2. INSTALLATION

indicating tee is to be installed w ith e x isting faucets according to local plumbing codes in the state o f Wisco nsi n and any other state tha t requires the use of a pressure indicat ing tee. WARNING: Water supply should not exceed 125 psi and water temperature must not exceed 150°F. A. MOUNTING AND WATER SUPPLY:

Use mounting template enclosed to locate the mounting screw positions. Drill all of the holes into the dry w all usi ng a 1/4” di ame ter bit for use with the included # 1 0 screw and anchor set. ( If mounting the Blend S afe to wood and you do not plan to use the included anchors, drill 1/8” diameter holes.) Insert the anchors into drilled holes and hammer them into the wall until they are f l ush wi th f ace o f wall. Assemble all of the #1 0 scr ews with a P hillips scr ewdriver into the anchors so the screw heads are sticking out of the wall approximately ½”. Mount the Blend Safe by inserting the screw heads through the keyhole slots in the base and tighten the screws. The water inlet is equipped with a female garden hose fitting (with strainer washer) for attaching a water supply hose. The water in le t may be removed to permit direct connection to a 3/8 in. NPT pipe. The unit is designed so water can be supplied to either side by interchanging the pipe plug with the water inlet. Note: Apply pipe dope, hand-tighten, and then turn 1-1/2 t im es w i th a wr en ch .

DO NOT OVER T IGHTE N.WARNING: Do not use Teflon® tape to seal internal plastic threads as the extra thickn ess of t he ta pe

may cause the p lastic to cr ack. Use a non- welding liquid seala nt instead. The p ush button valves in the top of each station are connected using a hose barb and reinforced tub ing. The bottoms of eac h station are connected to each other using box clips. Additional single-station units can be attached using DEMA kit #66-129. Kit #66-130 is used for attaching dual-station units t o eac h other.

B. PRESSURE INDICATING T EE INST ALL ATION:

female quick disconnect. Attach fem ale end of reinf orced ho se to m ale t hreads of tee, then attach the male en d t o t he female garden hose fitting at the water inlet of the Blend Safe (See Figure 3).

3. CHEMICAL INJECTION ADJUSTMENT:

controlled by metering tips screwed into the proportioner barb. Select a tip using Table 1 or 2 as a guide.

C. CHE MICAL SUP PL Y:

the chemical supply tubing and insert the foot valve end of the tubing into the chemical container. Run the tubing up to the top of the Blend Safe through the holes in the back of the Blend Safe. Install the tubing by pushing tubing over the barb located on the proportioner (Refer to Figure 1). Peel-off gumm ed labels are provided for labeling chemicals.

D. DRIP TRAY:

Two-sided tape or Velcro (not included) may be used to secure drip tray to door.

E. OUTLET TUBING:

located at the bottom of the case. Attach tubing hanger to end of tubing, to hang up when not in use. Do not fo rce o utlet tubing

onto the larger barbs on the proportioner.

4. OPERATION

The Blend Safe is now ready for use. Depres sing a push button op ens the valve allowing water to flow through the che mical proportioner that mixes a chemical water solution at the desired rate. The buttons are spring loaded to prevent accidental overflow if unattended, but may be converted to locking buttons by cutting off the tab at the notch (See Figure 2). Pushing the button and turnin g it a 1/4 turn clockwise at the end of its travel allows the valve to lock on. This makes it unnecessary for the attendant t o hol d the but to n while filling large containers. Turning the button in a counter-clockwise direction will release it, allowing the valve to shut off.

5. SERVICING

A. Proportioner fails to draw chemical:

1. Pinch outlet tube to create back pr es sure, which will cause unit to prime. Then the foot valve keeps the inlet tube primed.

2. Insufficient water supply pressure. 20 PSI is the minimum allowable.

B. Proportioner stops drawing chemical:

1. Inspect foot valve for dried chemical or dirt. Soak in hot water to clean.

2. Propor tioner metering tip clogged with dried chemical. Remove tip and try injecting in hot water. If there is no suction,

3. Inspect proportioner to ensure that there are no mineral deposit build-ups on the nozzle. If so, soak proportioner body in

C. Proportioner continues to draw chemical after water valve closes:

creating a natural siphon. Lower the supply vessel or hang up outlet tube after use.

Remove Blend Saf e cover. Place the chemical con tainer inside the case. Slip a ceramic weight over

Attach to door of unit by inserting notches in back of drip tray through slots in door. Push tray down into place.

Attach one end of the ½” ID tubing to the proportioner outlet barb and run the other end through the hole

Caution: Turn off water supply before servicing.

remove proportioner and soak in hot water to clear interior passages.

deliming solution. (Remove all parts attached to proportioner before soaking in deliming solution.) Note: Use care

when handling hazardous chemicals.

Chemical supply is higher than bottom of discharge tube

D. Valve Malfunction:Check that the button moves freely in & out and that a "click" can be heard when the button is pushed and

released, indicating that the magnet is activating the plunger properly. Remove cover. To inspect internal parts, un scre w m ag net housing and car efully pull off the encl osing tub e so as not to dr op the p lunger , kick- off spring, and s p ace r. Check for dir t or damage impending plunger and kick-off spring movement. Inspect the diaphragm, making sure the two small pin holes (bleed hole) in the diaphragm convolution are clear to allow the valve to close.

Caution: When servic ing unit, be sure that repl acement parts have been installed according to the dr awing.
