Place a wooden or plastic rack into the water bath.
	Place the Deltaphase Isothermal Pad onto the rack in the water bath. Caution: Verify that the pad is not touching the bottom or sides of the water bath because the plastic covering of the pad may stick to the water bath. This would damage the pad beyond repair.
	Heat the pad in the water bath for at least 1 hour until the consistency of the pad changes from a solid to a liquid state.  The color will also change from white to a clear transparent state. You may notice that the clear liquid will contain small white beads which will indicate that the pad is ready for use.  The temperature of the pad will be stable at 37° C

The following two activation methods will wear out the life of the pads faster than the water bath method.  (Approximately 3 months depending upon frequency of use)

Microwave Oven

	Set the microwave on high
	Set the microwave timer control to 45 seconds and let it run for that period of time.
	Remove the pad and knead it.
	Return the pad to the Microwave oven and repeat the above steps until the consistency of the pad changes from a solid to a liquid state. The color will also change from white to a clear transparent state. You may notice that tile clear liquid will contain small white beads which will indicate that the pad is ready for use. The temperature of the pad will be stable at 37°C.

Regular Lab Oven

	Set the lab oven temperature control to 42° or 43°C.
	Place the Deltaphase Isothermal pad on the middle rack in the oven. Caution: Be sure that the rack does not have any sharp burrs or other places where the plastic bag can be punctured or cut; otherwise, the pad can be damaged beyond repair.
	Heat the pad for several hours in the oven until the consistency of the pad changes from a solid to a liquid state. The color will also change from white to a clear transparent state. You may notice that the clear liquid will contain small white beads which will indicate that the pad is ready for use. The temperature of the pad will be stable at 37°C.
	Some people prefer to place the pad in the oven overnight to activate it before using it the following day. This procedure has been successful.

Do not store activated pads at temperatures exceeding 50°C.

Special Note: The length of time that the Deltaphase Isothermal Pad can maintain its 37°C temperature may be further maximized by placing the foam insulator (included with shipment) underneath the pad. This insulation will keep any heat from being transferred to the table. A towel covering the exposed pad around the animal will also help extend the time it holds the 37°C temperature.
