• Open the drain holes in the product.
• Connect the product permanently to the mains supply and activate the built-in standstill heating function.
4.1.5 Installation altitude
The installation altitude is the height above sea level of the installation site.
Products installed up to 1000 m above sea level can be loaded 100 %.
The motors can be installed up to 3500 m above sea level.
Products installed more than 1000 m above sea level must not be fully loaded due to the low density and consequent low cooling
effect of the air.
The motor output power (P2) in relation to the altitude above sea level is shown in the graph.
