IMPORTANT

Notes concerning alarm systems

Breakdowns, malfunctions or faulty settings may cause substantial damage and financial losses when regulat-

ing and controlling the climate in a livestock house. It is therefore essential to install a separate, independent

alarm system that monitors the house climate concurrently with the climate and production controller. According

to EU-directive No. 98/58/EU, an alarm system must be installed in all mechanically ventilated houses.

We would like to draw your attention to the fact that the product liability clause of general terms and conditions

of sale and delivery specifies that an alarm system must be installed.

3.2 Placement of wall fan

The wall fan must be placed in the livestock house according to the drawing supplied. Contact SKOV A/S if ma-

jor changes are made.

must be made to avoid damage to the wall fan.
