MAINTENANCE INSTRUCTIONS
Baltimore Aircoil Company equipment needs to be
properly
installed,
Documentation of the equipment used, including a
drawing, technical data sheet and this manual should be
kept on record. To achieve long, trouble-free and safe
operation, it is necessary to establish an operating plan
including a programme of regular inspection, monitoring
and maintenance. All inspections, maintenance and
monitoring actions should be recorded in a cooling system
logbook. The operating and maintenance instructions
published here can be used as a guide to achieve these
goals.
In addition to establishing the operating plan and the
cooling system logbook it is recommended to conduct a
cooling system risk analysis, preferably by an independent
third party.
For the cooling system, scale, corrosion and biological
control must be established and initiated when the system
is first filled with water and administered on a regular
basis thereafter in accordance with recognized Codes of
Practice. Water sampling, test results and corrective
actions should be recorded in the cooling system logbook.
For more specific recommendations on keeping your
cooling system efficient and safe, contact your local BAC
representative.

WATER CARE About Water Care Passivation In all cooling equipment, operating in evaporative mode, the cooling Galvanised steel units require passivation in order to prevent white is accomplished by evaporating a small portion of the re-circulating rust. Passivation is the formation of a protective, passive, carbonate layer water as it flows through the equipment. -

Minor fouling can usually be removed chemically or by temporary changes to the water treatment programme. Contact your water treatment supplier for advice.
- Page 8 MAINTENANCE PROCEDURES Under normal operating conditions the bearings should be greased every 2000 operating hours or at least every six months. The bearings should be lubricated with one of the following water resistant inhibited greases, which are good for ambient temperature ranging from - 55°C to 120 °C.
