Water Damage Guide
Every year, millions of dollars worth of electrical and electronic equipment is damaged or ruined by the effects of water contamination due to rain, flooding, broken water pipes and fire related damage. CRC Electrical Products and the following procedures are effective tools in recovering water-contaminated equipment, significantly reducing damage and many times leading to the complete recovery of flooded equipment
STEP 1: CLEAN THE EQUIPMENT
To remove dirt, mud, oil, sludge and other contaminants deposited by water, follow these directions as closely as possible:
Remove end bells from electric motors and pumps.
Remove covers from switch gear and control panels.
Flush or spray equipment with generous amounts of clean water and a water based cleaner such as our HydroForce® products to remove any water based contaminants. If possible, dip equipment in a tank or drum of clean water, and agitate while submerged.
Stand motors and pumps on end and allow to drain.
Note: Equipment already soaked with water will not be damaged by the use of clean water to flush away dirt, mud and chemical contaminants. Equipment flushed with clean water responds more quickly to treatment with CRC Products.
STEP 2: APPLY A CRC CLEANER OR DEGREASER
To remove oil, grease and sludge contamination not removed by water flushing, dip equipment in a CRC heavy duty degreaser, such as: CRC Lectra-Clean®, CRC Lectra-Clean® II, Heavy Duty Degreaser or Heavy Duty Degreaser II, or spray thoroughly. Agitate motors and pumps while submerged. Remove and stand on end. Allow to drain. Spray switch gear and control boxes liberally. Be sure to spray all contaminated areas. Allow to air dry. CRC Cleaner or Degreaser
Note: Since CRC heavy duty degreasers are strong cleaners, they may cause crazing or softening of some
plastics. It is recommended that a small area be tested before using on plastic parts.
STEP 3: APPLY A CRC MOISTURE DISPLACING LUBRICANT
Saturate equipment with liberal amounts of CRC 2-26®/3-36®, inside and out. When possible, dip equipment in CRC 2-26®/3-36®. Agitate while submerged. Remove and allow to drain. Spray generously and allow excess to run off. Continue spraying until CRC 2-26®/3-36® run-off is clean and clear. CRC Moisture Displacing Lubricant
Note: CRC 2-26® is amber in color and CRC 3-36® is green/blue in color. When dilluted with water, it becomes milky colored. Allow to drain. Adequate drainage is a must.
STEP 4: MEASURE RESISTANCE
Take Megger readings after equipment has drained. If readings are not up to minimum resistance levels, REPEAT applications. Minimum resistance levels have been set in the IEEE RECOMMENDED PRACTICE FOR TESTING INSULATION RESISTANCE OF ROTATING MACHINERY STD: 43-1974 reaffirmed 1984. It reads as follows:
Rm = kV+1
Where Rm = recommended insulation resistance in megohms at 40° C of the entire machine winding
kV = rated machine terminal to terminal potential in rms kilo volts
Minimum resistance is then 1000 ohms/volt + 1 megohm
STEP 5: APPLY A CRC PRECISION CLEANER
When minimum levels have been reached, spray low voltage contacts with a CRC Precision Cleaner (such as NT™ Precision Cleaner, Contact Cleaner 2000® Precision Cleaner, XT-2000™ Precision Cleaner or QD® Contact Cleaner) to remove any dirt particles before energizing.
STEP 6: DO NOT ENERGIZE UNTIL MINIMUM RESISTANCE LEVELS ARE OBTAINED.
When Megger readings indicate minimum resistance levels have been reached, energize motors and pumps under "no-load" conditions. Allow to run for a period of time to continue drying under normal conditions. When Megger readings return to normal, motors and pumps can be used in normal loaded manner.
Tropical storms and hurricanes not only cause extensive damage to electrical and electronic equipment, but their aftermath is devastating and requires an extensive clean-up effort. Maximum performance from power tools is a must. Don’t forget additional products available from CRC such as: Chain & Wire Rope Lubricant, Belt Dressing, Air Tool Oil, Bar & Chain Lubricant, Universal 2-Cycle Oil and our wide array of greases. Also, remember CRC’s HydroForce® line of products for general purpose cleaning, degreasing and disinfecting.
