6 Transport, installation and acceptance

NOTE

The combustion calorimeter is generally commissioned by UNION Instruments

GmbH or correspondingly qualified service technicians.
If it is not commissioned by UNION Instruments GmbH (e.g. internal

transport/resale), a suitable procedure must be agreed upon with UNION

Instruments GmbH

6.1 Transport

WARNING

Tipping over or dropping of the combustion calorimeter from the pallet or load-

carrying means may cause injuries!
Use suitable load-carrying means when unpacking and transporting.
Check slings, if applicable, for adequate load-bearing capacity and sound

condition and fasten them carefully!
Never walk or stand under suspended loads!

NOTE

If strong shocks occur during transport, these may damage the housing.

Therefore, check the transport container for damage before opening!
In case of transport damage that is indicative of improper handling, a damage

assessment by the transport carrier (rail, mail, shipping company etc.) must be

arranged within seven days.
Ensure before starting or restarting transport that all transport securing devices

are attached.
