  • Page 18 If the trap is to be situated in an exposed position, it should be either lagged or drained by a separate small thermostatic trap such as the Spirax Sarco No.8, or Bydrain. Always fit a non-return (check) valve downstream of any steam trap which discharges into condensate return lines where back pressure is experienced.

  • Page 29 6.3 FT mechanisms (DN40 only) Baffle arrangement used on FT43, FT44, FT46 and FT47 (horizontal only) In line with our policy of continuous product improvement, we have found it beneficial to add a baffle plate over the inlet port. This eliminates any risk of flow from the inlet port affecting the correct operation of the float. When fitting the mechanism, assemble the baffle plate supplied under the mechanism retaining bolts.
