CONTAINER SAMPLES
Although we do not recommend bottle or bucket sampling if accuracy is to be achieved, it is
sometimes impractical to obtain pressure to force the fuel sample through the detector pad. For
this reason, we offer as an option, the model GTP-165 stainless steel syringe with an attachment
fitting P/N HN25 (hex nipple). When this nipple is screwed into the outlet of the detector pad holder,
the tapered fitting on the syringe will seal in the small end of the nipple. To pull a sample through
the detector pad, place the entire detector pad housing in the fuel sample container and pull the
syringe handle all the way out. Expel the fuel from the syringe after disconnecting it from the nip-
ple fitting by pushing the handle all the way in while holding the syringe fitting over the polyethylene
bottle in the kit. Repeat this procedure until the required fuel volume has been passed through
the detector pad.
SPOILAGE OF WATER DETECTOR PADS
These pads are heat sealed in triple-walled envelopes to insure that moisture from the air will not
reach the sodium fluorescein. Pads that were stored for 8 years were still in good condition, but
statistical studies have proved that up to 4 or 5% of the envelopes have enough water permeability
to spoil the pads. This occurs in the first six months. A spoiled pad is easily identified by its ye//ow
color. The operator should inspect every pad before it is used. If it is not orange in color, it must
not be used. Spoiled pads will cause a high reading, if used.
CARE OF NEW, SERIES Ill ULTRAVIOLET LIGHT
The model number of this unit is GTP-2201. It contains 4 basic items:
Battery Pack Assembly — GTP-2324
Light Board Assembly — GTP-2382
Power Board Assembly — GTP-2383 (120V 50-60 HZ)
Switch Bracket Assembly — GTP-2381
Power Board Assembly — GTP-2383 (220V 50 HZ)
To replace anyone of these components, separate the light unit from the comparator chamber by
removing 4 screws in the base. Then remove all 5 slotted head screws which hold the side cover
plate on the light unit.
