Page 16: Installation
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 backpressure is experienced. -
Page 17: Operation
4. Commissioning After installation and maintenance ensure that the system is fully functional. Carry out tests on any alarms or protective devices. After installation or maintenance always open isolation valves slowly to mitigate system shocks and check for leaks. Ensure that the system is fully functional and carry out tests on any alarms or protective devices. The trap can be cold hydraulic tested, up to 1.5 times the PMA as per section 2, without the need to remove any internals. -

Page 19: Spare Parts
Always order spares by using the description given in the column headed 'Available spares' and state the size and type of trap, including pressure range. Example: 1 - Maintenance kit for a Spirax Sarco DN25 FTC62-62 ball float steam trap. IM-P179-15 CMGT Issue 3... -

6.2 Maintenance General safety information: With suitable isolation, repairs can be carried out with the trap in the pipeline. When reassembling, make sure that all joint faces are clean. Service being executed upon the valve can be undertaken with the Float in situe in a line or securely fastened in a vice. - Page 21 6.2.1 Pre-assembly of the main valve Holding the lever arm and float vertically with the float downward. Place the conical spring (16) in the box at the end of the lever arm, with the small diameter of the conical spring facing upward, place the ball (15) upon the top of the spring. Insert the pin (13).
- Page 22 6.2.3 Replacing the Air vent assembly Gain access to the internals by removal of the cover (2) by undoing the six ¾" UNF (4) nuts holding the cover in place. Then remove the air vent assembly (9) and the air vent tube (10). Put a little anti-seize on the thread of the new air vent assembly (9) together with the tube (10) preassembled, tighten following the guidance of the torque setting in the table.
- Page 23 6.2.4 How to clean or replace the strainer screen: Access to the strainer screen can be obtained by removing the strainer cap (6). Remove the strainer screen (7) and gasket (8). Fit a new or cleaned strainer screen into the recess in the cap (6). A new gasket (8) must always be fitted and the cap (6) screwed into the body and tighten to the recommended torque (170-190 Nm).
- Page 24 6.2.5 General notes Smear threads (both ends) of the studs (5) and also of items (6), (9) and (12) with with a suitable anti- seize compound, such as FUCHS PCB or ROCOL J166, taking care the compound does not come into contact with any sealing surfaces.
