CAUTION

Do not cover units with PVC eliminators or fill with a plastic tarpaulin. Temperature increase due

to sun radiation could deform the fill or eliminators.

AUTHORIZED PERSONNEL

The operation, maintenance and repair of this equipment should be undertaken only by personnel authorized and

qualified to do so. All such personnel should be thoroughly familiar with the equipment, the associated systems

and controls and the procedures set forth in this and other relevant manuals. Proper care, personal protective

equipment, procedures and tools must be used in handling, lifting, installing, operating, maintaining and repairing

this equipment to prevent personal injury and/or property damage. Personnel must use personal protective

equipment where necessary (gloves, ear plugs, etc...)

MECHANICAL SAFETY

Mechanical safety of the equipment is in accordance with the requirements of the EU machinery directive.

Depending upon site conditions it also may be necessary to install items such as bottom screens, ladders, safety

cages, stairways, access platforms, handrails and toe boards for the safety and convenience of the authorized

service and maintenance personnel.
At no time this equipment should be operated without all fan screens, access panels and access doors in place.
When the equipment is operated with a variable fan speed control device, steps must be taken to avoid operating

at or near to the fan's «critical speed».
For more information consult your local BAC Balticare representative.

ELECTRICAL SAFETY

All electrical components associated with this equipment should be installed with a lockable disconnect switch

located within sight of the equipment.
In the event of multiple components, these can be installed after a single disconnect switch but multiple switches

or a combination thereof are also allowed.
No service work should be performed on or near electrical components unless adequate safety measures are

taken. These include, but are not limited to the following:

Isolate the component electrically

Lock the isolation switch in order to prevent unintentional restart

Measure that no electrical voltage is present anymore

If parts of the installation remain energized, make sure to properly demarcate these in order to avoid confusion

Fan motor terminals and connections may have residual voltage after unit shut-down. Wait five minutes after

disconnecting the voltage at all poles before opening the fan motor terminal box.

LOCATION

All cooling equipment should be located as far away as possible from occupied areas, open windows or air intakes

to buildings.

LOCAL REGULATIONS

Installation and operation of cooling equipment may be subject to local regulations, such as establishment of risk

analysis. Ensure regulatory requirements are consistently met.
