9. Turn the pump off.
CAUTION
Risk of Product Damage
Air/Mix Tee must remain below the black cover
clamp. If the Tee is above the pump, mix may drain
into the air compressor resulting in pump damage.
10. Connect the free end of the mix pump hose to
the 3-way Tee (Fig. 2-3). When all connections
are complete, the 3-way Tee must be lower than
the black pump housing.
B. MIX PICKUP HOSE INSTALLATION
The machine may be connected to the standard mix
container or up to three prepacked mix bags. Follow the
instructions below that match your confi guration.
Standard Connection:
1. Place the mix pickup assembly through the hole
in the cover and install the retaining clip.
2. Connect a 24” (61cm) length of 3/8” (9,5mm)
ID plastic food grade tubing to the mix pickup
assembly. Secure with a hose clamp.
3. Connect the elbow fi tting to the free end of the
tubing. Connect the opposite end of the elbow
to 1/4” ID tan tubing on the left side of the pump
head. Secure with hose clamps (Fig. 2-3).
2.5 MIX PUMP
A. MIX PUMP HOSE INSTALLATION
Follow the steps below to install the mix pump hose in
the cabinet part of the machine.
1. Turn the mix pump on by pressing the Pump On/
Off button on the touchpad.
2. Feed one end of the mix pump hose into the
entering or pickup hose side (left) of black cover
(Fig 2-2).
NOTE
Feed the tube into the clamp so the natural curve of
the tube is towards the outside of the black cover.
This prevents the hose from looping around the
black cover twice.
3. Gently push the hose into the black cover until it
begins to feed.
4. Allow the hose to feed itself through the pump
until about 6” (15cm) remains on the entering
side.
5. Turn the pump off.
6. Connect the mix pump hose to the elbow fi tting
(located on the left side of the mix line manifold)
using a small hose clamp. Be careful not to twist
the mix hose.
7. Turn the pump on.
8. Allow the remaining 6” (15cm) of tubing to feed
through pump until the hose adapter prevents
further feeding.
