Opening / closing the service opening
Opening
Observe the steps:
First loosen the nuts – do not remove them!
Danger due to pressurized steam! Before opening the revi-
sion cap, ensure that the pressure tank is no longer pressur-
ized. To do so, open the tank cap (1) and remove it.
Reduce the existing pressure if required using the steam out-
let function (see Chap. "Releasing pressure - steam outlet").
Danger due to hot water!
The water in the pressure tank may still be hot.
⇒Open the service ap (12) by applying pressure to the lower edge of the service
ap.
⇒Loosen both fastening nuts at the service cap (13) by two turns each using the
tool provided (17).
⇒Use the tool to turn the service cap approx. 20° to the left and allow water to
drain out through the service ap.
Once the tank is empty:
⇒Remove the fastening nuts.
⇒Turn the service cap to the left until stop and remove it.
Closing
Do NOT lubricate threaded bolts!
⇒Check and clean the sealing in the service cap. Replace if damaged.
⇒Clean the sealing surface of the pressure tank.
⇒Place the service cap into position rotated at approx. 45° and turn it to the right
until stop.
Note the correct position: TOP = up!
⇒Place the fastening nuts into position and turn them by hand until stop.
⇒Tighten the fastening nuts using a tool until they are nger tight.
⇒Wipe out the service ap.
⇒Lift up the service ap and close by pressing the upper corners.
Rinsing the unit

Water quality / rinsing intervals
The unit is only suitable for operation with drinking water. Water that does not comply with drink-
ing water regulations is not permitted as it may contain substances that damage the unit.
The chlorine concentration must not exceed 4 mg/l.
Before startup, determine the water hardness and calculate the resulting rinsing intervals. Test
strips for determining water hardness are part of the scope of delivery.
Weekly rinsing is mandatory if a desalination system is used, regardless of the water hardness
measured.
Water from a softening system results in water with a high pH value in the tank. This can corrode
the tank and may result in total failure of the unit.
When using a desalination system, ensure that no regeneration water with a high concentration of
salt/brine or acid enters the unit.
The following rinsing intervals must be observed depending on the hardness of the water:
Test strips
German degrees (°dH) /
degree of General Hard-
ness (dGH)
< 3 > 4 > 7 > 14 > 21
English degrees
(Clark degrees) (°e) < 3.75 > 5 > 8.75 > 17.5 > 26.25
French degrees

Parts per million
(ppm CaCO3)< 53.4 > 71.2 > 125 > 249 > 374
Rinsing interval 8 weeks 6 weeks 4 weeks 2 weeks Weekly
With the POWER steamer 2, Renfert recommends using the Power steamer
water softener (see online for accessories) to reduce water hardness.
A maintenance plan is available online at www.renfert.com/p918.
Enter the following item number: 18450000 or 18460000 and select
"Downloads".
Water connection - POWER steamer 2
Risk of brackish water owing back into the water supply! To protect drinking water against
non-drinking water, a system separator must be installed between the building water connection
and the steam cleaning unit. The operator is responsible for implementing these measures.
Observe the minimum and maximum connection pressure (see Chap. "Technical data" at the end
of these instructions).
Risk of water damage due to possible loosening of the water hose!
After operation, or when the unit is unattended, turn o󰀨 the water supply at the water shut-o󰀨
valve.
⇒Check that the connections are tted with gaskets.
⇒Connect the angled connection of the water hose (18) to the water connection (16).
⇒Connect the straight connection of the water hose to the water supply with the water shut-o󰀨 valve.
⇒Carefully open the water shut-o󰀨 valve and check the leak-tightness of the connections.

Filling the pressure tank
⇒Unscrew the tank cap (1).
⇒Only ll with the required quantity in accordance with the recommended ll quantity.
Recommended ll quantity, see Chap. "Technical data" at the end of these instructions.
Danger of scalding!
Excess water remains in the funnel-shaped upper housing.
This must be removed before operation.
⇒Wipe o󰀨 / remove excess water in the funnel-shaped upper housing.
⇒Screw in the tank cap and tighten until it is nger tight.
The POWER steamer 1 can be operated using both drinking water and distilled or deionized water.
If the unit is a POWER steamer 2 and if it was connected to the water supply, it lls automatically
after it is switched on.
Electrical connection
⇒Insert the power plug into a building electrical socket.

Operation
Switching on / o󰀨
Switching on:
⇒Switch on the unit by pressing the ON / OFF button (3).
♦The "Heating / Ready for operation" indicator (5) lights up in orange, the unit heats up.
♦ POWER steamer 2: The tank lls automatically.
♦Once the working pressure has been reached, the "Heating / Ready for operation" indicator (5) lights
up in green.
As a result of lling, the thread of the tank cap contains water. This audibly turns to steam during
heating.
How long it takes for the unit to heat up also depends on the mains voltage applied. If the unit is
cold and lled with 3 l of cold water, it could take between 20 and 40 minutes.
Switching o󰀨:
⇒Briey press the ON / OFF button
♦ The heating is switched o󰀨.
♦ All indicators are switched o󰀨.
⇒POWER steamer 2: Turn o󰀨 the water supply.

Observe the following when steam cleaning:
►Always check that the item to be cleaned is suitable for steam cleaning.
►Hold the item in the steam area at least 2 cm away from the nozzle. At frequent intervals, check
the cleaning progress (visual check) as well as any adverse e󰀨ects on the sensitive surfaces of
the item being cleaned.
►The user is responsible for verifying the cleaning result.
Do not dip the handpiece in water!
Danger of scalding due to steam or hot water escaping
Water that has entered the handpiece from outside can become extremely hot or turn to steam.
If steam is used for extended periods, the handpiece and the steam hose can become extremely
hot!
Tank is empty - rell with water
If there is no longer any water in the pressure tank, this is detected.
♦"Tank empty" indicator (4) lights up in red.
♦A short warning signal sounds.
♦ The heating is switched o󰀨.
POWER steamer 1
Danger of scalding due to steam escaping when opening the tank cap and when lling! Only open
the tank cap when there is no longer any pressure.
When lling, do not bend over the ller opening of the pressure tank!
If the tank cap cannot be easily opened, there is still pressure. Do not force open the tank cap.
Release pressure by pressing the steam button.
⇒Release the residual pressure by pressing the steam button or using the steam outlet function (see
Chap. "Releasing pressure - steam outlet").
⇒Do not switch o󰀨 the unit.
⇒Open the tank cap carefully (1) and remove it.
⇒Allow the unit to cool down for at least 45 minutes to prevent hot water spraying out when lling.
⇒Using a container, ll the pressure tank slowly with water through the funnel-shaped upper housing.
Very slowly to begin with!
⇒Wipe o󰀨 / remove excess water in the funnel-shaped upper housing.
⇒Screw in the tank cap and tighten until it is nger tight.
⇒Conrm lling by pressing the ON / OFF button (3).
♦The "Heating / Ready for operation" indicator (5) lights up in orange, the unit heats up.
♦The water is heated using the integrated heating until the working pressure has been reached.
♦Once the working pressure has been reached, the "Heating / Ready for operation" indicator (5) lights
up in green.
The unit only reheats if it has cooled down suciently beforehand. If this is not the case, e.g., be-
cause too little water was relled, the "Heating / Ready for operation" indicator ashes orange and
heating is not yet activated.
Once the temperature has dropped suciently, the heating is automatically switched on and the
"Heating / Ready for operation" indicator lights up permanently in orange.
POWER steamer 2
If the POWER steamer 2 is connected to a water supply that is turned on, the loss of water as a result of
the steam is automatically compensated for.
Releasing pressure - steam outlet
With the steam outlet function, the heating is switched o󰀨 and the pressure released via the handpiece
without the need to keep the steam button held down.
A corresponding description is provided in the operating instructions, which you can download from our
website at www.renfert.com/p918 (see Chap. „Introduction“).

Calcication indicator
The control detects the increasing calcication in the pressure tank. If the calcication exceeds a pre-
dened level, this is signaled as follows:
♦An acoustic signal sounds.
♦ The "Calcication state" indicator (6) ashes.
⇒Rinse/descale the pressure tank at the next opportunity, for example at the end of the week.
How quickly a pressure tank becomes calcied and how this aects the energy eciency of the
heating system depends on a variety of parameters, not all of which can be taken into consider-
ation by the calcication indicator.
For this reason, descaling must be carried out every three months at the latest regardless of the
calcication indicator.
Replacing the handpiece holder
A corresponding description is provided in the operating instructions, which you can download from our
website at www.renfert.com/p918 (see Chap. "Introduction").
