SAFETY PRECAUTIONS:
The operation, maintenance, repair of this equipment should be
undertaken only by qualified personnel. All qualified personnel
should be thoroughly familiar with the equipment, the associated
system and controls, and the procedures set forth in this manual.
Proper care, procedures, and tools must be used in handling, lifting,
installing, operating, maintaining and repairing this equipment to
prevent personal injury and/or property damage.
All electrical, mechanical, and rotating machinery constitute a
potential hazard, particularly for those not familiar with the design,
construction, and operation. Accordingly, adequate safeguards
(including the use of protective enclosures where necessary) should
be taken with this equipment both to safeguard the public (including
minors) from injury and to prevent damage to the equipment, its
associated system, and the premises.
The cooling towers are designed so that access to the top of the
cooling tower is not required to perform routine maintenance. The
top horizontal surface of the tower is not intended for use as a
walking surface or working platform. Service of the CONDUIT™
Distribution System can be accomplished with a portable ladder
from the side or louver face of each cell. If access to the top of the
unit is desired, the purchaser/end-user is cautioned to use appropri-
ate means, complying with applicable safety standards of govern-
mental authorities. At no time should this equipment be operated
without all fan screens, access panels, and access doors in place.
WARRANTIES: Please refer to the Limitation of Warranties applicable to and in effect at the time of sale/purchase of these products.
Freeze Protection: These products must be protected by mechanical and operational methods against damage and/or reduced effectiveness due to
possible freeze-up. Please refer to the Product catalog or contact the local B.A.C. Representative for recommended protection alternatives.

WARNING: When the fan speed of the cooling tower is changed
from the factory set speed, including changes achieved by the use
of a variable fan speed control device, steps must be taken to avoid
operating at or near the fan's "critical speed" which could result in
fan failure and possible injury or damage. Consult with your local
B.A.C. Representative on any such applications.
WARNING: For the protection of authorized service and mainte-
nance personnel, each fan and pump motor associated with this
equipment should be installed with a lockable disconnect switch
located within sight of the cooling tower. No service work should be
performed on or near the fans, motors, and drives or inside the unit
without first ensuring the fan and pump motors have been discon-
nected and locked out.
WARNING: The recirculating water system may contain chemicals
or biological contaminants, including Legionella, which could be
harmful if inhaled or ingested. Accordingly, personnel who may be
exposed directly to the discharge airstream and the associated drift,
mists generated during operation of the water distribution system
and/or fans, or mists produced by high pressure water jets or com-
pressed air (should these be used to clean portions or components
of the recirculating water system), should wear respiratory protec-
tion equipment approved for such use by OSHA and/or local
occupational safety and health authorities.
NOTES:
1. Recommended service
intervals are for typical
installations. Severe
environment conditions
may dictate more
frequent servicing.
2. When operating in
ambient temperatures
below freezing, the
cooling tower should be
inspected more
frequently (see Winter
Operation, page 9).
3. Tension on new belts
must be readjusted
after first 24 hours of
operation and quarterly
thereafter.
