3. Installation
Note: Before actioning any installation observe the 'Safety information' in Section 1.
All traps must be installed in horizontal pipework, preferably preceded by a small dropleg.
Suitable isolation valves must be installed to allow for safe maintenance or trap replacement.
Where the trap discharges into a closed return system a non-return valve should be fitted
downstream to prevent return flow, (on the ITD32 the non-return valve should be positioned
1 metre downstream of the trap outlet). Remove all packaging and protective covers and
ensure all connection ports are clear from obstruction. Always open isolation valves slowly
until normal operating conditions are achieved - this will avoid system shocks. Check for leaks
and correct operation. Always ensure the correct tools, safety procedures and protective
equipment are used at all times. When welding IBP21, IBP21S, IBP30 and ISM21 traps into
the pipeline, there is no need to remove the element/capsule providing the welding is done
by the electric arc method.
Note:
The trap is supplied with a plug in the sensor adapter. It is recommended that the trap
be operated under normal conditions for 24 hours before the plug is removed. This will allow
any pipeline debris to be removed from the strainer prior to the sensor being installed. Failure
to complete this commissioning process may affect the operation of the sensor. Before fitting
the sensor, the trap must be isolated from both supply line and return line, and any pressure
allowed to safely normalise to atmosphere. The trap should then be allowed to cool. Remove
the plug from the adapter ensuring the trap is securely held and replace with the sensor. Screw
into the adapter ensuring the gasket is centralised. Tighten to the recommended tightening
torque. If a waterlogging sensor is to be fitted it will be necessary to carry out the installation
procedure in IM-P087-34 which accompanies the sensor.
