Maintenance and Cleaning 

DANGER 

Health hazard due to germs 

Wastewater may be contaminated with dangerous germs. 

−

 

Should the measurement system be used in the wastewater area make 
sure to take respective precautions when getting in contact with system, 
transmitter, cables and sensors. 

−

 

Always wear protective clothing. 

 

 

 

WARNING 

Danger by electric voltage 

Prior to beginning maintenance, cleaning and / or repair works (to be executed by 
qualified expert personnel only): 

−

 

disconnect the device from mains power supply or disconnect the re-
chargeable battery 

−

 

Safeguard the higher system from restarting. 

 

 

 

CAUTION 

Damage due to improper maintenance, repairs or cleaning 

Improper maintenance, repairs or cleaning can damage the NivuLink Micro / the 
sensors and cause the device to malfunction. 

−

 

Maintenance, cleaning or repairs should be carried out by qualified techni-
cians only. 

 

 

 

8.1  Installation of spare parts and parts subject to wear and tear 

We herewith particularly emphasise that replacement parts or accessories not 
supplied by NIVUS moreover are not certified and approved by NIVUS too. 
Installation and/or the use of such products hence may negatively influence 
predetermined constructional characteristics of the measurement system or even 
lead to instrument failures. 
NIVUS cannot be held responsible for any damage resulting due to the use of non-
original parts and non-original accessories. 

 

You can find original manufacturer spare parts or accessories in chapter 

9 “Spare parts and accessories”

 and/or in the valid price list 

8.2  Maintenance 

8.2.1 

Maintenance interval 

The NivuLink Micro is conceived to be virtually free of calibration, maintenance and 
wear (requirements of the Industrial Safety Regulations are unaffected). 
NIVUS recommends having the entire measurement system inspected by the NIVUS 
customer service 

once per year

. 

NIVUS recommends to have the measurement system completely be inspected by 
the manufacturer 

after latest

 

ten years

. 

Generally the verification of instruments and sensors is a basic measure in order to 
improve operational reliability and to increase the lifetime.
