TUBE LIFE WARNING?
__ __ __ __ 04:
30:02
Enter t he maximum number o f revolutions the tubing will accept
before the sampler issues a pump tube warning. The number
entered is in terms of thousands (in other words it adds 3 0’s to the
end of the number entered) so if 0500 is entered, the sampler
would see it as 500,000. Entering 4000 equals 4,000,000 and
0060 would be 60,000, etc. When the number of revolutions meet
or exceed the pump counts set by the user, a pump life warning
will be issued. T he default is 1,000,000.
Cleaning the Control Panel and Electronics Enclosure
Use a mild cleaning solution and wipe with a soft, lint-free cloth. T he clear window on the membrane keypad
is easily scratched, so be very careful when cleaning. The exterior of the electronics enclosure is constructed
of thick walled injection molded structural resin and is designed to withstand a wide variety of conditions.
The unit conforms to NEMA 4X,6 criteria, when the unit is latched shut. Please be sure to close and latch
the unit when not programming. T his will ensure t hat the keypad is not exposed t o the elements and will
increase its useful life.
CAUTION: Do not use harsh cleaners (detergents, solvents, etc.) which can damage the panel surface.
Do not use abrasives which can scratch the panel and fog the window above the LCD
display.
Cleaning the Wetted Parts
Note: Solvents and solvent contaminated fluids must be disposed of according to approved procedures.
Manning Environmental Inc. recommends instituting a cleaning regime
for the sampling equipment. The following are a few of the many
reasons why a cleaning regime is important:
1. It validates t hat t he samples t aken will be as free as
possible from constituents that are not contained
within t he sample it self.
2. It contributes to ensuring that the statistical validity
of t he samples being examined will be maximized
by reducing systematic error, if t he regime is followed very closely.
3. It contributes to the longevity of the sampling equipment.
4. It provides documentation for challenged results.
For a detailed description of a cleaning protocol refer to U.S. Environmental Protection Agency Publications
