Maintenance
ATTENTION! When the system is serviced, the main power switch must always be switched off.
6.1 Rinsing hose.
ATTENTION! The rinsing hose should be checked for any damage or week point before taking it into use
every day. A damaged hose can potential be dangerous.
Do not drive across the hose. Be careful not to damage the hose on any sharp edged or corners.
After use, clean the outside of the hose. Store it on a hose hanger.
For security reasons it is recommended to change the hose at least once every 12 month.
6.2 Nozzles.
Nozzles are warned over time. And warned out nozzle is less effective. It can result in less rinsing power,
higher water usage, higher chemical consumption. Check the nozzles on a regular basis. 1 to 2 times every
month is recommended. Change the nozzle if they are damaged. To be sure you will get the optimized result
we recommend using FOAMICO nozzles.
6.3 Low pressure valves / guns
They must be checked regular. The nut on the handle has to tighten regularly. Check couplings, swivels,
handles for any damaged. A damaged part must be changed for security reasons.
6.4 Couplings.
Couplings should be cleaned and greased on a regularly basis. Use only approved grease. This will extend
the live time of couplings. Always make sure there is a nozzle or lance mounted in the coupling before
opening. Rinsing through an open coupling can damage the O-rings.
6.5 Ball valves.
Every ball valve on the inlet for water inlet for air outlet for water/foam and outlet for sanitizer must be
adjusted.
First time, after one week, and then, once every month. Tight the nut on the handle to avoid leakage.
6.6 Non-return valves
ATTENTION! Non-return valves are very important to secure a correct function of the system.
Non return valves for air: The system has 2 non- return valves for air. The purpose of these is to prevent
water running back into the air system. Due to the potential risk, the air system for the cleaning system must
be separate from other air systems.
ATTENTION! Never leave the valve for air open. Always secure it is closed when not foaming!
If leakage of water is observed anywhere in the airline, both non-return valves must be changed.
- Non-return valve for chemical: The system has one for each chemical intake. The purpose is to prevent
water running back into to chemicals. It will dilute the chemical and result in none or bad foam quality and to
low concentration
ATTENTION! Non- return valves should be checked once every week. It is recommended to change every
1-2 year
Use only Original FOAMICO non-return valves.
6.7 Suction filter / chemical hose.
The suction filter for chemical should be clean once every week. It is recommended to change filter and
chemical inlet hose every year.
