GENERAL INFORMATION

Operating conditions

BAC cooling equipment is designed for the operating conditions specified below, which must not be exceeded

during operation.

Wind Load

: For safe operation of unshielded equipment exposed to wind speeds above 120 km/h installed at a

height above 30 m from the ground, contact your local BAC-Balticare representative.

Seismic Risk

: For safe operation of equipment installed in moderate and high hazard area's contact your local

BAC-Balticare representative.

Standard electrical motors are suitable for an ambient temperature range from -25°C to +40°C.

Maximum inlet pressure: 0.5 bar

Water inlet temperature: max. 55°C (std. fill) or 65°C (high temperature option)

Water outlet temperature: min. 5°C

For circulating water quality compatible with construction materials refer to section"About water care" on page 9

Actual spray pressure is indicated on technical data sheet supplied with order acknowledgement.

Connecting pipework

All piping external to BAC cooling equipment must be supported separately.
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.
