TLV SS1VA Instruction Manual
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.
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.
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 damag e 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
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
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.
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
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.
CAUTION
Installation, inspection, maintenance, repairs, disassembly, adjustment
and valve opening/closing should be carried out only by trained
maintenance personnel.

Thank you for purchasing the TLV free float drain trap for air and
inert gases.
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. Before beginning
installation or maintenance, please read this manual to ensure
correct usage of the product.
This instruction manual is needed not only for installation, but for subsequent
troubleshooting. Please keep it in a safe place for future reference.
The contents of this manual are subject to change without notice.
1. Safety Considerations
Free Float Drain Trap SS1VA
between the equipment and the product is unavoidable, the horizontal piping must be
kept as short as possible. If it exceeds 200 mm (8 in), a pressure-balancing line must
be installed (see right).
5. The product must be installed vertically, inclined no more than 5° horizontally and
front-to-back.
6. Install a condensate outlet valve and outlet piping.
7. Open the inlet and outlet valves, make sure that the product functions properly.
5. Inspection and Maintenance
Operational Check: A visual inspection of the following items should be done on a
daily basis to determine whether the product 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 product should fail, it may cause damage to piping and equipment, resulting in
faulty or low quality products or losses due to air or gas leakage.
When parts have been removed, or during periodic inspections, use the table to the
right to inspect the parts and replace any that are found to be defective.
6. Disassembly / Reassembly
Use the following procedures to remove components. Use the same procedures in
reverse to reassemble. If drawings or other special documentation were supplied for the
product, any torque given there takes precedence over values shown here.
2. Specifications
Refer to the product nameplate for detailed specifications.
Minimum Required Condensate Load: For SS1VA-M with a metal valve seat, a minimum
required condensate load of 0.5 kg/h (1 lb/h) is necessary to maintain a liquid seal. There is a
chance of air/gas leak if the condensate load falls below this rate.
3. Configuration
7. Troubleshooting
When the product fails to operate properly, use the following table to locate the cause.
(1 Nm 10 kgcm)
4. Proper Installation
1. Before installation, be sure to remove all
protective seals.
2. Before installing the product, open the inlet
valve and blow out the piping to remove any
piping scraps, dirt and oil. Close the inlet
valve after blowdown.
3. Install the product so the arrow on the body
is pointing in the direction of flow.
4. To prevent air binding, inlet piping must be
straight, vertical, as short as possible and
with a minimum nominal diameter of 15 mm (1/2 in). If a length of horizontal piping
* SS1VA-M with metal valve seat requires a minimum condensate load of 0.5 kg/h (1 lb/h) to
prevent any air/gas leak
