1. Remove User Pack, if any.
2. Hold the rinsing bottle with clean water tightly
against the suction opening (with User Pack) or
against the hose (without User Pack). Alternati-
vely, you can place a User Pack with clean water
in the holder or – without User Pack – place the
hose in a bucket of clean water.
3. Activate the hose handle until clean water comes
out of the nozzle (approx. 30 seconds).
This procedure should be
followed both on the detergent
and the disinfectant side (if this is
installed).
9.3. Deliming
• The interval of the Deliming procedure is depens
the water hardness.
• Make sure the water to the unit is disconnected.
• Remove the Cover from the unit.
• Dismount the injector block. Dismount the air valve
and the non-return valve for air, inclusive of the air
fittings.
• Put the injector block in a deliming bath – make
sure the dosing valve (the knob) is over the sur-
face.
• Wait for 60 minutes.
• Rinse the block in clean water.
• Mount the air valve and the non-return valve on
the injector block and mount the injector block in
the unit.
• Connect water to the unit.
• Test the unit in Foam position make sure the vacu-
um is sufficient, it is recommended to be between
14,8 - 20,7 inHg / -0.05 - 0.07 MPa.
• Test that the unit can start and stop in both foam
and rinse position
• Reinstall the cover on the unit
The following deliming interwals must be observed to
prevent lime building up in the unit, that can discon-
tinue operation of the unit

9.4. Coupling
It is recommended to lubricate all coupling parts regu-
larly (approx. once a week) with waterproof grease
to prevent leaks and damage of packings. If the unit
is equipped with a spray gun the piston of the gun
should also be lubricated.
In leaking quick couplings the packings should be
replaced.
