Refill First; External Pilot Feed Adapter - Pentair AUTOTROL MAGNUM 293 Installer Manual

3.6.2

Refill first

The Logix 742-762 controllers allow you to refill the brine tank first when used in softener mode.
This feature allows the brine tank to be dry during the complete service cycle, reducing the caking
phenomena.
When a regeneration is initiated, the timer places the valve in refill position. Once the refill cycle is
done, the timer puts the valve back into service for 2 hours giving a sufficient time to make the
brine in the brine tank. After 2 hours the softener will operate a regeneration as usual, just
skipping the refill cycle that will be done just before the next regeneration cycle.
3.6.3

External pilot feed adapter

A small check valve is incorporated inside the Magnum pilot system. This removable and
replaceable check valve maintains the valve cartridge position in the event of pressure loss.
This check valve is compatible with an external pilot feed adapter and can be used with separate
source pilot pressure if desired.
1. Remove the pilot filter screen assembly (1).
2. Install the external pilot feed adapter (2) or the pilot system check valve (3).
