Unit Weights
Before rigging any unit, the weight of each section should be verified from the unit certified
drawing. Unit print weights include the final assembled unit with all accessories. Accessory
weights (found on the respective drawing) can be deducted from the total weight.
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 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. The IBC rating is
only certified with standard anchorage locations. Using alternate anchorage locations or
alternate steel supports will void any IBC wind or seismic ratings. Contact your local BAC
Representative for details.
Cold Weather Operation
These products must be protected by mechanical and operational methods against damage
and/or reduced effectiveness whenever a unit is operated in below freezing ambient
conditions. Please refer to the Crossflow Coil Product Operation and Maintenance Manual
on www.BaltimoreAircoil.com, or contact your local BAC Representative for recommended
cold weather operation strategies.
Location
All evaporative cooling equipment must be located to ensure an adequate supply of fresh
air to the unit air intakes. 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
recirculated back to the air intakes.
Each unit should be located and positioned to prevent the introduction of discharge
air into the ventilation system of any building. For detailed recommendations on BAC
equipment layout, see our website at www.BaltimoreAircoil.com or contact your local BAC
Representative.
Warranties
Please refer to the Limitation of Warranties (located in the submittal package) applicable to
and in effect at the time of the sale/purchase of these products.
Unit Operation
Prior to start-up and unit operation, refer to the Crossflow Coil Product Operation &
Maintenance Manual shipped with the unit and also available at www.BaltimoreAircoil.com

ATTENTION:
Before an actual lift
is undertaken, ensure no water,
snow, ice, or debris has collected
in the basin or elsewhere in the
unit. Such accumulations will add
substantially to the equipment’s
lifting weight.
NOTE:
Each unit must be located
and positioned to prevent the
introduction of discharge air
into the ventilation systems of
the building on which the unit is
located and of adjacent buildings.
