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.
Special precautions are necessary during periods of inactivity
. When the internal parts are not continually
bathed by the lubricant as during operation, the gear drive is susceptible to corrosion. For best results, let the drive
cool for approximately four hours after shutdown, start the fan and let run for approximately five minutes. This will
coat the internal parts of the drive with cool oil. Thereafter run the fan for five minutes once a week throughout the
shutdown period to maintain the oil film on the internal parts of the gear drive.
On seasonal shut down, it is recommended that the drive unit be completely filled with oil. This can be
accomplished by filling through the air breather port. Cover the drive with a tarpaulin or other protective
covering.
CAUTION
Drain the excess oil before returning the gear drive to service.
By following the above procedures, each BAC gear drive system will provide years of useful service.
Cleaning procedures
MECHANICAL CLEANING
Keeping your evaporative cooling equipment (and the associated system) clean will maintain its efficiency and
help to prevent uncontrolled bacteriological growth. The recommended cleaning procedures are described below:
1. Disconnect fan and pump motor(s) and shut off make-up supply.
2. Remove combined inlet shields, eliminators and drain system. Do not remove sump strainer.
3. Clean debris from exterior and fan(s) with soft brush, if necessary use water and soap.
4. Clean interior with (soap) water and soft brush, if necessary use high pressure water jet.
5. Remove any debris from water distribution system and clean any nozzles if clogged. If necessary nozzle and
grommet may be removed for cleaning.
6. Remove debris from heat transfer section (coil).
7. Flush with clean water and drain to remove accumulated dirt.
8. Remove, clean and replace sump strainer(s).
9. Clean debris from combined inlet shields and eliminators with water jet and install.
10. Remove debris from access doors and panels with soft brush and (soap) water.
11. Close drain and open make-up supply. Fill system up to overflow level with clean water.
DISINFECTION
Disinfection of your cooling system may be needed in case of high concentration of aerobic bacteria and/or
Legionella. Disinfection is also recommended for evaporative cooling systems with known or suspected high
bacteriological levels, prior to a cleaning procedure.
Some local or national guidance also recommends disinfection prior to initial start up, after a prolonged shut down,
after routine cleaning operations or when significant alterations have been made to the cooling system.
Disinfection must be carried out in accordance with a proper procedure and take into account the safety of the
cleaning and disinfection staff.
