■ Remove front insulation shell.

■ The solar pump station forms a single unit with the wall 
    bracket and rear insulation shell. Secure both components 
   as a complete unit at the intended location, working the 
   front and using anchors and screws suitable for the wall 
    construction type.

■ The solar station is equipped with a solar safety relief valve 
    which meets the relevant requirements.

■  Fit the enclosed relief valve to the outlet of the return 
    instruments above the pump using the 3/4" union nuts. A  
  gasket is enclosed with the solar station for use when 
    installing the relief valve.

■ The enclosed discharge connection bracket should be fitted 
    to the safety valve so that there is no risk of scalding should 
   liquid escape. Follow local codes for drainage piping.

■ The safety valve must be easily accessible.

■   No valves should be placed between relief valve and pump 
   station. The relief valve should be piped to a suitable drain 
  as close as possible to the pump station with no reducing 
   couplings or other restrictions. The piping must be sloping 
   away from the pump station at all times.

■ Dirt traps or other constrictions are not permitted between 
   the collectors (field) and safety valve.

     the expansion tank, not forgetting the expansion coupling.
