TLV JH7.5R-X inline repairable free float steam traps with thermostatic air vent (X-element) are suitable for a wide range of applications with small-to-large capacities and pressures up to 3.2 MPaG (450 psig), such as heat exchangers, process heaters, and coils. The traps discharge condensate continuously and automatically, at a temperature slightly lower than saturation temperature.

DANGER

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.

WARNING

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.

Proper Installation

• Installation, inspection, maintenance, repairs, disassembly, adjustment and valve opening/closing should be carried out only by trained maintenance personnel.
• 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. Install the steam trap within the allowable inclination, as shown below. Also make sure that the arrow mark on the body corresponds with the direction of flow.

4. 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.
5. Support the pipes properly within 800 mm (2.5 ft) on either side of the trap.
6. 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.
7. Install a check valve at the trap outlet whenever more than one trap is connected to the condensate collection pipeline.

Piping Arrangement

Requirement
Install a catchpot with the proper diameter.
Make sure the flow of condensate is not obstructed.
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.
When installing on the blind end, make sure nothing obstructs the flow of condensate.

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?

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.

Parts Inspection Procedure

• Body, Cover(s): Check inside for damage, dirt, grease, oil film, rust or scale
• Gaskets: Check for warping or damage
• X-element: Check for damage
• Screen(s): Check for clogging, corrosion or damage
• Float: Check for deformation, damage, oil film or water inside
• Air Vent Valve Seat, Orifice: Check for rust, scale, oil film, wear or damage

Operational Check

A visual inspection can be carried out to aid in determining the necessity for immediate maintenance or repair, if the trap is open to atmosphere.

• Normal: Condensate is discharged continuously with flash steam and the sound of flow can be heard. If there is very little condensate, there is almost no sound of flow.
• Blocked: No condensate is discharged. The trap is quiet and makes no noise, and the surface temperature of the trap is low.
• Blowing: Live steam continually flows from the outlet and there is a continuous metallic sound.
• Steam Leakage: Live steam is discharged through the trap outlet together with the condensate and there is a high-pitched sound.

Troubleshooting

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
	X-element is damaged	Replace the X-element
	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 orifice 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 X-element is damaged, or clogged with rust or scale	Clean or replace the X-element
