7.1- PRECAUTIONS BEFORE PERFORMING INSPECTION OR REPAIR 

-

 

Be  cautious  during  installation  and  maintenance.  Follow  the  codes  and  regulations  to  avoid  electric  shock  and  casualty  or  even  death.  Static 
maintenance is the maintenance during de-energization of the heat pump. 

-

 

For static maintenance, make sure that the unit is de-energized. 

-

 

Dynamic maintenance is the maintenance during energization of the unit. 

-

 

Before dynamic maintenance, check the electricity and ensure that there is ground wire on the site. 

-

 

Take sufficient care to avoid directly touching any of the circuit parts without first turning OFF the power. 

NOTE:

 A large capacity electrolytic capacitor is used in the outdoor unit controller (inverter). Therefore, if the power supply is turned OFF, charge (charging 

voltage DC280V to 380V) remains and discharging takes a lot of time. After turning off the power, if touching the charging section before discharging, an 
electrical shock may be caused. Discharge the electrolytic capacitor completely. 

Remove the inverter cover 

 

7.2- VERIFICATION 

(1)  Verify the power supply 

Confirm that the circuit breaker is in the ON position 

(2)  Confirmation of power voltage 

Confirm that power voltage is AC 208-230 ± 10 %. If power voltage is not in this range, the unit may not operate normally.
