Temperature Operating Range: 32°
to 220° F (0° to 104° C).
Installation: The 125, 250 and
375 series can be mounted in any position. The 500 and 750 series
can be mounted in any position except with the outlet port down.
We suggest the unit be calibrated in the attitude in which it
will be installed. An actuation point approximately 3 or 4 times
normal flow rate should be chosen to avoid the valve actuating
from initial pressurization of the system and normal surges. If
flow is kept constant, an actuation point 10% above the normal
rate may be used.
