Severe Operating Conditions Service
The following recommended maintenance
procedures are basic requirements for normal
operating environments. For severe operating
conditions, the frequency of inspection and
service should be increased. Air containing
industrial and chemical fumes, salt, dust, or
other airborne contaminates and particulates
will be absorbed by the recirculating water
system and may form solutions and deposits
harmful to the products and personnel.
Safety
The recirculating water system contains
chemical additives for water quality control
and biological contaminants removed from
the air by the washing action of the water.
Personnel exposed to the saturated effluent,
drift, or direct contact should use proper
precaution.
Proper location of the
evaporative-condensed chiller requires good
judgment to prevent the air discharge from
entering fresh air intakes or to avoid allowing
contaminated building exhaust from entering
the condenser.
Figure 33 - Proper Unit Location
Follow local and national codes in locating
the evaporative-condensed chiller, but as
minimum the sump must be 15 feet from the
nearest intake.
Figure 34 - Improper Unit Locations
Performance
Improper location of the evaporative-
condensed chiller may seriously degrade the
capacity of the equipment. Make sure the
equipment is located such that discharge air
from the condenser does not enter the
condenser air inlet.
Batch-loading chemicals into the unit
is NOT PERMITTED. The control
system must regulate the chemical
feed.
WARNING
The evaporative-cooled condenser
must be thoroughly cleaned on a
regular basis to minimize the growth
of bacteria, including Legionella
Pneumophila, to avoid the risk of
sickness or death. Service personnel
must wear proper personal protective
equipment. Do not attempt any
service unless the fan motor is locked
out.
