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
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.
Fan cycling for multi-fan models
All fans should be operated simultaneously. Fan Cycling on each fan individually is not recommended.
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.
