MK Series Portable Chiller : Air-Cooled : HE INSTRUMENT
1.1 INTRODUCTION
A. This manual covers most 'MK' series portable chillers with air-cooled
condensers, from 5 to 30 tons.
B. When calling for assistance from the ADVANTAGE Service
Department, it is important to know the model and serial number
of the particular unit. The model number encodes critical unit
information which is helpful in any attempt to troubleshoot
operating difficulties. The serial number allows the service team to
locate manufacturing and testing records which can have additional
information relating to a particular unit.
1.2 UNIT LOCATION
A. The unit is designed for indoor use only. For most efficient
operation, locate the chiller in a clean, dry and well ventilated
environment.
B. The unit has an air cooled refrigerant condenser. For air cooled
condensers, a motor driven fan (on models from 5 to 15 tons) or a
centrifugal blower (on models from 15 to 30 tons) generates air
flow through the condenser to remove heat from the refrigerant
system. The air cooled condenser on the unit will discharge a
maximum of 15,000 BTU's per hour per ton of cooling.
C. The unit must have a minimum entering air temperature of 60°F
and a maximum entering air temperature of 95°F for efficient
operation.
D. The unit must have a minimum of two feet clearance at the air
intake and six feet at the vertical exhaust air discharge.
E. The unit must have all enclosure panels in place before operating
compressor. Air will not be drawn through the condenser coil if
they are not in place. This will cause the compressor to lockout on
the high pressure safety fault.
1.3 EFFICIENCY
A. Long term efficiency of operation is largely determined by proper
maintenance of the mechanical parts of the unit and the water
quality. ADVANTAGE recommends filtering where required to
prevent solids from plugging critical parts (pumps, heaters, seals for
example). ADVANTAGE highly recommends the services of a
competent water treatment specialist be obtained and his
recommendations followed. ADVANTAGE accepts no responsibility
for inefficient operation, or damage caused by foreign materials or
failure to use adequate water treatment.
