Maintenance - Herrmidifier Herrtronic AD Owner's Manual

Maintenance

To maintain efficiency, the water level in the cylinder will
slowly move upwards, as the electrodes become coated
with minerals, to expose new electrode to the water.
Eventually all of the usable electrode surfaces will be
coated and the cylinder will be full of water. At this point,
the "cylinder full" light will turn on and the output will
begin to fall. This indicates the need to change the
cylinder – typically 500-2000 hours of operation,
depending on water supply.
To remove the cylinder
1. Drain cylinder completely using the Manual Drain
Switch.
2. Turn off power to the unit. Disconnect electrode
power wires and cylinder full electrode wire from
tank.

3. Remove tank and replace with new one. Be sure
that both "o" rings are in place on the cylinder
fill/drain neck prior to installation. Clean and check
both the fill and drain solenoids while servicing the
unit. Check strainer. If it is dirty or restricting water
flow – replace. Insert new fill valve / strainer.
4. Install cylinder in unit. Make sure that all electrical
connections are securely tightened.
5. Follow cold start-up instructions on page 11.
Extended Shutdown
Always drain cylinder completely if unit will be off for an
extended period of time. This will preserve the life of the
cylinder.
