TLV JH5RL-B inline repairable free float steam trap with thermostatic bimetal air vent is suitable for a wide range of applications with small-to-large capacities and pressures up to 10 MPaG (1500 psig), such as all kinds of heat exchangers, process heaters and coils. The trap discharges condensate continuously and automatically, at a temperature slightly lower than saturation temperature.

WARNING

NEVER apply direct heat to the float. The float may explode due to increased internal pressure, causing accidents leading to serious injury or property and equipment damage.

DANGER

To avoid malfunctions, product damage, accidents or serious injury install properly and DO NOT use this product outside the specification range. Local regulations may restrict the use of this product to below the conditions quoted.

Proper Installation

• Installation, inspection, maintenance, repairs, disassembly, adjustment and valve opening/closing should be carried out only by trained maintenance personnel.
• Use the eyebolts for removing the cover only; DO NOT use the eyebolts for hoisting the product.
• Take measures to prevent people from coming into direct contact with product outlets.
• Install for use under conditions in which no freeze-up will occur.
• Install for use under conditions in which no water hammer will occur.

1. Before installation, be sure to remove all protective seals.
2. Before installing the trap, blow out the inlet piping to remove all dirt and oil.
3. When hoisting the product, hang the rope around the inlet/outlet as close to the body as possible.
4. Install the steam trap within the allowable inclination. Also make sure that the arrow mark on the body corresponds with the direction of flow.
5. Install the trap in the lowest part of the pipeline or equipment so the condensate flows naturally into the trap by gravity. The inlet pipe should be as short and have as few bends as possible.
6. Support the pipes properly within 800 mm (2.5 ft) on either side of the trap.
7. Install a bypass valve to discharge condensate, and inlet and outlet valves to isolate the trap in the event of trap failure or when performing maintenance.
8. Install a check valve at the trap outlet whenever more than one trap is connected to the condensate collection pipeline.
9. The use of unions is recommended to facilitate connection and disconnection of screwed models.

Piping Arrangement

Requirement	Correct	Incorrect
Install a catchpot with the proper diameter.		Diameter is too small.
Make sure the flow of condensate is not obstructed.		Diameter is too small and inlet protrudes into pipe.
To prevent rust and scale from flowing into the trap, connect the inlet pipe 25-50 mm (1-2 in) above the base of the T-pipe.		Rust and scale flow into the trap with the condensate.
When installing on the blind end, make sure nothing obstructs the flow of condensate.		Condensate collects in the pipe.

Check to make sure that the pipes connected to the trap have been installed properly:

1. Is the pipe diameter suitable?
2. Has the trap been installed within the allowable inclination and with the arrow on the body pointing in the direction of flow?
3. Has sufficient space been secured for maintenance?
4. Have maintenance valves been installed at the inlet and outlet? If the outlet is subject to back pressure, has a check valve been installed?
5. Is the inlet pipe as short as possible, with as few bends as possible, and installed so that the condensate will flow naturally down into the trap?
6. Has the piping work been done with the proper methods?

Inspection and Maintenance

Operational inspections should be performed at least twice per year, or as called for by trap operating conditions. Steam trap failure may result in temperature drop in the equipment, poor product quality or losses due to steam leakage.

WARNING

Before attempting to open the trap, close the inlet and outlet isolation valves and wait until the trap has cooled completely. Failure to do so may result in burns.

Parts Inspection Procedure

Part	Inspection
Body, Cover(s)	Check inside for damage, dirt, grease, oil film, rust or scale
Gaskets	Check for warping or damage
Bimetal Plate	Check for damage
Air Vent Valve (and Seat)	Check for damage
Screen(s)	Check for clogging, corrosion or damage
Float	Check for deformation, damage, oil film or water inside
Orifice Opening	Check for rust, scale, oil film, wear or damage

Troubleshooting

If the expected performance is unachievable after installation of the steam trap, check the following points for appropriate corrective measures.

Problem	Cause	Remedy
No condensate is discharged (blocked) or discharge is poor	Float is damaged or filled with condensate	Replace the float
	Orifice, screen or piping are clogged with rust or scale	Clean
	The bimetal is damaged	Replace with new bimetal
	The trap operating pressure exceeds the maximum specified pressure, or there is insufficient pressure differential between the trap inlet and outlet	Compare specifications and actual operating conditions
	Steam locking has occurred	Blowdown through the bypass or close the trap inlet valve and allow the trap to cool
Steam is discharged or leaks from the trap outlet (blowing) (steam leakage)	Rust and scale have accumulated around the valve seat or under the float	Clean
	Orifice is damaged	Replace with new orifice
	Float is deformed or coated with scale	Clean or replace the float
	Trap is installed above the maximum allowable inclination angle	Correct the installation
	Vibration of trap occurs	Lengthen inlet piping, then fasten it securely
	The bimetal air vent valve surface and/or the air vent valve seat has a build-up or is scratched	Clean or replace with new bimetal and/or air vent valve seat
