Safety Precautions - BAC HXV Operation & Maintenance Manual

Safety Precautions

DANGER
• DANGER: Rotating equipment will cause severe personal injury or death to persons who come in contact. Do not perform any service, maintenance or
inspection on or near the fans, motors, and drives, or inside the unit without first ensuring that the fans and pump motors are disconnected, locked out,
and tagged out.
• DANGER: On installations where there are multiple adjacent cells which may be traversed to gain access to another cell, all fan motors must be
disconnected, locked out and tagged out, including those on adjacent cells, before performing any service on or near the fans and drive systems, and
before traversing adjacent cells. Failure to follow this instruction may result in serious injury or death caused by contact with rotating equipment.
WARNING
• WARNING: The top horizontal surface of the unit is not intended to be used as a walking surface or working platform. If access to the top of the unit
is desired, the purchaser/end-user is cautioned to use appropriate means complying with applicable safety standards related to working on elevated
surfaces. If access to the top of the coil is required, place a piece of plywood at least 1/2 inch thick on top of the coil to protect the surface while
performing the recommended maintenance. When finished, carefully remove the plywood.
• WARNING: Hail guards are not designed to support the weight of a person or to be used as a storage or work surface for any equipment or tools. Use
of these hail guards as walking, working or storage surfaces may result in injury to personnel or damage to equipment. Units with hail guards should
not be covered with a plastic tarpaulin
• WARNING: When the fan speed of the unit is to be changed from the factory set speed, including changes achieved by the use of a variable fan speed
device, steps must be taken to avoid operation at or near the fan's "critical speed" which could result in fan failure and possible personal injury or damage.
• WARNING: The recirculating water system may contain chemicals or biological contaminants, including Legionella, which could be harmful if
inhaled or ingested. Personnel 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 compressed air (if used to clean components of the recirculating
water system), must wear respiratory protection equipment approved for such use by governmental occupational safety and health authorities.
• WARNING: All electrical, mechanical, and rotating machinery are potential hazards, particularly for those not familiar with their design, construction,
and operation. Accordingly, use appropriate lockout procedures. Adequate safeguards (including the use of protective enclosures where necessary)
should be taken with this equipment both to safeguard the public from injury and to prevent damage to the equipment, its associated system, and
the premises.
• WARNING: A lockable disconnect switch should be located within sight of the unit for each fan motor associated with this equipment. Before
performing any type of service or inspection, make certain that all power has been disconnected, and the switch is locked out in the "OFF" position.
• WARNING: Dangerous voltages are present in this equipment. Disconnect the electrical service of the source and follow proper lock out and tag out
procedures to de-energize the circuit before servicing or replacing components.
• WARNING: To prevent possible contamination of the make-up water supply, install a backflow prevention method in accordance with applicable local
and national codes
CAUTION
• CAUTION: The operation, maintenance, and repair of this equipment shall be undertaken only by personnel authorized and qualified to do so. All such
personnel shall be thoroughly familiar with the equipment, the associated system and controls, and the procedures set forth in this manual. Proper
care, personal protective equipment, procedures, and tools must be used in handling, lifting, installing, operating, maintaining, and repairing this
equipment to prevent personal injury and/or property damage.
