9 Handing over the unit to the
operator
Inform the operator about the function, operation and inspection of the
product as per the installation and operating instructions and hand over
all the product documentation to the operator.
10 Operator responsibilities
You have purchased a product that is durable and easy to service.
However, all technical equipment requires regular servicing so that it
continues to function properly.
Check the water quality and the hydraulic conditions in the system on
a regular basis.
To ensure proper functioning and to meet the warranty requirements,
regular inspections must be carried out by the operator (every 2 months),
and routine maintenance must be performed by the BWT after-sales
service staff or an installer authorised to carry out maintenance by BWT
(every 6 months).
The replacement of wearing parts within the prescribed maintenance
intervals is also required for the warranty and proper functioning of the
unit.
The operator is responsible for checking that the drinking water tank and
other components are in good working order, and in particular for the
hygiene of the drinking water from the tank and the circulation water.
BWT explicitly instructs customers to comply with the legal requirements
and technical regulations.
The operator must perform the following checks regularly to ensure that
the product functions properly.
●
Weekly check of air hoses for blockage, deposits or damage. Have
air hoses replaced if necessary. Note the sequence of flow.
●
Once a month or after stoppages, check whether there is water in
the air line on the injector. If there is, unscrew and bleed the line or
replace it with a new line. Check the check valve built into the injector
and clean the valve as necessary (paying special attention to the ball
and pressure spring).
●
The cleaning interval for the emitter casing tube depends on the
water quality of the circulation water. Elevated concentrations of
water hardness (calcium and magnesium), corrosion products (iron,
zinc, etc.), or organic or cloudy substances may increase the amount
of cleaning required.
●
Clean the dirt traps every six months or as needed (see chapter
“10.2 Cleaning the dirt trap”, page 28).
