Page 7 Operation Principles of air and condensate discharge: Air and Cold Condensate Discharge at Startup At startup, before steam is supplied, the system is cold and the air vent strip (bimetal) is contracted, holding the float off the orifice. This allows for the rapid discharge of air and cold condensate through the valve when steam is first supplied to the system.
Page 8 Specifications Caution Install properly and DO NOT use this product outside the recommended operating pressure, temperature and other specification ranges. Improper use may result in such hazards as damage to the product or malfunctions that may lead to serious accidents. Local regulations may restrict the use of this product to below the conditions quoted.
Page 9 Compatibility • Trap units S1NL/S1NH are compatible with TLV F46 and F32 connector units, trap stations (V1/V2/V1P/V2P Series) and QuickStation QS10/QS18. The connector unit name is indicated on the connector body.

Page 13 Periodically (at least biannually) the operation should also be checked by using diagnostic equipment such as a stethoscope, thermometer, TLV Pocket TrapMan or TLV TrapMan. If the product should fail, it may cause damage to piping and equipment, resulting in faulty or low quality products or losses due to steam leakage.
Page 14 Disassembly/Reassembly Warning NEVER apply direct heat to the float. The float may explode due to increased internal pressure, causing accidents leading to serious injury or damage to property and equipment. Caution When disassembling or removing the product, wait until the internal pressure equals atmospheric pressure and the surface of the product has cooled to room temperature.

Page 18 Instructions for Plug/Holder Disassembly and Reassembly The seal on the threaded plugs/holders found on TLV products is formed by a flat metal gasket. There are various installation orientations for the gaskets, such as horizontal, diagonal and downward, and the gasket may be pinched in the thread recesses during assembly.
Page 19 Troubleshooting Caution When disassembling or removing the product, wait until the internal pressure equals atmospheric pressure and the surface of the product has cooled to room temperature. Disassembling or removing the product when it is hot or under pressure may lead to discharge of fluids, causing burns, other injuries or damage.

Page 23 The options shown below are available for this product on request. Please compare with the product you received. Options for Area A (Screen Holder) With Blowdown Valve (TLV BD2) Caution Always wear eye protection and heat-resistant gloves when operating the blowdown valve.
Page 24 Note Avoid the use of excessive tightening torques, as threaded parts may become damaged. TLV Blowdown Valve: BD2 The BD2 Blowdown Valve, installed in the screen area of the body, uses the trap’s internal pressure to blow any condensate, steam, dirt or scale accumulated around the screen area out to the atmosphere.
Page 25 6 Gland Retainer Nut These models are not available in all regions. TLV Scale Removal Function: -TZ The -TZ Scale Removal Function, installed in the cover of the trap unit, uses a specially designed rod to remove dirt or scale accumulated in the orifice to prevent/eliminate blockage.
Page 26 Installation This product is fitted with an orifice scale removal unit that requires a certain amount of maintenance space for this operation. The recommended maintenance space (a = approx. 50 mm), measured from the ground (b) to the product, is shown in the figure to the right. Install flanged connector bodies horizontally only.
Page 27 Hold the gland case securely in place using a tool such as an adjustable wrench or an open-end wrench and slowly turn the removal rod back to the left until it will turn no further. The scale that had been clogging the orifice opening has now been removed and the trap is restored to normal operation.
