Unit Operation

Unit Weights 

Before rigging any unit, the weight of each section should be verified 
from the unit submittal drawing. Unit print weights include the final 
assembled tower with all accessories.

Anchoring

Holes suited for M16 bolts are provided 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.

Support beams must also be level. Each footing should be shimmed 
with a firm material to ensure the weight of the tower is carried at all 
points and that the basin ledges are level at all places. Shims may be 
required either side of a joint. This is to be done before the basin is 
filled with water. If vibration isolators are used, a supporting framework 
must be provided between the unit and the vibration isolators to 
provide continuous and rigid support. Anchor bolts, footings and beams 
to be supplied by others.

Cold Weather Operation

These products must be protected by mechanical and operational 
methods against damage and/or reduced effectiveness during sub-
freezing temperatures. Please 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 fans. When units are located 
adjacent to walls or in enclosures, care must be taken to ensure 
that the warm saturated discharge air is not deflected and short-
circuited back to the air intake(s). Also each unit should be located 
and positioned to prevent the introduction of discharge air into the 
ventilation system of the building on which the unit is located & of 
adjacent buildings. For detailed recommendations on layouts, please 
consult your local Baltimore Aircoil 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 RC Series Operation & 
Maintenance Manual shipped with the unit.

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.

WARNING:

 Drawing weights 

are approximate only. They 
should be confirmed by 
weighing, before lifting, when 
available hoisting capacity 
provides little margin for 
safety. Also before lifting 
ensure that no water, ice, snow 
or other debris has collected in 
the unit. Such accumulations 
will add substantially to the 
equipment’s lifting weight.
