Installation considerations
Accidental damage, poor installation, or site conditions can give rice to malfunctions of the control system, and
lead to a plant breakdown. Every possible safeguard is incorporated into our products to prevent this. However, an
incorrect installation, for example, could still present problems. Electronic controls are no substitute for normal,
good engineering practice. Danfoss will not be responsible for any goods, or plant components, damaged as a result
of the above defects. It is the installers responsibility to check the installation thoroughly, and to fit the necessary
safety devices. Particular attention is drawn to the need for a "force closing" signal to controllers in the event of
compressor stoppage and to the signal requirement for suction line accumulators.
Your local Danfoss agent will be pleased to assist with further advice, etc.
