Startup Checklists

 

 

4-1 Introduction

Follow the check lists below for the startup of your new chiller. These lists assume the installation information elsewhere in this manual has been read and followed. New chillers should be started up and checked by a qualified refrigeration service technician.

4-2 SMC Pre-Startup Checklist

1.Check the shipping papers against the serial tag to be sure chiller size, type and voltage is correct for the process that will be controlled.

2.Check the transformer primary voltage connections to be sure they are configured for the electrical power you are using. The voltage at the main power connection must read within +/-10% of the voltage listed on the serial tag. Electrical connections must conform to all applicable codes.

3.The chilled water TO PROCESS and FROM PROCESS connections should be completed.

4.Be sure the reservoir tank and chilled water circuit piping are filled with water.

5.The air-cooled condenser should have an adequate supply of air for proper operation.

6.Connect main power to the chiller and run the chiller just long enough to see if the pump is generating normal pressure.

7.Check your work and proceed to the SMC Startup Checklist section below.

4-3 SMC Startup Checklist

1. Turn ON the chiller. The SMC chiller should continue to run until the switch is turned

OFF.

2.Put the SMC chiller under a process load.

3.Set the microprocessor control to the desired process temperature setpoint using the

, , and buttons. See Chapter 5 on Page 27 for more information.
