Lock out the power source before the installation of all accessories.
Fan electrical power can now be applied and special attention should be given to determine if motor is working
properly. At this time, with air system in full operation, with guards attached, it is well for the electrician to measure
the operating amperage of the motor and compare with the nameplate rating to determine that the motor is operating
under safe load conditions.
The fan should not need balancing, as it was balanced at the factory to meet stringent vibration levels before
shipment. However, there are several things that may cause vibration, such as rough handling in shipment and
erection, weak foundations, and alignments.
MAINTENANCE:
1. Before performing any maintenance on the fan, be sure power is turned off and
locked in the OFF position at
the service entrance before servicing the fan.
2. Ventilators should be carefully checked at least once a year. For critical or rugged applications, a routine
check every two or three months is suggested.
3. All motors supplied with Soler & Palau USA ventilators carry a one (1) year warranty from date of shipment.
For repairs within the warranty period, the motor must be taken to the motor manufacturer’s authorized
service dealer. Contact your representative for additional warranty details.
4. A periodic motor check should consist of spinning the motor shaft with the power off to be sure the motor turns
freely.
5. Check sheave set screws to ensure tightness. Proper keys must be in keyways.
6. Do not readjust blade pitch or fan RPM. If sheaves are replaces, use only sheaves of identical size and type.
7. During the first few months of operation, it is recommended that the setscrews be checked to assure they are
tight.
8. The rotating wheel or propeller requires particular attention in most applications since materials in the air
being handled can build up on the blades to cause destructive vibration; and may also corrode and/or erode
the blade metal to weaken the structure of the propeller. Regular inspection and corrective action at intervals
determined by the severity of each application are essential to good service life.
MOTORS:
The fundamental principle of electrical maintenance is
KEEP THE MOTOR CLEAN AND DRY
. This requires periodic
inspection of the motor. The frequency depends upon type of motor and the service.
We recommend periodic checks of voltage, frequency, and current of a motor while in operation. Such checks assure
the correctness of frequency and voltage applied to the motor, and yield an indication of the fan load. Comparison
of this data with previous data will give an indication of the fan performance. Any serious deviations should be
investigated and corrected.
Lubricate integral horsepower motors per the motor manufacturer’s recommendations. Lubrication frequency depends
on the motor horsepower, speed, and service. Use compatible greases.
