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 or on 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 13 mm bolts are provided in the bottom flange of the cooler support structure for bolting the unit
to the support beams.
Leveling
The unit must be level for proper operation and ease of piping.
The unit should be level to 0,5 mm/m over the unit length and width.
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.
In case the equipment is installed on vibration rails or springs, the piping must contain compensators to eliminate
vibrations carried through the external pipework.
The equipment outlet piping must be installed under the operating level of the equipment to prevent air suction and
pump cavitation.
Purge requirements
The installer of BAC closed circuit cooling towers must ensure a proper air purging of the system prior to operation.
Entrained air can restrict the capacity of the cooler, resulting in higher process temperatures.
All connections (installed by others) must be leak free and tested accordingly.
