Safety instructions  

 

Before you install the VMZ, read through this operating manual carefully. If the instructions 
contained within it are not followed, in particular the safety guidelines, this could result in 
danger for people, the environment, and the device and the system it is connected to. 

The VMZ correspond to the state-of-the-art technology. This concerns the accuracy, the op-
erating mode and the safe operation of the device. 
In order to guarantee that the device operates safely, the operator must act competently and 
be conscious of safety issues.  
SIKA provides support for the use of its products either personally or via relevant literature. 
The customer verifies that our product is fit for purpose based on our technical information. 
The customer performs customer- and application-specific tests to ensure that the product 
is suitable for the intended use. With this verification all hazards and risks are transferred to 
our customers; our warranty is not valid. 

Qualified personnel: 

 

The personnel who are charged for the installation, operation and maintenance of the 
VMZ must hold a relevant qualification. This can be based on training or relevant tuition.  
The personnel must be aware of this operating manual and have access to it at all times. 

 

The electrical connection should only be carried out by a fully qualified electrician. 

General safety instructions: 

 

In all work, the existing national regulations for accident prevention and safety in the 
workplace must be complied with. Any internal regulations of the operator must also be 
complied with, even if these are not mentioned in this manual. 

 

Degree of protection according to EN 

60529:

 

Please ensure that the ambient conditions at the site of use does not exceed the require-
ments for the stated protection rating (

 § 9 "Technical data"). 

 

Prevent freezing of the medium in the device with appropriate measures. 

 

Only use the VMZ if it is in perfect condition. Damaged or faulty devices must be checked 
without delay and, if necessary, replaced. 

 

When fitting, connecting and removing use only suitable appropriate tools. 

 

Do not remove or obliterate type plates or other markings on the device, as otherwise the 
warranty is rendered null and void. 

Special safety instructions: 

 

Crystallizing liquids:  
Liquids which crystallize when dried out can cause a malfunction of the VMZ. 

 

Make sure that the VMZ is not run dry. 

 

Prevent the crystallization of the fluid in the device by taking appropriate measures.  

 

Further warnings that are specifically relevant to individual operating procedures or activities 
can be found at the beginning of the relevant sections of this operating manual.
