3. Installation
Note:
Before actioning any installation observe the 'Safety information' in Section 1.
Warning
The cover gasket contains a thin stainless steel support ring, which may cause
physical injury if not handled and disposed of carefully.
Referring to the Installation and Maintenance Instructions, name-plate, and Technical
Information Sheet, check that the product is suitable for its intended use.
3.1
Check materials, pressure and temperature and their maximum values. If the maximum
operating limit of the product is lower than that of the system in which it is being fitted,
ensure that a safety device is included in the system to prevent overpressurisation.
3.2
Determine the correct installation situation and direction of fluid flow – please be aware
that the flow direction is not the same for all FT trap types or sizes. However the flow
direction will be clearly marked on the trap body.
3.3
Remove protection covers from all connections and protective film from all name-plates,
where appropriate, before installation on steam or other high temperature applications.
3.4
The trap must be fitted with the float arm in a horizontal plane so that it rises and falls
vertically. Note: The trap can be visually checked for its correct orientation by reading
the writing on the body, cover, and name-plate. If installed correctly the writing will be
seen to be displayed the correct way up.
3.5
The trap should be fitted below the outlet of the steam system, with a small drop leg
immediately proceeding the trap, typically 150 mm (6") see Figure 5. If no drop leg is
allowed for then it may be possible (under low load conditions) for steam to flow over
the condensate in the bottom of the pipe and reach the trap.
