START UP PROCEDURES

SLOWLY turn on main water pressure until water ows between 5 & 12 gpm (11-45 lpm) or 30 psi (2 bar) maximum to fully prime the suction hose.

SLOWLY open the water supply valve and all valves downstream of injector to release entrapped air. Carefully open inlet valve allowing water to enter and pressurize the injector. Open outlet valve

and close bypass valve. Water will now ow through the injector, and a continuous sound will be emitted from the injector as water passes through it. Check for system leaks (see page 5) and correct

if necessary. Adjust the outlet valves downstream from the injector, if necessary.

QUICK TIPS:

To maintain a long service life for your MiniDos injector

1. Always cover solution container and keep it clean

2. Always use clean water

3. Always lter inlet water

4. Always keep solution lter (#27) 2” from bottom of container

5. Always stock main wear parts for lower end

Trouble-shooting your Dosmatic injector

Injectors should make a gentle clicking noise when in operation

If the unit is not clicking, contact your authorized Dosmatic repair distributor or return the unit to Dosmatic USA, Inc

If the unit is clicking, but not pulling solution, please inspect the lower end of the injector (see lower end diagrams) as follows:

Exterior Inspection

1. Inspect and clean lter (#27)

2. Inspect the suction tube (#25) for cracks. Replace suction tube if holes exist

3. If injector still does not pull solution, please proceed to steps 4-7

Cleaning the suction tube tting

4. Remove pin #79 and carefully pull out the inner cylinder (#37)

5. Unscrew the suction tube tting (#11) from the inner cylinder (#37)

6. Clean and rinse suction tube tting assembly (#11). Replace any damaged parts

7. If injector still does not pull solution, please proceed to steps 8-12

How to replace wear parts

8. Unscrew the external cylinder (#7), separating it from the body of the injector

9. Take hold of the shaft (#51) and turn it 90 degrees in any direction to release it.

Pull shaft from its housing

10. If you have the 0.4%, remove the dosage piston (#44) by unscrewing dosage piston support (#52) from lower shaft assy (#51). NOTE: Due to the delicate nature of the 0.4%, extra care should be taken to monitor dosage levels, verify

solution is free of debris, and to perform wear maintenance regularly.

If you have the 1% or 2.5%, remove the dosage piston (#44) by turning the lower shaft (#51) one quarter

turn and pull down.

If you have the 5% or 10%, remove the dosage piston (#44) by depressing the two “ears” of the shaft (#52) simultaneously and removing the piston upwards. Replace dosage piston by sliding a new #44 from

top to bottom of the shaft until you hear a click.

If you have the 20%, remove the dosage piston (#44) by unscrewing the capscrew (#93) and remove the dosage piston (#44) by pulling down. Clean and inspect O-ring (#14). The translucent openings (larger diameter/thinner lips) of the dosage piston should be on top.

11. Clean, dry and inspect inside the inner cylinder (#37 or #7 if 20%) from scratches or cracks. If damaged,

replace inner cylinder.

INTRODUCTION:

Please take the time to read this instruction manual thoroughly and follow the procedures. This will help increase the life of your injector.

Certain precautions, which are marked with this symbol need to be read carefully...

The injector is packaged with the following items: (shown in gure 1)

Dosmatic Injector (not shown)

Dosage Piston O-ring

Manual (not shown)

SAFETY:

1.SELECT A LOCATION: that is on the water line that chemical injection is desired and meets all

the following requirements as well as all applicable local codes.

Remove Red Caps Prior to Installation.

NOTE: The entire water line down stream from the injector will have chemical injected into it. If

the chemical injected makes the water unsafe to drink, label the water lines.

WARNING NOT FOR HUMAN CONSUMPTION!

2. AN APPROVED BACK FLOW PREVENTOR MUST BE INSTALLED, in the water

line ahead of the unit to prevent water and chemical mixture from entering the source water supply.

3. AVOID A POTENTIALLY HAZARDOUS CHEMICAL ACCIDENT: An injector loca-

tion should be selected to provide a safe, but accessible, place for the chemical solution container. It

should be kept away from children and/or high usage areas.

4. AVOID SOLUTION CONTAMINATION, use only clean FILTERED water. Do not allow

contaminants to enter the solution container because they will be pumped into the water line, and can cause the spread of disease and can also cause excessive wear.

5. WATER TEMPERATURE Max: 100°F or 38°C Min: 32°F or 0°C

6. MAX WATER PRESSURE 10% & 20% - 65 PSI/4,5 BAR

0.4% - 5% - 140 PSI/9,7 BAR

7. RELEASE WATER PRESSURE, before working on injector

English:5

INSTALLATION:

1.NOTE: Water going through injector must be free of sand, dirt and grit. Installation of 140 mesh

(104 micron) or ner lter will be required.

2. MOUNT INJECTOR: Securely to a solid object such as a wall. Note arrow on injector indicat-

ing water ow. See g. 4.

3. BACKFLOW PREVENTOR: Install one adequately sized that meets your local code require- ments.

4. BYPASS VALVE: To bypass injector when not in service or to service injector pipe in the three valve bypass arrangement as shown in Fig. 3

5. CHECK SYSTEM FOR LEAKS: Open the bypass valve (A), close valves (B) and (C) so that the water will not ow into injector SLOWLY turn on the main water line so that water will

run through the plumbing system. Turn on all of the valves located downstream from your injector

to release trapped air. Slowly turn on the inlet valve (B). Open the outlet valve (C) at injector outlet. Close (A). As water travels freely through your injector, you will hear a soft “clicking” sound.

6. SOLUTION CONTAINER: Refer to gure 5. You may use any size container but we recom- mend using one with a lid or cover. To connect your solution container gently push the end of the

suction tube (#25) onto the bottom of the tting assembly (#11). Place the lter into the solution container at least 2 inches (5cm) from the bottom. Cover the solution lter with at least 2 inches. (5cm) of chemical solution.

SERVICE FLOW: Water drawn down stream from the injector will automatically cause the injec-

tor to “click” and inject the set amount of solution into the water line. The higher the ow rate the more frequent the clicking, as the injector is designed to inject solution at the same set ratio regardless of water ow.

Water ow and pressure must be within the established specications. See the specication section

on page 10 for your model.

CHANGE FEED RATE: The feed rate on the injector is adjustable EVEN WHILE OPERATING

AND UNDER PRESSURE. Rotate the “Ratio Adjustment Sleeve” (#61) Important: for the 20% model rotate the #7 Ratio Adjuster, to change the solution injection ratio. See g. 5,. The setting

indicator mark indicates the approximate ratio of injection setting. Check outlet water for chemical

to assure desired feed rate is being delivered.

NOTE: Do not rotate Ratio Adjuster below lowest setting line on decal. This can cause the injector to lock.

BYPASS OPERATION: Injecting solution into the water line can be TEMPORARILY stopped

with the optional on/off feature. Moving the “On/off Lever” to the “OFF” position allows service water to pass through the injector without injecting chemical. With the on/off lever set to the “ON” position the injector will operate as normal and “clicking” will be heard when water is owing. It

is recommended to use the three valve bypass in Fig. 3, for continued bypassing or servicing of the injector.

MAINTENANCE:

RINSE INJECTOR AFTER EACH USE, additive allowed to remain in injector can dry out and damage lower end at the next start up. Put suction tube into a 1 qt. (4 liters) or more con-

tainer of fresh ltered water. Pull fresh water through the injector by operating until container is

empty. This procedure is not needed for continuous operation.

BYPASS INJECTOR: When not in use put the injector in bypass mode by using the three valve

bypass (preferred) or the optional on/off lever on the injector.

CLEAN SUCTION TUBE FILTER SCREEN: Inspect each time new solution is added. Clean

as frequently as necessary by washing in fresh water. Remove lter screen (#27) from suction tube (#25) and run water backwards through it. Replace if necessary. Keep lter screen off bottom of

solution container to prevent dirt and precipitate from contaminating solution.

STORAGE: For extended storage, rinse injector as described above and place entire injector

underwater (in 5 gal container). Monthly, apply a small amount (thimble full) of chlorine bleach to

avoid algae growth.

CLEAN SOLUTION CONTAINER: Keep covered to prevent any contaminants from entering

container. Rinse container thoroughly and often. Do not mix chemicals together that might react and cause a precipitate. Use FILTERED WATER when lling container.

CLEAN INLET FILTER: Clean or replace inlet lter as required to increase the life of the unit

as well as reduce pressure loss.

REPLACE DOSAGE PISTON AND SHAFT SEAL: The injector is shipped with a spare Dos-

age Piston (44) and shaft seal (17), see Fig. 1, as these are normal wear parts, replace both when

solution injection is less than set amount.

English:10

TROUBLE SHOOTING:

NO CLICKING SOUND

1. Water ow rate exceeds rated service ow of injector: Reduce ow rate (See Specications Pg. 10).

2. Operating pressure exceeds maximum limit: Install a pressure reducer valve (See Specica- tions Pg. 10).

3. #17 o-ring if leaking: Replace.

4. Main piston assembly #9 worn: Replace #9 and install a 104 micron lter before injector to

remove abrasive particles from water.

5. Cover #1 or main body #40 bores worn or scored: Lightly sand inside diameter of bores to

remove scoring grooves. Install a 104 micron lter to remove abrasive particles from water.

6. Poppets (Upper or Lower) are off poppet arms:

ow and/or pressure.

CLICKING SOUND WITHOUT SUCTION OF SOLUTION

1. Dosage piston #44 and o-ring retainer #15 are installed incorrectly: Be sure #44 dosage

piston is installed thin lips up.

2. Dosage piston #44 worn: Replace as necessary.

3. O-ring seat #14 or dosage piston #44 damaged: Replace as necessary.

4. #7 cylinder is worn or scored: Replace

5. #17 o-ring is worn and/or loose: Replace

6. Suction tube #25 or suction tube tting #11 cracked & leaking: Replace as necessary

7. Clogged suction tube lter: Replace and/or clean as necessary.

Replace all poppet assemblies and reduce

8. Check valve #13 leaking: Clean & replace as necessary.

WATER RE-FILLING SOLUTION TANK

1. Check valve #13 leaking: Check seat area on suction tube tting #11. Check valve and seal

must t loose in the suction tube tting.

2. Washer seal on #13 is swollen: Replace with new check valve assembly.

The Dosmatic Warranty

We believe that we make the best and most reliable water-driven injectors available. Therefore, our war-

ranty reects our condence. We will back our units with the best guarantee available.

Dosmatic will provide for replacement of all parts proven to be defective in material or workmanship from the date of purchase for the following time periods:

3 years - The cover and body are warranted to be free from defects in materials and workmanship for THREE YEARS from date of purchase, or we’ll replace them free of charge. 2 years - The water motor is warranted to be free from defects in materials and workmanship for TWO YEARS from date of purchase, or we’ll replace it free of charge. 1 year - The lower end (chemical pump) is guaranteed for ONE YEAR, or we’ll replace it free of charge.

Return the unit to the distributor or to Dosmatic’s manufacturing facility, freight prepaid. Upon inspection, the unit will be repaired or replaced at Dosmatic’s option free of charge, if found to be defective in material

or workmanship and will be returned freight prepaid.

Possible warranty issues may arise if injector body is disassembled. If you suspect you are having a problem in the motor piston assembly or inside the body please contact

Dosmatic or any accredited warranty station to arrange to send the injector in to be evaluated and/or repaired. Before using any aggressive chemicals, please visit www.dosmatic.com to conrm chemical com-
