In case the equipment is installed on vibration rails or springs, the piping must contain compensators to eliminate

vibrations carried through the external pipework.
The equipment outlet piping must be installed under the operating level of the equipment to prevent air suction and

pump cavitation.
Suction pipe sizing should be done according to good practice, which may for larger flows require larger pipe

diameters than the outlet connection. In such cases adapter pieces need to be installed.

Safety precautions

All electrical, mechanical and rotating machinery constitutes a potential hazard, particularly for those not familiar

with its design, construction and operation. Accordingly, adequate safeguards (including use of protective

enclosures where necessary) should be taken with this equipment both to safeguard the public (including minors)

from injury and to prevent damage to the equipment, its associated system and the premises.
If there is doubt about safe and proper rigging, installation, operation or maintenance procedures, contact the

equipment manufacturer or his representative for advice.
When working on operating equipment, be aware that some parts may have an elevated temperature. Any

operations on elevated level have to be executed with extra care to prevent accidents.

CAUTION

Do not cover units with PVC eliminators with a plastic tarpaulin. Temperature increase due to sun

radiation could deform the 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.
