fill
Warnings
All installations must conform to
local plumbing codes and use
approved backflow prevention
devices. A 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

Overall Dimensions
Installation & Preparation
1. Identify desired location of dispenser. Remove cardboard mounting template from packaging, place
against wall and mark hole locations using the template as a guide.
[For accuracy, use level with template to ensure the dispenser is level on the wall]
2. Install all four supplied anchors into marked hole locations from step 1. Using supplied screws, install
top two screws and hang dispenser from them. Install bottom two screws through dispenser holes
into the anchors.
3. Tighten screws against dispenser to assure a secure fit.
4. Install Drip Tray by sliding into place against
tab in back of drip tray holder.
[Optional: Drill 3/16” hole into drip tray barb and
attach ¼” ID hose (not supplied) for draining
chemical from drip tray (Figure 1)

Installation & Preparation Cont’d
Steps 5 through 7 explain how to install metering tips. Metering tips will be installed at the two check
valves located in each compartment. Check valves to bucket fill have a plastic ring, and check valves
for bottle fill do not.
5. To install metering tips, locate the correct
check valve in each compartment. Identify
desired metering tip based on color and dilution
rate on the tip chart for bottle and bucket filling
(Figure 2)
Figure 2
6. Screw metering tip clockwise into exposed
threaded check valve barb
Note: A blank tip can be used to prevent a
product from dispensing at bottle or bucket fill
7. For SafeLink cap and tubing: secure the tubing
over the exposed check valve barb (Figure 3)
For Open container: Measure bulk tubing
needed and cut to length. Install ceramic
weight and foot valve at base of tubing.
Secure top of tubing over the exposed check
valve barb
Note: Softening the tube with hot water will
allow the tube to fit over the barb with ease
Figure 3
8. Position chemical container into each
compartment in desired position and connect
SafeLink cap or install tubing w foot valve and
ceramic weight into open container (Figure 4)
9. Close and lock the cabinet doors
Figure 4
10. Connect the supplied water hose to your water
source and activate the dispenser by selecting
a position on the dial and using either the
bucket or bottle fill activation point (Figure 5)

raise the bottle to engage the u-shaped lever of
the bottle fill assembly
2. To stop filling, lower the bottle and the lever will
disengage
3. Be careful when removing the spray bottle so
as to not splash residual chemical
Figure 7
Dispenser Activation Points – Push Button Bucket Fill (if equipped) (Figure 8)
1. To start the flow of diluted chemical, press
button on unit above selector dial
2. For continuous flow, twist button clockwise
3. To disengage, release button or twist button
counterclockwise
Figure 8
Dispenser Activation Points – Remote Fill (if equipped) (Figure 9)
1. To start the flow of diluted chemical, press
trigger on handle of fill gun
2. For continuous flow, while trigger is pressed,
slide the red lever to one side and release
trigger
3. To disengage, simply press the trigger again
and the red lever will move out of position

Troubleshooting
Symptom Probable Cause Remedy
Proportioner
fails to draw
chemical
properly.
1. Insufficient water supply pressure.
2. Safelink cap has chemical build-up
(if installed).
3. The outlet tubing might be pinched
closed.
4. Chemical metering tip is clogged.
5. Mineral deposits are built up in the
in the proportioner.
1. 20 PSI is the minimum allowable
pressure.
2. Soak in hot water to clean.
3. Straighten out the tubing to remove the
restriction.
4. Remove metering tip from check valve
and replace with new one.
5. Soak proportioner in delimer or off the
shelf product such as CLR to clean
mineral deposits.
“Air Gap”
Proportioner is
dripping or
spraying a mist
(fan pattern) of
water.
1. Mineral deposits are located on Air
Gap nozzle. 1. Soak nozzle and inlet screen in delimer or off the shelf product such as CLR to clean
and remove mineral deposits.
Water valve is
not shutting off
completely.
1. “Sliding lever” return spring may be
missing on Remote Fill gun.
2. “Sliding lever” is not returning all
the way down due to interference
between the sliding lever and either
the chemical supply and/or outlet
tubing.
3. Bucket fill outlet hose is catching
the bottom edge of the sliding lever
during normal usage.
4. Bottle Fill valve will not shutoff.
1. Remove cover and visually check for
sliding lever return spring. Replace if
missing.
2. Remove cover and visually check for any
tubes rubbing the sliding lever. Routing of
chemical supply and outlet tubing must not
restrict the movement of the sliding lever.
Reroute tubing.
3. Don’t pull the bucket fill outlet hose too
tight from either side otherwise sliding
lever may not return properly.
4. Make sure bottle fill hose is not pressed
against the lever.
Water valve is
leaking. 1. Barbed nut is too loose. 1. Shut water supply off first. Hand-tighten the barbed nut. Do not over tighten w/tool.
Threaded
connections
are leaking
water.
1. The connection between the
dispenser and water supply line is
too loose or rubber washer is
missing.
2. Backflow prevention devices
and/or proportioners are too loose.
1. Shut water supply off first. Carefully
tighten the female hose coupling on the
dispenser to the inlet water supply line.
Do not over tighten.
2. Tighten loose connection(s) with tools if
necessary. Do not over tighten if using
tools.
Selector valve
is not selecting
the correct
chemical
1. The transmission assembly is
malfunctioning. 1. Make sure the transmission is engaged with the selector valves. If problem
persists, replace transmission assembly.
Water is
leaking in
between the
two water
valves
1. Plastic fitting connecting the water
valves has lost its seal. 1. Remove the plastic fitting and apply silicone grease to both O-rings and
reattach to the valves.
