Page 9: Water Care
S3000E XES3000E WATER CARE About water care In all cooling equipment, operating in evaporative mode, the cooling is accomplished by evaporating a small portion of the re-circulating water as it flows through the equipment. When this water evaporates, the impurities originally present in the water remain. - Page 10 ® Baltibond Hybrid Coating and SST304L 6.5 to 9.2 Total hardness (as CaCO 50 to 750 mg/l Total alkalinity (as CaCO 600 mg/l max.

Page 12: Chemical Treatment
Certain products used for water treatment, particular some dispersant and bio-dispersant additives, might change the properties of the water (such as the surface tension), which can cause excessive drift loss (water passing through the eliminators). In such case we recommend to review the water treatment (product type, dosage) with your water treatment expert. -
Page 13: Cold Weather Operations
S3000E XES3000E COLD WEATHER OPERATIONS About cold weather operation BAC cooling equipment can be operated in sub freezing ambient conditions provided the proper measures are taken. Listed below are general guidelines which should be followed to minimize the possibility of coil freeze-up. - Page 14 When the equipment is operated with a variable fan speed control device, steps must be taken to avoid both operating at or near to the fan's «critical speed» and below a minimum of 15 Hz for a belt driven unit (or direct driven fans) or 20 Hz for a unit with gear box.

Page 15: Maintenance Procedures
S3000E XES3000E MAINTENANCE PROCEDURES Checks and adjustments COLD WATER BASIN AND BASIN STRAINERS The cold water basin should be inspected regularly. Any debris which may have accumulated in the basin or on the strainers should be removed. Quarterly, or more often if necessary, the entire cold water basin should be drained, cleaned and flushed with fresh water to remove the silt and sediment which normally collects in the basin and under the wet deck surface during operation. - Page 16 HOT WATER BASINS The system water enters the cooling tower through the hot water basin(s). (See figure below). At design flow, the operating level should not be less than 50 mm or greater than 125 mm deep. Quarterly, or more often as required, remove any dirt or debris which may clog the nozzles.
- Page 17 Model number Height of water in the cold water basin (mm) S3E/XES3E-8518-05x to S3E/XES3E-1222-07x S3E/XES3E-1222-10x to S3E/XES3E-1424-14x Cold water basin operating heights The "x" represents the variable numbers or characters in the model numbers. The operating water level in the cold water basin will vary somewhat with system thermal load (evaporation rate), the bleed rate employed and the make-up water supply pressure.
- Page 18 To check the operating level, proceed as follows: 1. Measure height from sump bottom to water level and compare with face value from table. 2. Check valve for leakage and replace valve, if necessary. 3. Check that float arm can move freely and that float ball floats and closes valve. 4.
- Page 19 • Initial Start-up: If the equipment was supplied in assembled major sections the drive has been tensioned and aligned at the factory. Also in this case it is recommended to always check drive alignment and belt tensioning. If equipment was supplied completely knocked-down (KD) then check drive alignment & belt tensioning as per procedures outlined below.

- Page 21 Drive Alignment Proper drive alignment ensures maximum belt life. Alignment is checked for standard drives after correct belt tensioning by placing a straight-edge across both sheaves as shown in the figure below. Sheave alignment standard drives 1. Motor sheave 2. Fan sheave 3.
- Page 22 Single reduction gear drive 1. Lubrication fitting Gear drive units with internally mounted motors are properly installed and aligned at the factory. All fasteners are factory tightened, but should be checked after installation. For unit supplied with externally mounted motors, install and align the motor and drive shaft in accordance with the Assembly Instructions included with the unit.

Page 23: Inspections And Corrective Actions
At start-up, the variable frequency drive should be increased through the range from 0 RPM to maximum motor speed. As the speed is increased, the gear drive system should be observed to note the onset of any unusual rumbling or grinding at specific speeds. These resonant speeds (+/- 10%) should be "locked out" by the variable speed drive. - Page 24 • accumulation of dirt and debris • presence of biofilms Smaller damages of the corrosion protection MUST be repaired as soon as possible to prevent the damage from ® getting bigger. For Baltibond hybrid coating use kit (part number RK1057). Larger damages should be reported to the local BAC Balticare representative.

- Page 26 7. Make sure the profile of the combined inlet shields keeps the water inside the unit. The correct position is with the horizontal part towards the outside of the unit and the sloping part facing downwards to the inside of the unit.
- Page 27 • Excessive vibration • Deterioration of fan assembly Correct or adjust if necessary. Before any disassembly, fan blades and hub should be match marked to ensure proper blade pitch angle when reassembled. CAUTION No service work should be performed on or near the fans, motors, and drives or inside the unit without first ensuring the fan and pump motors have been isolated, tagged and locked in the off position.

Page 28: Lubrication
ELECTRIC WATER LEVEL CONTROL PACKAGE (OPTIONAL) The electric water level control package (optional) maintains a constant water level in the cold water sump independent of cooling load changes and water supply pressure variations. Ensure every six months that all components (valve, float switches) are operational and clean. During commissioning the unit should be filled manually till overflow level (push float ball under) to prevent air suction of the pump during first start-up. - Page 29 MOTOR BEARINGS External motors with frame size >200L (>30kW) have grease fittings grease intervals: twice a year unless otherwise shown on the nameplate of the motor grease products: see below The bearings should be lubricated only with a hand grease gun. Do not use high pressure grease guns, since they may rupture the bearing seals.

Gear drive system LUBRICATION Use only rust and oxidation inhibited gear oils in accordance with AGMA (American Gear Manufacturer's Association), Standard 9005-D94. For general operating conditions, AGMA lubricant number and corresponding ISO Grade should be as shown in the following tables: "Recommended Mineral Oils" and "Recommended Synthetic Lubricants"... - Page 31 Ambient temperature at gear drive -29°C to 66°C AGMA Lubricant Number ISO Grade Manufacturer Oil type* Chevron Oil Co.

Page 32: Cleaning Procedures
Normal operating oil capacity Daily visual inspections and observation for oil leaks and unusual noises and vibrations are recommended. If any of these occur, the unit should be shut down and the cause found and corrected. Periodic checks should be made to ensure the proper alignment of all system components and that all bolts and external fasteners are tight. - Page 33 Typically disinfection is achieved using a sodium hyper chloride solution to maintain a residual value of 5 - 15 mg/l of free chlorine and circulate this around the system for up to 6 hours. Higher chlorine levels for a shorter period are possible, but require a higher level of corrosion protection than galvanized steel only.
