  • Page 4: Operation

    3. Operation At start-up, since the ⑮float is down, the ⑦valve set is closed. In this state, air in the system and piping is discharged out through the ⑯air vent which is opened. When condensate flows into the product, the ⑮float lifts up and opens the ⑦valve set, and then discharges condensate.

  • Page 5: 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.

  • Page 6: Installation

    5. Installation 5.1 Piping example *Pipe size of the outlet side of the product should be large enough so that the discharged condensate flows without any resistance. Description Correct Incorrect If the product is installed close Regulating Regulating valve to a regulating valve, make valve sure to install the product at the inlet side of the regulating...
  • Page 7 Description Correct Incorrect Install the products for each device independently. 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 8: 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 9 Secure enough space for maintenance, inspections and repair as shown below. * Failure to follow this notice prevents maintenance, inspection and repair. *Common to 40A and 50A 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.

    5. To assemble, connect all the parts securely and tighten the bolts uniformly in diagonal order. * Failure to follow this notice may cause malfunction or outside leakage. 6. When repairing, do not use the parts other than the dedicated parts manufactured by Yoshitake. Do not modify the product.

    8．TSF-13,13F with Steam Lock Release（SLR） 8.1 What is SLR If you need the product with ⑱Steam Lock Release (SLR), please let us know when you purchase. It cannot be attached to the standard product later. Steam locking occurs when the pipe to the trap is filled with steam and the steam prevents condensate from flowing into the trap.
