3. Installation Notes Before conducting any maintenance activities observe the 'Safety information' in Section 1. Referring to the Installation and Maintenance Instructions, name-plate, and Technical Information Sheet, check that the product is suitable for its intended use. Warnings The gaskets contained in this product incorporate a thin stainless steel support ring, which may cause physical injury if not handled and disposed of carefully. - Page 9 Heat exchanger Liquid out / in FTC80 Fig. 2 Typical installation of FTC80 Condensate 4. Commissioning Commissioning with particular reference to venting air It can take several hours or even days to bring a new system to normal operating pressure and temperature.

5.3 Correct sizing It is important that the FTC80 is correctly sized to the running load of the plant being drained. See the following Technical Information Sheets for full details on capacities: TI-IBR16-33IN for the ASTM body. If the trap is undersized then it will still attempt to operate correctly however condensate will back up. - Page 11 Incorrectly sized pipework will lead to rapid erosion of the pipework and / or product and may also generate excessive backpressure on the trap. Clearly DN40 and DN50 (1½" and 2") FTC80's condensate discharge line will need to be significantly larger than 40 mm or 50 mm when high pressures and high flowrates are involved.

Warnings The gaskets contained in this product incorporate a thin stainless steel support ring, which may cause physical injury if not handled and disposed of carefully. The strainer screen is manufactured from sheared perforated sheet which may cause physical injury if not handled and disposed of carefully. - Page 13 Fig. 4 Strainer screen Install bolts hand tight then "snug-up" to 15 N m to 30 N m but not to exceed 20% of the target torque. Check flange gap for uniformity. Tighten to 20% to 30% of target torque. Check flange gap for uniformity. Tighten to 50% to 70% of target torque.
- Page 14 6.4 How to access the mechanism assembly To gain access to the mechanism assembly (13) the cover (2) needs to be removed. For this, and any servicing, the trap may remain in the pipeline. Ensure the trap is depressurised (see 'Section 6.1 - General information') Unscrew the 14 off cover nuts (5) and remove the cover (2) and cover gasket (3).

- Page 17 6.5 Servicing the mechanism assembly (Mechanism seat (15) and ball head (16)) Ensure the trap is depressurised (see 'Section 6.1 - General information'). Follow the instructions under Section 6.4 to access and remove the mechanism assembly (13 and 14). Once removed, the mechanism assembly (13) is easily disassembled by removing each spring clip (20) at the end of each pivot pin (21).
