Reliable i500 Series - Manual (Page 9)

The boiler must be cleaned periodically and any sediment/mineral buildup removed
from inside the unit; otherwise, it may become clogged. The period between cleanings
depends on the frequency of use and the quality/hardness of the water used. If the
unit is in daily use with regular municipal tap water, we recommend a cleaning every two
weeks to a month.
TO CLEAN THE BOILER UNIT
1. Unplug the unit from the wall.
2. Disconnect the iron (i500), the steam gun (i500B) or the steam nozzle (i500A)
from the boiler unit. (The steam nozzle on the i500A may be left on the unit if
desired. It does not affect the cleaning instructions.)
3. Add a mixture of 1 part white vinegar to 5 parts water and pour inside the boiler
tank to capacity. Let the vinegar solution sit overnight.
4. Pick up the boiler unit and pour approximately half of the solution out of the boiler
tank. Vigorously shake/swirl the remaining solution around the tank to loosen
and pick up any softened sediment that may have accumulated inside. Pour the
remaining solution out of the tank. You may see bits of sediment and mineral come
out at this point.
5. Rinse the tank with clean water until there is no smell of vinegar or any sediment
bits coming from inside the tank. NOTE: Sediment/mineral pieces can be blown
into the solenoid valve or the steam nozzle during operation so it is important that
they are not left in the tank after cleaning.
6. The unit is now ready for use.
