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 compo-
nents, 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.

regularly saved. This opening degree is used if there is a need for
emergency cooling.
