Page 4: Safety & Environmental Concerns
SAFETY AND ENVIRONMENTAL CONCERNS Your Mydax chiller was designed to give years of trouble-free operation. Features were designed into the unit to provide early warning of failure mechanisms so that catastrophic failures can be avoided. Whether a chiller is at the factory or in the field, diagnostic information gives Mydax engineers insight to the operation of each stage of the refrigeration and recirculation circuits without having to attach service gauges. - Page 5 Refrigerants are fluorocarbon type materials and subject to environmental regulations. The compressor uses POE oil; this MSDS is available from Mydax upon request. The compressor is hermetically sealed and no service should be required. In the event that cleanup is necessary, absorb oil with oil absorbent material and dispose of as a hazardous waste.

Page 6: System Overview
The superheat valve passes only enough refrigerant to maintain the proper gas temperature at the suction inlet of the compressor. Using this technique, Mydax is able to run in load conditions of zero to full load and all combinations in between. - Page 7 Mydax, Inc. 1M150W Water Cooled Chiller System Electrical Diagram Refer to drawing #D2923, the system electrical diagram. The central component of the electrical system is the M1001 controller. It is microprocessor-based and communicates with and/or controls various other circuit boards and components.

Page 8: Installation
This display indicates that the microprocessor is initializing. After a few seconds, the controller will finish initializing and the "Warm-up Delay" message will return to simply "Mydax". Leave the unit turned on while hooking up the following plumbing connections. This will allow time for the crankcase heater to warm the compressor and separate the oil from the refrigerant. - Page 9 300K and 500K ohms. On a yearly basis, or if the unit is unable to maintain resistivity to acceptable level, replace with Mydax part# F1003. This mixed-ion resin cartridge filter is only available from Mydax.

Page 12: Alarm & Error Messages
Water Cooled Chiller ALARM & RROR MESSAGES A unique feature of Mydax systems is the error messages displayed on the 2 by 40-character liquid crystal display (LCD). The microprocessor constantly checks various points and parameters throughout the system and automatically displays messages when error conditions are sensed. -
Page 13: Diagnostic Displays
Water Cooled Chiller DIAGNOSTIC DISPLAYS Mydax chillers are provided with a computerized self-diagnostic capability. This system is equipped with 9 different test panels, which are accessed by pressing the TEST key, followed by the test panel number. Diagnostic mode is terminated... - Page 14 Mydax, Inc. 1M150W Water Cooled Chiller maintain temperature stability, and give the magnitude and timing of the change. The center of the display shows readings for the RTD "Zero" and "Gain" calibration resistors. Precision 100Ω and 120Ω resistors (0.1% tolerance or better, representing ideal nominal RTD's) are used as a reference.
- Page 15 Mydax, Inc. 1M150W Water Cooled Chiller TEST PANEL #8: Fill Tank ! Alarms: Run 356d 11:31:25 The top left side of this display shows the alarm (error message) history. If there have been no alarms since the last history reset, the display reads "No Alarms". If alarms have occurred, the display shows them in sequence, like the main display.
