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)
English degrees
(Clark degrees) (°e)
French degrees
(°fH)

Rinsing interval
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.

Water connection - POWER steamer 2
Risk of brackish water flowing 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 off the water supply at the water shut-off
valve.
⇒ Check that the connections are fitted 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-off valve.
⇒ Carefully open the water shut-off valve and check the leak-tightness of the connections.
When operating with a water supply that uses distilled water, a coffee spoon of salt (table salt), approx.
10 g, must be added to the pressure tank on startup (once only!). To do so, dissolve the salt in a glass of
water and pour into the filler opening.
The salt is only removed when rinsing or descaling the unit.
That is why it must be added every time after rinsing or descaling the unit.
