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 TFP41UL12, TFP61UL12,
and TFP101UL12 operate on 115 VAC, 50/60 Hz, single phase input
power. Catalog numbers TFP42UL12, TFP62UL12, and TFP102UL12
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.
