6. When plugging the Pipe Thawing Tool into the elec-
trical outlet, making sure to position the power cord
along the clear path selected earlier. If the power
cord does not reach the outlet, use an extension cord
in good condition.
To avoid electric shock and electrical
fires, never use an extension cord that is damaged or
does not meet the following requirements:
• The cord has a three-prong plug similar to shown in
Electrical Safety section.
• The cord is rated as “W” or “W-A” if being used out-
doors.
• The cord has sufficient wire thickness (14 AWG below
25′/12 AWG 25′ - 50′). If the wire thickness is too small,
the cord may overheat, melting the cord’s insulation
or causing nearby objects to ignite.
To reduce risk of electrical shock, keep all
electrical connections dry and off the ground. Do not
touch plug with wet hands.
Operating Instructions
WARNING
To reduce risk of electrical shock, keep all electri-
cal connections dry and off the ground. Do not
touch plug with wet hands.
Be very careful when thawing frozen pipes. Clamp
tips and cable connections become hot during use.
Avoid contact with skin as burns can result.
Keep clamps away from combustible materials or
articles that can be damaged by heat.
Do not leave the unit unattended while thawing.
Thawing Tap Water Lines
NOTE! It is recommended that there be standard water
pressure on one side of the frozen section of
pipe and an open faucet on the other side of the
frozen section (Figure 4). As the pipe warms to
above freezing point, the water, with pressure
behind it, will seep along the inside walls melting
and flushing the remaining ice out of the faucet.
1. Make sure unit is unplugged and turned OFF and
cables are completely uncoiled.
2. Place one clamp on each side of the frozen section of
pipe. Open the faucet where no water flows.
Making pipe connections before plug-
ging in unit prevents arcing between clamps and pipe.
3. Plug unit into a grounded 15 amp outlet making sure
to position the power cord along the clear path se-
lected earlier.
4. Move switch to ON (up position on KT-190. Center
switch down to low position, left switch to A on KT-200).
5. If current is below 15 amps on KT-200, switch to B. If
current is still below 15 amps, switch to high position
on center switch and right switch up to C.
6. Continue until 15 amps is reached but not exceeded,
D switch setting is used with long runs.
Thawing time may vary from a few seconds to several
hours depending on length and diameter of pipe being
thawed. If time seems unreasonable, check clamps for
proper placement.
