LOW PRESSURE FAULT

ISSUE

The refrigerant system’s low-pressure switch is showing as open.

RESOLUTION

Heat Only Units

Place heat pump in heating mode and perform the following troubleshooting.

1. Check for proper fan operation. If the fan is not operating, contact AquaCal

Technical Support.

2. Check for obstructed airflow around the heat pump.

See "

Clearances

" on page 45.

3. Check for a dirty or blocked evaporator coil.

See "

Cleaning Equipment

" on page 31.

4. Check for signs of heavy ice buildup on the coil.

Cool Only Units

Place heat pump in heating mode and perform the following troubleshooting.

Determine if an insufficient amount of water is being supplied to the equipment.

1. Confirm the filter pump is on.

2. If a multiple-speed filter pump is being used, run filter pump at a higher speed. Do not exceed the

maximum flow rate for the model.

3. Confirm water is not being diverted away from the heat pump.

Heat and Cool Units (Reversing)

Place heat pump in heating mode and perform the following troubleshooting.

1. Check for proper fan operation. If the fan is not operating, call for service.

2. Check for obstructed airflow around the heat pump.

See "

Clearances

" on page 45.

3. Check for a dirty or blocked evaporator coil.

See "

Cleaning Equipment

" on page 31.

4. Check for signs of heavy ice buildup on the coil.

LP5 SYSTEM LOCKOUT

ISSUE

The heat pump has locked due to five low-pressure faults during one call for heating or cooling.

RESOLUTION

1. Deactivate then reactivate power to the heat pump to clear error.

2. Troubleshoot the low-pressure issue causing the error.
