Installation

4.1 To do before the installation of the product

• Use installation material with fire resistance rating for the installation location.
• Examine the packaging for transportation damage and remove the packaging from the product carefully.
• Examine the product and all components for damage.
• Make sure that the motor effect and the fan performance agrees with the expectations at the installation location.
• Make sure that the information on the name plate and the motor name plate agrees with the operation conditions.
• Install the product in a location where there is space for commissioning, troubleshooting and maintenance.
• Make sure that the installation location is clean and dry, for full safety during electrical work.
• Make sure that the installation surface has sufficient capacity to hold the weight of the product.
• Refer to the airflow direction arrows on the name plate or on the product to install the product in the correct position.
• Make sure that all cable glands are tight against the ca- bles to prevent leaks.

4.2 To Install the product
Note: Make sure that the installation location has space for maintenance.
Note: Install the product so that unwanted vibrations are not transmitted to duct systems or roof beams.
Note: The product must be installed horizontally.
Note: Obey local laws and regulations for installation of the smoke gas fan.

1. Put the supplied insulation carpet on top of the chimney or duct system.
2. Cut a hole in the insulation carpet. Make sure that the hole has the same dimension as the inlet cone of the fan.
3. Install the 4 adjustable steering rods in the holes in the bottom plate of the fan. Use the supplied screws and nuts.
4. Push the fan and steering rods into the chimney. It is not necessary to attach the fan with screws in the chimney, the steering rods keeps the fan in position.
5. Attach the supplied steel wire. The steel wire keeps the product on the roof when it is temporarily lifted away from the chimney during chimney sweeping. The product is not supplied with screws and plug to attach the steel wire.
6. Connect the mains supply to the connection box of the product. Refer to 12.3 Wiring diagrams page 12.
   Note:
   The cable has a steel housing that can discolour over time as it weathers in. The coloring of the steel housing will not decrease the protection of the cable.

Electrical connection

5.1 To do before the electrical connection

• Make sure that the electrical connection agrees with the product specification on the motor name plate.
• Make sure that the environment for electrical connection is clean and dry.
• Make sure that the wiring diagram that is included with the supply of the product agrees with the terminals in the connection box.

5.2 To connect the product to the power supply

• Complete the electrical connection for the motor. Refer tothe motor wiring diagram that is included with the product.
• Make sure that the cross section of the protective earthing is equal to or larger than the cross section of the phase conductor.
• Install a circuit breaker in the permanent electrical installation, with a contact opening of a minimum 3 mm at each pole.
• If a residual current device (RCD) is installed, make sure that it is an all-current sensitive RCD. Consider if the product has a frequency converter, uninterruptible power supply (UPS), or an EC motor. EC motors have a leakage current to earth that is <=3.5 mA.

5.3 Speed controller for AC motors

Note:
The speed controller alternatives are different for different motor types. Make sure that your motor is compatible with the speed controller type before you use it.
The speed can be controlled by voltage reduction using a transformer. It is also possible to control the fan speed with frequency converter if the installed frequency converter has built in all-pole sine filter and shielded cables are not needed.

5.4 To install motor protection for AC motors

• If the product has an built in motor protection, reset by disconnecting the product from power for 60 seconds.
• If the motor has temperature monitors such as thermal contacts (TK) or thermistors lead out into the terminal box, these must always be connected in the control circuit us- ing appropriate motor protection.
• Make sure that an overheated motor cannot start again automatically when it becomes cool.
• Install the motor cables and the temperature monitor apart.
• If the motor does not have temperature monitors, install a motor protection switch.
