5.
Install a new battery pack assembly into the PDM3700 unit.
6.
Check the mass transducer O-rings and lubricate them, if necessary.
7.
Install the PDM3700 cover panel (refer to the instructions earlier in
this chapter for information on opening the case).
8.
Install the mass transducer into the PDM3700 unit.
9.
Press the “A” (“WAKE UP”) button on the top panel of the PDM3700
unit to ensure that the display screen appears.
10.
If the display screen does not appear, open the case and double-check
the battery connections. Reassemble the case, and press the “A”
(“WAKE UP”) button again. If the display screen does not appear,
contact Thermo Fisher Scientific.
11.
Properly dispose of the used PDM3700 battery packs. Recycling is the
preferred method of disposal. Contact Thermo Fisher Scientific for
further information. Do not dispose of the battery packs in fire or heat.
CAUTION
Always properly dispose of the PDM3700 battery packs
(recycling is preferable, contact Thermo Fisher Scientific for further
information). Do not dispose of the battery packs in fire or heat.

12.
Perform a sample line leak check and a case leak check.
If it becomes difficult to install the mass transducer, lubricate the two O-
rings located inside the top of the mass transducer section. Because this
procedure is easier to complete with the cover panel removed, check the
mass transducer O-rings while replacing the battery pack assemblies (or as
necessary). Tool/materials needed for this procedure:
●
Phillips screwdriver
●
Cotton swab
●
Silicone compound.
WARNING
Whenever the PDM3700 case is opened for maintenance, you
must perform a case leak check after reassembling the case. The system
must pass the case leak check prior to operating the instrument. Correct the
