1. General safety information
Safe operation of this product can only be guaranteed if it is properly installed,
commissioned, used and maintained by qualified personnel (see Section 1.11) in
compliance with the operating instructions. General installation and safety instructions
for pipeline and plant construction, as well as the proper use of tools and safety
equipment must also be complied with.
1.1 Intended use
Referring to the Installation and Maintenance Instructions, name-plate and Technical
Information Sheet, check that the product is suitable for the intended use/application.
This product complies with the requirements of the Indian Boiler Regulations, 1950.
i) This product has been specifically designed for use on steam, air or water/
condensate. The products’ use on other fluids may be possible but, if this is
contemplated, Spirax Sarco should be contacted to confirm the suitability of
the product for the application being considered.
ii) Check material suitability, pressure and temperature and their maximum and
minimum values. If the maximum operating limits of the product are lower than
those of the system in which it is being fitted, or if malfunction of the product could
result in a dangerous overpressure or overtemperature occurrence, ensure a safety
device is included in the system to prevent such over-limit situations.
iii) Determine the correct installation situation and direction of fluid flow.
iv) Spirax Sarco products are not intended to withstand external stresses that may
be induced by any system to which they are fitted. It is the responsibility of the
installer to consider these stresses and take adequate precautions to minimise
them.
v) Remove protection covers from all connections and protective film from all
name-plates, where appropriate, before installation on steam or other high
temperature applications.
1.2 Access
Ensure safe access and if necessary a safe working platform (suitably guarded)
before attempting to work on the product. Arrange suitable lifting gear if required.
1.3 Lighting
Ensure adequate lighting, particularly where detailed or intricate work is required.
1.4 Hazardous liquids or gases in the pipeline
Consider what is in the pipeline or what may have been in the pipeline at some
previous time. Consider: flammable materials, substances hazardous to health,
extremes of temperature.
1.5 Hazardous environment around the product
Consider: explosion risk areas, lack of oxygen (e.g. tanks, pits), dangerous gases,
extremes of temperature, hot surfaces, fire hazard (e.g. during welding), excessive
noise, moving machinery.

IM-IBR16-03 Issue 12 3
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.
1.8 Temperature
Allow time for temperature to normalise after isolation to avoid danger of burns.
1.9 Tools and consumables
Before starting work ensure that you have suitable tools and/or consumables
available. Use only genuine Spirax Sarco replacement parts.
1.10 Protective clothing
Consider whether you and/or others in the vicinity require any protective clothing
to protect against the hazards of, for example, chemicals, high/low temperature,
radiation, noise, falling objects, and dangers to eyes and face.
1.11 Permits to work
All work must be carried out or be supervised by a suitably competent person.
Installation and operating personnel should be trained in the correct use of the
product according to the Installation and Maintenance Instructions.
Where a formal 'permit to work' system is in force it must be complied with. Where
there is no such system, it is recommended that a responsible person should know
what work is going on and, where necessary, arrange to have an assistant whose
primary responsibility is safety.
Post 'warning notices' if necessary.
1.12 Handling
Manual handling of large and/or heavy products may present a risk of injury. Lifting,
pushing, pulling, carrying or supporting a load by bodily force can cause injury
particularly to the back. You are advised to assess the risks taking into account the
task, the individual, the load and the working environment and use the appropriate
handling method depending on the circumstances of the work being done.
1.13 Residual hazards

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 note:
- 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 105 mm (4.13").
Warning
The cover gasket contains a thin stainless steel support ring which may cause physical injur y
if not handled and disposed of carefully.
Please consult Spirax Sarco should further information be required.

IM-IBR16-03 Issue 128
4. Commissioning
After installation or maintenance ensure that the system is fully functioning. Carry out tests on
any alarms or protective devices.
5. Operation
T h e f l o a t t r a p i s a c o n t i n u o u s d i s c h a r g e t r a p , r e m o v i n g c o n d e n s a t e t h e i n s t a n t i t f o r m s .
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. When reassembling, ensure that all joint faces are clean.
6.2 How to fit the main valve assembly:
- Undo the cover bolts (2) and lift off the body (1).
- Remove the complete float assembly by undoing the two screws (7).
- Remove the main valve seat (5) and replace with a new one supplied with new gasket.
Note: A valve spring (item 28) is fitted to the DN25 (1") traps only.
- Fit a complete new float assembly by tightening the assembly set screws (7) to the
recommended torque (see Table 1).
-Refit the body (1) using a new gasket (3).
6.3 How to fit the air vent assembly:
- Remove the spring clip, element and spacer plate (17).
- Unscrew the seat.
- Fit a new gasket, seat and frame.
- Assemble the spacer plate, fit element and clips.
- Align the complete air vent horizontally so that the frame clears the cover.
