GENERATOR DESCALING
Locate the generator probe (top rear of generator). Remove the low water probe wire (red) and water
level probe wire (grey) from the probe terminals. Isolate probe wires to prevent inadvertent grounding
until required for reconnection. Remove the probe from the top of the generator.
Inspect the generator and probe to determine the severity of mineral scale build-up. If build-up is
considerable, side panel removal may be required. Using a fine grid emory paper remove any scale
build-up on the probe extensions before reinstallation.
Pour the premeasured one pound of descaler into the generator via the probe coupling. Install the probe
in generator and reconnect only the red probe wire.
Energize the electric power supply to unit and push power "ON" switch. The generator is now filling with
water. Open the compartment door and watch the steam port for water flow. When water starts to enter
compartment, reconnect grey generator probe wire. Water should stop flowing.
Turn the heat control switch to "10", setting. Once again view the compartment steam port for water
flow, approximately 3 minutes. Turn the heat control switch to "0" when steam or water starts to gurgle
from port.
Let the solution stand for several hours. The descaling process can range in time from a few hours, to
overnight, depending upon the severity of the scale.
When the descaling process is complete, push the steamer's power switch to the "OFF" position to drain
the generator of descaling solution.
GENERATOR FLUSH
Remove the two probe wires from the probe and isolate them. Remove probe from generator and
examine the generator for any scale residue. Connect the grey probe wire to the "ground" connection on
the top of the generator. Push the power on switch to the "ON" position. Pour the neutralizer solution
into the generator probe coupling. Replace the generator probe and tighten securely, make sure that the
probe terminals .are parallel with the rear wall of the unit. Remove grey wire from ground terminal isolate
wire until required.
Generator is now filling with water and neutralizing solution. Observe the compartment steam port for
water flow, approximately 45 seconds, and reconnect the grey wire to probe terminal. Allow solution to
stand in generator for 5 minutes. Push the power switch to the off position to drain the generator.
Disconnect the grey wire from the probe and isolate it once more. Energize the power on switch and
observe the compartment for water flow. De-energize the power switch when water appears in the
compartment and allow unit to complete the purge cycle. Turn off main electrical supply to unit.
