If the fan is fitted to be mounted on a wall or in the ceiling, vibration secured fixing bolts
suitable for the wall or ceiling material are to be used. The bolts must each stand a
torque force of minimum 800 N.
If the fan is to be used indoors and is not mounted on another Nederman product, it is
to be mounted as near the outlet in the room as possible, in order to give under
pressure in the ductwork.
Electrical installation
Check that the mains voltage is the same as on the fan's sign plate. Then connect the
fan according to the wiring diagram in the fan's junction box. It is re-commended to
supply the fan with a lockable safety switch on the mains connection cable. A motor
over-load protector is always to be included in the electrical installation.
Variable speed drive is not an option with 1-phase fans with standard motors.
1 or 3-phase fans, a frequency converter can be used. (max frequency is the rated
frequency).

Starting Instructions
WARNING! Risk of Personal Injury
The fan must not be used without ductwork connected unless the inlet and outlet are
equipped with approved guard nets.
Ear protectors is to be worn when working near the fan.
Check the cable connections for tightness.
Check the grounding of the electric motor.
Start the fan and check that it operates without any excessive vibration and noise.
On 3-phase fans it is recommended to check that the motor shaft rotates in the right
direction (see rotation arrow on the motor). If the shaft rotates in the wrong direction,
two of the connection cable conductors must be reversed. See Figure6.
Outdoor Use / Draining
Recommended protection. IP 68. See figure 7 Page 5.
If the fan is to be used without any protection outdoors or under other circumstances
where moisture and condensation can be present, it must be verified that the motor
has draining holes. Verify these holes are open and not clogged. In the lowest level in
one of the fan casings, a draining hole must be drilled (approx. 0.2" (5 mm)), see
Figure8. Then treat the hole with an anti-corrosive agent.
If the motor is not provided with draining holes the fan must be protected with a
suitable cover.
