2.Adjust the tilt angle of the head by loosening the two hinge screws and tilting the head to the desired position. Tighten the hinge screws securely.

TO RESET THE DIAL

1.Determine the room temperature by using a reference thermometer of known accuracy.

2.Locate the reset screw on the back of the head (see Figure 1).

3.The numbered dial face inside the head will rotate as the screw is turned. Use a slotted screwdriver or a 14" hex wrench to adjust the setting.

4.Align the pointer with the correct temperature on the numbered dial face. The thermometer is now ready for installation.

INSTALLATION INSTRUCTIONS

The Model J DialTemp Thermometer is supplied with a 12" -14 NPT pipe thread for mounting purposes. Carefully screw the thermometer into the fitting by hand until slightly tight. Complete tightening by using a 58 " wrench on the wrench flats. When using a thermowell, tighten only FINGER TIGHT.

C A U T I O N

NEVER TIGHTEN BY TWISTING THE HEAD! AVOID

HANDLING THE THERMOMETER BY THE STEM OR BENDING

THE STEM.

To obtain a positive seal, coat the threads with pipe joint compound or wrap with Teflon tape.

When inserting the DialTemp into a semi-solid material, hold the stem firmly and insert slowly and carefully to avoid bending. When inserting the thermometer into a material, always hold it by the stem, not by the head.

OPERATING INSTRUCTIONS

For correct temperature measurement, the stem of the DialTemp must be immersed at least 2" in fluids and 4" in gases.
