27.0. OPTIONAL EQUIPMENT (Cont.):
27.21. OPTIONAL DROP IN CHILLER (Cont.):
27.21.4. TEMPERATURE CONTROLLER
27.21.4.1. This unit is supplied with a digital temperature controller mounted on
the front panel. See the attached instruction sheet for operating this
controller. A selector switch on the front panel tagged ATC/CTC sets
the controller to respond as an Ambient Tracking Controller (ATC) or
as Set-point Temperature Controller (CTC).
27.21.4.2. The ATC setting works to maintain the coolant at a adjustable
temperature differential relative to a fluctuating ambient temperature.
The AIR (ambient) sensor is mounted under the temperature controller
on the front panel. The coolant sensor is mounted in a dry well close
to the evaporator coils. The controller will alternate flashing the
ambient temperature and the coolant temperature.
27.21.4.3. The CTC setting works to maintain the coolant temperature within 0.5°
F of the adjustable set-point. The controller will alternate flashing the
set point temperature (S) and the actual temperature (F)
27.21.5. START - UP
27.21.5.1. Once the cooler has been installed and the proper electrical connections
have been made, it can be started by pressing the ON/OFF switch on
the front panel to the ON position. When the switch is pressed to the
ON position, an internal green light will energize and the compressor
and fan will start if the controller is calling for cooling (after a one
minute delay). Do not operate the cooler if the evaporator coils are not
completely submersed in coolant.
27.21.6. OPERATION
27.21.6.1. When the ON/OFF switch is pressed to the ON position, an internal
green light will energize and the compressor and fan will start if the
controller is calling for cooling (after a one minute delay). Set the
controller to the desired temperature.
27.21.6.2. When the controller calls for cooling, the compressor and condenser
fan come on after a one minute delay. Refrigerant is pumped by the
compressor through the expansion valve to absorb heat as it evaporates
in the evaporator/heat exchanger. When the controller calls for
heating, the compressor and fan shut down. The cooler should now be
ready for continuous operation.
27.21.7. SAFETY INTERLOCKS
27.21.7.1. HIGH TEMPERATURE INTERLOCK
27.21.7.1.1. This cooler has a HIGH TEMPERATURE interlock warning
built into the temperature controller. See ATC/CTC controller
instructions attached. If the coolant temperature exceeds the
high temperature setting the cooler will continue to run but
contacts across terminals #10 and #11 will open.
27.21.8. MAINTENANCE
27.21.8.1. Every Turmoil cooler is carefully assembled from the finest
components by skilled craftsmen. Each cooler is thoroughly tested
and inspected before it leaves the factory. However, in order to obtain
efficient service and long life from this cooler, it must be given proper
care as with any other piece of mechanical equipment
