2 About Lead Free Solder (PbF)
2.1. DISTINCTION OF PbF P.C. BOARD
P.C. Boards (manufactured) using lead free solder will have a PbF stamp on the P.C. Board.
2.2. CAUTION
· Pb free solder has a higher melting point than standard solder; Typically the melting point is 50 - 70 °F (30 - 40 °C) higher.
Please use a high temperature solder iron and set it to 700 ± 20 °F (370 ± 10 °C).
· Pb free solder will tend to splash when heated too high (about 1100 °F/ 600 °C).
If you must use Pb solder, please completely remove all of the Pb free solder on the pins or solder area before applying Pb
solder. If this is not practical, be sure to heat the Pb free solder until it melts, before applying Pb solder.

several minutes after the compressor has started up, F93 is stored in the memory as the symptom, and
operation stops.
2. Check the inverter circuit (for open circuits) in the control P.C. Board: Check the IPM base current (6
locations) within 3 minutes after the power has been turned back on. As the symptom, F93 is stored in the
memory 30 seconds after the compressor has started up, and operation stops. The trouble display
appears after 4 restarts.
3. Check for broken wires (open circuits) in the compressor winding: Approximately 1 ohm under normal
conditions for each phase (same symptom as in 2.)
4. Check the power supply voltage has been fluctuating or not.
F91Refrigeration cycle
abnormality
When the compressor frequency is above 55 Hz and the current drops below the prescribed level continuously
for 7 minutes, operation stops, and it is restarted 3 minutes later.
When the compressor discharge temperature has exceeded the setting and the expansion valve has remained
fully open for 80 seconds, operation stops, and it is restarted 3 minutes later.
When the stopping described above has occurred on 4 occasions, operation stops, and the trouble display
appears.
<Diagnosis checkpoint>
1. Check the refrigerating cycle: Gas may be leaking (more than one-half of the volume of the gas has gone).
The diagnostic displays resulting from a gas leak generally change in the following sequence depending
on the extent of the gas leak: H99 → F97 → F91 → H16.
The range of this trouble (F91) is limited. (Compressor protection at the start of the season)
F93Compressor
abnormal revolution
When a state in which the rotation of the compressor is not synchronized with the control signal has been
detected on 8 successive occasions, operation stops, and the trouble display appears.
<Diagnosis checkpoint>
1. To check whether the shutting valve has been left close by mistake, operation is performed for one to
several minutes after the compressor has started up, F93 is stored in the memory as the symptom, and
operation stops.
2. Check the inverter circuit (for open circuits) in the control P.C. Board: Check the IPM base current (6
locations) within 3 minutes after the power has been turned back on. As the symptom, F93 is stored in the
memory 30 seconds after the compressor has started up, and operation stops. The trouble display
appears after 4 restarts.
3. Check for broken wires (open circuits) in the compressor winding: Approximately 1 ohm under normal
conditions for each phase (same symptom as in 2.)
F95Outdoor high
pressure protection
CU-2E only
When the temperature of the outdoor unit heat exchanger temperature sensor exceeds 62 °C, the F95
diagnostic symbol is stored in the memory, and operation stops. 13 minutes later, operation is restarted at a
temperature below 48 °C. This trouble display appears when this happens on 4 occasions in a 20-minute
period.
<Diagnosis checkpoint>
1. Check the outdoor unit heat exchanger temperature sensor (check for changes in its characteristics and
check its resistance).
2. Check whether something is interfering with the dissipation of the heat outdoors.
When this trouble is detected from the electrical parts radiation fin temperature sensor and OLP output during
operation, operation stops, and it is restarted 3 minutes later. If the trouble occurs on 4 occasions, operation
stops, and the trouble display appears.
<Diagnosis checkpoint>
1. Something may be interfering with the dissipation of the heat outdoors or the outdoor unit fan may be
defective. (The outdoor unit fan is not running.)
2. Defective IPM (outdoor unit control P.C. Board)
3. Gas leaks. Shutting valve is not opened.
F97Compressor high
discharge
temperature
This trouble display appears and operation stops when this happens on 6 occasions (it is cleared when the
operation is normal for 20 minutes).
<Diagnosis checkpoint>
1. Check the refrigerating cycle: Gas may be leaking (the amount of refrigerant is low). The stopping of the
outdoor unit from time to time is a symptom of this trouble.
2. When operation steps with this trouble display appearing, check the compressor temperature sensor
(check for changes in its characteristics and check its resistance).
3. Something may be interfering with the dissipation of the heat outdoors or the outdoor unit fan may be
defective. (The fan will not run because of an open circuit.)
(The protection function may be activated by an overload, and the F97 trouble display will remain stored
in the memory.)
F98Total running current
protection
When the total current exceeds the setting (17A to 20A), frequency control is started, and if it then exceeds the
setting, operation stops, and the trouble display appears.
<Diagnosis checkpoint>
1. Check the AC voltage at the outdoor unit terminal board during operation: The voltage drop must be within
5% of the voltage when operation has stopped (± 110% of rated voltage even during operation). If the
voltage drop exceeds 5% or if the voltage changes suddenly, inspect whether the power supply cord and
indoor/outdoor unit connection cables are too long or too small in diameter, etc.
2. Check whether something is interfering with the dissipation of the heat outdoors (during cooling
operations): Normally, the capacity is limited by the current so that the outdoor unit don’t stop, and the
diagnostic display does not appear.
F99DC peak detectionWhen “Output current trouble”, which occurs when the prescribed current level is exceeded, has occurred on
16 consecutive occasions, operation stops, and the trouble display appears.
<Diagnosis checkpoint>
1. Check whether the compressor is defective (locked up or shorted winding). Check the outdoor unit control
