2.4 Inspection and Performance Confirmation

2.4.1 Receiving Inspection

Although Spirax-Sarco Limited carries out a full inspection of all units before dispatch, damage 

may occur during transit. On receipt of the unit, a visual inspection will show any external 

damage and hence indicate any possible internal damage that may have occurred. If damage 

has occurred, please do not hesitate to contact us.

2.4.2 User’s Rating Inspection

Before installation of the SJT Steam Jet Thermocompressor, the user must ensure that the 

mechanical rating of the unit is suitable for the intended service.

Details of the mechanical rating can be found on the name-plate and associated documentation.
