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 power 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

NOTICE
The V-FloFan is very susceptible to other airflows that can dis-
rupt a good functioning:
Do not use horizontal airflow fans at the same time as when the
V-FloFan is in operation.
In greenhouses, do not operate the V-FloFan when the window
vents are open.
Infrequent use
If the fan is used less frequently than once per month, run the fan each month
at least 2 hours at full speed to avoid buildup of moisture in the fan motor and
to keep the bearing lubricant in good condition.
DANGER
If the built-in thermal protection is in series with the power sup-
ply and is activated, the fan motor will automatically re-start
after cooling down.
Risk of injury due to unexpected start.
CAUTION
The fan motor can get hot during operation.
Do not touch the fan motor to prevent burns.
