Installation and commissioning

Operating conditions

Prior to installation or commissioning of the device, the follow-

ing operating conditions must be observed:

Material reception 

Upon reception of the materials, the components must be care-

fully checked, in order to guarantee that no transport damage

has taken place. Moreover, the dimensions, composition and

number of the identification sticker must be checked as to

whether they are as ordered.

Identification sticker:

To prevent possible damage during transport, the devices will

be delivered ex works on pallets (that correspond to the partic-

ular weight and dimensions) wrapped with tapes and transpar-

ent plastic film. It is recommended leaving this protection in

place until the device is commissioned. The openings of the

pipes should be closed with dust caps to avoid dust and entry of

dirt. 

Transport, lifting and handling

Transport and handling of the unit

shall take place in the position in

which the unit is to be built in later

on, unless expressly stated other-

wise on the unit.

Transport, unloading and lifting of

the unit shall take place with the

necessary care and using tools that

are appropriate for the weight and

dimensions.
