5. Preventative Maintenance
5.1 Cleaning Requirements
Caution: Always check that the instrument is switched off, the power cord is unplugged, and the analyzer is
allowed to cool before proceeding with preventative maintenance tasks.
Tubing and Fluidics
When the PeCOD® will not be in use for several hours, prime Port A with DI water. The block and sensor can
remain in the PeCOD® for up to three weeks stored in this way. External tubing can be purchased as a PM kit.
Contact your local PeCOD® representative for more details on PM kits suitable for your configuration.
Analyzer
To clean the external surface; wipe with a soft, damp cloth and a mild household grade detergent (if necessary).
Make sure no water penetrates the analyzer.
Sensor
Use a lint free tissue to clean or dry surfaces.
5.2 Battery Pack
An optional battery pack for portable field use is available from MANTECH and your local MANTECH authorized
representative. This battery pack should be plugged into the back of the L100 (for field use) and can be recharged
when plugged into an L100 that is connected to an external power supply. The pack will provide up to 8 hours of
continuous operation.
5.3 System Storage
General Guidelines
The sensor and electrode block may be stored in the PeCOD® for up to three weeks, ensure that the PeCOD® has
been primed with DI water to keep the electrode block hydrated. If the unit will not be used for more than three
weeks:
•
Prime Port A and Port B with DI water, three times. Repeat with air, priming three times. This ensures
that the fluidics lines are free of liquid.
•
Remove the electrode block and sensor, and fill the block with deionized water (see below). Place the
sensor in its original package when not in use as it is light sensitive.
Flushing and Storing the Electrode Block
1. The electrode block should always be kept hydrated. Flushing with DI water is a general preventative
maintenance and troubleshooting procedure to maintain the life of the electrode block and is necessary
for short term storage. Long term storage requires the block to be filled with 3M NaCl.
2. Using the syringe and tips provided in the starter kit, fill the syringe with DI water and find the
appropriate sized tip for the hole indicated below. Push DI water through the hole. This will flush out the
internal channel and come out the other side. Refill the syringe and repeat the process 5-6 times.
