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

®

repair (touch-up) kits

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 (shelf life) 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 and stainless steel coils of BAC closed circuit cooling towers 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.
