Hot-Shot™
7
SET-UP #2 (SERIES) -
BEST FOR LONG LENGTHS OF PIPE
1. Make all connections EXCEPT leave the clamp on one end of
the pipe free.
2. Touch the free clamp to the pipe for an instant. Observe the
amount of spark.
A. Strong spark - Polarity is correct.
B. None or weak spark - Polarity is incorrect. To correct the po-
larity: Turn over one of the 115v plugs, OR interchange the
cable leads on one of the Hot-Shot units.
4. Repeat the test until no spark is seen.
5. When polarity is determined to be correct, attach the clamps.
NOTE: Two correctly connected Hot-Shots will double the thaw-
ing action. If more heat is required, a larger Hot-Shot unit and
qualified operator must be used.
THAWING TIMES
The times in the charts below are approximate and under ideal condi-
tions. Actual times will vary depending upon type of pipe, diameter,
gauge, and length of cable, etc.
Note: Copper pipe will not heat up as fast as iron pipe, so allow
about a 30 percent longer thawing time.
Note: Longer cables must also be a larger gauge. If smaller diameter
cables are used, current will be reduced.

SET-UP #1 (PARALLEL) -
BEST FOR LARGE DIAMETER PIPES
1. Make the two pipe connections on one side of the pipe, and plug
in both units.
2. Touch the other two clamps together for an instant. Observe the
amount of spark.
A. None or weak spark - Polarity is correct.
B. Strong spark - Polarity is incorrect. To correct the polarity:
Turn over one of the 115v plugs, OR interchange the cable
leads on one of the Hot-Shot units.
3. Repeat the test until no spark is seen.
4. When polarity is determined to be correct, attach the clamps.

MAINTENANCE
1. Replace damaged, frayed, or worn cables.
2. Periodically clean terminal blocks, lugs, and clamps with steel
wool and emery cloth.
3. Replace damaged, frayed, or worn power cord.
4. Store Hot-Shot indoors, in a dry location.
