INSTALLATION AND MAINTENANCE INSTRUCTIONS
FLOAT & THERMOSTATIC STEAM TRAPS
FLT17
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.
Warning!
- At start up, the presence of small particles in the water (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.
- 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).
- Do not remove the nameplate attached to the equipment. Serial number and other useful information is stamped
on it.
INSTALLATION
- Before to install 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 with the
float lever in horizontal plane, so that it rises and falls vertically. An ADCA strainer should be installed upstream of
the trap.

CE Marking:
This product has been designed for use on water and steam
which are in Group 2 of the European PED-Pressure Equipment
Directive in use and it complies with those requirements.
The product fall within category SEP and must not be CE marked.
Installation area requirements:
•The installation area should have easy access and provide enough space for maintenance and removing
operations.
•The installation area should have the necessary firing system to prevent damage of the equipment due to over
temperature/pressure cause by fire.
MAINTENANCE
•We recommend that the float steam traps are serviced as necessary. Steam traps should be checked
periodically (at least yearly), to verify that they are operating correctly and to clean the internal parts and 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.
•For further information refer to the relevant FLT17 brochure or consult our Sales Office.
TROUBLESHOOTING
- If the malfunctions cannot be solved with the help of the following chart, please consult the manufacturer.
- Some of these faults may only occur in some models.
TROUBLE SHOOTING CHART
