**** IMPORTANT ****• Please fully read ALL instructions before beginning the sample.
Failure to follow the enclosed sampling instructions may resultin a contaminated sample.
• Use extreme caution when working around energized electricalequipment. Follow all codes and recommended safety
procedures.
• Never re-use any containers or tubing. Residual gases willcontaminate subsequent samples.
• Make sure all containers remain with their assigned kit. Mixing
kits may result in an administrative charge.
• Review checklist on each kit bag before returning.
• Please return all kits. Discard used plastic tubes.
• Kits not returned within 60 days of shipment may be assessed
a $25 late fee. If you need additional time, please let us know.

**** SAMPLING INSTRUCTIONS ****
TRANSFORMER OIL QUALITY (Plastic Bottle)
1) FILL THE BOTTLE BEFORE SAMPLING WITH THE SYRINGE.
2) Try to sample on a calm, dry day. Rain, high humidity, or blown dust may
seriously affect the quality of the sample.
3) Have a waste container and a spill kit on hand in case a leak is discovered.
4) It may be necessary to use bottled nitrogen to release negative pressure
and allow oil to flow out of the transformer.
5) To ensure that the sample is representative of the oil in the transformer, besure to drain off a small portion into a separate container before filling thebottle. Moisture precipitates to the bottom of the tank and contaminates thesample. Be careful not to let any dirt from the valve get into the sample.
6) Fill the bottle at least 75% full. Make sure the cap is tightened firmly.
7) Write the transformer serial number and all other information on the test
sample record (included). Up to four samples can be recorded on one test
sample sheet.
8) Return each sampling kit inside its original Ziplock bag to contain any leakage. Fill empty space insideshipping box with packing material to secure the sample containers.
9) Return filled sample containers to the address below.
10) Proper disposal of all sampling waste is the responsibility of the customer.

**** SAMPLING INSTRUCTIONS ****DISSOLVED GAS-IN-OIL ANALYSIS (Glass Syringe and Plastic Tube)
1) Have a waste oil container and a spill kit on hand in the event a leak is discovered.
2) If necessary, use bottled nitrogen to release negative pressure and allow oil to flow out of the transformer.
3) DO NOT reuse the plastic tubing. Gases in the oil, especiallyacetylene, may carry over from one sample to another.
4) Attach the plastic tube to the transformer valve, or an adapter thatfits the tube, to ensure a leak-tight connection. Open the transformervalve slowly, draining oil through the tube to an overflow pan, until oil
is running clear and free of debris and water. Close the transformervalve.
5) Affix the open end of the tube to the tip of the syringe. Open thetransformer valve slowly, then open the valve stem to the syringe byturning it in the direction of the drain port (FILLING). Fillapproximately 10 mls (ccs) of oil and close the transformer valve.
While holding the syringe, tip pointed up, open the syringe valve
stem towards the tip (BLEEDING) and empty syringe contents into
the waste oil pan until all the air bubbles are removed from thesyringe. This process is meant to rid syringe space of air bubbles.
6) Open the syringe valve (FILLING) and allow syringe to fill itself bypressure and gravity, while holding onto the syringe with the tip pointing upward. DO NOT pull back on thebarrel. This will cause bubble formation. If gas bubbles form, do not attempt to drain them, as they will
now be part of the sample. Fill the syringe to the 40 ml (cc) level. If using smaller 30 ml (cc) syringes, fillsyringe to about 1/2" past the 30 ml (cc) line while making sure the filled syringe will fit into the box.

7) Close the transformer valve followed by the syringe valve stem (CLOSED). Detach the tube very carefully
while holding onto syringe tip firmly (if tip becomes loose or dislodged oil contents could leak out). Discard
the tube and waste oil properly. Place the syringe in the box immediately to avoid exposure to light andcomplete the test sample record (included). Package and ship your samples carefully to Alfa Transformer
as soon as possible after sampling. See previous page for shipping instructions.

Electrical Insulating Oils. It is the responsibility of the customer to perform the sampling, handling, shipping, and any related activity consistent withproper servicing of electrical equipment.
