Installation
It is essential to observe the following instructions step by step to ensure
safe start-up. Start-up may only be conducted by trained specialists.
The standard pump is not suitable for installation in explosion hazard ATEX
areas. Please contact us, if you are planning such an application. Before
installing the pump you must reliably disconnect it from the electrical power
supply and prevent the pump form running up inadvertently.
Observe all safety regulations.
3.1 Setting up
The pump must be set up or mounted horizontally on a flat surface. Special
mounting is not required.
The pump must be levelled within a tolerance of ± 2 degrees.
The following ambient operating environment must be observed:
■
Pollution degree 2
■
Ambient temperature: 18 °C to 40 °C (54 °F to 104 °F),
■
Ambient pressure = Atmospheric pressure.
■
Rel. humidity ≤ 95 % without condensation
In order to avoid over-heating of the pump, an undisturbed fresh airflow to
the pump is necessary.
Consider changes in ambient temperatures that might occur when air condi-
tioning is turned down, such as nights and weekends.
The pump must be kept clean (no dust deposit).
The usual transient over-voltage level corresponds to the category II of the
impulse withstand (over-voltage) of the IEC 60364-4-443.
