Automatic block

A dedicated deliming program is needed for the fol-
lowing process:
1. Remove the cover from the unit.
2. Place the chemical supply hoses in clean water
and activate the foaming function on all chemical
valves for 1 minute.
3. Place the chemical hoses in deliming fluid and
activate the foaming function for all chemical
valves for 1 minute.
4. Wait 60 minutes.
5. Place the chemical hoses in clean water and ac-
tivate the foaming function on all chemical valves
for 5 minutes.
6. Activated the rinsing function for 1 minute.
7. Test foaming function and make sure the vacuum
is sufficient, it is recommended to be between
14,8-20,7 inHg/-0,05-0,07MPa.

9.7. Coupling

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

9.8. Internal cleaning of the unit

Depending on the environment where the unit is in-
stalled, internal cleaning of the unit might be required.
We recommend opening and cleaning the unit inside
once a year. Do not spray inside the unit.
Chemical hoses; it is recommended to check all
chemical hoses regularly, approx. once every 3rd
month.
