Safety information, installation and maintenance Pressure
Before attempting any maintenance of the trap, consider what is or may have been in the pipeline. Ensure that any pressure is isolated upstream and downstream of the trap and safely vented to atmospheric pressure before attempting to maintain the trap. This is easily achieved by fitting Spirax Sarco depressurisation valves type DV (see separate literature for details). Do not assume that the system is depressurised even when a pressure gauge indicates zero. Temperature Allow time for temperature to normalise after isolation to avoid the danger of burns and consider whether protective clothing (including safety glasses) is required. Installation The air and gas trap must always be fitted with the inlet at the top so that the float mechanism is rising and falling in a vertical plane. The high point of the cover is provided with ½ " tapping for a balance pipe which is essential for satisfactory operation. From the tapping provided at the high point of the cover a balance pipe having a continuous rise must be fitted and connected into the space being drained. Maintenance How to fit the main valve assembly - Isolate, undo cover bolts, remove existing mechanism. - Using a little jointing paste on the thread and gasket, fit the new valve seat to the body. - Attach the support frame, and pivot frame to the body with assembly set screws, but do not tighten. - Fit the float arm to the pivot frame using the pin and by moving the complete assembly centre the valve head onto the seat orifice. - Hold the assembly firmly in place and tighten up set screws to the recommended tightening torque. - Check operation by raising and lowering the float several times making sure that the valve head is centring properly on the seat. - Make sure all joint faces are clean, apply a thin coating of jointing paste to seat threads. - Tighten cover bolts uniformly to the recommended tightening torque. Open up isolating valve slowly. Disposal The product is recyclable. No ecological hazard is anticipated with the disposal of this product providing due care is taken.
