- flammable contaminants, including gas, vapours, mists or particulates which may form explosive mixtures with air.
•
The control system must prevent extremely frequent power cycling.
Transport and storage
•
Keep the air exhaust fans in their original packaging in a dry, sheltered room.
•
The transport and storage ambient temperature limits are -20 °C to +40 °C.
•
Protect against impact and shocks. Transport the air exhaust fan in its original packaging.
•
If the storage time exceeds 1 year, the motor bearings of the air exhaust fan must be tested by turning the fan rotor by hand before installation. The fan rotor must
run smoothly.
•
Dispose of the air exhaust fan at the end of its operating life strictly in accordance with environmental protection and waste management laws.
•
Should it occur, damage caused by improper transport, handling, storage or commissioning will be demonstrated and is not on warranty.
ACCESSORIES
Available optional accessories:
Terminal block (standard version, no part index suffix).
Connect the air exhaust fan with the terminal block as shown in the electrical wiring diagram, see Fig. 2.
The air exhaust fan is started and stopped by a separate on/off switch installed in the power supply line of the building (and not included with the product).
Timer (part index suffix “T”).
Connect the fan with the timer (a switch-off delay) as shown in the electrical wiring diagram, see Fig. 3.
The stop delay time can be set with a potentiometer knob on the electronic module of the stop delay timer. The minimum stop delay time is set at 3 min. with the
potentiometer knob rotated counter-clockwise to stop. Turn the potentiometer knob clockwise to set a longer stop delay time accordingly. The maximum stop delay
time setting is 30 min. The stop delay time is adjusted in infinite increments. The stop delay time is counted down from the moment when the signal at the “SL” terminal
disappears caused by switching off the lighting or the on/off switch to which the appliance is connected. Depending on the setting of the “DELAY” slider on the
controller, the fan will start operating when voltage is detected on the “SL” terminal or after 2 minutes after voltage is detected.
Humidity sensor (part name suffix “H”).
Models equipped with humidity sensor (hygrostat) and timer should be connected according to the connection diagram
in Fig. 3. or Fig. 4.
