Cleaning And Maintenance Intervals - Renfert POWER steamer 1 Guia De Inicio Rapido

Cleaning and maintenance intervals

The following cleaning and maintenance intervals must be observed:
► Rinsing (see Chap. Rinsing the pressure tank):
- Weekly if using a salt-based softening system
- In all other cases: As specified in the table in the chapter "Water quality / rinsing intervals"
► Descaling (see Chap. Descaling):
- Immediately when signaled by the calcification indicator
- Every 3 months at the latest
► Overpressure valve (see Chap. Checking the overpressure valve)
- Annually
Rinsing the pressure tank
The unit must be rinsed at least in accordance with the intervals determined in Chap. "Water quali-
ty / rinsing intervals".
Danger of scalding due to hot water!
The water in the pressure tank may still be very hot. Be careful when draining the water through
the service opening.
Caution: Danger of chemical burns/corrosion!
The residual water can be strongly alkaline (brine).
Wear protective goggles and protective gloves during rinsing!
Proceed as follows to rinse the pressure tank:
⇒ Release pressure, see Chap. "Releasing pressure - steam outlet".
⇒ Disconnect the unit from the mains power supply.
⇒ Open the tank cap carefully (1) and remove it.
⇒ Allow the unit to cool down.
⇒ Place the unit so that water can flow from the pressure tank through the service opening (12) into a
sink.
⇒ Open the service opening.
⇒ Drain the water completely through the service flap.
⇒ Clean the bottom of the pressure tank as far as possible using the cleaning brush (see scope of deliv-
ery).
⇒ In doing so, fill with water using the tank cap opening and allow it to drain out through the service open-
ing so that loose calcium residue is rinsed out.
⇒ Repeat the procedure until sufficient cleaning has been achieved.
⇒ If residual calcium deposits are still attached inside the pressure tank after cleaning by rinsing and using
a brush (visual check by looking through the service opening; if required shine a flashlight in the tank
cap opening in the pressure tank), descaling is recommended.
⇒ Close the service opening.
Rinsing program - POWER steamer 2 only
In the case of the POWER steamer 2, the integrated pump and the water supply can be used to automate
rinsing.
A corresponding description is provided in the operating instructions, which you can download from our

Descaling
Caution: The descaling solution is corrosive!
Wear protective goggles and protective gloves during descaling!
Remove cleaning liquid residue from work surfaces immediately with a damp cloth and rub dry
with a dry cloth.
Only use the Renfert descaling solution "Renfert POWER steamer descale" for descaling as it
provides corrosion protection for the pressure tank.
Do not use citric acid for descaling. If filling while warm (residual heat or residue when heating),
citrate powder is formed that clogs the pipes and equipment, causing failure of the unit.
Descaling solutions that are not authorized could damage the pressure tank and mechanical com-
ponents, quickly causing complete failure.
The warranty is voided if a descaling solution is used that is not approved.
(see Chap. "Introduction").
