Introduction
1. Before installing cooling fan package, read these instructions carefully.
Failure to follow 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. Catalog numbers TFP41SS, TFP61SS, and
TFP101SS operate on 115 VAC, 50/60 Hz, single phase input power.
Catalog numbers TFP42SS, TFP62SS, and TFP102SS operate on 230
VAC, 50/60Hz, single phase input power.
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.

properly.
