Product and Documentation Changes
SKOV A/S reserves the right to change this manual and the product described herein without further notice. In
case of doubt, please contact SKOV A/S.
The date of change appears on the front and back pages.
IMPORTANT: NOTE CONCERNING ALARM SYSTEMS
When regulating and controlling the climate in livestock buildings, breakdowns, malfunctions or faulty settings
may cause substantial damage and financial losses. 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.
Please note that the product liability clause of general terms and conditions of sale and delivery specifies that an
alarm system must be installed.
In case of an operating error or improper use, ventilation systems can result in
production losses or cause loss of lives among animals.
SKOV A/S recommends that ventilation systems be mounted, operated and serviced
only by trained staff and that a separate emergency opening unit and an alarm system
be installed as well as maintained and tested at regular intervals, according to SKOV
A/S’ terms and conditions of sale and delivery.
Rotating fan blade will cut and crush. TURN POWER SUPPLY OFF before removing
cover.
DA 1700 starts automatically –therefore always TURN POWER SUPPLY OFF
before servicing.
Do not operate DA1700 without safety guard.
If DA 1700 outside safety guard is deselected - a safety distance to prevent hazard
zones must be established. The demands in the International Standard for Safety of
Machinery ISO 13857 must be followed.
Safety instruction
Keep the appliance away from children.
The appliance is not intended for use by persons (including children) with reduced
physical, sensory or mental capabilities, or lack of experience and knowledge, unless
they have been given supervision or instruction concerning use of the appliance by a
person responsible for their safety.
Children should be supervised to ensure that they do not play with the appliance.

DA 1700 Wall Fan
1 Product description
The DA 1700 wall fan is a flange-mounted corrosion-free fan with cone and motor-controlled shutter. The fan
is supplied in one version focused on low energy consumption and one version focused on maximizing air
output. Both versions are available in several variants.
DA 1700 is characterised by having a particularly tightly closed motorized shutter, which prevents unwanted
air movement when the fan is not in operation, and a direct-driven motor to reduce motor maintenance.
DA 1700 is designed especially for the demanding house environment both when it comes to climatic and
electrical impacts.

4 Mounting guide
Check that the ordered parts have been received and that they are in undamaged condition before commencing
the installation process. Read the directions carefully before starting mounting.
If the wall fan is installed in areas with risk of load of snow or ice/snow slide, precautions must
be made to avoid damage to the wall fan.
4.1 Placement in the livestock house
DA 1700 wall fans are placed in the livestock house according to the drawing supplied. Contact SKOV A/S in
case of significant deviation.
It is checked that all DA 1700 wall fans can be placed freely in relation to the other equipment, upon agreement
with the owner.
With a hole size of 1525 mm it may be advantageous to increase the distance between laths where DA 1700 is
to be placed, as well perhaps to use a stronger lath on each side of the wall fan, only however upon agreement
with the owner.
