NTRODUCTION
This equipment is a factory built and tested packaged chiller designed for the
purpose of cooling water or other non-corrosive liquid. The liquid to be cooled is
circulated through the tubes of a evaporator where the temperature is reduced to
the desired level. The heat absorbed by the refrigerant in the evaporator is rejected
via the condenser where it raises the temperature of another liquid stream (usually
water) being circulated through the tubes. This heat is usually rejected by a cooling
tower or closed circuit evaporator.
To assure satisfactory operation and to avoid damage to the unit, the installation
should be made by a qualified refrigeration mechanic. The reader of this manual
and those who install, operate and maintain this equipment should have basic
understanding of the principles of air conditioning, refrigeration and electrical
controls. These instructions are general in nature and are for standard catalog units.
Non-standard units may vary in some respects from these instructions.
Dunham-Bush packaged chiller has been manufactured under a careful quality
control system. It has been tested for performance at the factory at specified field
operating conditions as a final verification of reliability. If it is installed, operated
and maintained with care and attention, it will give many years of satisfactory
service.
