LaMotte Air Pollution Sampling & Measurement - Manual (Page 9)

NOTE: To avoid introducing residue or foam into the pump a trap
may be constructed by adding an empty impinger to the flexible
tubing between the impinging tube with the absorbing solution and
the pump intake fitting. Attach the flexible tubing leading from the
impinging tube outlet to the intake of the empty impinger. Use an
additional length of tubing to attach the outlet tube of the empty
impinger to the pump intake fitting.
5.
At the end of the sampling period, turn switch to the “OFF” position.
Disconnect impinging apparatus and remove from holder.
6.
The absorbing solution is then subjected to the testing procedure as
outlined in the individual air pollution test instructions.
AC OPERATION
The Model BD Pump may be operated with an AC adapter (Code 1744)
by plugging jack into designated receptacle.
BATTERY REPLACEMENT
Turn switch to the “OFF” position and remove panel. The battery holder
and batteries are located under the panel. Remove old batteries and
snap new batteries into battery holder making sure batteries are aligned
properly to their positive and negative terminals as indicated.
Misalignment of the batteries may result in permanent damage to the
pump. After batteries have been replaced, return panel and secure by
tightening the four corner screws.
MAINTENANCE OF FLOWMETER
The only maintenance normally required is occasional cleaning of the
flowmeter to assure reliable operation and good float visibility. Please
contact LaMotte Company’s Technical Service Department
(800-344-3100 or www.lamotte.com) for instructions and assistance
with disassembly and cleaning of the flowmeter.
STORAGE
To reduce the effect of possible variation introduced by the interval of
collection and analysis, the time period should be kept as short as
possible, and preferably of the same duration. The sample should be
kept from exposure to heat and light. If the analysis cannot be made
immediately after the sample collection, the sample may be stored at a
low temperature.
