these instructions could damage the product or cause a hazardous condition.
2. Check the ratings on the fan label to assure the product is suitable for your application.

50/60 Hz, single phase input power. Catalog numbers TFP42UL12, TFP62UL12, and

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.
These fan packages are not designed for use in hazardous locations.
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.
