G. Connect the new mix pump hose to the pickup
hose adapter using the small clamp.
H. Feed one end of the mix pump hose into the
pickup hose side (left) of the 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.
I. Gently push the hose into the black cover until it
begins to feed.
J. Allow the hose to feed itself through the pump until
about 6" (15cm) remains on the entering side.
K. Turn pump off.
L. Connect the mix pump hose to the elbow fitting
(located on the left side of the mix line manifold)
using a small hose clamp. Be careful not to twist
the mix hose.
M. Turn the pump on.
N. Allow the remaining 6" (15cm) of tubing to feed
through the pump until the hose adapter prevents
further feeding.
O. 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, the mix may
drain into the air compressor, resulting in pump dam-
age.
P. Connect the free end of the mix pump hose to the
3-way Tee. When all connections are complete,
the 3-way Tee must be lower than the black pump
housing.
Q. The pump is now ready to sanitize.
