COMMISSIONING
Flushing
Pipes etc. must be flushed efficiently before connecting the unit.
Before commencing operation on the unit or following repair work, the unit must be flushed thoroughly to remove any
impurities or foreign bodies.
Bleeding
Prior to starting the system for the first time and following any interruption of the water supply, the pump and
pipelines must be bled thoroughly to avoid damage to the pump’s shaft seal.
Air pockets in the pipes may cause destructive water hammer when the pump starts.
Disinfection
Local specifications may require disinfection of the wetted parts like internals of pipes and pumps before use to avoid
contamination of newly cleaned surfaces.
Dosing (MS5 and MS7)
Adjust the dosing according to the chemical supplier’s recommendations.
Always calibrate and, if required, document the dosing on a regular basis.
Air (MS5 and MS7)
Adjust the air pressure until a satisfactory foam quality is achieved.
Note that good foam quality depends on the mixture of water, chemical and air and getting a perfect result requires
some adjustments of the mixing ratios.
OPERATION
Safety
It is recommended that suitable working clothes be worn. For protection against certain types of detergents, always
use protective goggles, respiratory protective equipment and rubber gloves.
It is recommended that non-slip footwear be worn since the floor can be slippery due to the presence of water and
foam.
This system may only be operated, maintained and – not least - repaired by persons who are familiar with the system
and properly trained to carry out the job concerned.
It is the customer’s responsibility that these installation and operating instructions are supplemented by in-house
instructions concerning inspection and reporting, industrial management, personnel training, etc.
Do not carry out any work if you are unsure of the consequences or are insufficiently skilled to carry it out. If in doubt,
you should contact your superior or your agent in advance.
Never direct the water jet at other persons.
Never direct the water jet at electrical installations.
Check that couplings “lock” when hoses and nozzles are fitted. If possible, practise this procedure before operation.
Always relieve the pressure in the rinsing hose by opening the low-pressure gun or valve after the water supply has
been shut off before dismantling the couplings and removing the hose.
During operation of the system, ensure that the low-pressure gun/valve is closed before releasing the handle.
When the low-pressure gun or valve is opened, the water jet will result in a certain amount of counter-pressure.
Therefore make sure that you hold the handle firmly and have a firm foothold.
Before removing the cabinet, the power supply must be switched off.
