Figure 2-2 Mix Hose Installation
NOTE
2. Feed one end of the mix pump hose into the
entering or pickup hose side (left) of black cover
(Fig 2-2).
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.
9. Turn the pump off.
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.
