3 Operation
3.1 Switchin
g
the Weekend-S
y
stem on and off
The operating agents are on the side of the device, above
the cover for the supplies.
You can switch the compressed air for the tank on and off
using the toggle switch of the pressure valve. The
compressed air must only be switched on when BILPRON
shall be injected into the treatment unit.
During the injection of BILPRON the water has to be
stopped with the turning knob of the water stop.
These operating instructions show the supplies in the top
view so that the positions of both switches can be made out
in a better way.
The required positions for switching on and off are identified
by the marks „I“ and „0“ on the cover. In the non-operation
of the Weekend-System all switches have to be at “0” as
shown on the left.
The toggle switch for the compressed air has always to be
set on „0“ after having finished the injection of BILPRON!
The water stop should always be closed in the evening!
3.2 Fillin
g
the tank
When the liquid level in the tank has dropped to „Min.“, the
tank has to be refilled again! The level indicator is at the
side of the casing.
Only fill the tank so that the liquid covers the mark “Max.”!
When refilling the tank, the toggle switch of the pressure
valve has to be on “0”. While opening the tank, you hear a
sibilance. This is normal as the compressed air escapes
from the tank.
Remove spilt BILPRON immediately with a damp cloth.
Only fill the tank so that the liquid does not cover more than
up to the bottom of the filter.
If the fill level is too high, liquid might enter the Weekend-System via the
air-relief valve!

II. Installation instructions
(for qualified technical staff only)
The procedures described below must only be carried out by suitably qualified
technicians for dental devices in accordance with the valid instructions for electrical
safety and the drinking water decree.
Directive 93/42/EEC for medical devices, annex I; paragraph 9.1
If a product is meant for use in combination with other products or equipments, the combination
including the connections must be safe and it must not affect the intended function of the products.
Each restriction of use must be stated on the label or in the operating instructions.

Application of the BIOFILM-REMOVING-SET
The Biofilm-Removing-Set serves for the removal of biofilm in the
water lines of the treatment unit.
An application is required for treatment units which have
been in use for more than one year when the Weekend-
System is installed and must be carried out by a
technician.
The Biofilm-Removing-Set contains step-by-step
instructions which explain its use in detail.
All hand and angle parts, instruments for the removal of
dental tartar, multifunctional syringes and so on must be
removed completely so that the water lines within these
instruments are not blocked due to the cleaning process.
5 ltr. pressure tank system with
connection for tube 6/4
ALPRO article no. 8589
The initial thorough cleaning of the water lines with the
Biofilm-Removing-Set must not be carried out through the
Weekend-System!
For the initial cleaning of the water lines an external
pressure tank system must always be used by means of
which the BRS liquids can be injected into the water lines
of the treatment unit with at least 2 bar.
A garden spray device with pump mechanism and pressure storage
function in which a tube connection instead of a syringe can be
screwed would be ver
y
suitable.
