TrilliumSeries™ Adiabatic
Cooler - TRF Rigging & Assembly Instructions

Rigging
Page | 7
The following parts should be inspected (if applicable for the unit’s configuration):
Adiabatic pre-cooler pads
Interior surfaces
Control panel
Sump components
Coil surfaces
Water connection piping
EC fan module(s)
Water distribution system
Exterior surfaces
Fan guard(s)
Leaving fluid temperature sensor
For TrilliumSeries
™
adiabatic coolers that have been shipped charged with nitrogen, verify that the coil maintained pressure of
15 psi (1 bar) by measuring the pressure with a pressure gauge on the Shrader valve prior to installation. The leaving fluid
temperature sensor is shipped loose and stored inside the electrical cabinet for installation on site.
Unit Weights
Before rigging any unit, the weight of each section should be verified with the unit submittal drawing.
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.
NOTICE:
Before an actual lift is undertaken, open the access hatch and check to ensure no
water, snow, ice, or debris has collected in the sump or elsewhere in the unit. Such
accumulations will substantially
add to the equipment’s lifting
weight.
Anchoring
7/8”
diameter holes are provided in the bottom flanges of the unit 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
within 1/16”
per foot in both length and width directions for proper operation.
Supporting steelwork and anchor bolts are
to be designed and furnished by others.
BAC recommends 3/4”
diameter, SAE J429 Grade 5, ASTM A325 Type 1 or
equivalent anchor bolts. Beams should be selected in accordance with accepted structural practices. Supporting steel must be
greater than or equal to the length
of the unit’s base
, and the unit may not be point supported. Each beam should be designed,
as a minimum, for 65% of the total unit operating weight applied as a uniformly distributed load. If vibration isolators are to be
used, the units shall be installed on steel support first and the vibration isolators (provided by others) should be mounted under
the steel support. Refer to the vibration isolator
manufacturer’s guidelines before loading/unloading weight
from the unit. When
a unit is anchored directly to concrete on grade without steel supports, the support concrete must be flush and level at top.
Concrete for unit support and anchors are to be designed and furnished by others in accordance with accepted structural
practices. When units are anchored by anchor rods,
3/4”
diameter ASTM F1554 Gr. 105 anchor rods or equivalent are
generally recommended.
WARNING:
To prevent severe injury, death and/or property damage
the unit must be properly
anchored before operation begins.
