PCA Series Chillers
4 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 PCA 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 /-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
PCA Startup Checklist
section below.
4-3 PCA Startup Checklist
1. Turn
ON
the chiller. The PCA chiller should continue to run until the switch is
turned
OFF
.
2. Put the PCA chiller under a process load.
3. Set the microprocessor control to the desired process temperature setpoint using
the
,
, and
buttons. See Chapter Five on Page 25 for more
information.
4. Check the pump amp draw and pump pressure. The amp draw reading must be
within the running load and service factor amps.
5.
Operate the chiller, looking for leaks and listening for unusual noises or
vibrations that could indicate improper operation.
