- 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.
- 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.
- When connecting flanges, the bolts should be mounted from the counter flange side with the hexagon nuts from
the trap side and it must exist a perfect match between the connection flanges.
- Tighten flange connection bolts uniformly in a diagonal sequence.
- 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).
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.
•The installation area should have the necessary firing system to prevent damage of the equipment due to over
temperature/pressure cause by fire.
•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.
•Take care with jointing material to ensure that none may be permitted to block or enter the trap.
•In case of using Teflon tape (for screwed connections), avoid rolling it till the edge, because it can get cut and
migrate to the trap interior, blocking or causing a defective sealing.
•Install the steam trap in the point of the system, where the condensate tends to collect.
•An ADCA pipeline strainer should be installed upstream of the trap to protect from dirt which could damage the
steam trap or cause mal-functioning. The strainer must be installed with the sieve sideways, if the medium is
steam, to prevent the collection of condensate.
•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. Tighten cover
bolts uniformly in a diagonal sequence.
•Maintenance should proceed as follows:
1. Isolation valves should be closed and the pressure and temperature must be atmospheric.
2. Remove the type of connections used.
3. Execute the maintenance work.
4. Replace and tighten the connections. (Don’t forget to substitute the gasket).
5. Consider the start up conditions.
TROUBLESHOOTING
