Basic DAH Blend Center Operation

Warning: Use care when handling hazardous chemicals and use protective clothing/eyewear as recommended by Chemical Manufacturer.

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: 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.

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. (No te: 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 v alv e bod y. (N ote: 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.)

I-776 Page 9 of 18 Rev Q-36858 5/5/11

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 t he 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 webb ing membran e, 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 10 of 18 Rev Q-36858 5/5/11

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

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 blen d 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 pos ition due to the conv enience 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.)

I-776 Page 11 of 18 Rev Q-36858 5/5/11

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 oring 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

“Air Gap” Proportioner is dripping or spraying a mist (fan pattern) of water.

Sliding Lift Button won’t “Lock” open for continuous flow of chemical/water solution.

Water valve is not shutting off completely.

Water valve is leaking. 1. Enclosing tube nut is too loose.

Threaded connections are leaking water.

Proportioner continues to draw chemical after water valve is closed.

Can’t pull the Remote Fill Hose Assembly off of the proportioner.

Trigger on Remote Fill Gun is very hard to squeeze.

* (See section labeled “Checking backflow prevention device/proportioner, metering tip(s), and/or foot valve(s)” on page 10 for more information.)

1. Insufficient water supply pressure.

2. Inspect foot valve for dried chemical or dirt.

3. Proportioner metering tip clogged with dried

chemical.

4. Inspect Air Gap proportioner for mineral

deposit build up on top nozzle or inlet screen.

1. Inspect “Air Gap” proportioner for mineral

deposit build up on top nozzle or inlet screen.

1. “Sliding lift button” return spring may be

missing. (Note: Lift button must be slid up before it will push in.)

2. Not using the proper procedure for locking the

water valve open.

1. “Sliding lever” return spring may be missing.

2. “Sliding lever” is not returning all the way

down due to interference between the sliding lever and either the chemical supply and/or outlet tubing.

3. Bucket fill outlet hose is catching the bottom

edge of the sliding lever during normal usage.

2. One or more of the valve o-ring connections

are out-of-position. Clearly identify each leak prior to disassembly.

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. Concentrated chemical is positioned higher

than the proportioner.

1. Hose Clamp is not loose enough.

2. Both 1/8” I.D. tubes must be removed prior

to removing the double hose.

1. High pressure and low pressure (blue and

clear) hoses are crossed.

1. 20 PSI is the minimum allowable pressure. Seek

Plumber if necessary to increase water pressure.

2. * Soak in hot water to clean.

3. * Soak in hot water to clean interior passages.

4. * Soak nozzle and inlet screen in hot water or off

the shelf product such as CLR to clean and remove mineral deposits.
