Page 4: Maximum Continuous Discharge Capacity
4. Maximum Continuous Discharge Capacity 1. Discharging capacity of the steam trap differs by working differential pressure, that is, difference between inlet pressure and outlet pressure (back pressure). In selecting discharge capacity, consider outlet pressure. If inlet pressure is 0.5 MPa and outlet pressure is 0.2 MPa, discharge capacity is of working differential pressure of 0.3 MPa. -

The diameter of collecting pipe shall be more than summation of sectional areas of discharge pipes. In addition, install check valves for back flow prevention. For condensate recovery, connect the discharge pipe to the upper part of collecting pipe.

Page 7: Precaution For Installation
5.2 Precaution for installation Warning 1. In order to discharge condensate to the atmosphere, lead the outlet to a safe place where there is no possibility of physical damage even if condensate blows out. * There are risks of scalding or injury when the condensate blows out. Caution 1. -
Page 8: Operating Procedure
7. Slope the piping and place the product at as a low position as possible in order to make condensate flow into the product by its own weight. 8. To install the product in a main steam pipe, provide a drip leg at the inlet side of the product. 9. -
