RC series coil products should be rigged and
assembled as outlined in this bulletin.
These procedures should be thoroughly reviewed prior to the
actual rigging and assembly of the equipment to acquaint all
personnel with procedures to be followed and to ensure that all
necessary equipment will be available beforehand.
If outstanding circumstances require a departure from the
procedures outlined in this manual, contact your local BAC
Representative for guidance.
Be sure to have a copy of the submittal drawings available for reference.
If you do not have a copy of these drawings, or if you need additional
information about this unit, contact your local BAC Representative whose
name and telephone number are on the outside of the cold water basin. The
model number and serial number of the unit are also located in this area.

Introduction
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. The
procedures listed in this manual must be thoroughly reviewed prior to
rigging and assembly. Read all warnings, cautions, and notes detailed
in the margins.
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.
Shipping
BAC RC Series units are factory assembled to ensure uniform quality
with minimum eld assembly. As standard, models ship in two sections
per cell (lower and upper). Optional shipment of three sections per
cell and optional containerized shipments are available. Contact your
local BAC Representative for more information. For the dimensions and
weights of a specic unit or section, refer to the submittal drawings.
Pre-Rigging Checks
When the unit is delivered to the jobsite, it should be checked
thoroughly to ensure all required items have been received and are free
of any shipping damage prior to signing the bill of lading.
The following parts should be inspected:
WARNING: Failure to use
designated lifting points
can result in a dropped load
causing severe injury, death,
and/or property damage.
Lifts must be performed by
qualied riggers following BAC
published Rigging Instructions
and generally accepted
lifting practices. The use of
supplemental safety slings
may also be required if the
lift circumstances warrant
its use, as determined by the
rigging contractor.
WARNING: This equipment has
the potential to be a high risk
hazard! Do not handle, rig,
lift, install, assemble, operate,
maintain or enter this
equipment without assessing
the risks involved. control
measures must be developed
to eliminate or minimise the
potential risks.

Unit Weights
Before rigging any unit, the weight of each section should be veried
from the unit submittal drawing. Unit print weights include the nal
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 rm 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
lled 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 deected 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 conrmed 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.
