Process temperature based on +100° F (+38° C) ambient.
Bronze models are rated to a maximum process temperature of +500° F (+260° C). Stainless steel models are limited
to the maximum temperature of the selected switch mechanism.
On condensing applications, temperature down-rated to +400° F (+204° C) process at +100° F (+38° C) ambient.
On models with bronze bodies with
3
⁄
4
" or 1" NPT pipe sizes, consult factory for HS switches.
HS switches are not available on models with stainless steel bodies.
