  • Page 8: Introduction

    Titan Central Chillers INTRODUCTION This manual covers Titan central chillers from 20 to 180 tons (70 to 633 kW) of cooling capacity using the Advantage MG microprocessor control instrument and fixed displacement scroll compressors and digital scroll compressors. The standard fluid operating temperature range for this chiller is 20°F to 80°F for units using R410A refrigerant. Units using other refrigerants have different standard operating ranges. Units operating below 48°F fluid require the use of a water/propylene glycol to prevent freezing.
  • Page 9 Titan Central Chillers WARNING: This equipment contains hazardous voltages that can cause severe injury or death. Disconnect and lock out incoming power before installing or servicing the equipment. WARNING: This equipment contains refrigerant under pressure. Accidental release of refrigerant under pressure can cause personal injury and or property damage. Exercise care while working on or around this equipment.

    Titan Central Chillers WARNING: Follow all Factory operations procedures. Failure to do so may create a hazardous operating condition which may result in serious operator injury and/or unit damage. GENERAL Failure to follow the factory required operations procedure may adversely affect the unit’s ability to adequately control process temperature and may create a hazardous operating condition which may result in serious operator injury and/or unit damage.
  • Page 27 Titan Central Chillers and the water supply will fill the reservoir tank. Do not use automatic fill when operating at temperature below 48°F. MANUAL FILL: Add fluid directly to the reservoir. When the pump is first started, as process lines are filled and air is purged, additional fluid may be required to restore the reservoir to the correct level. Verify reservoir level via the coolant sight glass. Do not use deionized water in this unit unless your unit was specifically designed for use with deionized water. Consult factory if not certain.
  • Page 28 Titan Central Chillers After electrical installation the rotation must be checked by observing the pump motor shaft on the end of the pump and comparing its rotation to the directional arrow on the motor. If the rotation needs to be changed it should be done at the main power entry by switching any two power conductors at the terminal block or customer supplied main power disconnect.
  • Page 29 Titan Central Chillers Incorrect rotation is “counter-clockwise” (incorrect phase) when viewed from the rear of the motor. If the shaft does not rotate when the ON/OFF SWITCH is on, the operator must identify the cause as outlined in the troubleshooting and repair section of this manual. If the motor shaft is phased correctly (shaft turns in a clockwise direction), continue with step C.
  • Page 30 Titan Central Chillers electric motor. The following example is the start up procedure for a two pump central chiller. Fully open the suction valves to the pumps allowing the pump case to fill with water. Never allow the pump to operate dry, this can cause shaft seal failure. Discharge Valve Suction Valve 2. Close the discharge valves. A centrifugal pump can be operated with no flow without damage, although this should not be for an extended period of time.

  • Page 31: Operator Controls

    Titan Central Chillers If during operations the motor overload trips, the overloads will need to be manually reset to restart operations. Once the pump is restarted, check for excessive motor amps at the motor starter block and throttle back the pump’s discharge valve as required. OPERATOR CONTROLS Depending on the unit’s standard and option configuration, the number of switches and buttons maybe different than shown below. A typical configuration is shown here.

Upon powered up, the instrument displays the Standby Screen.
  • Page 34 Titan Central Chillers PRECAUTIONS: The chiller control is programmed from the factory with a setpoint range of 48° to 70°F. To operate below 48°F, the addition of inhibited propylene glycol and modification of the limit control settings are required. These adjustments are done from the chiller controller screen. Diligent monitoring of the water/glycol solution is mandatory to prevent freezing of the evaporator.
