1. Turn pump on.
2. Feed one end of mix pump hose into the entering
or pickup hose side (left) of black cover.
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 6" (15cm) remains on the entering side.
5. Turn pump off.
6. Connect mix pump hose to the elbow fi tting
(located on the left side of the mix line manifold)
using small hose clamp. Be careful not to twist
the mix hose.
7. Turn pump on.
8. Allow remaining 6" (15cm) of tubing to feed through
pump until hose adapter prevents further feeding.
9. Turn pump off.
10. Connect free end of mix pump hose to 3-way Tee
as shown in Figure 2-4. When all connections are
complete the 3- way Tee must be lower than the
black pump housing.
B. MIX PICKUP HOSE INSTALLATION
The F431 machine may be connected to standard mix
containers or prepacked mix bags. One, 5 gallon mix bag
may be connected to each freezing cylinder or two 2-1/2
gallon bags may be connected on each side. Follow the
instructions below that match your confi guration.
When Using One Mix Container Per Side:
1. Connect a 2" (5cm) length of 3/8" (9,5mm)
ID plastic food grade tubing to the mix pickup
assembly. Secure with hose clamps. Then
place assembly through hole in cover and install
retaining clip (see Figure 2-4 and 2-5).
2. Connect the free end of tubing to the mix check
valve. Observe direction of check valve fl ow arrow.
Secure with hose clamp. Connect 24" (61cm)
length of 3/8" (9,5mm) ID plastic food grade tubing
to free end of check valve and secure with hose
clamp.
CAUTION
Risk of product damage
Air/mix Tee must remain below the black cover/
clamp. If Tee is above the pump, mix will drain to
the air compressor resulting in pump damage.
