altimore Aircoil Company Crossflow Cooling
Towers have been designed to give long, trouble-
free service when properly installed, operated, and
maintained. To obtain optimum performance and maxi-
mum service life, it is important that a program of regular
inspection and maintenance be developed and carried
out. This bulletin is published as a guide to establishing
such a program.
Included in the bulletin are the recommended services for
start-up, operation, and shutdown and the approximate
frequency for each.
Note that the recommendations on
frequency of service are minimums and where operating
conditions are severe, the services should be performed
more often.
For each required service, follow the proce-
dures outlined under the “Maintenance Procedures”
section of this bulletin. The cooling towers are illustrated
on page 2 with the major points of inspection and service
identified. A copy of the unit certified drawing should also
be available for reference. If you need additional informa-
tion about the operation or maintenance of this equip-
ment that is not covered in this bulletin, contact the local
B.A.C. Representative. Their name and telephone number
are on a label at the connection end of the unit.
