WARNING:  In the event of extended lifts or where hazards exist, the lifting devices should be used in conjunction with
safety slings placed under the unit.

Anchoring

Seven-eighths inch (7/8”) diameter holes are provided in the bottom flange of the basin section for
bolting the unit to the support beams.  Refer to the suggested support location drawing included in
the submittal for location and quantity of the mounting holes.  The unit must be level for proper 
operation.  Anchor bolts must be provided by others.  IBC rating is only certified with standard 
anchorage locations.  Using alternate anchorage locations, alternate steel supports or vibration 
isolation rails will void any IBC wind or seismic ratings. 

Safety

Adequate precautions appropriate for the installation and location of these products should be taken
to safeguard the equipment and the premises from damage and the public from possible injury.

WARNING:  When the fan speed of the unit is to be changed from the factory set speed, including the use of a variable
speed 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 BAC Representative on any such applications.

WARNING:  Only personnel qualified to do so should undertake operation, maintenance and repair of this equipment.
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.

Freeze Protection

Cooling towers must be protected by mechanical and operational methods against damage and/or 
reduced effectiveness due to possible freeze-up.  Please refer to the Product and Applications 
Handbook, Operation and Maintenance Manual or contact your local BAC Representative for 
recommended protection alternatives.

Location

All evaporative cooling equipment must be located to ensure an adequate supply of fresh air to the
fans.  When units are located adjacent to walls or in enclosures, care must be taken to ensure the
warm, saturated, discharge air is not deflected and short-circuited back to the air intakes.

CAUTION:  Each unit must be located and positioned to prevent the introduction of discharge air into the ventilation sys-
tems of the building on which the unit is located and of adjacent buildings.  For detailed recommendations on BAC equip-
ment layout, see our website at www.BaltimoreAircoil.com or contact your local Representative. 

Warranties

Please refer to the Limitation of Warranties applicable to and in effect at the time of the sale/purchase
of these products.

Rigging

Refer to Table 1 for the recommended vertical dimension “H” from the lifting device  to the spreader
bar.  In the event of extended lifts or where hazards exist, the lifting devices should be used in con-
junction with safety slings placed under the unit.
