CertainTeedH To Larry Meqarqee Subject Mail Codejj(260 Riverside AIR SAMPLING EQUIPMENT LOAN y Jam's L. Woodson// Mail Code 1125/4 Date Ext. 7713 October 23, 1986 Enclosed are two DuPont P4000 Multiflow Pumps, a multi-charger and an instruction booklet. I have precalibrated the pumps; the calibration sheet is attached. The pumps are easy to use, reliable and hold their flow rates constant but should still be calibrated after every sampling day. To turn the pump on, remove the faceplate, in the lower right hand corner is the on/off switch. All the other switches pertain to preset start and stop modes and should remain in their present position "manual" for your use. If you should have any questions or problems, call me.
