Clamp ring screw connections
■ Cut the copper pipe to length and deburr.

   clamp ring. 
■ Insert the prepared pipe into the screw connection until its 
   stop is reached. 
■ Tighten clamp ring nut by hand.
■  Use open-ended wrench to tighten clamp ring screw 
     connection (approx. 33 Ft lb),  re-tighten if necessary.
■ When tightening the clamp ring screw connection, use two 
    wrenchesusing one wrench to prevent the pumping station 
    from turning.
Flat seal screw connections
■  All pre-fitted solar station screw connections are firmly 
   tightened in the factory so that they do not need to be 
     retightened. 
Torque levels when tightening flat seal screw connections 
using AFM 34 flat seals, s = 2mm.
 
– 3/4" screw connection 26 Ft. lb
 
 1" screw connection 40 Ft. lb
 
 1 1/4" screw connection 66 Ft. lb

Operation, multi-function ball valve and 
check valve
■ The forward flow ball valve must be open for filling, flushing 
   and bleeding solar systems with a filling and flushing pump. 
   The return ball valve should be closed.
■  Both flow checks should be opened in order to drain the 
    solar system (thermometer handles in 45° position).
■  The two mult-function ball valves must be fully open in 
  order to operate the solar system (turn the red and blue 
  thermometer handles counter-clockwise until the stop is 
    reached).
