3.1 Fault Codes

A fault code indicates a specific issue or condition that will require action before the equipment can resume
operating.

Please perform the following troubleshooting.

If the issue reoccurs, please

see "Contacting AquaCal AutoPilot, Inc." on page 1.

WARNING

Failure to heed the following may result in injury or death.

l

Repairs must not be attempted by untrained or unqualified individuals.

l

The chiller contains refrigerant under high pressure. Repairs to the refrigerant circuit must not be attempted by
untrained or unqualified individuals. Service must be performed only by qualified HVAC technicians. Recover
refrigerant before opening the system.

NOTICE

Failure to heed the following may result in damage to equipment.

l

Service by unauthorized personnel will void the chiller warranty.

FLO

Indicator

ISSUE

Low or no water detected.

RESOLUTION

1. Confirm the filter pump is on.

2. If a multiple-speed filter pump is being used, run at a higher speed to determine if the error persists. Do not

exceed maximum flow rate for your model.

3. Confirm water is not being diverted away from the chiller.

l

See "Water Flow Rates" on page 9.

FS

Indicator

ISSUE

The chiller has sensed the evaporator coil is icing up.

RESOLUTION

Cool Only Units

When ice starts to form on the coil, the compressor will stop operating while the fan continues to operate.

l

When the coil's temperature rises above 38° F, the compressor is restarted and cooling resumes.

l

If the coil's temperature remains below 38° F, the compressor will remain off.

CEr

Indicator

ISSUE

This can indicate a loose or damaged communication cable.

RESOLUTION

A qualified technician should check the cable from control board to display assembly for a loose connection or
visible damage.
