Hot-Shot™
5. Do not leave unit unattended while thawing. It is dangerous to
leave any tool unattended during operation.
6. Do not touch the clamp tips or cable connections. Reduces
the risk of burns.
7. Do not operate machine if operator or machine is standing
in water. Will increase risk of electrical shock.
8. Do not operate unit with the housing removed. Exposure to
internal parts may result in injury.
9. Wear safety glasses and rubber soled, non-slip shoes. Use
of this safety equipment may prevent serious injury.
10. Use cable and clamps provided with unit. Incorrect cables
may result in overheating of the wires.
11. Keep clamps away from combustible materials or articles
that can be damaged by heat. Clamp tips become hot during
use.
12. Tool is made to thaw frozen iron or copper pipes. Follow the
instructions on proper use. Other uses or may increase risk of
injury.
INTRODUCTION
A frozen water pipe can be thawed very quickly by passing low volt-
age high current electricity through the frozen pipe. Plastic pipe will
not conduct electricity so this method will not work on plastic
pipe. There must be unfrozen water under standard water pressure
on one side of the frozen part of the pipe, and an open faucet on the
other.
When thawing a frozen section of water pipe, heat the pipe only
enough to melt a thin film of ice in the inside of the pipe. A faucet
must be opened in the unfrozen part of the line down stream from
the frozen section. The warmer water above the ice will seep through
the melted film and very quickly melt the rest of the ice. The water will
start to flow in about 10 minutes if the connections are properly made.
Since copper pipe will not heat as fast as steel pipe, allow about a 30
percent longer thawing time. (See chart on page 7.)

*High/Low Switch is only on the Hot-Shot 400.
The Hot-Shot 300 puts out 300 amps, yet pulls only 10 amps. It
can clear 1/2” to 1-1/2” pipes up to 100 ft. long.
The Hot-Shot 320 puts out 320 amps, yet pulls only 13 amps. It
can clear 1/2” to 1-1/2” pipes up to 100 ft. long.
The Hot-Shot 400 can clear 1/2” to 1-1/2” pipes up to 175 ft. long.
The Hot-Shot 400 features a “High/Low” switch to allow the unit to
be used on either a 15 amp or a 20 amp outlet. When the High/
Low switch is in the Low position, the unit will draw 14 amps and
supply 320 amps of thawing power. When in the High position, it
will draw up to 20 amps and supply 400 amps of thawing power.
Both units have a built-in thermal protector. If the internal tempera-
ture reaches a critical level, the Hot-Shot will automatically shut
down.
