General Service Hints For Meter Control
Problem: Softener delivers hard water
Reason: Reserve capacity has been exceeded.
. Correction: Check salt dosage requirements and reset reserve capacity to provide additional reserve.
Reason: Meter is not measuring flow.
. Correction on Mechanical Meter: Check with meter checker kit. If volume is not registering, check the .
meter cap and impeller for debris, and ensure they can move freely.
. Correction for Electronic Meter: Check for a short in the meter cable. Ensure that it is programmed as .
a meter, and that the turbine and impeller can move freely.
