GENERAL INFORMATION REGARDING DESIGN TEMPERATURE Our custom chiller systems are designed to maintain the temperature of cooling fluids within a selected temperature range. Each of our units is tested through monitored operation within design parameters. technicians This to enables calibrate our all experienced instrumentation precisely to the customers needs and verify that each individual unit will function as specified. Figure 1.
9. Run power wiring to the chiller’s main disconnect. Conductor size should match the chiller’s disconnect size and power requirements in accordance with local codes. Ensure the power supplied matches the chiller data plate requirement for voltage, frequency, and amperage. 10. All inclusive units are shipped with the proper refrigerant charge in place. No adjustments should be necessary to the refrigeration system before startup. Refrigeration service valves are shipped in the open (back-seated) position.
PRE-STARTUP PROCEDURE: 1. Complete all steps of the installation process before applying power to the chiller. 2. If the unit is equipped, ensure the system switch is in the OFF position, then turn on the main power disconnect. The temperature controller will turn on and automatically go into a self-test. When the self-test is complete, the controller will begin to monitor the process fluid. 3.
pressure gauges and make note of initial pressures. The pump may need to run for several minutes to allow any air to be worked out of the system before regular flow is established. Any fluid bypass valves in the system should be factory set according to customer specifications but may need slight adjustment in the field. Consult the factory before making any adjustments to the system. 5. Check the entire fluid system for leaks and ensure there is flow throughout the system. 6.
Visually check for fluid leaks throughout system. Physically check for loose pipe fittings or hoses. Ensure that no plumbing parts are wearing, cracking, or chafing. 5. Check voltage & amp draws Check for proper incoming voltage and current draws on all motors and heaters. Refer to the chiller’s electrical schematics or the motor nameplate for proper voltage and amperage ratings. Readings should be within +/- 10% of the nameplate and have a maximum difference of +/- 2% between each phase. 6.
PROPYLENE GLYCOL: Propylene glycol maintains generally the same freeze protection, corrosion and algae prevention as ethylene glycol, but has a lower level of toxicity. This type of glycol is more readily disposable than ethylene and safer to handle. Propylene glycol is commonly used in the food industry and in applications where the user may come in frequent contact with the fluid. Dimplex Thermal Solutions recommends the use of K-Kool Glycols in its units.
TROUBLESHOOTING GUIDE: This guide should serve as a general outline for troubleshooting issues with all Dimplex Thermal Solutions chillers. Due to the various models of DTS chillers, the items listed in possible causes may not apply to every DTS chiller. Contact the DTS customer service department for assistance at 1-800-YOU-KOOL Refer to the Warranty Procedures section of this manual before having any work performed on units that are under warranty.
Low refrigerant pressure fault (Automatically reset when satisfied with pressure) Low ambient air temperature. Loss of fluid flow through evaporator. Loss of refrigerant. Refrigerant solenoid not functional. Faulty pressure switch. Compressor crankcase not warm or faulty crankcase heater. AIR COOLED CHILLERS: Air filters dirty. Condenser dirty. Incoming air too hot. Inoperative fans. Back panel out of chiller. Phase rotation incorrect. Refrigerant system overcharged.
GENERAL WARRANTY PROCEDURES: WARRANTY WORK: Before doing any work on a chiller covered under warranty, call Dimplex Thermal Solutions (DTS) and explain the problem to one of our service technicians who can then determine the best course of action. DTS will not be obligated to pay for warranty service performed without our prior approval. Refer to the Warranty section of this manual on the specific terms of warranty for your chiller.

HAZARDS IDENTIFICATION Potential Health Effects INHALATION ETHANE, 1,1,1,2-TETRAFLUOROGross overexposure may cause: Central nerous system depression with dizziness, confusion, incoordination, drowsiness or unconsciousness. Inhalation of high concentrations of vapor is harmful and may cause heart irregularity unconsciousness or death. Intentional misuse or deliberate inhalation may cause death without warning. Vapor reduces oxygen available for breathing and is heavier than air.
(2008FR) (continued) FIRST AID MEASURES CONTINUED, INGESTION Ingestion is not considered a potential route of exposure. Notes to Physicians Because of possible disturbances of cardiac rhythm catecholamine drugs, such as epinephrine should only be used with special caution in situations of emergency life support.
ACCIDENTAL RELEASE MEASURES Safeguards (Personnel) NOTE: Review FIRE FIGHTING MEASURES and HANDLING (PERSONNEL) sections before proceeding with clean up. Use appropriate PERSONAL PROTECTIVE EQUIPMENT during clean up. Accidental Release Measures Ventilate area, especially low or enclosed places where heavy vapors might collect. Remove open flames. Use self-contained breathing apparatus (SCBA) for large spills or releases.
