8. Operation

8.1. Before Operation

Make sure that the carrying capacity of the wall is
sufficient before mounting the unit to the wall, use ap-
propriate screws and dowels when mounting the unit.
The pipeline must be rinsed through
before the system is connected.
Remove cover before the unit is mount-
ed on the wall.

8.2. Start/Stop (change, rinse, foam, des)

Start the unit
1. Check that the power supply is conneted and the
water supply for the system is open.
2. Select requested function. Use the unit according
to the "User Guide".
Stop the unit
3. Disconnect the power supply
4. Close the water supply
It is important to close the water when
the unit is left after use .
• If the water supply is left open when the unit is not
in use, water might seep int othe product pick up
line if the non-return valve on the injector block is
leaking.
Water seeping back in to the product pick up line will
dilute the product in the can and this will effect the
foam quality when foaming with the unit.
CAUTION
The chemical supply must always be
rinsed thoroughly after use
5. The following procedure will clean the chemical
supply for detergents and/or remains of disinfect-
ants.
6. 1. Remove User Pack or the cans.

against the suction opening (with User Pack).
Alternatively, you can place a User Pack with
clean water in the holder or – without User Pack
