COMPREHENSIVE MAINTENANCE

About Comprehensive Maintenance

In order to ensure maximum efficiency and minimum downtime of your evaporative cooling system, it is
recommended to establish and execute a programme of preventive maintenance. Your local BAC Balticare
representative will assist you in establishing and implementing such programme. The preventive maintenance
programme must not only avoid that excessive downtime occurs under unforeseen and unwanted conditions, it
also ensures that factory authorized replacement parts are used, which are designed to fit and for their purpose
carry the full factory warranty. To order factory authorized parts, contact your local BAC Balticare representative.
Make sure you include the unit serial number when ordering any parts.
To facilitate servicing of the equipment, it is suggested that the following parts be carried on hand:
• Make-up float ball (if applicable)
• Water make-up valve
• Fan shaft bearings
• Spray nozzles and grommets
• Spray distribution branch grommets
• Set of belts
• BALTIPLUS/BALTIBOND
Insist on factory authorised parts to avoid loss of efficiency or an operational risk, which may occur when non
authorised parts are used.

Prolonged Outdoor Stay

Should the unit(s) be stored outside prior to installation and/or start-up for approximately one month or longer, or
stored in severe climates, it is imperative that certain actions be performed by the installing contractor in order to
maintain the unit in "as shipped" condition. These actions include but are not limited to:
• Rotate the fan(s) once per month, at least 10 revolutions.
• Rotate the motor shaft of all motors installed on the unit(s) once per month, at least 10 revolutions. This
includes the pump motor.
• Add desiccants to control panel interiors.
• Wrap motor in non-plastic protective material.
• Keep drains open on the cold water basins.
• Ensure unit(s) is stored on level ground surface.
• Remove and store fan belts and access door gaskets.
• Hot dip galvanized coils of BAC condensers are filled with a low pressure inert gas at the factory before
shipping, to ensure an optimal internal corrosion protection. It is recommended to check the overpressure every
six months (connect a manometer to the valve).
• Purge old bearing grease by new grease at start of storage period and repeat before start-up.
• Protect all black steel components with RUST VETO or equivalent corrosion protective material.
For complete instructions, please contact your local BAC-Balticare Representative.
