It incorporates significant breakthroughs in water-cooled chiller technology to provide excellent reliability and achieve superior efficiencies at true operating conditions without compromising the environment. The 23XRV chiller provides: • Variable speed, positive displacement screw compressor. • Air Conditioning, Heating, and Refrigerant Institute (AHRI) certified efficiencies to 0.33 kW/ton (AHRI IPLV). • Chlorine-free HFC-134a refrigerant. • IEEE-519 compliance for harmonic distortion. • An

NOTES: 1. Main power must be supplied from a field-supplied fused electrical service with a (factory-or field-installed) disconnect located in sight from the unit. 2. Control circuit power must be supplied from a separate source through a field-supplied disconnect. The control circuit accessory transformer may be applied to power from the main unit power supply. 3. Maximum incoming wire size for each terminal block is 500 kcmil. 4. Maximum allowable phase imbalance is: voltage, 2%; amps, 5%. 5.

Be sure you understand and follow the procedures and safety precautions contained in the machine instructions as well as those listed in this guide. DO NOT USE OXYGEN or air to purge lines, leak test, or pressurize a machine. Use nitrogen. NEVER EXCEED specified test pressures. For the 16DF machine, the maximum pressure is 12 psig (83 kPa). For the chilled/hot water and condensing water piping, the maximum pressure is stamped on the machine. WEAR goggles and suitable protective clothing when han
