2. INSTALLATION:
Note: All installations must conform to local plumbing codes and use the approved backflow preventers. Pressure
indicating tee is to be installed with existing faucets according to local plumbing codes in the state of Wisconsin and any
other state that requires the use of a pressure indicating tee.
WARNING: Water supply should not exceed 125 psi and water temperature must not exceed 150°F.
A. Mounting & Water Supply: Remove the two cover retainer screws and the cover from the Blend Center assembly. Any
number of Blend Centers can be coupled together by first removing the pipe plugs in all but the last unit, then connecting
the male hose thread of one unit to the female inlet hose adapter of the next unit. Mount the unit(s) in position on the wall
and locate the position for the mounting screws. Only two screws are necessary to mount up to four units coupled together.
Drill all of the holes into the drywall using a ¼" diameter bit for use with the included #10 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.) Insert the
anchors into drilled holes and hammer them into the wall until they are flush with face of wall. Mount the units(s) to the
wall and replace the covers and screws.
The water inlet is equipped with a female garden hose fitting (with strainer washer) for attaching a water supply hose. The
unit is designed so water can be supplied to either side by interchanging the pipe plug and the female hose fitting. Note:
Apply pipe dope, hand-tighten, and then turn 1-1/2 times with a wrench. DO NOT OVER TIGHTEN.
WARNING: Do not use Teflon® tape to seal internal plastic threads as the extra thickness of the tape may
cause the plastic to crack. Use a non-welding liquid sealant instead.
B. Pressure Indicating Tee Installation: Screw female quick
disconnect to faucet and attach pressure indicating tee to female
quick disconnect. Attach female end of reinforced hose to male
threads of tee, then attach the male end to the female garden
hose fitting at the water inlet of the Blend Center (See Figure to
the right).
C. Chemical Supply: Place the chemical containers in a
convenient location not more than 6 feet below the Blend
Center (greater lifts will reduce injection capacities).
ceramic weight over the chemical supply tubing and insert the
foot valve end of the tubing into the chemical container. Cut
the vinyl tubing to any convenient length that will allow the
chemical supply tubing to extend from the bottom of the
chemical container to the proportioner inlet barb. (See Figure
1) Install the tubing by pushing tubing over the barb located on
the proportioner. Gummed labels are provided for labeling
chemicals.
D. Outlet Tubing: Cut the 1/2" I.D. outlet tubing to the desired
length and attach it to the proportioner outlet barb. NOTE: DO
NOT force outlet tubing onto the larger barbs on the proportioner.
