•
The transport and storage ambient temperature limits are -20 °C to +40 °C.
•
Protect against impact and shocks. Transport the fan in its original packaging.
•
If the storage time exceeds 1 year, the motor bearings of the fan must be tested by turning the fan rotor by hand before installation. The fan rotor must run smoothly.
•
Dispose of the 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:
T
erminal block (standard version, no part index suffix).
Connect the fan with the terminal block as shown in the electrical wiring diagram, see Fig. 2.
The 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).
Stop delay timer (part index suffix 'T').
Connect the air exhaust fan with the stop delay timer (a stop delay switch) 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 time the air exhaust fan senses the indoor
lights are off or turning the separate on/off switch off to which the fan is connected.
Hygrostat (part name suffix 'H').
Connect the with the air humidity sensor (hygrostat) and timer as shown in the electrical wiring diagram in Fig.3 or Fig.4.
The air humidity sensor operating range is 40% to 90% of relative humidity. This accessory option includes the stop delay timer. The operation of the fan with these
optional accessories will depend on the power supply connection method. If connected as shown in Fig.4, the fan will start automatically when the air humidity level
exceeds the start threshold of the humidity sensor. Next, the fan will stop when the air humidity level is reduced below the stop threshold, plus the stop delay time set
with the stop delay timer.
If connected as shown in Fig.3, the fan can also be started with its standard light sensor or operating the separate on/off switch. When the indoor light is off or the
on/off switch is turned off, the fan will stop after the stop delay time set with the potentiometer if the humidity level in the room is below the level preset on the
potentiometer. The humidity detection system is the master system.
NOTE: When the green diode located in the electronic system is on, it means that the humidity level in the room is higher than the preset on the
potentiometer controlling the humidity level adjustment.
