Connect the cable from ROPRE to the mains.
Check that the pump rotates in the direction indicated on the
pump. If the direction is incorrect, switch two of the phases in
the connection to the pump in TRECI (3-phase versions only).
Replace the outlet tube on the pump in TRECI with the non-

Struers recommends that you seal the threads.
Connect the pressure hose of RotoPol-31/-35 to the hexagon
nipple. Remember to mount the gasket.
Select the reduction piece from ROPRE which fits the drain
hose of RotoPol-31/-35. Mount the piece on the outlet angle of
the TRECI.
Shorten the drain hose if necessary. Fix the drain hose on the
reduction piece: strip away a short length of the steel
reinforcement in the drain hose and mount a hose clamp on
the stripped end.
Mount the outlet angle on TRECI.
Avoid sharp bends in the drain hose and make sure that the hose slopes
