1. General information
1.1 Introduction
•
These instructions apply to series 4Z flow meters, also
referred to below as fittings.
• Read the instructions completely before using our pro-
ducts to prevent injuries, material damage and mal
-
functions!
• Save the instructions for later reference.
• All rights including copyright and industrial property
rights are explicitly reserved.
1.2 Warnings
•
Warnings are always identified by a signal word. The
following signal words or hazard levels are used:
Danger:
Failure to follow instructions will
lead to serious injuries or death. High risk le-
vel of endangerment.
Warning:
Failure to follow instructions may
lead to serious injuries or death. Moderate
risk level of endangerment.
Caution:
May lead to slight or moderate inju-
ries. Low risk level of endangerment.
Note:
Refers to an instruction that must ab-
solutely be followed.
Information:
Gives useful tips and recom-
mendations..
1.3 Special Hazards
•
It must be ensured that the fitting is resistant for the
media and temperatures that will be used. The resis-
tance of the fitting with aggressive media depends in
individual cases on many variables (such as the tem-
perature, concentration ratio of the medium, material,
environment, tube material etc.). The person ordering
the fitting is responsible for checking for the specific
application. In case of doubt install the fitting on a trial
basis.
• Always comply with the safety data sheets or the safety
requirements for the media you are using!
•
Before removing the fitting it must be ensured that the
-
re is no more medium in the flexible tube/pipe system
and the pressure has completely dissipated. Exercise
caution for toxic, corrosive or hot media residue flowing
out of the line or remaining in dead spaces.
1.4 General Safety Instructions
•
The fitting must be properly connected to the flexible
tube/pipe system.
•
Before installing the fitting make certain that external
mechanical effects such as thrust and bending forces
are not acting on the flexible tube/pipe system.
•
Installation, commissioning, operation, installation,
maintenance, troubleshooting and disassembly must
only be performed by qualified specialists with due con
-
sideration of accident prevention regulations. Person-
nel must be capable based on their technical training
and experience of performing assembly tasks, follo
-
wing technical specifications and recognizing possible
dangers.
•
Personnel with deficient knowledge must be trained
and instructed.
• Areas of responsibility and responsibilities must be pre-
cisely regulated and personnel must be monitored.
These safety instructions do not take into consideration
any:
• Coincidences and events that could occur at the cus-
tomer location during assembly, operation and mainte
-
nance.
•
Local safety requirements, for which the operating
company is responsible to ensure compliance, inclu
-
ding assembly personnel who are used.
1.5 Designated Use
•
The fitting must only be operated within the permitted
usage ranges for pressure and temperature.
• Only the operating media named in the documentation
are permitted to flow through the fitting.
•
The fitting must only be operated if it is in flawless tech
-
nical condition.
•
The fitting must not be operated if it is in partially as
-
sembled condition.
• If other operating modes are not named in the docu-
mentation, they must be approved with the manufac
-
turer.
1.6 Reasonably Foreseeable Misuse
• Any usage other than designated use.
•
Do not make any modifications to the product by your
-
self!
•
Components should only be retrofitted after consulta
-
tion with the manufacturer.
