INSTALLATION AND MAINTENANCE INSTRUCTIONS
BALANCED PRESSURE THERMOSTATIC CLEAN STEAM TRAPS
TSS 7 –TSS 6
GENERAL
These instructions must be carefully read before any work involving products supplied by VALSTEAM ADCA
ENGINEERING S.A. is undertaken.
The installation procedure is a critical stage in a life of a steam trap and care should be taken to avoid damage
to the trap or equipment.
The TSS 7 and TSS 6 steam traps are specially designed to remove air and condensate from clean and pure
steam systems. They give their maximum performance only when the equipment associated with them is
correctly sized and installed in accordance with our recommendations.
Note:
Current regional safety regulations should be take in to account and followed, while doing the installation and
maintenance work.
Handling, installation and maintenance work must be carried out by trained personnel. A supervisor must follow
and check all activities.
For the problems that cannot be solve with the help of this instructions, please contact the supplier or the
manufacturer.
The manufacturer reserves the right to change the design and material of this product without notice.
- If malfunction of any other equipment or system operation failure may result in a dangerous overpressure, over
temperature or even vacuum condition, a safety device must be included in the system to prevent such
situations.
- At start up, the presence of small particles in the fluid (dirt, scale, weld splatters, etc) may cause an imperfect
closure of the seat. If this occurs, proceed to an accurate cleaning.
- Do not touch the equipment without appropriate protection during working operation because it may conduct
heat if the used fluid is at high temperature.
- Before starting maintenance be sure that the equipment is not pressurized or hot. Even if upstream and
downstream isolating valves have been closed care should be taken since fluid under pressure may be trapped
between them.
- Before removing the cover of the equipment make sure that its temperature has decreased to ambient
levels, otherwise damage of the thermostatic element may occur, due to thermal chock.
- The equipments must be used within the working temperature and pressure limits laid down for them, otherwise
they may fail (refer to nameplate and/or IS- Information Sheet).
- Manual handling of products may present a risk of injury. You are advised to assess the risks taking into
account the task, the individual, the load and the working environment.
- Before starting work ensure that you have suitable tools and/or consumables available. Use only genuine ADCA
replacement parts.
- Do not remove the nameplate attached to the equipment. Serial number and other useful information is
stamped on it.
- During the assembly work, apply protective measures against dirt.
- The equipment should be carefully handled, to prevent any damage on the machined surfaces.
- Correct installation of the equipment is full responsibility of the contractor.
- Steam traps are designed to be applied in places protected from exposure to weather.
- We recommend special constructions or protective measures for applications on the outside or in adverse
environments like corrosion-promoting conditions (sea water, chemical vapors, etc).

CLEANING AND PACKING
This equipment is packed by proper machine with a special film used by food industry.
These equipments are degreased and cleaned ultrasonically.
TRANSPORT AND STORAGE
- Handling and lifting of materials should be made with adequate equipments.
- The steam traps and equipments should be protected from impacts and forces during transportation and
storage.
- The manufacturer doesn’t assume the responsibility of damaged equipments due to inappropriate handling
during the transportation and storage.
INSTALLATION
- Account for over pressure conditions, according with the local laws or standards.
- Steam traps must not be used with other purpose than the one they were built for (e.g. climbing aids or as
connecting points for lifting gear).
- For the problems that cannot be solve with the help of this instructions, please contact the supplier or the
manufacturer.
Installation area requirements:
The installation area should have easy access and provide enough space for maintenance and removing
operations.
In order to allow installation and maintenance work without emptying the system, stop valves should be installed
upstream and downstream of the steam trap.
If the system cannot be stopped for maintenance it is recommended that isolating valves are installed
upstream and downstream of the steam trap together with a by-pass manual regulating valve. The
process can be then controlled manually during the steam trap maintenance. The by-pass must be kept
close during the normal operation.
Procedure:
Prior to install check that the product is suitable for the intended application: materials and
pressure/temperature ratings.
Before installing remove plastic covers placed on flanges or connection ends. The equipment has an arrow or
Inlet/Outlet designations. Be sure that it will be installed on the appropriate direction.
Install the steam trap in the point of the system, where the condensate tends to collect. It must be installed in
the vertical position.
Take care with jointing material to ensure that none may be permitted to block or enter the trap.
The steam trap is designed for sanitary service and it is assumed that the fluid is clean and filtrated. If not, a
protection strainer should be used upstream of the steam trap.
Do not over-tighten clamps because that can damage the gasket.

External stresses that may be induced by the system due to pipe expansion, etc, can affect this product. The
necessary precautions are recommended during the systems design and equipment assembly.
The steam trap pipework should be properly supported and free from strain and it should not be subjected to
undue surges of pressure. The start-up condition should be considered.
START UP
- Current regional safety regulations should be take in to account and followed.
- Protective insulation and warning notice may be required.
- Until the start up of an existing or a new plant, the following must be checked:
- All works are completed.
- The steam trap is correctly installed.
- All the necessary safety devices have been installed.
- At start up, the presence of small particles in the fluid (dirt, scale, weld splatters, joint particles, remains
of Teflon tape, etc) may cause an imperfect closure of the seat. If this occurs, proceed to an accurate
cleaning.
Periodical checking:
24 hours after the start up, it is recommended to check pipe connections for leaks and retighten the connections
if necessary.
MAINTENANCE
We recommend the steam traps to be serviced as necessary. Steam traps should be checked periodically (at
least yearly), to verify if they are operating correctly and to clean the internal parts and strainer screen (if any).
When reassembling make sure that all gasket faces are clean and always use a new gasket.
Lubrication must be avoided for oxygen service. When it’s necessary, only the lubricants recommended by the
manufacture should be use.
Maintenance should proceed as follows:
1. Isolation valves should be closed and the pressure and temperature must be atmospheric.
2. Remove sanitary clamps or other type of connection used.
3. Execute the maintenance work.
4. Replace and tighten the clamps. (Don’t forget to substitute the gasket).
5. Consider the start up conditions.
