Once communication has been established, proceed to the parameter list shown in Appendix 
A and check the following parameters to display their real time data being streamed from the 
1314: 

 

 

RTD_TEMP_PRE 

 

RTD_TEMP_POST 

 

THERMISTOR 

 

FLOWRATE (GPM) 

 

THERMOPILE 

 

The RTDs and ambient values should now display real time data of values close to the current 
laboratory environment (typically ~ 25C). The thermopile should display a value close to 0 
(typically .0009 or so) as there is no temperature differential taking place yet with no fluid or flow 
present. The flowrate should display 0 as there is no fluid present and the pump has not been 
turned on yet. This flowrate value will guide you to establishing the proper flowrate once the 
pump has been turned on. The unit is now ready to prime the pump and the proper flowrate will 
be adjusted to a value of .5 to .55 GPM using the flow adjust knob on the rear of the 1314 unit as 
described in the next section

Connect the Chiller and Prime the Coolant Pump 

1.

 

Connect the chiller serial cable to the PC USB port.  

2.

 

Ensure the supply outlet hose of the chiller is connected to a filter then the inlet of the 1314. 

3.

 

 Make sure the outlet hose of the 1314 is connected to the return inlet of the chiller. 

4.

 

 Locate the main power switch on the back side of the chiller, turn it ON.
