has been diminished or a chemical feeder has become clogged or broken. First, check the chemi-
cal supply and chemical feeder. If both are in order check the Overfeed timer setting as it may need
to be increased to keep up with chemical demand.
ORP Tank Low
The ORP Tank Low alarm will sound when the chemical being fed falls below the chemical level
in the tank. First check the chemical level. If the level is above the sensor, check the sensor for
obstruction or calcification.
No Flow
The HCC 4000 is equipped with a flow sensor to prevent the controller from feeding chemicals in
the absence of proper recirculation. First check the filtration system to ensure that it is running and
that water is moving through the flowcell. If water is flowing and the alarm is still sounding check
flow sensor for obstruction.
When using the optional Digital Flow Sensor, the digital flow alarm setting can be entered in
gallons-per-minute to send a No Flow alarm when the filters require cleaning or backwashing.
Service Request
The Transmit button on the HCC 4000 sends logged data to the PoolComm web site for immediate
viewing and generates a service request alarm.
Key Inserted
When a service technician visits the HCC 4000 he may insert a service key (optional), which will be
logged by the controller to document the time and duration of his visit.
