Installation and Operation:
1. Findsuitableplaceclose to watersourcefor unit.Mountingbracket should beinstalled approx. 5' fromfloor.Level bracket
& mark holes. Drill 9/32" holes & install mounting anchors and screws in bracket.
2. Hang cabinet on bracket. Mark hole for lower cabinet screw. Remove cabinet & drill 9/32" hole. Install anchor and
screw to lower unit hole. When mounting unit do not mount any higher than 5 feet from the floor. Also, never mount
your concentrate container higher than the unit.
3. Select 4 metering tips for the selector valve attached to the low flow (gray) eductor, and 2 tips for the select valve attached
to the high flow (yellow) eductor. Push each tip firmly into a separate hose barb extending from the selector valve.
NOTE: The two hose barbs on the select valve attached to the high flow (yellow) eductor have been blocked with clear
tips for dispensing water. These may be replaced with colored metering tips if
additionalhigh flowproducts aredesired.NOTE:additionalpickup lineswill beneeded.
4. Cut tubing provided into separate supply tubes for each product to be dispensed.
Supply tubes should reach from hose barbs on the selector valve body to bottom of
concentrate containers. Slide ceramic weights over one end of each tube
and slide foot strainer into the same ends of the tubes. Remember to include check
valves in the proper places in the supply tubing, colored end facing eductor body, as
shown (see diagram Page 3). Additional tubing is provided for drain hole in bottle fill
drip tray. NOTE: When routing pickup line(s) through unit, direct pickup line
through clip(s) in cabinet back to ensure proper operation. (see diagram1)
5. Place strainer ends of supply tubes into concentrate containers. REMEMBER
TO CHECK STRAINERS PERIODICALLY FOR CLOGGING:CLEAN IF NECESSARY. DIAGRAM 1
6. Replace unit cover. Be sure cover is labeled to allow identification of products to be dispensed.
7. Connect water supply hose to water inlet swivel. (Minimum 25 PSI pressure, with water running, is required for proper
operation.) Turn on water supply.
8. Purge air from system by repeated rapid depressions of activating devices. The bottle fill activates by inserting a spray
bottle over the discharge tube and lifting lever until flow starts. To stop flow, lower bottle off discharge tube. The bucket
fill activates by holding and depressing lever of gun. To stop flow, release lever. The lever can be locked on by flipping
clip to hold lever. CAUTION: Lever must be manually unlocked to stop flow. Overflow will result if left locked
in open position.
* In hard water areas, scale may form inside the discharge end of the eductor, as well as in other areas of the unit that are
exposed to water. This scale may be removed by soaking the eductor in a descaling solution (deliming solution). To remove
an eductor located in the cabinet, firmly grasp water valve and unthread eductor. Replace in same manner. Alternatively,
a scaled eductor can be cleaned (or kept from scaling) by drawing the descaling solution through the unit. Operate the unit
with the suction tube in the descaling solution. Operate the unit until solution is drawn consistently, then flush the unit by
drawing clear water through it for a minute. Replace concentrate container and put suction tube into concentrate.

Metering Tip Selection:
The final concentration of the dispensed solution is
relatedtoboththesizeofthemeteringtipopeningand
the viscosity of the liquid being siphoned. For water-
thin products, the chart at right can be used as a
guideline. If product is noticeably thicker than water,
consult the Measurement of Concentration Proce-
dure below to achieve your desired water-to-product
ratio. Because dilution can vary with water tempera-
ture and pressure, actual dilution achieved can only
beascertained byusing theMeasurement ofConcen-
tration Procedure. The clear, undrilled tip is provided
to permit drilling to size not listed should you need a
dilution ratio that falls between standard tip sizes.
NOTE: Refer to parts diagram if unfamiliar with
names of system components.
Measurement of Concentration:
You can determine the dispensed water-to-product
ratioforanymeteringtipsizeandproductviscosity.All
that is required is to operate the primed dispenser for
a minute or so and note two things: the amount of
dispensed solution, and the amount of concentrate
used in preparation of the solution dispensed. The
water-to-product ratio is then calculated as follows:
Dilution Ratio (X:1) where X = Amount of Mixed Solution — Amount of Concentrate Drawn
Amount of Concentrate Drawn
Dilution Ratio, then, equals X parts water to one part concentrate (X:1). If the test does not yield the desired ratio, choose
a different tip and repeat the test. Alternative methods to this test are 1) pH (using litmus paper), and 2) titration. Contact
your concentrate supplier for further information on these alternative methods and the materials required to perform them.
