14. Insert the tube into the pump head as follows.
(i) Ensure that the flow direction indicated by the arrows on the tube exactly correspond
to the arrow on the pump head.
(ii) Hold the tube on either side of the two remaining indicator lines and form a loop.
Insert the formed loop fully into the pump head, taking care not to stretch the tube
(Figure 3.7a).
(iii) Release hold of the inserted tube and allow it to relax to a natural position within the
pump head (Figure 3.7b).
(iv) Close the pump head lever, ensuring that the tube is fully retained within the tube grips
on the side of the pump head (Figure 3.7c). The tube should form a smooth radius when
fitted (Figure 3.7)
CAUTION
• Be careful not to trap fingers when closing the pump head.
NOTE
• The tube must not be stretched when closing the pump head lever as
this may affect the ability of the system to prime, and may also reduce
flow rate.
• The tube must not be pinched with the side of the pump head when
closing the pump head lever as this may affect the ability of the system
to prime, and may also reduce flow rate due to reduced inner diameter
of tube.
• If the system fails to prime within 10 seconds, optimum flow rate may
not be achieved. In this instance it is advised that the tubing be
reloaded into the pump head.
