WARNING
General safety information
1. Protect the fan power cord (or lead wires) from coming in contact with
sharp objects, hot surfaces, and/or chemicals.
2. If continuous operation of the fan is essential to the safe functioning of
any other equipment, adequate warning devices must be installed to
assure safe operation at all times. Hoffman temperature switch (catalog
number ATEMNO) can be used to activate an alarm or warning light to
indicate high enclosure temperatures. This temperature switch can also
be used to cycle the cooling fans as cooling requirements change.
Wiring
1. All wiring must comply with applicable local codes and ordinances.
2. Connect the two fan leadwires to the proper voltage power source.
3. All fan wires should be strain relieved with tension clips.
Maintenance
1. Always disconnect power supply before inspecting or working on the fan
package.
2. Generally the fan unit requires no maintenance since the bearings are
permanently lubricated and sealed. The fan cannot be field serviced; it
should be replaced if defective.
3. The foam filter inside the fan package should be periodically removed
and washed with soap and warm water to keep it clean.
CAUTION
These fan packages are not designed for use in hazardous locations.
To avoid electric shock and equipment damage,
disconnect any power supplies to the enclosure
before installing the exhaust grille. Do not energize
any circuits before all internal and external
electrical and mechanical clearances are checked
to assure that all assembled equipment functions
safely and properly.
