GA Drawing

 

  • Do not use excessive forces Wide fixing nozdes/ couplings. Use thread sealing for leak-tight joints. Do not hold switch in vice or wrench.
  • Do not exceed electrical rating of the read switch. Use auxiliary relay or contactor for higher current rating and extra number of contacts
  • Do not exceed normal pressure rating of the switch for standard models. Consult manufacturer for higher system pressure.
