Free Float Drain Trap
JAH5RA-R
JAH7RA-R
Introduction
Thank you for purchasing the TLV free float drain trap.
This product has been thoroughly inspected before being shipped from the factory.
When the product is delivered, before doing anything else, check the specifications
and external appearance to make sure nothing is out of the ordinary. Also be sure to
read this manual carefully before use and follow the instructions to be sure of using
the product properly.
This product is designed, manufactured, and inspected for use with air, inert
gases and condensate. Do not use for toxic, flammable or otherwise
hazardous fluids. Hereafter in this manual, the words “gas” and “gases”
should be read as “inert gas” and “inert gases”.
This free float drain trap employs a precision-ground float and three-point seat. With no
hinges or levers, the trap automatically and continuously discharges condensate as it
forms in the air/gas system, preventing it from backing up in the system. The threepoint seat supports the precision-ground float at three points, ensuring an air-tight seal
even under extremely low condensate loads. This free float drain trap is also inline
repairable, facilitating repair and maintenance, resulting in considerable time savings.
If detailed instructions for special order specifications or options not contained in this
manual are required, please contact TLV for full details.
This instruction manual is intended for use with the model(s) listed on the front cover.
It is necessary not only for installation but for subsequent maintenance,
disassembly/reassembly and troubleshooting. Please keep it in a safe place for
future reference.

Safety Considerations
Read this section carefully before use and be sure to follow the instructions.
Installation, inspection, maintenance, repairs, disassembly, adjustment and valve
opening/closing should be carried out only by trained maintenance personnel.
The precautions listed in this manual are designed to ensure safety and prevent
equipment damage and personal injury. For situations that may occur as a result
of erroneous handling, three different types of cautionary items are used to
indicate the degree of urgency and the scale of potential damage and danger:
DANGER, WARNING and CAUTION.
The three types of cautionary items above are very important for safety: be sure to
observe all of them as they relate to installation, use, maintenance, and repair.
Furthermore, TLV accepts no responsibility for any accidents or damage occurring
as a result of failure to observe these precautions.

WARNING
DO NOT use for toxic, flammable or otherwise hazardous
fluids.
This product is a drain trap that discharges condensate from air or
inert gas systems. Use only for air or inert gas. This product is for
intended use only. Improper use may result in such hazards as
damage to the product or malfunctions that may lead to serious
accidents.
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
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.
DO NOT use this product in excess of the maximum operating
pressure differential.
Such use could make discharge impossible (blocked).
Use hoisting equipment for heavy objects (weighing
approximately 20 kg (44 lb) or more).
Failure to do so may result in back strain or other injury if the object
should fall.
Take measures to prevent people from coming into direct
contact with product outlets.
Failure to do so may result in burns or other injury from the
discharge of fluids.
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.
Be sure to use only the recommended components when
repairing the product, and NEVER attempt to modify the
product in any way.
Failure to observe these precautions may result in damage to the
product and burns or other injury due to malfunction or the
discharge of fluids.
Use only under conditions in which no freeze-up will occur.
Freezing may damage the product, leading to fluid discharge, which
may cause burns or other injury.
Use only under conditions in which no water hammer will occur.
The impact of water hammer may damage the product, leading to
fluid discharge, which may cause burns or other injury.

product is a drain trap that discharges condensate from air or inert gas
systems. Use only for air or inert gas. This product is for intended use
only. Improper use may result in such hazardous as damage to the

discharge, which may cause burns or other injury.
CAUTION
Requirement
Correct
Incorrect
Install 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 interior.
To prevent rust and scale
from flowing into the trap,
the inlet pipe should be
connected 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 the flow of
condensate is not
obstructed.
Condensate collects in the pipe.
Checking the Piping
Check to make sure that the pipes to be connected to the trap have been installed
properly.
1. Is the pipe diameter suitable?
2. Is the piping where the trap is to be installed horizontal?
3. Has sufficient space been secured for maintenance?
4. Have isolation 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 the liquid will flow naturally down into the trap?
6. Has the piping work been done correctly, as shown in the figures below?

Operation
1. Start-up
At start-up, the float is sealing the valve seat.
NOTE: If there is no condensate in the trap body,
prime with some water through the pressurebalancing line before startup.(Do this after
installation and disassembly/ inspection)
Pressurebalancing Line
Valve Seat
2. Condensate Discharge
As air/gas is supplied, condensate flow begins. The
rising condensate level causes the float to rise due to
buoyancy, opening the valve seat and allowing
condensate to be discharged.
3. Closed Position
When the condensate flow rate decreases, the float
falls, closing off the valve seat opening. A water seal is
maintained at all times over the valve seat to prevent
air/gas leakage.
Air/Gas Condensate
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 which may lead to serious accidents. Local regulations
may restrict the use of this product to below the conditions quoted.
CAUTION
DO NOT use this product in excess of the maximum operating pressure
differential; such use could make discharge impossible (blocked).
CAUTION
Use only under conditions in which no freeze-up will occur. Freezing
may damage the product, leading to fluid discharge, which may cause
burns or other injury.
