F ea tur es Fea eatur tures Higher Energy Savings The compressor in McQuay DC Multi Split Inverter is programmed to run at the optimum speed. The compressor speed is controlled by input frequency that varies according to the indoor load requirements. Once the indoor set temperature is achieved, the input frequency supply to the compressor will be reduced. Hence, less energy is required to maintain the unit operation and this will consume less energy.

Troub leshooting oubleshooting When a malfunction of the air conditioner unit is detected, immediately switch off the main power supply before proceeding with the following troubleshooting procedures. The following are common fault conditions and simple troubleshooting tips. If any other fault conditions which are not listed occur, contact your nearest local dealer. DO NOT attempt to troubleshoot the unit by yourself. No 1 2 3 Fault conditions The air conditioner unit will not resume after power failure.
Diagnostic Guideline By means of pressure readings • • High side Low side High side Low side High side Low side High side Low side High side Low side • • • • • • Probable cause Too high A little high Normal A little low Circuit Pressure Too low Data • • 1. 2. 3. 4. Overcharged with refrigerant. Non-condensable gases in refrigerant circuit (e.g. air) Obstructed air-intake / discharge. Hot air short circuiting in outdoor unit. 1.
By Means Of Diagnostic Flow Chart: Generally, there are two kinds of problems, i.e. starting failure and insufficient cooling/heating. “Starting failure” is caused by electrical defect while improper application or defects in refrigerant circuit causes “Insufficient cooling / heating”.
1 2 Condenser fan contactor Faulty Coil burnt Contact faulty Fan motor faulty Other electrical component faulty Compressor contactor Change the contactor Faulty Change the contacts Repair or change the motor contactor Repair or change if necessary Coil burnt Contact faulty Open compressor windings Incorrect wiring The most common causes of air conditioner failure to “start” are : a) Voltage not within ±10% of rated voltage. b) Power supply interrupted. c) Improper control settings.
ii ) Diagnosis of Refrigerant Circuit / Application There might be some causes where the unit starts running but does not perform satisfactorily, i.e. insufficient cooling. Judgement could be made by measuring temperature difference of indoor unit’s intake and discharge air as well as running current.
Insufficient heating Air circulation Restricted Indoor / outdoor coil dirty (clogged) Indoor air filter dirty Fan motor malfunction Obstruction at air inlet / outlet of indoor / outdoor unit High heating load Refrigerant circuit Windows / doors wide open Refrigerant short charge or refrigerant leakage Restriction e.g. at strainer, capillary, filter dryer, etc.
