Installation considerations
Accidental damage, poor installation, or site conditions, can give
rise to malfunctions of the control system, and ultimately lead to a
plant breakdown.
Every possible safeguard is incorporated into our products to
prevent this. However, a wrong 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
installer’s responsibility to check the installation thoroughly, and
to fit the necessary safety devices.
Special reference is made to the necessity of signals to the
controller when the compressor is stopped and to the need of
liquid receivers before the compressors. Your local Danfoss agent
will be pleased to assist with further advice, etc.
