DAH "Dilution at Hand" Blend Centers
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: 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.
