Introduction
A.O. Smith Dscale is a very powerful colour-coded descaler. Dscale removes
scale and lime deposits. It prevents the scale that is loosened from sticking to
the walls again, so that the scale disappears when rinsed away.
Scale and lime build-up prevent effective conduction of the heat to the water.
Regular cleaning and descaling extends equipment lifespans, helps the heating
process and saves energy.
The service and maintenance technician determines how often maintenance is
needed. The frequency depends on the extent to which scale has formed.
Scaling increases dramatically as the temperature is adjusted upwards. So pick
the lowest possible temperature setting, but do make sure the heat
requirements are met and observe the minimum return temperature for
preventing legionella.
A.O. Smith Dscale is a concentrated product that is generally diluted 1:1 with
water before use (depending on the amount of scale). The quantity of liquid to
use depends on the volume of the appliance - see
A.O. Smith Dscale is a safe biodegradable descaler made from natural raw
materials, including lactic acid and citric acid. When diluted, the solution may be
disposed of via the sewers.
