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.

1 Product description
An LPC (Low Power Consumption) fan is an energy efficient fan
unit consisting of a PM (Permanent Magnet) motor with matching
motor control and optimized fan blade design for LPC and Dynamic
MultiStep systems.
All variants of LPC fans are completed at the factory, so both the
motor and fan blade match the current application.
The fans are designed for mounting in exhaust units and wall exhaustion in livestock houses where the ventila-
tion system operates in the low-pressure range, i.e. in LPV, diffuse livestock houses and Combi-Tunnel live-
stock houses.
The fans bear a CE marking and have a sturdy four-point suspension.

445136 DA 820 LPC 10-3 fan 230V1 50/60Hz TH
The fan is the same as part no. 445126, but includes a thermal cutout.
445139 DA 820 LPC 12-3 fan 230V1 50/60Hz TH
The fan is the same as part no. 445129, but includes a thermal cutout.
The thermal circuit breaker ensures that the motor disconnects if it gets too
hot. For safety reasons, the fan must be connected manually before it can
be activated again.
Fans with thermal circuit breakers are normally only used in places where
this is a legal requirement, e.g. in Sweden.
ErP 2015 approved.

3.2 Positioning of fan in the exhaust unit
The connection box on the fan must face downwards when the fan is used as a wall exhaustion.
Mount the four fan suspensions using 6 x 25 screws in
the marked positions. Be careful not to over-tighten the
screws.
DA- fans must face the fan blades downward.
Position the legs of the fan in the four fan suspension
units.
Fasten all four fan supports using cable ties around the
fan suspension and rubber suspension.
3.3 Safety distance
If the distance from the floor to the fan blade is less than
270cm, mounting a protective mesh in the inlet bell
mouth may be required to meet the statutory require-
ments.
