Speed control

Verify that this fan is suitable for speed control. On the datasheet and rating
plate the following (combination of) codes can be found:
F = suitable for frequency control / VFD (Variable Frequency Drive)
E = suitable for electronic voltage control (TRIAC / phase cutting)
T = suitable for transformer voltage control
WARNING
If none of these codes is listed, this fan cannot be speed con-
trolled!
Variable Frequency Drive (FC / frequency control)
• Do not reduce the frequency to less than 20% of the nominal frequency
as listed on the rating plate.
• When using a variable frequency drive, the wiring instructions of the vari-
able frequency drive manufacturer must be followed.
WARNING
Do not increase the frequency beyond the nominal value as
listed on the rating plate
Electronic Voltage Control (TRIAC / SOLID-STATE / phase
cutting)
• Do not reduce the voltage to less than 40% of the nominal voltage as
listed on the rating plate.
• Motor noise (humming) can occur due to this type of control
Transformer voltage control
• Do not reduce the voltage to less than 40% of the nominal voltage as
listed on the rating plate.

4.3 UL Installation instructions
WARNING
To reduce the risk of fire, electric shock, or injury to persons,
observe the following:
• Installation work and electrical wiring must be done by qualified per-
son(s) in accordance with all applicable codes and Standards, including
fire-rated construction.
• Sufficient air is needed for proper combustion and exhausting of gases
through the flue (chimney) of fuel burning equipment to prevent back
drafting. Follow the heating equipment manufacturer's guideline and
safety Standards such as those published by the National Fire Protection
Association (NFPA), and the American Society for Heating, Refrigeration
and Air Conditioning Engineers (ASHRAE), and the local code authori-
ties.
• When cutting or drilling into wall or ceiling, do not damage electrical
wiring and other hidden utilities.
• Ducted fans must always be vented to the outdoors.
Hose down
This fan is IP55 and can be hosed down with water. The installer is to use
rigid conduit or electrical metallic tubing with rain-tight fittings, or liquid-tight
flexible metal or non-metallic conduit with acceptable fitting.

Commissioning

1 Impeller rotation direction
2 Airflow direction
Before initial start-up verify that:
1. Installation and electrical connection have been properly completed.
2. No foreign material is present within the fan and fan housing.
3. All necessary safety devices such as guards are in place.
Initial start-up
1. Briefly switch on the power supply and check if the impeller rotates in the
correct direction. Correct if necessary:
– For 3~ fans interchange any 2 of the 3 phases of the supply.
– For 1~ fans contact your supplier.
2. Run the fan and check for quiet (no unusual noises), low vibration opera-
tion. Check that the current draw is within the full load limits as listed on
the rating plate and datasheet.
3. Refer to the troubleshooting section of these instructions if anything
seems out of the ordinary.
