Type 99

1. The pressure/temperature limits in this Instruction manual and any applicable standard or code limitation should not be exceeded.

2. For stability or overpressure protection, a pilot supply regulator may be installed in the pilot supply tubing between the main valve and pilot.

3. Type 61LD construction has narrower proportional band than does the standard Type 61L pilot.

4. Type 61LE construction has broader proportional band than does the standard Type 61L pilot.
