GENERAL INFORMATION
Introduction
Baltimore Aircoil Company is the right choice when it comes to having a more efficient, safe and effective
system.
The BCP2D automatic dosing and bleed control is a compact package that offers accurate, high quality, liquid
chemical based water treatment for evaporative cooling equipment.
The BCP2D control package provides for water meter controlled proportional dosing of a scale and corrosion
inhibitor, automatic conductivity based control of dissolved solids level in the recirculating water through blow
down, as well as automatic time based dosing of a biocide.
Together with the implementation of a monitoring program, this equipment will assist with the implementation of
optimum water quality treatment, with effective and safe control of the water quality and bacteriologic growth,
including Legionella Pneumophilia, and reducing operating costs, chemical usage, and maintenance.
Following the guidelines listed in this manual will help to ensure the safety of all personnel who maintain the unit
and related equipment. If there are any questions on the procedures or performance of the BCP, contact your
local BACrepresentative.Name, e-mail and phone number can be found on the website www.BACservice.eu
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.
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.
For more information consult your local BAC 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.
Disposal requirements
Dismantling of the unit and treatment of refrigerants (if applicable), oil and other parts must be done with respect
to the environment whilst protecting workers from potential risks related to exposure to harmful substances.
National and regional legislation for material disposal and protection of workers should be taken into account
with regard to:
• Appropriate handling of construction and maintenance materials when dismantling the unit. In particular
when dealing with materials that contain harmful substances, such as asbestos or carcinogenic substances.
• Appropriate disposal of the construction and maintenance materials and components such as steel, plastics,
refrigerants and waste water according to local and national requirements for waste management, recycling
and disposal.
Non-walking surfaces
Access to and maintenance of any component needs to be performed in accordance with all local applicable
laws and regulations. If the proper and required access means are not present, temporary structures need to be
foreseen. Under no circumstance can one use parts of the unit, that are not designed as an access mean,
unless measures can be taken to mitigate any risks that might occur from doing so.
