9.2. Rinsing the chemical supply/injector system
The chemical supply must always be
rinsed thoroughly after use.
Remains of detergents or disinfectants can clog the
injector so it needs to be rinsed or replaced.
The following procedure will clean the chemistry sup-
ply for detergents and/or remains of disinfectants.
1. Remove User Pack or cans.
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.
9.3. Deliming
• Disconnect the power supply.
• Disconnect the pick up hose from the detergent
non return valve on the injector block.
• Prepare the deliming fluid.
• Connect the deliming fluid to the detergent non
return valve on the injector block.
• Change the unit to the foam function.
• Activate the hose handle until all of the delimning
fluid has been sucked in to the injector block.
• Wait 5 minutes.
• Connect clean water to the detergent non return
valve on the injector block.
• Activate the hose handle until all of the clean wa-
ter has been sucked in to the injector block.
• Remove the temporary pick up hose and reinstall
the original pick up hose.
• Reconnect the power supply.
• 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 month) 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 O-rings should be
replaced.
9.5. Internal cleaning of the unit
We recommend opening and cleaning the unit inside
min. once a month.
