Calibrate Seal 500T-X dry mount press

[jmvdigital]

I'm trying to find instructions on calibrating my newly acquired Seal 500T-X dry mount press. It seems to run 10-15 degrees hotter than the dial set. The best I can find is in the instructional manual, and just says to contact Seal for instructions. My searching on google and on here has proven fruitless so far. I'm guessing it has something to do with the brass nut/screw assembly inside the temperature control knob.

Thanks,

Nevermind, I was able to find a full maintenance manual that was posted as part of an ebay listing for a 500T.

For those interested:

THERMOSTAT CALIBRATION

 
Tool required:
      One small straight blade screwdriver

Procedure:
1. If your press is not equipped with a thermometer, a device to measure the platen temperature will be needed.  If a pyrometer with thermocouple is used, the thermocouple should be placed under the platen near the thermostat.  Temperature indicator strips are also available from your local distributor.  Calibration is accomplished as follows:

2. Set the thermostat knob as 350 degrees F and allow the press to heat up and stabilize approximately 15 minutes.  This should be done with the press top resting on the sponge pad.
 
3. Remove the thermostat knob without turning the shaft by loosening the setscrew in the side of the knob.
 
4. Noting that the shaft is hollow, insert a small straight blade screwdriver down the shaft and turn slightly, feeling for the screw.  Do not turn the screw.
 
5. If the temperature of the press is below 350 degrees F, wait for the amber heater indicator light to go out.  Immediately upon shutting off, turn the screw until the light turns back on, then turn the screw 1/8 of a turn further.  (See chart at end of instructions for proper direction of turn according to type of thermostat).  Note: Be certain the shaft does not turn while turning the adjustment screw.
 
6. The amber light turns on when the heater is on.  Allow the press to stabilize again.  If the temperature is still below 350 degrees F, repeat the above instructions.
 
 
7. If the actual temperature is above 350 degrees F, wait for the light to turn on.  Immediately turn the screw (making sure the shaft does not turn) until the light goes out.  Repeat these steps until the thermostat is calibrated.
