30RA/30RH Electrical connections and refrigerant charge Electrical connections Liquid refrigerant charge WARNING: To prevent electrical shock or equipment damage, make sure disconnects are open before electrical connections are made. If this action is not taken, personal injury may occur. Checking the charge Power supply cable size and external connection must be made by the installer according to the unit installation characteristics and the applicable standards.
30RA/30RH Refrigerant charge and electronic control Undercharge If there is not enough refrigerant in the system, this is indicated by gas bubbles in the moisture sight glass. There are two possibilities: • Small undercharge (bubbles in the sight glass, no significant change in suction pressure). - After detection and repair the unit can be recharged.
30RA/30RH Start-up, compressor and pump replacement, unit protection devices ENGLISH Start-up Unit start-up is done by the electronic control described above, and must always be carried out under the supervision of a qualified air conditioning engineer. Necessary checks/precautions before start-up - Ensure that all electrical connections are properly tightened. - Ensure that the unit is level and well-supported.

In case of use other than the manufacturer configuration, Carrier Service must be asked for permission to change the Pro-Dialog Plus system configuration.
30RA/30RH General maintenance, maintenance and final recommendations E N G L I S H General maintenance ATTENTION: Before starting any servicing or maintenance operation on the unit, make sure that the power supply has been disconnected. A current discharge could cause personal injury. In order to obtain maximum performance from the unit special attention should be paid to the following points. - Electrical connections: The supply voltage should be within the limits indicated in Table II.
30RA/30RH Troubleshooting A list of possible faults, as well as the probable cause and suggested solutions is shown as follows. In the event of a unit malfunction it is recommended to disconnect the power supply and ascertain the cause. Symptoms Cause REMEDY Unit does not start: - No power supply; CONNECT POWER SUPPLY. - Main switch open; CLOSE SWITCH. - Low line voltage; CHECK VOLTAGE AND REMEDY THE DEFICIENCY. - A protection has tripped; RESET.
