BPT13 Balanced Pressure Thermostatic Steam Traps
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:
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 tted, ensure that a safety device
is included in the system to prevent overpressurisation.
3.2
Determine the correct installation situation and the direction of uid ow.
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.
3.4
The BPT13 is designed for installation with the capsule in a horizontal plane with the cap at the top.
Ideally, as with all thermostatic steam traps, a drop / cooling leg should be employed to prevent any
'cooling' condensate from backing up into the steam main.
3.5
When the trap is discharging to atmosphere, it is strongly recommended to install a diuser on the
outlet side of the trap.
This reduces any problem of noise end erosion by cushioning high velocity discharge.
See TI-P155-02 for further information.
3.6
Isolation valves must be installed to allow for safe maintenance and trap replacement.
3.7
Open the isolation slowly until normal operating conditions are achieved.
3.8
Check for leaks and correct operation.
3.9
Ensure adequate space is left to remove the cover from the body for maintenance. Minimum withdrawal
distance for the cover is 55 mm.
Note: If the trap is to discharge to atmosphere ensure it is to a safe place as the discharging uid may be
ast a temperature of 100 °C (212 °F).
