Sediment Drain Ball Valve - Pontos AquaCycle 2500 Instrucciones De Montaje

7.3. Sediment drain ball valve

The electric 2-way PVC ball valves DN50 drain
off the sediments from the tanks B2 and B3
and back-flushed solids from the filter F1 at
regular intervals.
Checking the ball valve
Check the ball valve when the controller is in
"manual operation". When doing this, pay
attention to the rotation of the hand wheel and
the flow noises.
If there is a power failure, the desired position
can be set with the manual emergency
actuator.
The manual emergency
actuator is an emergency
actuator. It may only be
turned clockwise (see
arrow on the handle).
Replacing the ball valve
All functionally important
parts inside the device are
lead-sealed. The warranty
is void if the lead seals are
damaged.
Before removing the ball valve,
drain all water out of the relevant
tank.
1. Allow the filter / relevant tank to drain
completely empty via the ball valves.
2. Unplug the system's main plug.
