5. REVERSAL OF THE SUPPLY AND RETURN LINE
To reverse the supply and return line:
1. Remove the pumping group from the insulating jacket (12).
2. Unscrew the return line sleeve (9) from the ball valve (6).
3. Unscrew the cap nut (10) of the ball valve (5) and disconnect the pump (8) together with
the ball valve (7).
4. Remove the non-return valve (13) out of the ball valve (6) and install it into the ball
valve (5).
5. Fasten the pump (8) to the ball valve (6), and the return line sleeve (9) to the ball valve (5).
6. Remove handles (1) and (2) with thermometers (3) and (4) from the ball valves (5) and
(6) and interchange them.
7. Rotate the insulating jacket body (12) to 180° and insert the resulting pumping group
into it.
8. If the bypass valve is installed instead of the blind connection (1 1), it should be removed,
rotated to 180° and installed back. The arrow on the casing of the bypass valve should be
directed from the supply line to the return line.
