Installation Procedures 

Hydrastep Pressure Parts 

The procedures apply to the Hydrastep Boiler Drum Water Level Equipment supplied by 
Mobrey, who are responsible, under their supply contract, for delivery of all items of the 
above equipment listed in the delivery schedules. 

Mobrey are not responsible for handling, storage, installation and protection of equipment on-
site.  However, the procedures define the requirements for these activities which must be 
complied with to allow Mobrey to meet their contractual obligations for the efficient 
performance of equipment supplied by them. 

The items of equipment are listed in detail on the ‘Packing Note’ that is issued with the 
equipment to the site. 

The storage area must be dry, dust-free and under cover. Storage conditions should be 
controlled within the temperature range of 10

C to 40C (50F to 104F) with a maximum of 

80% R.H. 

The equipment shall be stored, where possible, in the original or robust packages to prevent 
accidental mechanical damage.  The equipment shall be stored on shelving or racks above 
ground level as further protection from mechanical damage and to eliminate dampness. 

If the equipment is to be stored for a long period, suitable access is to be provided so that 
regular inspection can take place.  These inspections should check for signs of physical 
deterioration, and should take place at least every three months. 

The water columns are heavy and lifting equipment suitable for hoisting up to 50kg should be 
used, both for inspection and carriage.  The electrodes should be handled with considerable 
care, both for inspection and installation.  The electronic units should be protected from 
electrostatic damage, induced via signal input terminals. 

The Water Column is delivered with all electrode ports fitted with plastic inserts.  These 
inserts should not be removed until the electrodes are due to be installed.
