OPERATION
Connecting the chemical supply
(1) Locate chemical container(s) below the proportioner.
(2) Insert the foot - valve end of the 3/8" vinyl tube into each container (use ceramic
weight if necessary to sink tube to bottom).
(3) For all ports, connect the inlet tube over the colored metering tip — secure with
a plastic zip tie.
Installing bucket - fill or bottle fill tube (optional)
(1) Connect the bucket or bottle fill tube with the flow restrictor (plastic insert) end
closest to the venturi body.
(2) Secure tube to venturi body with tie wraps provided.
Dispensing chemical - water mix
(1) Select the desired product with the selector knob (for dial operated units).
(2) Press the button on the front cover—release button when container is full.
(3) If desired, the button can be “ locked ” in the ON position for filling large
containers such as mop buckets or floor scrubbers. Simply push the latch into
the button when pressed in. To release, push latch away from button.
DIAL POSITION
The selector dial has 4 positions that correspond to the 4 chemical inlet ports (see
figure to the right). Labels can be applied to the cover of the unit to identify where
to point the dial for each particular chemical. When inserting metering tips, be sure
to match up the correct tip for the chemical that will be used on each port.
CHOOSING THE FLOW RATE
FLEX - GAP VENTURI
For the Flex - Gap systems, the flow rate is controlled by a venturi insert located
inside bottom of the Flex - gap housing.
WHITE Venturi insert (2200106) = 1 GPM
BLACK Venturi insert (2200105) = 4 GPM
To change the venturi insert.
(1) Remove the cover by gently snapping it away from the unit.
(2) Disconnect tubing from Flex - Gap housing.
(3) Twist the Flex - Gap housing counter - clockwise to remove it from the water valve
body.
(4) Push out existing venturi tube by inserting a pen up through the bottom of the
Flex - Gap housing (note the order of the parts as they are removed from the flex -
gap/venturi housing). See Figure 1
(5) Insert the new venturi insert (for the desired flow rate) into the Flex - Gap housing,
ensuring that it seats firmly. Place the flex - gap parts in the order removed from
the previous step.
(6) Twist the Flex - Gap housing clockwise to reattach it to the water valve.
