1. Precautions
1. Warning: Prior to repair, disconnect the
power cord from the circuit breaker.
2. Use proper parts: Use only exact
replacement parts. (Also, we recommend
replacing parts rather than repairing them.)
3. Use the proper tools: Use the proper tools
and test equipment, and know how to use
equipment may cause problems laterintermittent contact, for example.
Fig. 1-1 Avoid Dangerous Contact
4. Power Cord: Prior to repair, check the
power cord and replace it if necessary.
5. Avoid using an extension cord, and avoid
tapping into a power cord. This practice
may result in malfunction or fire.
6. After completing repairs and reassembly,
check the insulation resistance, Procedure:
Prior to applying power, measure the
resistance between the power cord and the
ground terminal. The resistance must be
greater than 30 megohms.

3-2-8 About the safety devices
1. High temperature release : If temperature of the indoor pipe thermistor increases over the specified value during heating
operation, following operation is carried out for safety of the equipment.
A condition : temperature of indoor pipe thermistor is below 47˚C
B condition : temperature of indoor pipe thermistor is between 58˚C and 63˚C
C condition : temperature of indoor pipe thermistor is over 63˚C
1) High temperature release operation OFF condition = A condition
-> compressor ON (only in THERMO ON condition)
-> fan motor speed = set fan speed and cool blowing inhibiting operation
2) High temperature release operation ON condition = B condition
-> compressor ON
-> fan motor speed = HIGH operation if it was LOW
= HIGH operation if it was HIGH
3) High temperature release operation ON condition = C condition
-> fan motor speed = set fan speed
-> compressor OFF
2. Low temperature release : If temperature of the indoor pipe thermistor decreases below the specified value during cooling
operation, following operation is carried out for safety of the equipment.
A condition : temperature of indoor pipe thermistor is below -1˚C for more than 6 minutes
B condition : temperature of indoor pipe thermistor is over 5˚C
1) Low temperature release ON condition = A condition
-> compressor OFF
-> fan motor "set fan speed"
2) Low temperature release OFF condition = B condition
-> The compressor is turned on if ON condition is satisfied after comparing the ambient temperature with the set
temperature
-> fan motor "set fan speed"
[Detailed description]
1) If temperature of indoor pipe thermistor is below -1˚C for more than 6 minutes, the fan motor continues to operate at
the set fan speed and the compressor is turned off(Low temperature release operation)
2) If temperature of the indoor pipe thermistor increases over +5˚C during low temperature release operation, normal
operation is recovered
: compressor ON, fan mtor set fan speed -> Low temperature release operation OFF
3) If temperature of indoor pipe thermistor increases over 0˚C during counting 6 minutes below -1˚C, the counter is reset.
