INSTALLATION, OPERATION AND MAINTENANCE MANUAL

Basic configuration - Body style double flanged, wafer, lug and buttweld

SECTION 2 - KEY POINT OF WHEN YOU

DISASSEMBLY OR ADJUST EXHAUST

TEMPERATURE

Shut the stop valve of Thermocon valve

before you disassemble or adjust exhaust

temperature.

Disassemble or adjust exhaust temperature

after you confirm that surface temperature of

Thermocon valve is cooled down as cool as you

can touch it by your hand.

If you disassemble or adjust exhaust

temperature without enough cooling,

Thermocon valve does not operate good due to

too much expansion of bellows.

right when lower temperature is desired.

Each revolution should lower the

temperature by 2O °C.

5. Limit of temperature adjustment is between

5O °C - 1OO °C.
