INTRODUCTION 1.3 Indoor Unit The indoor unit can ﬁt easily 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 that stops compressor operation in case drainage tube is blocked. • A bended coil with treated aluminium ﬁns. • 3-speed fan motor with internal protection with extra speed for higher external static pressure.
PAGE 6
INTRODUCTION 1.7 Outdoor Unit The DNG outdoor units can be installed as ﬂoor or wall mounted units by using a wallsupporting bracket. The metal sheets are protected by anti- corrosion paint work allowing long life resistance. All outdoor units are pre-charged. For further information, please refer to the Product Data Sheet, Chapter 2.

CONTROL SYSTEM 13.10 System Diagnostics Pressing Mode button for 5-10 seconds in SB or any other operation mode will activate the DIAGNOSTICS mode, acknowledged by 3 short beeps and lighting of COOL and HEAT LEDs. In DIAGNOSTICS mode, system failures will be indicated by the blinking of HEAT & COOL LEDs. The coding method is as follows: HEAT LED blinks 5 times in 5 seconds, and then turns off for the next 5 seconds. COOL LED blinks during the same 5 seconds according to the following table: No.

TROUBLESHOOTING 14. TROUBLESHOOTING ELECTRICAL & CONTROL TROUBLESHOOTING ATTENTION: check for broken or loose cable lugs ﬁrst. NO SYMPTON PROBABLE CAUSE CORRECTIVE ACTION 1. The stand-by indicator (red led) on the central control display panel doesn’t light up. There is no correct voltage between the line and neutral terminals on main P.C.B. -If the voltage is low repair power supply. -If there is no voltage repair general wiring. -If there is correct voltage replace main or display P.C.B’S 2.
