Cleaning / Maintenance - Renfert POWER steamer 1 Schnellstartanleitung

If steam is used for extended periods, the handpiece and the steam hose can become extremely
hot!
en
The unit's steam outlet function remains active until it is switched off by pressing the steam but-
ton or the ON / OFF button.
Switching off the steam outlet function:
Wait until the pressure has been fully released before switching off the steam outlet function.
⇒ Briefly press the steam button or the ON / OFF button.
♦ The solenoid valve is closed.
♦ The unit is OFF.
⇒ Open the tank cap.
⇒ Allow the unit to cool down before further cleaning or maintenance work.
Once the steam outlet function has been switched off, open the tank cap to prevent pressure
building again in the pressure tank due to residual heat.
Calcification indicator
In the case of continuous operation with drinking water, dirt collects in the pressure tank as well as cal-
cium deposits as a result of the hardness of the water. These either form as a crust on the walls of the
pressure tank or pieces of crust break off and settle at the bottom of the tank.
This reduces the energy efficiency of the heating.
The control detects the increasing calcification in the pressure tank. If the calcification exceeds a pre-
defined level, this is signaled as follows:
♦ An acoustic signal sounds.
♦ The "Calcification state" indicator (6) flashes.
⇒ Rinse/descale the pressure tank at the next opportunity, for example at the end of the week (see Chap.
"Rinsing the pressure tank" and "Descaling").
The calcification level is not saved. Instead, it is determined again every time the unit is switched on and
heated up.
How quickly a pressure tank becomes calcified and how this affects the energy efficiency of the
heating system depends on a variety of parameters, not all of which can be taken into consider-
ation by the calcification indicator.
For this reason, descaling must be carried out every three months at the latest regardless of the
calcification indicator.
Replacing the handpiece holder
The handpiece holder (9) is mounted on the right side of the housing on delivery.
It can be mounted to the left side of the housing if required.
A corresponding description is provided in the operating instructions, which you can download from our

Cleaning / Maintenance

The unit does not contain any internal parts that require maintenance.
Opening the unit is not permitted other than as described below!
Danger of burns!
Only carry out cleaning and maintenance work if the unit has cooled down and has been depres-
surized!
In the case of cleaning/maintenance work while the service cap is open (13), always place the unit
so that water that flows out is collected. For example, place next to a sink.
Cleaning
Do not steam clean the unit under any circumstances.
To clean the unit, only wipe the outside with a damp cloth.
Do not use any solvent-based or abrasive cleaning agents.
