3. Installation
Note: Before actioning any installation observe the 'Safety information' in Section 1.
Referring to the Installation and Maintenance Instruction, 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.
Note: If the trap draining the manifold 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).
3.4 General information
The manifold has been designed for vertical installation. Ensure that there is sufficient
access to the handwheel to allow proper operation. The back is provided with threaded
connections M12 for attaching to a supporting structure.
For ease of insulation it is recommended that spacers are fitted to give the manifold a
stand-off of at least 50 mm.
For convenience the following sets of mounting kit are available:
-
A single set comprising 2 off each stud, nut and spacer suitable for installing one MSC04
or MSC08.
-
A single set comprising 4 off each stud, nut and spacer suitable for installing one MSC12.
-
A multiple set comprising 12 off each stud, nut and spacer suitable for installing 6 x MSC04,
6 x MSC08 or 3 x MSC12.
After installation it is recommended that the manifold is insulated to minimise radiated heat
losses and to protect personnel from burn risks. This is most easily done using the optional
insulating jacket.
3.5 Steam distribution duty
The recommended installation is with the steam inlet connection at the top of the manifold.
A trap set should be fitted to the bottom. The discharge from this trap set should ideally
be returned. If it is to be discharged to atmosphere we recommend that a diffuser is fitted.
3.6 Condensate collection duty
The recommended installation is with the condensate outlet at the top. The bottom of the
manifold should be fitted with a stop valve for blowdown purposes. Again, we recommend
that a diffuser is fitted.
3.7 Pipeline welding
Any welding provided by Spirax Sarco or our nominated sub-vendors will be in accordance
with our latest Weld Procedures and associated documentation. Copies are available, if
required, on request and should be approved before any orders are placed.
Any welding that is not being carried out by Spirax Sarco or their sub-vendors, will remain
the full responsibility of the customer, user or their own appointed contractors / sub-vendors.
