IM-P602-12 ST Issue 44
1.6 The system
Consider the effect on the complete system of the work proposed. Will any proposed
action (e.g. closing isolation valves, electrical isolation) put any other part of the
system or any personnel at risk?
Dangers might include isolation of vents or protective devices or the rendering
ineffective of controls or alarms. Ensure isolation valves are turned on and off in a
gradual way to avoid system shocks.
1.7 Pressure systems
Ensure that any pressure is isolated and safely vented to atmospheric pressure.
Consider double isolation (double block and bleed) and the locking or labelling of
closed valves. Do not assume that the system has depressurised even when the
pressure gauge indicates zero.

3. Installation
Note: Before actioning any installation observe the 'Safety information' in Section 1.
Refering to the Installation and Maintenance Instructions, name-plate and Technical
Information Sheet, check that the product is suitable for the intended installation.
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 the direction of fluid flow.
3.3 Remove protective covers from all connections and the protective film from all
name-plates, where appropriate, before installation on steam or other high
temperature applications.
Installation notes:
- Suitable isolation valves must be installed to allow for safe maintenance / replacement.
- If the trap is to discharge to atmosphere ensure it is to a safe place, the discharging
fluid may be at a temperature of 100°C (212°F).
- The trap must be fitted with the float arm in a horizontal plane so that it rises and
falls vertically, therefore the arrow on the name-plate must point downwards.
- Unless specified, traps will be supplied with horizontal connections and
with right to left flow (R-L). Traps can be supplied with vertical connections with
flow from top to bottom or horizontal connections with flow from right to left (R-L) or
left to right (L-R).
- The connection orientation can be changed on site by undoing the four cover bolts and
moving the cover to the preferred orientation. A new gasket must always be fitted.
- Minimum withdrawal distance to remove cover is 120 mm (4.75").
- The FTC32 can be lagged in cold and exposed situations.
Installation of the manually adjustable needle valve (SLR - steam lock release feature)
3.4 The manually adjustable needle valve is fitted to all float traps where a suffix 'C' is
hard stamped on the name-plate e.g. FTC32-10C. 'C' = Combined steam lock release
feature and thermostatic air vent.
3.5 Check if the application requires the manually adjustable needle valve for correct
operation. The manually adjustable needle valve should only be used to prevent 'steam
locking' and therefore is designed to pass only a small amount of steam.
3.6 The manually adjustable needle valve will be dispatched, pre-set to a partial bleed
condition. The unit should be screwed clockwise to close and anticlockwise to open.
When required the SLR should be used as a controlled continuous bleed, it is not
recommended that the SLR be left in the fully open condition as this may lead to
premature trap failure and more frequent maintenance schedules.
Warning
The cover gasket contains a thin stainless steel support ring which may cause physical
injury if not handled and disposed of carefully.
Please consult Spirax Sarco should further information be required.

IM-P602-12 ST Issue 410
4. Commissioning
After installation or maintenance ensure that the system is fully functioning. Carry out tests
on any alarms or protective devices.
5. Operation
The float trap is a continuous discharge trap, removing condensate the instant it forms.
On start-up, the thermostatic air vent allows air to bypass the main valve preventing the system
air binding. Hot condensate will close the air vent tightly, but as soon as it enters the main
chamber of the trap, the float rises and the lever mechanism attached to it opens the main
valve - keeping the system drained of condensate at all times. When steam arrives, the float
drops and closes the main valve. Float traps are renown for their high start-up load handling
capability, clean tight shut-off and resistance to waterhammer and vibration.
6. Maintenance
Note: Before actioning any maintenance program 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.
6.1 General information:
Before undertaking any maintenance on the trap it must be isolated from both the
supply line and return line and any pressure allowed to safely normalise to atmosphere.
The trap should then be allowed to cool. It is recommended that new gaskets and 'O'
rings are used when ever maintenance is undertaken. When reassembling, ensure
that all joint faces are clean. On standard traps (without a check valve) a simple ferrule
is fitted in place of the check valve. This must always be replaced before assembly.
6.2 How to fit the main valve assembly:
- Undo the body bolts (3) and remove the body (1) and gasket (4).
- With the body (1) securely held in a vice remove the pivot pin (13) and float assembly (8).
- Undo the three assembly screws (7) and remove the seat (5).
- Fit new 'O' ring (6) and seat (5).
- Tighten the screws (7) to the recommended torque - see Table 1.
- Refit the pivot pin (13) and float assembly (8).
- Replace the body (1) (using a new gasket 4) and tighten the body bolts (3) to the
recommended torque (see Table 1), ensuring the gasket faces are clean and undamaged.
