OPTIONAL SYSTEM FEATURES
Coolant Water Filter
The factory installed water filter removes particulate from the coolant water. The water filter is not recommended
with centrifugal pumps or turbine pumps. For replacement filters, call Lytron’s Customer Service at 781-933-
7300.
Deionization Package
The Deionization Package consists of a factory-installed deionization cartridge. The deionization cartridge
requires replacement only when the mixed bed is depleted. For replacement cartridges, Call Lytron’s Customer
Service at 781-933-7300. This package is offered for deionized water applications where the resistance of the
water does not exceed 1 Mega-ohm-cm. The deionization package is not recommended with centrifugal pumps.
External Customer Contacts
This option will send a signal indicating there is a problem with the chiller. It can be wired to open on fault or
close on fault. This connector is located on the rear left of the system. Pin 5 is the common, Pin 6 closes on
fault, and pin 4 opens on fault. The mating connector is Amp part number 350715-1, and the pins for the
connector are Amp part number 350547-1. These contacts are rated for 250 V, ½ amp maximum.
External Manually Adjustable Flow Valve
This option allows the flow rate to the equipment to be controlled with a globe valve. Opening the valve allows
the flow to bypass from the supply to the return. By adjusting the valve a precise flow rate can be set. To be
sure the process equipment is receiving the appropriate flow install a flow meter at the outlet from the process
equipment
.
External Pressure Relief Valve
This option is for applications with a maximum allowable pressure. It can also be used where flow to the
equipment being cooled needs to be shut off without stopping the chiller. In this case the pressure relief valve
will open and allow the flow to bypass from the supply to the return. The standard valve has an adjustment
range from 50 psi to 100 psi.
Fault Chiller Shut-off
This option will shut the chiller off in the event that there is an alarm condition. It will turn off the power to the
pump and compressor and give an error signal on the front panel of the chiller. To reset the system after a fault
the main power must be turned off at the circuit breaker.
Heater Package RC011, RC022, RC030 and RC045
The heater package is for applications requiring coolant temperature well above ambient temperature. This
package is a single set point type. The heater is activated when the water temperature is 3
°
F below set point.
The heater option is not intended to provide tight temperature control, but to bring coolant temperature up to an
application's requirement faster than the refrigeration cycle (hot gas bypass).
High Purity Plumbing
This option is intended for use with deionized water. Only stainless steel and/or plastic components and a
nickel-brazed heat exchanger come in contact with the coolant. This option must be specified before the chiller
is purchased. It cannot be upgraded in the field.
Remote Start
This option allows the Kodiak chiller to be started or stopped through a computer or a relay. The chiller can e
run using a normally open circuit or normally closed. (Look under the section labeled Chiller Operation for more
details) R.S. contacts are located on the rear left of the chiller shown previously. It is a six-pin connector with
pins 1 and 2 controlling R.S. The mating connector is an Amp 350715-1 plastic housing. The pins are Amp
350547-1. The controlling relay should have SPDT type contacts rated for low current less than or equal to
5VDC at 0.1 milliamp.
