INTRODUCTION 1. INTRODUCTION 1.1 General The GCD 030 R410A can be matched to the following models: ● PNX 30 DCI ● SX 30 DCI ● CKD 30 DCI ● DLS 30 DCI Remote control compatibility The PNX, SX, CKD, DLS units are compatible with remote controls RC3, RC4, RCW1, RCW2. 1.2 Main Features The GCD 030 benefits from the most advanced technological innovations, namely: ● Sine wave form in both OFAN and Compressor drives. ● Partial switching PFC control.
INTRODUCTION 1.3 Indoor Units The DLS 30 indoor unit is a low silhouette ducted unit, and can be easily fitted to many types of residential and commercials applications. It includes: • High technology plastic fan and fan housing. • A drain pool that is under the entire unit with internal downward slope. • An over-flow switch, stops compressor operation in case of is blocked drainage. • A bended coil with treated aluminium fins.
INTRODUCTION 1.4 Feature PNX 30 Display Ionizer ESF Fresh air Indoor fan motor Horizontal motorized louver Vertical motorized louver Heating element M2L Cable port Dry contact LCD Yes Yes No Variable Speed (PG) Yes Yes No Yes Presence detector or (Jumper selected) power shedding Filtration • The unit is equipped with pre filters. • Easy and versatile access, rear or bottom, can be easily adjusted by the installer. 1.
INTRODUCTION 1.9 Accessories RCW Wall Mounted Remote Control The RCW remote control is mounted on the wall, and controls the unit either as an infrared remote control or as a wired controller. The wired controller can control up to 10 Indoor units with the same program settings and adjustments. For further details, please refer to the Technical Service Manual. 1.10 Inbox Documentation Each unit is supplied with its own operation/installation manual. 1.11 Matching Table 1.11.

TROUBLESHOOTING 13 TROUBLESHOOTING FOR GC030 WARNING!!! When Power Up – the whole outdoor unit controller, including the wiring, is under HIGH VOLTAGE!!! Never open the Outdoor unit before turning off the Power!!! When turned off, the system is still charged (400V)!!! It takes about 1 Min. to discharge the system. Touching the controller before discharging may cause an electrical shock!!! For safe handling of the controller please refer to section 14.1.5 below 13.

TROUBLESHOOTING 13.1.3.3 Fault Code for Indoor unit Pressing Mode button for long will activate diagnostic mode by the acknowledgment of 3 short beeps and lighting of COOL and HEAT LED’s. Entering diagnostics in STBY mode allows only viewing of status (fault-display). In diagnostic mode, system problems / information will be indicated by blinking of Heat & Cool LED’s. The coding method will be as follows: Heat led will blink 5 times in 5 seconds, and then will be shut off for the next 5 seconds.
TROUBLESHOOTING 13.1.3.4 No.
TROUBLESHOOTING 13.1.4.4 Checking the Outdoor Fan Motor Check FAN-Power and FAN-Halls connections - Repair if needed. Rotate the fan slowly by hand. If the fan does not rotate easily, check whether something is obstructing the fan, or if the fan itself is coming into contact with the outer case, preventing it from rotating. Correct if necessary - otherwise, the fan motor bearings have seized. Replace the motor.
TROUBLESHOOTING 13.1.4.10 Checking for electromagnetic interferance (EMC problems) 13.1.4.10.1 EMC troubles to the A/C unit Locations most susceptible to noise : 1. Locations near broadcast stations where there are strong electromagnetic waves. 2. Locations near amateur radio (short wave) stations. 3. Locations near electronic sewing machines and arc-welding machines. Trouble : Either of the following trouble may occur: 1. The unit may stop suddenly during operation. 2.
TROUBLESHOOTING 13.1.6. Advise: Open the Outdoor unit controller cover only after one minute from power off. Measure the electrolytic capacitors voltage before farther checking controller. Additional advises When disassemble the controller or the front panel, turn off the power supply. When connecting or disconnecting the connectors on the PCB, hold the whole housing, don’t pull the wire, there are sharp fringes and sting on shell. Use gloves when disassemble the A/C units.
