3. Installation 

Lifting & Handling: 

 

Use lifting lugs where fitted.  

 

Do not lift a vessel using the insulation where fitted.  

 

Straps may crush or damage the insulation casing.  

 

Due to the insulation casing material thickness, care should be taken when moving and handling the 
vessel not to damage the insulation.  

 

Do not lift the vessel using chains directly in contact with the shell.  

 

Do not allow operatives to stand on the vessel. 

IMPORTANT NOTE:

 When lifting, please ensure clean lift of the vessel using the top lifting lugs, then using the 

Tailing lug; swing the bottom out avoiding pivoting on the legs or ring stand.  

When standing the vessel back up, reverse this procedure. 

NB: The legs / ring stand are not designed for pivoting during this operation. 

Siting: 

 

Unless specifically ordered for an external installation, the vessel must be sited indoors. 

 

Foundations or plinths must be firm and level to prevent settling, pipe strain or distortion of the shell. 

 

Unless specifically ordered differently, the vessel must be installed in a level position. 

 

Protective covers and plugs may be fitted to connections to protect them in transit,  these must be 
removed prior to use. 

 

If a connection is not required, seal it appropriately.  

 

Check for any foreign material which may have got into the vessel. 

 

Pipe-work connected to the vessel must be adequately supported to prevent any loads being transmitted 
to the vessel. Provide for thermal expansion with bends and expansion joints. 

 

Fit isolation valves prior to the vessel connections to facilitate servicing 

(NOT TO THE VENT)

 

For flanged connections, tighten bolts in a diametrically opposite sequence to load the flanges evenly 
onto the gasket. 

 

Ensure adequate venting for air removal during filling and operation (pressurised systems should have an 
automatic air vent and a manual air vent for this). 

 

Safety valves should have their discharge pipes away to a safe disposal point, preferably via an air- break 
and tundish so that the discharge unrestricted and easily visible. 

 

Water expansion must be accommodated by a separate expansion vessel fitted in the system. 

Important Notes: 

Insulated vessels – When filling/in operation, take extra care to avoid any spillages or leaks from the connections - 
particularly top connections. 

Any water between the insulated jacket and the shell will void any warranties as severe corrosion is likely. 

HRS will not take responsibility for any corrosion due to water ingress between shell and jacket. 

The unit should be flushed thoroughly with clean water prior to operation.

 

4. Commissioning & Operation

 

Do not operate the equipment at pressures or temperatures in excess of those specified on the nameplate or the
