For any alternative control or pipework position, contact us on the 
number opposite.

2.0 HANDLING

Upon receipt of the equipment an inspection should be made, and 
before commencement of lifting ensure that normal equipment safety 
checks have been carried out.

The unit/sections should be removed from the vehicle using a fork lift 
or crane. Always handle with care to avoid damage and distortion, and 
where lifting slings are employed use spreaders to ensure slings do not 
come into contact with the unit case, or control pack (Figure 4).

Correctly position slings to avoid twisting of the unit case and observe 
the centre of gravity before the final lift is made.

Note: The weight of the unit from the rating plate.

Dependent on model and size units may be supplied in single or  
multi-module sections. Handle each section individually 

do not stack 

for lifting or storage.
