5-2 Water-Cooled SSC Series Startup Checklist

þCheck the shipping papers against the serial tag to be sure chiller size, type and voltage is correct for the process.

þCheck the transformer primary voltage connections to be sure they are configured for the electrical power you are using.

þThe voltage at the main power connection must be within plus or minus ten percent (±10%) of the voltage listed on the serial tag.

þPhase imbalance must be less than two percent (<2%).

þElectrical connections must conform to all applicable codes.

þComplete the chilled water TO and FROM PROCESS connections.

þThe optional or field installed chilled water supply and return valves on the chiller must be open.

þBe sure the pump tank and chilled water circuit are filled with a water/glycol mixture that provides freeze protection to 20°F (12ºC) below the leaving water temperature you want.

þComplete the tower or city condenser WATER IN and WATER OUT connections. Provide an adequate condenser water supply; 2 gpm per ton for city water or 3 gpm per ton for tower water operation.

þRemove all tools, foreign matter and debris from the pump tank reservoir and piping.
