For convenience sediment removal and lime scale removal should be performed at the same time LIME SCALE REMOVAL The amount of calcium carbonate lime released from water is in direct proportion to water temperature and usage The higher the water temperature or water usage the more lime deposits are dropped out of the water This is the lime scale which forms in pipes heaters and on cooking utensils Lime accumulation not only reduces the life of the equipment but also reduces efficiency of the heater and increases fuel consumption The usage of water softening equipment greatly reduces the hardness of the water However this equipment does not always remove all of the hardness lime For this reason it is recommended that a regular schedule for deliming be maintained The depth of lime buildup should be measured periodically Heaters will have about 3 7 6cm of lime buildup when the level of lime has reached the bottom of the cleanout opening or about 1 2 5cm of lime buildup if it has reached the drain valve opening A schedule for deliming should be set up based on the amount of time it would take for a 1 2 5cm buildup of lime Example 1 Initial inspection shows 1 2 1 3cm of lime accumulation Therefore the heater can be delimed once a year Example 2 Initial inspection shows 2 5cm of lime accumulation Therefore the heater should be delimed every 3 months Sediment and lime scale removal may be accomplish
