw heads are sticking out of the wall approximately ½”. Carefully align the large section of the keyhole
slots in the blend center base(s) over the screw heads. Once positioned properly, push blend center against the wall over the
screw heads and slide it down until the keyhole slots are resting on the screws. Tighten the screws against the keyhole bosses in
each base. Connect the water supply line to the female swivel garden hose coupling on the blend center and tighten by hand.
(Note: May need to tighten hose coupling another ¼ turn with pliers but Do Not Overtighten.) Water supply pressure should be
in the 20-125 psi range and water temperature must not exceed 150 ° F. Slowly turn on the water supply and check for any leaks.
(Note: See section labeled “Trouble Shooting” on page 13 if any continual leaks are visible.) Mount water supply line to wall
with proper clamp(s) to avoid any damage to the blend center. (Go to step #5 on the next page)
Installing New DAH Blend Center/Rack Assembly to the Wall
1. Evaluating wall spacing for hanging blend center/rack assembly on wall: On the single product rack, allow a minimum of 12
inches on both the left and right hand sides of the rack. On the multiproduct rack, allow a minimum of 4 inches on both the left
and right hand sides of the rack. The added space will be used for attaching the water supply to the blend center. This will vary
depending on the model of the blend center. (Note: All dimensions are shown in inches and the sketch shows the mounting for a
single product and multiproduct rack assembly.)

by pressing down on the upper cover snap-in lever feature and pulling forward on the cover. (Note: If the blend center is equipped
with a selector valve, the phillips screw holding the selector knob will need to be removed. Save all removed components in a
safe place for re-assembly.) A water supply line must be plumbed up to the right hand side of the DAH blend center using a male
¾ - 11 ½ N.H. hose coupling fitting.
4. Mounting blend center to the wall and connecting the water supply line: Insert the anchors into drilled holes and hammer
them into the wall until they are flush with face of wall. Carefully align and position the rack over the anchors and assemble all
of the #12 x 1” long screws with a phillips screwdriver into the anchors. Tighten the screws against the rack but DO NOT
OVERTIGHTEN. Connect the water supply line to the female swivel garden hose coupling on the blend center and tighten by
hand. (Note: May need to tighten hose coupling another ¼ turn with pliers but DO NOT OVERTIGHTEN.) Water supply
pressure should be in the 20-125 psi range and water temperature must not exceed 150 ° F. Slowly turn on the water supply and
check for any leaks. (Note: See section labeled “Trouble Shooting” on page 13 if any continual leaks are visible.) Mount water
supply line to wall with proper clamp(s) to avoid any damage to the blend center. Assemble drip tray (if provided) directly below
the bottle fill units by snapping the tabs over the rod (see page 18).

Note: All induction flow rates are based on a water pressure of 40 psi.
Leaner dilutions can be achieved by ordering DEMA ultra lean metering tip kit 100-15KU.
*Metering tip color was formerly clear.
Service Note: Standard size ¼” hose barbs and metering tips that come with this model are used for water thin (1cps) products. Ratios as low as
parts-per-million can be achieved with the use of a capillary metering tip. More viscous products (75cps – 200cps) may require larger 3/8” hose
barbs and metering tips. If you are having difficulty achieving the ratio you require, call DEMA and ask for the technical department.

Maintaining and Servicing the DAH Blend Center
Caution: Turn off water supply before doing maintenance or servicing.
Warning: Use care when handling hazardous chemicals and use protective clothing/eyewear as recommended by Chemical
Manufacturer. This includes handling of chemical supply and outlet tubes.
Note: Water supply pressure should be in the 20-125 psi range and water temperature must not exceed 150°F.
Disassembling & reassembling the remote fill hose assembly:
1. Remove cover(s) and selector knob as necessary.
2. Removal of the double hose from the proportioner also involves the disconnection of both the clear and blue 1/8” I.D. tubes.
(Note: The 1/8” I.D. tubing is fairly stiff and the hose barbs can be damaged if not handled carefully.)
3. Slide the upper hose clamp on the blue high pressure tubing up above the hose barb. (Note: It is helpful to use a rotational motion
when sliding the hose clamp up.)
4. Unscrew the diaphragm nut in the direction shown on the sketch. (Note: The hose barb on the diaphragm nut will need to rotate
inside the 1/8” I.D. tubing to remove the nut.)
5. Disassemble the elbow from the front of the valve body using a phillips screwdriver. (Note: The elbow is sealed to the valve
body via an o-ring. Be careful not to loose the o-ring.)
6. Loosen the hose clamp holding the double hose to the proportioner. Remove the double hose off of the proportioner using a
steady pulling and rotational motion. Now you can get to the backflow prevention devise/proportioner.
7. Repeat the same steps above in reverse order to reassemble the remote fill hose assembly. Pay special attention to push the
double hose far enough on the proportioner so it lines up with the flat surface of the top hose barb. Also see Detail “A” for proper
installation of the o-ring onto the elbow before reassembling the elbow to the valve body. (Note: Check to see that the diaphragm
is properly seated then hand-tighten the diaphragm nut.)
8. Reassemble cover(s) and selector knob with screw if so equipped. (Do not overtighten.)

Checking backflow prevention device/proportioner, metering tip(s), and/or foot valve(s):
1. Remove cover(s) and selector knob as necessary. Remove outlet hoses and chemical supply tubes as necessary. See section
labeled “Disassembling & reassembling the remote fill hose assembly” on previous page for removing the remote fill hose
assembly.
2. Inspect metering tip(s) and foot valve(s) for build up of dried chemical. Inspect air gap proportioner for build up of hard water
mineral deposits on top nozzle or clogging of inlet screens.
3. If clogged, remove these items and soak in hot water. Hard water deposits can be removed by soaking in an off-the-shelf product
such as CLR. Clean clogged passageways with soft brush or other acceptable tools as necessary. (Note: Selector valve or elbow
needs to be disassembled from proportioner before the proportioner can be removed).
4. Replace with clean or new parts as needed.
5. Connect all outlet and chemical supply tubes. (Note: Always check and make sure the lever will slide freely and there are no
tubes rubbing the lever and resisting its movement if so equipped.)
6. Reassemble cover(s) and selector knob with screw if so equipped (do not overtighten).
Checking water valve malfunction on bottle & hose fill applications:
1. Check to see that the lever moves freely up & down. Determine which water valve is malfunctioning if equipped with more than
one valve body.
2. Follow steps 2 through 7 in the section labeled “Adding a DAH blend center to an existing DAH blend center” below for properly
removing the valve subassembly from the base(s).
3. Remove the screw and nylon washer retaining the sliding lever to the water valve body. (Note: Be careful not to let the magnet
fall out of the lever pocket and get lost as the lever is being removed from the valve body.)
4. Remove the enclosing tube nut from the valve body. (Note: Be careful when removing the nut not to lose the plunger, kickoff
spring, enclosing tube or diaphragm).
5. Check for dirt or damage impeding plunger and kickoff spring movement.
6. Inspect the diaphragm, making sure the two small pin holes (bleed holes), located in the diaphragm’s webbing membrane, are
clear to allow the valve to close. If holes are clogged, remove and soak in hot water. Carefully clean clogged passageways to
avoid any damage to the diaphragm.
7. Replace with clean or new parts as needed. Reassemble valve body subassembly per Figure 2 in the section labeled “Parts List
For DAH Blend Center” on page 14. Hand-tighten enclosing tube nut.
8. Reassemble magnet and lever to valve body with nylon washer and screw per Figure 2 in the section labeled “Parts List For DAH
Blend Center” on page 14. Do not overtighten screw.
9. Follow steps 16 through 18 in the section labeled “Adding a DAH blend center to an existing DAH blend center” on page 12 for
properly reassembling the valve subassembly to the base(s) until the blend center is completely assembled.
Adding a DAH blend center to an existing DAH blend center:
1. Evaluate wall spacing for the added DAH blend center (See step 1 in the section labeled “Installing New DAH Blend Center to
the Wall” on page 4).
2. Shut off and disconnect water supply line from blend center. If equipped with a bucket or remote fill outlet hose, carefully
remove the free end of the outlet hose hanging on the cover and set it in a safe place where it won’t get damaged.
3. Remove cover(s) and selector knob from wall mounted blend center as necessary.
4. Remove outlet and chemical supply hoses as necessary. (Note: Don’t disconnect the remote fill hose assembly.)
5. Remove lever return spring(s) located in the upper section of the individual unit(s) as shown in the upper left hand sketch in step 7
on page 11. (Note: Units with the remote fill hose/handle assembly does not have a lever or return spring.)
6. Remove the screw(s) and nylon washer(s) retaining the bottom end of the sliding lever to the base(s) as shown in the upper left
hand sketch in step 7 on page 11. You may need to remove the proportioner(s) so you can get access to the screw(s). (Note:
Selector valve or elbow needs to be disassembled from proportioner before the proportioner can be removed). (Note: Units with
the remote fill hose assembly does not utilize the lever or the screw and nylon washer.)

I-776 Page 11of 18
Rev. G29208
7. Remove the valve body mounting screws from the base(s). Carefully slide the valve subassembly from the base(s) and set it on a
clean and flat surface or table. (Note: Be careful not to separate the parts within the valve subassembly otherwise the o-rings will
need to be removed and reassembled to avoid water leakage. If the parts become separated, the o-rings will be reassembled on
step 15 on the following page.)
8. Open the new DAH blend center carton and check contents (See section labeled “Unpacking and Checking Contents” on page 4).
9. Lay out and drill holes in the wall for mounting the additional DAH blend center (See step 2 in the section labeled “Installing
New DAH Blend Center to the Wall” on page 5).
10. Remove cover(s) and selector knob from the new DAH blend center as necessary.
11. Repeat prior steps 5 through 7 in this section on the new DAH blend center.
12. Insert the anchors into the drilled holes and hammer them into the wall until they are flush with face of wall. Assemble all of the
#10 x 1” long screws into the anchors so the screw heads are sticking out of the wall approximately ½”. Install the base(s) on the
added screws. Drive the screws into the base far enough so the base can’t slide upward and off of the screw heads but loose
enough that the base can move around slightly. (Note: This will allow for base movement when installing the valve subassembly.)
13. At this time, review and determine the position in which each separate valve subassembly needs to be placed in the final valve
subassembly. (Note: Normally the bucket fill outlet hose is located in the most left position due to the convenience of hanging the
free end of the hose on the left side of the blend center cover. In the case where you have two long outlet hoses, they should be
positioned on each end of the dispenser.) Align the two valve subassemblies on the table accordingly and if necessary, valve
bodies may need to be separated from each other to properly position the valves.
14. The cap positioned on the left side of the valve subassembly and the water inlet stem assembly positioned on the right side of the
valve subassembly will be used and can remain assembled. Carefully disassemble the cap and water inlet stem assembly
positioned next to each other (center position of the two valve subassemblies). Also, remove the o-ring at each disassembled
connection. (Note: The o-ring will normally stay in the female end of the separated parts for each connection. The disassembled
cap, water inlet stem assembly, and one o-ring will not be used in the final valve subassembly.)

15. Assemble one o-ring against the shoulder of the male
boss feature for each connection needing to be
reassembled as shown in detail “A”. (Note: Lube o-
ring with water and use a twisting motion when
assembling components together for ease of
assembly.) Carefully assemble each connection by
sliding the male boss feature with the o-ring already
assembled into the female feature on the mating
component. (Note: The radial position of the cap is
important for reassembling the valve subassembly to
the bases. One groove on the cap must be facing up
and one groove down. The radial position of the
water inlet stem assembly is not critical. However,
when assembling all of these components together,
the grooves on both mating parts must align for
sliding the complete valve subassembly into the
bases. Be careful so valve bodies don’t slide apart
too far or o-ring will need to be reassembled to insure
a proper seal.)
16. Carefully align the grooves in the valve subassembly
with the mating fork features on the bases. Slide the
valve subassembly against the bases until the
mounting pads on the valve bodies rest against the
raised bosses in the bases. The lever should slide up and down freely on each individual unit when installed properly. (Note: If
unit is equipped with the lever, the lower slot in the lever must be positioned over the small raised boss in each base for the valve
subassembly to seat properly.)
17. Install the screw(s) and nylon washer(s) retaining the bottom end of the sliding
lever to the base(s) if equipped with lever. You may need to remove the
proportioner(s) so you can get access to the screw(s). (Note: Selector valve or
elbow needs to be disassembled from the proportioner before the proportioner
can be removed.) Install the valve body mounting screws into the base(s).
Tighten all of these screws including the bases to the wall but do not
overtighten. Install the lever return spring(s) in the individual unit(s). Slowly
turn on the water supply and check for any leaks. (Note: See section labeled
“Trouble Shooting” on page 13 if any continual leaks are visible.)
18. Reinstall all proportioners that were removed. Connect all outlet and chemical
supply hoses including meter tips. See section labeled “Typical DAH Blend
Center “Chemical Supply & Hose Installation” on page 6 as needed.” (Note:
Always check and make sure the lever will slide freely and there are no hoses
rubbing the lever and resisting its movement.) Reassemble cover(s) and
selector knob with screw if so equipped. (Do not overtighten.)

outlet tubing.
3. Bucket fill outlet hose is catching the bottom
edge of the sliding lever during normal usage.
1. Remove cover and visually check for sliding lever
return spring. Replace if missing.
2. Remove cover and visually check for any tubes
rubbing the sliding lever. Routing of chemical
supply and outlet tubing must not restrict the
movement of the sliding lever. Reroute tubing.
3. Don’t pull the bucket fill outlet hose too tight from
either side otherwise sliding lever may not return
properly.
Water valve is leaking. 1. Enclosing tube nut is too loose.
2. One or more of the valve o-ring connections
are out-of-position. Clearly identify each leak
prior to disassembly.
1. Shut water supply off first. Hand-tighten the
enclosing Hose nut. Do not overtighten w/tool.
2. “O-ring” seals may be pushed out of place or
missing when subassembling valve together. See
section labeled “Adding a DAH blend center to an
existing DAH blend center” on page 10-13 for
reassembling.
Threaded connections are
leaking water. 1. The connection between the blend center and water supply line is too loose or rubber washer
is missing.
2. Backflow prevention devices and/or
proportioners are too loose.
1. Shut water supply off first. Carefully tighten the
female hose coupling on the blend center to the
inlet water supply line. Do not overtighten.
2. Tighten loose connection(s) with tools if
necessary. Do not overtighten if using tools.
