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 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 protective film from all name-plates, where
appropriate, before installation on steam or other high temperature applications.
3.4
The preferred installation is in a horizontal pipe with the insulating cover uppermost (see Figure 3).
The trap will operate in any position, but the service life may be affected.
Note: When a socket weld trap is being installed the welding should be carried out to an approved
procedure of a recognised standard.
3.5
Observe the flow direction markings on the trap body. Stop valves should be installed so as to
permit the isolation of the trap from both supply and return line pressure. If the trap discharges to
atmosphere, the discharge should be directed to a safe place.
Note:
the disc and seating surfaces of these traps have been produced to a high degree of flatness
to achieve good shut-off under high pressure conditions. An integral strainer helps prevent dirt and
scale from entering the trap. If particles become entrapped between the disc and seat, the high
flow velocities can cause rapid wear and erosion. A separate strainer and/or dirt pocket will provide
additional protection.
3.6
Access for removal of the integral strainer screen should be provided.
3.7
The insulating cover may be removed to facilitate installation, but it must be replaced before the
trap is put into service.
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).
