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.

Note: Before actioning any installation observe the 'Safety information' in Section 1.
Referring to the Installation and Maintenance Instructions, name-plate and Technical Information Sheet,
check that the product is suitable for the intended installation.
Warning: The cover gasket (item 3, Figure 2) contains a thin stainless steel support ring which may cause
physical injury if not handled and disposed of carefully.
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 Install a Y-type strainer immediately upstream of the trap to remove all pipeline debris.
3.4 Remove protection covers from all connections and protective film from all name-plates, where
appropriate, before installation on steam or other high temperature applications.
Installation notes:
-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.
-Traps are only available with horizontal connections allowing flow from right to left
(when looking at the name-plate), see Figure 1.
-Minimum withdrawal distance to remove the cover is 105 mm (4.13").
-Minimum withdrawal distance to remove the sensor is 130 mm (5.11").
Installation of the steam sensor (SS1)
3.5 The trap is supplied with a plug in the sensor connection on the cover.
3.6 Before fitting the sensor, isolate the trap from both the supply line and the return line, and allow any
pressure remaining in the pipeline to safely normalise to atmosphere.
3.7 Allow the trap to cool - Remove the plug from the trap and clean away any dirt before fitting the sensor.
Screw the sensor into the trap ensuring the gasket is centralised and tighten to the recommended
torque (see Table 1, page 8).
Installation of the waterlogging sensor (WLS1)
3.8 For fitting the waterlogging sensor refer to Sections 3.5, 3.6 and 3.7 above and the Installation and
Maintenance Instructions (IM-P087-34) which is provided with the sensor.
Please consult Spirax Sarco should further information be required.
3. Installation

IM-P615-12 CMGT Issue 4 9
IFTGS14 Ball Float Steam Trap ½" and ¾" with Integral Spiratec Sensor
After installation or maintenance ensure that the system is fully functioning. Carry out tests on any alarms
or protective devices.
The trap is supplied with a plug in the sensor connection on the cover. It is recommended that the trap be
operated under normal conditions for 24 hours before the plug is removed. This will allow pipeline debris to
be removed from the Y-type strainer prior to the sensor being installed.
Note: Failure to complete this commissioning process may affect the operation of the sensor.
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.
Note: Before actioning any maintenance programme observe the 'Safety information' in Section 1.
Warning
The cover gasket (item 3) 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 replace or clean the sensor:
-Important note: If a waterlogging sensor is fitted, it will be necessary to disconnect the wiring at the
terminal block.
-The sensor (24) should periodically be removed to inspect and clean the insulation as a build-up of
pipeline residue may affect the function of the sensor. Frequency of inspection will be dictated by
condensate quality.
-Remove the sensor (24) from the trap, clean the sensor insulation.
-If pitting of the insulation occurs, a new sensor should be fitted. Replace the sensor ensuring that the
gasket (25) is centralised. Tighten to the recommended torque (see Table 1).
-Reconnect the waterlogging sensor as described in IM-P087-34.
6.3 How to fit the main valve assembly:
-Undo the cover bolts (2) and lift off the body (1).
-Remove the complete float assembly (7, 8, 10 and 11) by undoing the two screws (7).
-Remove the main valve seat (5) and replace with a new one supplied with new gasket (6).
-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).
6.4 How to fit the air vent assembly:
-Remove the spring clip, element and spacer plate (17).
-Unscrew the seat.
-Fit a new gasket (18), seat and frame.
-Assemble the spacer plate, fit element and clips.
