Mounting
The reversing valve (QN10) is always installed between
the heat source and the hot water accumulator/rest of
the system. In the starting mode, without control
voltage, the reversing valve must be open to the rest of
the system. When control voltage is applied the revers-
ing valve opens to the hot water accumulator.
INSTALLING THE VALVE MOTOR
1.
Secure the valve motor (A) with a preinstalled spring
on the valve.
2.
Press the valve motor down until a click is heard.
The motor is then locked to the valve.
