IMPORTANT GENERAL INFORMATION  

 
With a constant concern of improving our products, we reserve the right to make 
changes to this manual without prior notification.  
 
All statistics and explanations within this manual were believed to be correct at the 
time of printing.  
 
Each RETRACT installation requires a preliminary study of performance and 
feasibility.  
This study covers 3 distinct sub systems :  
 
1.  The RETRACT thruster unit, (positioning ,space available ,structural compatibility  

etc) 

2.  Hydraulic equipment, (positioning equipment ,power available , flows pressures 

pipe sizes etc) 

3.  Electrical equipment, (positioning ,power supply , protection / isolation ,etc ) 
 
 

CHECK LIST FOR THE PROJECT MANAGER  

 
It is very important to carefully read the entire manual before starting the installation. 
 
At the end of the manual, you will find a MAJOR POINT CHECKLIST when you are 
inspecting the work of your installers. All the points listed must be strictly respected 
for the proper and safe operation of the RETRACT system.
