Pre-Operation Inspection; Machine And Work Area Set-Up - RIDGID SuperFreeze SF-2300 Bedienungsanleitung

NOTICE This product is used to freeze ice plugs in
water piping systems. The ability to freeze plugs is
dependant on a wide variety of factors as discussed in
this manual. Depending upon the exact set of circum-
stances, this product may not work in all cases.

Pre-Operation Inspection

WARNING
Before each use, inspect your pipe freezing unit
and correct any problems to reduce the risk of seri-
ous injury from electrical shock and other causes
and prevent unit damage.
1. Make sure that the pipe freezing unit is unplugged and
the ON/OFF switch is in the OFF position.
2. Clean any oil, grease or dirt from all equipment and
controls. This aids inspection and control of the unit.
3. Inspect the pipe freezing units for the following:
• Inspect the cord and plug for damage or modifi-
cation.
• Proper assembly, maintenance and completeness.
• Any broken, worn, missing, misaligned or binding
parts.
• Presence and readability of the warning label.
(See Figures 1 and 2.)
• Any other condition, which may prevent safe and
normal operation.
If any problems are found, do not use the pipe freez-
ing unit until the problems have been repaired.
4. Check the hoses to the freeze heads for cracks, kinks,
breaks or other issues. The hoses can be coiled and
flexed when not frosted. Care must be taken not to
twist or kink hoses. This prevents hose damage.
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 per-
formance issues or damage the unit.
6. With dry hands, plug cord into properly grounded out-
let, Move the switch to 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 units and work area accord-
ing to these procedures to reduce the risk of burns,
electrical shock and other injuries and prevent
machine damage.
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 Freezing
Units are not explosion proof and can cause sparks.
• Clear, level, stable, dry location for all equipment
and operator.
• Properly grounded electrical outlet of the correct
voltage. A three-prong or GFCI outlet may not be
properly grounded. If in doubt, have outlet inspect-
ed by a licensed electrician.
• 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 Freezing
Unit will work.
• Determine the system fluid – the unit will only work on
systems containing water. Know what additives are
in the water. Additives can change liquid freeze tem-
perature and make freezing difficult or impossible.
• Determine the system material and size – the unit
will only work on metallic piping systems. For pipe
and tube material and size see Specifications .
• Determine the system water temperature and air
temperature in the area of the desired plug. If
temperatures exceed
up to 1" (25 mm) sizes – 110°F (43°C)
1 1 / " (32 mm) and 1 1
4
2" (54 mm) and larger sizes – 80°F (27°C)
The water/air must be cooled to below these tem-
peratures for the SuperFreeze unit to be used.
• Determine if there is flow in the system – the pipe
freezing 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.
