10 Storage & Handling
Note
Proper handling and storage are important to the operation and maintenance of the
system. These guidelines for handling and storage must be followed, when the system
is in transit, stored or stopped for a long period.
10.1 Storage
The ambient temperature must be 0–45 °C, and the relative humidity must be 20–90 %
RH.
See the Calibration Kit for how to store calibration liquids.
10.2 Long term inactivity
Notice
It is recommended that the following spare parts are kept in stock for when the system
is used again after a long period of inactivity:
• Impeller
• End cover
If the system is inactive for at least 30 days, carry out the following procedure:
•
Isolate the system by shutting off the valves to and from the system.
•
Set Valve 1 and Valve 2 to STOP to prevent water draining from the pH measurement
chamber.
•
Set power to OFF.
•
Remove the pump impeller and secure it to the outside of the pump housing.
•
Clean the strainer.
Preparing the unit for use again:
•
Insert the pump impeller. Rotate the pump shaft by hand.
•
Loosen the end cover prior to startup, to check that the impeller rotates and vents air.
Remember to re-tighten the end cover afterwards.
• Shaft seal
• pH electrode
