Page 4: General Information
Shipping BAC equipment is factory assembled to assure uniform quality and minimum field assembly. The adiabatic pre-cooler sections of the TrilliumSeries equipment are shipped separately. Refer to below table for number of adiabatic pre-cooler sections per model. -
Page 5: Unit Weights
The water immersion sensor is shipped loose and stored inside the electrical cabinet for installation on site. Unit Weights Before rigging any BAC equipment, the weight of each section should be verified on the unit certified drawing. These weights are approximate only and should be confirmed by weighing before lifting when available hoisting capacity provides little margin for safety. -
Page 6: Safety Precautions
Since the equipment operates at variable speeds, steps must be taken to avid operating at or near the installation's "critical speed"; For more information consult your local BAC Balticare representative. ELECTRICAL SAFETY Each fan associated with this equipment should be installed with a lockable disconnect switch located within sight of the equipment. No service work should be performed on or near the fans unless motors are electrically isolated. -
Page 7: Warranties
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 QUALIFIED 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. -

DCV-AD RIGGING Unloading of Equipment 1. The equipment arrives on site by truck. It is recommended to unload the unit with a crane. The Adiabatic Pre-Cooling Sections for the TrilliumSeries are crated separately. A forklift should be used for unloading of the crate with Adiabatic Pre-Coolers. A crane must always be used to unload the unit from the truck. -

Each Adiabatic pre-cooler section is equipped with a separate bottom drain guaranteeing full emptying and drying of the gutter system after each adiabatic cycle.

Page 21: Start-Up And Commissioning
BAC Balticare representative for assistance. PURGE REQUIREMENTS The installer of BAC condensers and closed circuit cooling towers must provide a proper system purging, which enables purging air from the coils prior to operation. Entrained air can obstruct free drainage of cooling medium and reduce thermal capacity. -
Page 22: Trilliumseries Condensers - General
TrilliumSeries Condensers - General ADIABATIC PRE-COOLER WATER FLOW A minimum water flow must be distributed over the Adiabatic Pre-Cooler as per Minimum Water Flow Rates. (See table "Minimum Recommended Adiabatic Pre-Cooler Water Flow Rates", section "About Water Care" on page 1) The water flow will depend on the supply water pressure, and can be set by adjusting the adjustment screw on the water flow valve on the flow meter (See Figure below). - Page 23 Control Panel with Variable Frequency Drive The adiabatic pre-cooling will be activated and stopped on the basis of a pre-programmed logical combination of the fan speed and the ambient temperature (release set-point). Default settings will not activate adiabatic pre- cooling unless all fans are running at maximum permissible speed and the dry-to-adiabatic release set-point is reached.
