altimore Aircoil Company Series V equipment
has been designed to give long, trouble-free
service when properly installed, operated, and
maintained. To obtain optimum performance and
maximum 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 approxi-
mate frequency for each. Note that the recommen-
dations 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 procedures outlined under the
“Maintenance Procedures” section of this bulletin. The
VT1, VTO, VTL, VF1, VFL, VC1, VC2, and VCL models
are illustrated in a cutaway form on page 2, 3, 4 and 5
with the major points of inspection and service identi-
fied. 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.
