• BAC units are typically installed immediately after shipment and many operate year round. However, if the unit is to be stored for a
prolonged period of time either before or after installation, certain precautions should be observed, as outlined in “Storage & extended
Shutdown” on
.
• Covering the unit with a clear plastic tarpaulin during storage can trap heat inside the unit and cause damage to the PVC components.
If units must be covered during storage, an opaque, reflective tarp should be used.
• Do not use steam or high pressure water to clean PVC eliminators, PVC water diverter, or materials other than steel.
• Do not use high pressure water exceeding 60 psi to clean the hCore
®
Heat Transfer Technology
• Do not use sharp or pointed objects, including screwdrivers and similar, for cleaning the hCore
®
Heat Transfer Technology.
• If noise or vibration persists, shut the unit down and correct the cause before continuing operation.
• Never use chloride or chlorine based solvents such as bleach or muriatic (hydrochloric) acid to clean stainless steel. It is important to
rinse the surface with warm water and wipe with a dry cloth after cleaning.
• The basin heater is not designed to prevent icing during unit operation.
General Maintenance Information
Equipment Precautions
NOTICE
The services required to maintain a piece of evaporative cooling equipment are primarily a function of the quality of the air and water in the
locality of the installation:
•
AIR:
The unit should be located such that unusual quantities of industrial smoke, chemical fumes, salt, or heavy dust do not enter the
equipment. Such airborne impurities entering into the equipment and absorbed by the recirculating water, which can form a corrosive
solution.
•
WATER:
As water evaporates from the equipment, dissolved solids are left behind, which were originally contained in the make-up water.
These dissolved solids may be either alkaline or acidic and as they are concentrated in the circulating water, they can cause scaling or
accelerated corrosion.
The extent of impurities in the air and water determines the frequency of most maintenance services and also governs the extent of water
treatment which can vary from a simple continuous bleed and biological control to a sophisticated treatment system. Refer to “Water
Treatment” on
for more details.
Warranties
Please refer to the Limitation of Warranties in the submittal package applicable to and in effect at the time of the sale/purchase of these
products. Described in this manual are the recommended services for start-up, operation, and shutdown, and the approximate frequency
of each.
•
CAUTION
: S
teps must be taken to avoid operation at or near system resonant frequency which could result in fan failure and possible
personal injury or damage.
•
CAUTION
:
The optional UV System includes a UV bulb that contains mercury. If the lamp breaks, avoid inhalation or ingestion of the
debris and avoid exposure to eyes and skin. Never use a vacuum cleaner to clean up a broken lamp as this may scatter the spilled
mercury. Obey local regulations and guidelines for the removal and disposal of mercury waste.
