Determine the correct installation situation and direction of fluid flow. Spirax Sarco products are not intended to withstand external stresses that may be induced by any system to which they are fitted. It is the responsibility of the installer to consider these stresses and take adequate precautions to minimise them.
1.9 Tools and consumables Before starting work ensure that you have suitable tools and/or consumables available. Use only genuine Spirax Sarco replacement parts. 1.10 Protective clothing Consider whether you and/or others in the vicinity require any protective clothing to protect against the hazards of, for example, chemicals, high/low temperature, radiation, noise, falling objects, and dangers to eyes and face.

225 °C (437 °F) Minimum operating temperature -20 °C (-4 °F) Note: For lower operating temperatures consult Spirax Sarco. Designed for a maximum cold hydraulic test pressure of: 37.5 bar g (544 psi g) PMX - Maximum differential pressure The maximum differential pressure depends on the specific gravity of the liquid being drained.
Ensure adequate space is left to remove the body from the cover for maintenance. Minimum withdrawal distance distance for the CAS14 ½" and ¾" is 135 mm (5.6") for the 1" it is 145 mm (5.8"). S6 separator Fig 3616 Fig.
4. Commissioning After installation or maintenance ensure that the system is fully functioning. Carry out tests on any alarms or protective devices. 5. Operation The compressed air ball float drain trap is a continuous discharge trap, removing condensate the instant it forms.
