Repower the instrument, if necessary. From the Service menu, Monitor tab, check pump function for proper flow direction.
Also listen for any unusual sounds that suggest strain on the pump motor. This may indicate binding or twisting of the
newly installed tubing.
9.6.1.2 Solenoid Valve Tubing Replacement
Before changing solenoid valve tubing first study the tubing placement carefully. The sample flows through the outer slot
of the solenoid valve and the antiseptic flows through the inner slot (closest to the 2960 case). The sample and antiseptic
lines are connected together with a Y-shaped fitting on the outlet side of the solenoid valve.
To change solenoid valve tubing, grasp the tubing at each end close to the valve and pull it up out of the slot.
To install the solenoid valve tubing, refer to the instructions below.
NOTE: The following procedure should be followed when installing the solenoid tubing to ensure correct valve
operation and prevent premature tubing failure.
1. From the Service menu, Monitor tab, touch the Opened Valve [Antiseptic] button and change it to [Sample] to
energize the solenoid.
2. Install the Sample Tubing in the outer solenoid valve slot. Make sure that the tubing lies completely at the bottom of
the slot. Do not stretch the tubing.
3. Touch the Opened Valve [Sample] button and change it to [Antiseptic] to de-energize the solenoid.
4. Install the Anti-septic Tubing in the inner solenoid valve slot. Make sure that the tubing lies completely at the bottom of
the slot. Do not stretch the tubing.
NOTE: If the tubing is stretched, the walls may become too thin for the valve to operate properly.
9.6.2 Monitor Sample Cup
There are two approaches to cleaning the Monitor sample cup.
• You may use the monitor pump to draw cleaning solution through the system. See Section 9.1 for a list of
authorized cleaning solutions. To clean the "funnel" near the tip of the cup, use a swab or direct a stream of
cleaning agent at the area while the pump is running. Remember, waste must be actively removed from the cup.
Gravity alone will not insure draining of the cup.
• Alternatively, you may remove the cup and clean it. Note: Do not attempt to remove the stainless steel inlet tube
from the cup. Remember to realign the sipper with the cup before initiating another monitor run.
The cup body is machined from acetyl copolymer (tradename, Celcon). The outlet fitting is polypropylene. Cleaning the
cup with boiling water and/or steam sterilization will not harm the cup parts.
