Page 6: Warnings
Section I Safety Warnings Make sure you read and understand all instructions and safety precautions listed in this manual before installing or operating your unit. If you have any questions concerning the operation of your unit or the information in this manual, contact our Sales Department (see After-sale Support). -
Page 7: General Information
Section II General Information Description The DIMAX Liquid to Liquid Heat Exchanger is designed to remove heat loads from liquid-cooled instruments. The unit uses facility cooling or tap water as the secondary cooling medium to remove heat from the primaryfluid in the closed recirculation loop. -

Specifications Temperature Range +20°C to +30°C Pumping Capacity Flow rate (gallons per minute) Facility Water Requirements Flow rate (gallons per minute) Reservoir Volume Gallons 68.0 Liters Unit Dimensions (H x W x D) Inches 55 x 32½ x 32½ Centimeters 139.7 x 82.6 x 82.6 1. -
Page 9: Site
Section III Installation Site The unit should be placed in a location with easy access to a facility cooling water and a drain. For proper ventilation, a minimum clearance of 6 inches ( 15 centimeters) at the rear of the unit is necessary. Never place the unit in a location where excessive heat, moisture, or corrosive materials are present. - Page 10 - 8 -...

Page 11: Plumbing Requirements
The multi-conductor cable has 3 current carrying conductors and 1 non- carrying conductor (Ground). Each cable conductor is made of stranded copper, and is at least size AWG 12. The multi-conductor flexible jacketed cable is type S, SO, ST and STO with insulation rated for a minimum of 600 V, 75°C (140°F). -
Page 12: Fluids
The unit’s pump is capable of generating up to 40 psi. The SUPPLY plumbing should be rated to withstand that pressure. Tubing and insulation are available from Thermo. Contact our Sales Department for more information (see Preface, After-sale Support). It is important to keep the distance between the unit and the instrument being cooled as short as possible, and to use the largest diameter tubing practical. -
Page 13: Microprocessor Controller
Microprocessor Controller The controller has four different loops. An alphanumeric LCD display presents numeric readings of various operating conditions within the chiller. Display function is selected by pressing the appropriate keys to move through a menu of available information. Various controller loops allow the operator to display and/or alter different parameters of the controller. - Page 14 Operators Loop When the controller is first powered it goes through a short self test and then enters the Operators Loop, displaying the temperature of the fluid in the reservoir, the resistivity of coolant leaving the chiller, the facility water flow rate and any fault message.
- Page 15 Setup Loop The setup loop allows the operator to change the DI setpoints and flow alarm limits. To enter this loop you must be in the operators loop and displaying the tem- perature. Depress and hold the ENTER key while pressing the NEXT key. Scroll through the SETUP menu using the NEXT or LAST key, press ENTER to go to the desired sub-menu.
- Page 16 Configuration Loop The configuration loop allows you to configure frequency, enable the buzzer and verify software version number. To enter this loop you must be in the operators loop and displaying the temperature. Depress and hold the ENTER key. While holding the ENTER key enter the key sequence NO-YES-NO.

Page 18: Fault Messages
Fault Messages Fault messages are displayed in the Operators Loop and the alarm will sound. The faults are proiritized. When a fault is cleared and RESET is pressed, the next prioritized fault is displayed. The messages below are listed from highest to lowest priority. -
Page 19: Start Up
Section IV Operation Start Up Connect the unit to a power source, refer to Section III Installation. See unit serial tag for power supply requirements. Before starting the unit, check all plumbing connections and make sure the circulating system (the DIMAX, your application, and the tubing that connects them) has been properly filled with cooling fluid. -
Page 20: Flow Transducers
Flow Transducers Flow transducers are connected to return lines one through eight as well as the facility water inlet line. The transducers monitor the flow rate of the cooling fluid returning from your application and the facility water flow. Flows are displayed on the controller's Operators Loop. -
Page 21: Remote Interface
Remote Interface The temperature of the cooling fluid and the status of the low flow and low fluid detectors can be monitored by an external device using the monitor receptacle located on the control panel. Monitor receptacle Pin #1 Flow monitor output (return #1), active if flow is satisfactory sink current. Pin #2 Flow monitor output (return #2), active if flow is satisfactory sink current. -
Page 22: Resistivity Sensor
Resistivity Sensor The controller displays and maintains resistivity between adjustable setpoints. If the resistivity goes above the high setpoint, the line through the DI cartridge closes. Flow through the DI cartridge resumes when the resistivity drops to the low setpoint. If the resistivity drops below the low setpoint for more than one hour, a fault is displayed, the REPLACE CARTRIDGE LED illuminates and a remote signal is generated. -

Page 27: Service Contracts
Section V Maintenance Service Contracts Thermo offers on-site Service Contracts that are designed to provide extended life and minimal down-time for your unit. For more information, contact our Service Department (see Preface, After-sale Support). Deionizing Cartridge When the resistivity drops below the low setpoint for more than one hour the REPLACE CARTRIDGE LED illuminates. - Page 28 Section VI Service & Troubleshooting For personal safety and equipment reliability, the following procedure should only be performed by a qualified technician. Contact our Ser- vice Department for assistance (see Preface, After-sale Support). Algae To restrict the growth of algae in the reservoir, it is recommended that the reservoir cover be kept in place and that all circulation lines be opaque.
