➀
Models are limited to maximum temperature rating of selected switch mechanism.
➁
Minimum SG ratings apply to single stage units. Consult factory for two and three stage units.
➂
600# and 900# flanged cage models must use switch codes listed under heading “Model C34
& All Models w/Materials of Construction Codes 2 or N and B3F, G3F, K3F & Z3F with 600# or
900# ANSI rating”.
➃
HS switches can be used with Materials of Construction Code 1 only.
Example: B3F-1B80-HSG.
➄
Consult factory for 14" center-to-center dimensions on model K3F.
➅
Construction Code N is not applicable to this unit due to 17–7 ph stainless steel float material.
➆
Consult factory for Model C34 up to +750 °F (+399 °C).
➇
Codes for 150 lb. flanges are not applicable to the C34 displacer model.
➈
Codes for a 16" center-to-center dimension are applicable to the K3F model only.
