Contact OPTI TEMP for further information at 231-946-2931 or information@optitemp.com. CAUTION: The OPTI TEMP system is designed as an “open system” with the top of the reservoir at atmospheric pressure. Do not connect any fittings to the cover of the reservoir or pressurize the reservoir in any way or damage to the system and/or personal injury could result. -

Page 26: Fluid Bypass Valve Setting And Adjustment
NOTE: Couplings and clamps are preferred to quick connect fittings because they have the potential for restricting the flow rate. CAUTION: Please contact OPTI TEMP if your process is equipped with a valve, which may periodically interrupt flow to the process. Bypass settings may be critical to protect the... -

4. Turn the unit on for approximately 30 seconds to ensure the propylene glycol has had a chance to contact all of the wetted internal components. 5. Turn off the chiller and remove power from the unit. 6. Open the system drain connection (if applicable). Drain as much fluid as possible. 7. -
Page 28: Section 9 - Troubleshooting
If the chiller’s process fluid temperature is 5 degrees colder than the controller’s fluid set point, the Opti Temp chillers are programmed to shut off the compressor until the process fluid temperature warms up to the desired process fluid set point. In addition, a “freeze alarm”... -
Page 29: Low Refrigerant Check
9.1 Low Refrigerant Check Unfortunately, leaks happen. Opti Temp Inc. ships chillers all over the world and even with the best testing and packaging a large shock is all it takes to create a leak. So if you think maybe your chiller has lost its refrigerant, this guide will help you determine if it has or has not. - Page 30 arrangement with one controller on the unit and a second located remotely. In this case, set the Local/Remote switch to Local to make it easier to diagnose. 2. The second item is the refrigerant sight glass (Figure 1). This is a window into one of the refrigerant lines.
