loss damage or consequential damage to property or persons caused by explosions,
poisoning or other accidents due to use with hazardous fluids.
This free float gas trap (drain trap) uses a precision-polished float and three-point
support for the valve body. With no hinges or levers, the trap continuously
discharges condensate, preventing it from collecting. The three-point seating for the
valve body supports the precision-ground float securely at three points and ensures
a high degree of sealing for even minute quantities of condensate. The trap can also
be disassembled and reassembled while still installed in the piping. This results in
considerable time savings and facilitates repair and maintenance.
The outstanding features of the precision-ground float and 3-point valve body
support, combined with a mechanism that has a proven record of success, make it
suitable for condensate discharge from a variety of gas systems.
If detailed instructions for special order specifications or options not contained in this
manual are required, please contact 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.

CAUTION
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 vertical?
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?
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

The Need for a Pressure-balancing Line
In principle, drain traps automatically and continuously discharge condensate that
flows in. However, air or gas caught in the piping or trap body may obstruct
condensate flow. This phenomenon is called “air binding”. Air binding occurs more
often in piping with long horizontal lengths, smaller diameters or multiple bends. To
prevent air binding and ensure air or gas can be displaced by incoming condensate,
a pressure-balancing line should be installed between the trap cover and the dry
portion of the receiver tank.
Since the SS1VG is installed vertically, a balancing line is not generally required.
However, to prevent air binding, follow the instructions below, using inlet piping with
a minimum nominal diameter of 15 mm (1/2in).
1) The inlet piping must be straight, vertical and as short as possible (see fig. 1).
2) If the point of condensate discharge requires horizontal piping, it should be
kept as short as possible, no more than 200 mm (8 in) long, then arrange
vertical inlet piping (see fig. 2).
3) If a longer horizontal length of piping is unavoidable, then a pressure-
balancing line must be installed (see fig. 3).

Secondary Side Precautions
Take measures to ensure the proper handling, such as recovery or
dilution, of hazardous fluids discharged at product outlets. Outflow of
fluid or fluid leaks may lead to hazards such as flammable conditions or
corrosion, which may result in injury, fires, damage or other accidents.
CAUTION
Be sure to take precautions on the secondary side when using flammable, toxic or
other hazardous gases.
Sample precautionary procedures:
1. Flare method
2. Collection in a seal pot
3. Collection in a sealed container

Maintenance
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.
CAUTION
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 or burns
or other injury due to malfunction or the discharge of fluids.
CAUTION
Operational Check
A visual inspection of the following items should be done on a daily basis to
determine whether the trap is operating properly or has failed. Periodically (at least
biannually) the operation should also be checked by using diagnostic equipment,
such as a stethoscope or thermometer.
If the trap should fail, it may cause damage to piping and equipment, resulting in
faulty or low quality products or losses due to air leakage.
Normal
:
Condensate is discharged continuously and the sound of
flow can be heard. If there is very little condensate, there
is almost no sound of flow.
Blocked (Discharge Impossible)
:
No condensate is discharged and no sound is made.
Blowing
:
Air or gas continually flows from the outlet and there is a
continuous metallic sound.
Air or Gas Leakage*
:
Air or gas is discharged through the trap outlet together
with condensate, accompanied by a high-pitched sound.
* The SS1VG –M with metal valve seat has a minimum condensate load requirement to ensure
proper sealing (see “Specifications”).
