INSTALLATION: (See Figure 1 for setup diagram)
This product is designed only to be used as described in this instruction sheet. Adhere to all warnings and
cautions identified in this document.
A.
Mounting and Water Supply:
Locate mounting holes on a permanent surface above sink. Drill holes about 1" deep and insert mounting
anchors. Mount the unit using screws inserted through the keyholes in the case. Secure unit by inserting screws
into the lower 2 holes. The unit needs to be mounted high enough that the sink does not interfere with the outlet
tubes, putting a strain on the proportioners. If this is not possible, tie the outlet tubes together approximately 4"
below where the tubes attach to the proportioners.
The water inlet is equipped with a female garden hose adapter to permit connection to the right hand side of the
unit. The water supply can be attached to the left side of the unit by interchanging the plug in the left-hand side
with the garden hose adapter. Note: The water supply pressure should not exceed 150 psi.
B.
Chemical Supply:
Place the chemical containers in a convenient location not more than 6 ft. below the dispensing unit. Note:
greater lifts will reduce injection capacities. Insert the ends with the foot valves of the 8 ft long, 3/8 in. O.D.
vinyl tubes into the chemical containers. Cut the vinyl tubes to any convenient length that will allow the tubes
to extend from the bottom of the chemical container to the proportioner inlet barb. Slide the ceramic weights
over the 3/8 in. O.D. tubing and down to the foot valves. Repeat this procedure for both containers.
