Making pipe connections before plug-
ging in unit prevents arcing between clamp and pipe.
NOTE! Whenever making connections, clean pipe of
paint, scale rust, etc. to ensure good amperage
flow from the clamps to the pipe. Poor connec-
tions will cause the clamps to get much hotter
than normal.
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 insu-
lation 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 ar-
ticles 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 wall of the pipe
melting and flushing the remaining ice out of the
faucet.
1. Make sure unit is unplugged and turned OFF and
cables are completely uncoiled.
