4. Good connections are required. Clean all pipes before con-
necting the cables. Remove all material touching or near the
pipe, including insulation, pipe heating tape, etc. Make both pipe
connections before plugging unit into receptacle. Ensure all con-
nections are tight to prevent arcing at the clamps. Loose connec-
tions also get hot and reduce current flow.
5. If a good connection is made, the pipe and cables will vibrate
with a 60 cycle hum that you can feel with your hand. After all
connections are made and the unit is plugged in, switch the cir-
cuit breaker on.
6. Monitor the equipment during pipe thawing operation. Use stan-
dard AC clamp-on Amprobe meter to check heating current.
Current should be between 200 and 400 amps. If the current is
less than 200 amps, a second Hot-Shot can be used to increase
current. (See Thawing Pipes with two Hot-Shots.)
Note: Uncoil the cables. Do not leave any cable coiled up or placed
on steel objects or the heating in the pipe will be reduced.
MONITOR THE PIPE TEMPERATURE. SMALL,
EMPTY PIPES WILL GET HOTTER BEFORE A
LARGER PIPE WILL THAW, AND COULD MELT
THE SOLDER IN THE COPPER FEEDER LINE.
REMOVE ALL MATERIAL TOUCHING OR NEAR
PIPE, INCLUDING INSULATION, PIPE HEATING
TAPE, ETC. BEFORE TURNING ON MACHINE AS
THEY CAN BECOME A FIRE HAZARD!
OPERATION
1. Isolate the frozen section of pipe. Inside a house, this is done by
opening faucets and back tracking the pipes. The frozen section
will usually be in the outside walls, near doors, windows, and in
crawl spaces under floors. If all the water outlets in the house fail
to operate, the line from the curb valve to the house is frozen.
2. House service pipes usually have to be thawed by connecting
one cable to the exposed pipe in the kitchen or basement, and
the other cable to the curb service. At the curb, make the con-
nection to the valve at the bottom of the service riser, using the
curb key. Do not connect the cable to the adjustable ground level
cover, as it is a poor connection to the valve.
3. Connect the cables on either side of the frozen section so that
they complete an electric circuit. The cable clamps must be at
least 15 ft. apart. Keep clamps away from combustible materials
or articles that can be damaged by heat. Cables and clamp tips
become hot during use.
MAKE SURE MACHINE IS DISCONNECTED FROM
POWER SOURCE BEFORE CONNECTING CABLES!
CLAMPS AND CABLES GET HOT! KEEP CABLES
CLEAR OF COMBUSTIBLE MATERIALS OR ARTICLES
THAT CAN BE DAMAGED BY HEAT.

All grounds (i.e. electric service, telephone, and cable TV grounds)
must be disconnected, both at the house being thawed and all houses
on the same distribution transformer. There is a possibility that the
output current of the unit may be transferred into the electrical service,
either at the house being thawed, or at a remote location.
THAWING A HOUSE SERVICE PIPE
1. Connect one cable to the exposed pipe in the kitchen or base-
ment.
2. Connect the other cable to the curb service at the valve at the
bottom of the service riser using a Curb Key.
Note: Make sure the Curb Key is clean and makes a tight connec-
tion to the pipe, otherwise the only result will be to heat the Curb
Key.
