Note that the timer would also eliminate power from the heaters and the 
hydraulic pump during the cooling cycle.   

  

 
 
F. 

Fill the test cylinder with water by positioning the water supply valve to the "FILL CELL" 
position.  Water will flow into the test cell and air will be expelled from the loosened 
thermocouple connection. When water begins to flow from the thermocouple 
connection, tighten the thermocouple gland with a wrench.  When water begins to flow 
from the fitting on the test cell cap tighten the fitting.   

 
G. 

Apply pressure to the test cylinder by turning the "PUMP" switch to the "ON" position.  
The pressure may then be increased by turning the air regulator clockwise until the 
desired pressure is obtained.  This pressure is indicated on the pressure gauge.  
Pressure may be reduced by turning the regulator counter-clockwise and by slightly 
opening the "PRESSURE RELIEF" valve. 

 

APPLY HEAT TO THE TEST CELL  

 
The Eurotherm Model 818 is the most important component of the temperature control 
system and it is strongly recommended that operators carefully study the Model 818 
instruction manual. 
 
A. 

Program the temperature profile you wish to perform into the Model 818 Controller.  

 
B. 

Turn the "HEAT" switch to "ON" to activate the heaters.  

 
 

NOTE THAT THE PRESSURE WILL INCREASE SIGNIFICANTLY DUE TO THE 
THERMAL EXPANSION OF THE WATER AND THE TEST CELL SHOULD BE 
MONITORED CLOSELY UNTIL THE CURING TEMPERATURE IS ACHIEVED.  
SOME OPERATORS SLIGHTLY OPEN THE "PRESSURE RELIEF" VALVE TO 
HELP CONTROL THE PRESSURE DURING HEAT UP.   

 
C. 

The temperature controller will maintain the temperature schedule which was 
programmed and upon termination of a test it is imperative that the "HEATER 
SWITCH" is returned to the "OFF" position.   

 

TERMINATION OF TEST 

 
1. 

After the cement has cured for the required amount of time the "HEAT" switch should 
be turned "OFF". 

 
2. 

Immediately start the cool down procedure by turning the "COOLANT" switch to the 
"ON" position.  DO NOT release the test pressure until the temperature has been 
reduced to a minimum of 200 degrees F.
