Unit Weights
Before rigging any BAC equipment, the weight of each section should be verified on the unit certified drawing.
These weights are approximate and should be confirmed by weighing before lifting when available
hoisting capacity provides little margin for safety.
Caution
BEFORE AN ACTUAL LIFT IS UNDERTAKEN, ENSURE NO WATER, SNOW, ICE OR DEBRIS
HAS COLLECTED IN THE SUMP OR ELSEWHEREIN THE UNIT. SUCH ACCUMULATIONS WILL
ADD SUBSTANTIALLY TO THE EQUIPMENT’S LIFTING WEIGHT.
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
The unit must be properly anchored in place.
Refer to the suggested support details on the certified drawing for locations of the mounting holes. Anchor bolts
must be provided by others.
Holes suitable for 20 mm bolts are provided in the bottom flange of the lower section for bolting the unit to the
support beams.
Leveling
The unit must be level for proper operation and ease of piping.
Support beams must also be level as shims should not be used between pan and support beams to level the unit.
Connecting Pipework
All piping external to BAC cooling equipment must be supported separately.

1 General Information
1 General Information

In case the equipment is installed on vibration rails or springs, the piping must contain compensators to eliminate
vibrations carried through the external pipework.
Suction pipe sizing should be done according to good practice, which may for larger flows require larger pipe
diameters than the outlet connection. In such cases adapter pieces need to be installed.
Freeze Protection
These products must be protected against damage and/or reduced effectiveness due to possible freeze-up by
mechanical and operational methods. Please refer to the BAC Product & Application Handbook or contact your
local BAC Balticare representative for recommended protection alternatives.
Bleed Line Installation
On all open cooling towers, install a bleed line with valve between the system circulating pump discharge riser and
a convenient drain. Locate the bleed line in a portion of the riser piping that drains when the pump is off.
The bleed valve should always be open when the unit is in operation, unless the bleed rate is automatically
controlled by a water treatment system.

RIGGING
General Notes
1. Units that ship in multiple sections can be assembled on the ground first before being lifted to their final
position. (see "Single Piece Lift" in the following table).
2. Spreader bars of the full width of the section must be used between the lifting cables to prevent damage to the
section.
3. For extended lifts or where hazards exist, it is recommended to use the lifting devices in conjunction with
safety slings placed under the unit.
4. The proper rigging sequence for units is to lift the lower section into place, apply sealer to the pan where the
upper section will be located (See "Section Assembly""Method for Two-Piece Cells" on page16) and then lift
the upper section into place.
5. Lifting devices have been provided on all sections. The tables below give the preferred method for rigging each
section of a unit.
