HP5 SYSTEM LOCKOUT

ISSUE

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

RESOLUTION

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

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

See "

HIGH PRESSURE FAULT

" on the previous page.

LOW PRESSURE FAULT

ISSUE

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

RESOLUTION

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, contact Leisure Temp Technical Support.

2. Check for obstructed airflow around the heat pump.

See "

Clearances

" on page 20.

3. Check for a dirty or blocked evaporator coil.

See "

Cleaning Equipment

" on page 19.

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 .

RESOLUTION

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

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

See "

LOW PRESSURE FAULT

" above.

MULTI-UNIT COMM FAULT

ISSUE

Slaved heat pump is not receiving a signal from the master heat pump.

RESOLUTION

1. Confirm the master heat pump is operating correctly. If, for example, no power is supplied to the master

heat pump, an error will appear on the slaved heat pumps.

OTA SYSTEM LOCKOUT

ISSUE

A malfunction has occurred that could allow the water temperature to surpass a safe level. An installed
"Over Temperature Alarm" kit has disabled the system.

See "

Available Accessories

" on page 40 for more information.

RESOLUTION

Call for service.
