missing, mis-aligned or binding parts or any other
condition which may affect the safe and normal op-
eration of the machine. The flexible hoses can be
coiled and flexed when not frosted. Care must be
taken not to force hoses to twist or kink. This prevents
hose damage. Check the hoses to the freeze heads
for cracks, kinks, breaks or other issues. If any of
these conditions are present, do not use the machine
until any problems found have been repaired.
4. Check to make sure that the warning and instruction
labels are present and firmly attached. Do not operate
the Pipe Freeze Unit without the warning label. (See
Figure 2.)
Figure 2 – Warning and Labels
5. Inspect the fan grille and louvers into the condenser
housing to make sure that nothing is blocking the air-
flow. Lack of airflow through the unit can cause
performance issues or damage the unit.
6. Make sure that the ON/OFF switch is set to the OFF
position. With dry hands, plug cord into properly
grounded outlet, Move the ON/OFF switch into the
ON position, Confirm that the compressor motor
starts and that the fan runs. Move the switch to OFF
position and unplug the unit.
Machine and Work Area Set-Up
WARNING
Set up the Pipe Freezing Unit and work area ac-
cording to these procedures to reduce the risk of
burns, electrical shock and other injuries and pre-
vent machine damage.
SuperFreeze™ Pipe Freezing Unit
1. Check work area for:
• Adequate lighting.
• Flammable liquids, vapors or dust that may ignite.
If present, do not work in area until sources have
been identified and corrected. The Pipe Freeze
Unit is not explosion proof and can cause sparks.
• Clear, level, stable, dry place for machine and op-
erator. Do not use the machine while standing in
water.
• Properly grounded electrical outlet. A three-prong or
GFCI outlet may not be properly grounded. If in
doubt, have outlet inspected by a licensed electri-
cian.
• Clear path to electrical outlet that does not contain
any potential sources of damage for the power
cord.
• Clear path for access to the work area.
2. Inspect the system and determine if the Pipe Freeze
Unit will work.
• Determine the system fluid – the Pipe Freeze Unit
will only work on systems containing water. Know
what additives are in the water. Additives can
change liquid freeze temperature and make freez-
ing difficult or impossible.
• Determine the system material and size – the Pipe
Freeze Unit will only work on metallic piping sys-
tems, and can only freeze pipes smaller than 2" and
tubes smaller than 2
• Determine the system temperature – if the sys-
tem temperature is greater than 125°F, the system
will need to be shut off and allowed to cool to less
than 125°F. Removing the piping system insulation
will speed up this cooling.
• Determine if there is flow in the system – the Pipe
Freeze Unit will not work on flowing water. If there
is flow in the section of pipe to be frozen, the flow
needs to be stopped by shutting a valve, turning off
a circulating pump, or other appropriate means.
• Determine the air temperature in the area of the pip-
ing system. The Pipe Freeze Unit cannot be used
in areas where the air temperature exceeds 100°F.
• Determine where the piping system needs to bro-
ken for the work that needs to be done.
• Determine if the piping is filled with water. A plug
cannot be frozen into partly filled pipes.
3. Determine location for freeze plug(s).
• The location must allow access with at least one
freeze head, and if only a single plug is required,
it is preferred that there be enough space for both
freeze heads.
