2. FEATURES Invisible Operation The unit is installed concealed above the ceiling. ACC-D is designed to intelligently create a comfortable and healthy indoor air climate, while remaining invisible. This allows user to enjoy conditioned air without sacrificing room space or interior design creativity. Flexibility in System Design The unit offers fan motor that can operate up to 4 speeds, thus provide choices of external static pressure for designing ducting system. Easy Serviceability With the concept of easy serviceability in mind, ACC-D series is designed for easy access to internal components. The internal components, such as fan motor or blower, can be easily accessed for servicing through both sides or bottom of the unit. High Level of Protection The unit is incorporated with a unique safety feature, i.e. a float switch, to provide an additional protection from possible problems of condensate water over flow inside the unit. Once the condensate water reaches critical level, the level switch will be activated and signal will be sent to the microprocessor controller to stop the compressor as well as sending an error message to the wired controller, alerting the user, for further action. Wired Remote Controller The standard unit comes with the Netware III controller, which offers wide range of control features that, includes 7 days and 24 hours timer setting and more. The ACC-D series is able to communicate with the versatile NIM network control module and offers the opportunity of one centralized control for a system of multiple indoor units in a building. Auto Random Restart Auto random restart function allows the unit to automatic restart as the last setting condition when the power supply is resumed after power failure. However, the compressor will restart randomly if more than one unit is installed and sharing the same phase of power. Self Diagnosis The microprocessor provides the possibility to detect and diagnose any fault or malfunction that occurs in the system. The error will be reflected by the wired remote controller with a series of error code. 4

5. 7. PERFORMANCE TABLE Interpolation and Extrapolation method can be used to get the total capacity, TC and sensible capacity, SC at those temperatures which are not stated out in the table. Example: Model: ACC 75D AMC 75D Indoor Condition: 23 C DB, 15 C WB Outdoor Condition: 37 C DB Solution: Overall Based on the Performance table on Pg. 29, 1. Refer to the Indoor DB column, - 23 C is located between 20 C and 24 C (Thus, Interpolation need to be applied) 2. Refer to the Indoor WB column, - 15 C only available in the case of Indoor DB = 20 C. (Thus, Extrapolation between 16 C WB and 17 C WB during 24 C indoor DB is required) 3. Refer to the Outdoor DB column, - 37 C is located between 35 C and 40 C. (Thus, Interpolation need to be applied) Please follow the steps below in order to get the required capacity. 1 st Step Extrapolation of Indoor WB Find TC, SC for (a) Indoor: 24 C DB, 15 C WB Outdoor: 35 C DB (b) Indoor: 24 C DB, 15 C WB Outdoor: 40 C DB 2 nd Step Interpolation of Indoor DB Find TC, SC for (a) Indoor: 23 C DB, 15 C WB Outdoor: 35 C DB (b) Indoor: 23 C DB, 15 C WB Outdoor: 40 C DB 3 rd Step Interpolation of Outdoor DB Find TC, SC for (a) Indoor: 23 C DB, 15 C WB Outdoor: 37 C DB 25

11. INSTALLATION PRELIMINARY SITE SURVEY Electrical supply and installation is to conform to local authority's codes and regulations. (e.g. National Electricity Board). Voltage supply fluctuation must not exceed +/- 10% of rated voltage. Electricity supply lines must be independent of welding transformers which can cause high supply fluctuation. Ensure that the location is convenient for wiring and piping. INSTALLATION OF INDOOR UNIT The indoor unit must be installed such that there is no short circuit of the cool discharge. Comply to the installation clearance recommended. Do not put the indoor unit where there is direct sunlight on unit. Make sure the location is suitable for piping and drainage. Precautions steps : i) Use the hanger supplied with the unit. ii) Ensure the support is strong enough to withstand the weight of the unit. 800.0 800.0 800.0 PIPINGS Do not use contaminated or damaged copper tubings. If pipings, evaporator or condenser are exposed or had been opened for 15 seconds or more, vacuum and purge with field supplied refrigerant. Generally, do not remove plastic/rubber plugs/caps from fittings, tubings and coils until ready to connect suction or liquid line into fittings. OPERATIONAL CHECK After all electrical wiring is completed and the system is charged with refrigerant, make sure unit is operating properly. Check that: a) Condenser fans are running, with warm air blowing off the condenser coil. b) Evaporator blowers are running and discharging cool air. c) Suction line inside condensing unit feels cool. d) Liquid line inside condensing unit feels warm. ELECTRICAL CONNECTION As wiring regulations differ from country to country, please refer to your LOCAL ELECTRICAL CODES for field wiring regulations and ensure that these are complied with. Besides, observe the following general precautions: a) Ensure that the rated voltage of the unit corresponds to that of the name plate before commencing wiring work. b) Provide a power outlet to be used exclusively for each unit. A power supply disconnect and a circuit breaker for over-current protection should be provided in the exclusive line. c) The unit must be GROUNDED to prevent possible hazard due to insulation failure. d) All wiring must be firmly connected. e) Electrical wiring must not touch the refrigerant piping, compressor and any moving parts of the fan motors. 40

SPECIAL PRECAUTIONS WHEN DEALING WITH REFRIGERANT R40 7C UNIT 1) WHAT IS NEW REFRIGERANT R407C? R407C is a zeotropic refrigerant mixture which has Zero Ozone Depletion Potential (ODP = 0) and thus conformed to the Montreal Protocol regulation. It requires Polyol-ester oil (POE) oil for its compressor's lubricant. Its refrigerant capacity and performance are about the same as the refrigerant R22. 2) COMPONENTS Mixture weight composition R32(23%), R125(25%), R134a(52%) 3) CHARACTERISTIC R407C liquid and vapor components have different compositions when the fluid evaporates or condenses. Hence, when leak occurs and only vapor leaks out, the composition of the refrigerant mixture left in the system will change and subsequently affect the system performance. DO NOT add new refrigerant to leaked system. It is recommended that the system should be evacuated thoroughly before recharging with R407C. When refrigerant R407C is used, the composition will differ depending on whether it is in gaseous or liquid phase. Hence when charging R407C, ensure that only liquid is being withdrawn from the cylinder or can. This is to make certain that only original composition of R407C is being charged into the system. POE oil is used as lubricant for R407C compressor, which is different from the mineral oil used for R22 compressor. Extra precaution must be taken not to expose the R407C system too long to moist air. 4) CHECK LIST BEFORE INSTAL LATION/SERVICING Tubing Refrigerant R407C is more easily affected by dust of moisture compared with R22, make sure to temporarily cover the ends of the tubing prior to installation Compressor oil No additional charge of compressor oil is permitted. Refrigerant No other refrigerant other that R407C Tools Tools specifically for R407C only (must not be used for R22 or other refrigerant) i) Manifold gauge and charging hose ii) Gas leak detector iii) Refrigerant cylinder/charging cylinder iv) Vacuum pump c/w adapter v) Flare tools vi) Refrigerant recovery machine 5) HANDLING AND INSTALL ATION GUIDELINES Like R22 system, the handling and installation of R407C system are closely similar. All precautionary measures; such as ensuring no moisture, no dirt or chips in the system, clean brazing using nitrogen, and thorough leak check and vacuuming are equally important requirements. However, due to zeotropic nature of R407C and its hydroscopic POE oil, additional precautions must be taken to ensure optimum and trouble-free system operation. a) Filter-dryer must be installed along the liquid line for all R407C air conditioners. This is to minimise the contamination of moisture and dirt in the refrigerant system. Filter-dryer must be of molecular sieve type. For a heat-pump system, install a two-way flow filter dryer along the liquid line. b) During installation or servicing, avoid prolong exposure of the internal part of the refrigerant system to moist air. Residual POE oil in the piping and components can absorb moisture from the air. 41

c) Ensure that the compressor is not expose to open air for more than the recommended time specified by its manufacturer (typically less than 10 minutes). Removed the seal plugs only when the compressor is about to be brazed. d) The system should be thoroughly vacuumed to 1.0 Pa ( 700mmHg) or lower. This vacuuming level is more stringent than R22 system so as to ensure no incompressible gas and moisture in the system. e) When charging R407C, ensure that only liquid is being withdrawn from the cylinder or can. This is to ensure that only the original composition of R407C is being delivered into the system. The liquid composition can be different from the vapor composition. R32/R125/R134 23% / 25% / 52% 33% / 33% / 34% Composition of R407C in vapour phase is different from liquid phase. f) Normally, the R407C cylinder or can is being equipped with a dip pipe for liquid withdrawal. However, if the dip pipe is not available, invert the cylinder or can so as to withdraw liquid from the valve at the bottom. Dip-pipe Invert cylinder without dip-pipe Liquid withdrawal g) When servicing leak, the top up method, commonly practiced for R22 system, is not recommended for R407C system. Unlike R22 where the refrigerant is of a single component, the composition of R407C, which made up of three different components, may have changed during the leak. Consequently, a top up may not ensure that the R407C in the system is of original composition. This composition shift may adversely affect the system performance. It is recommended that the system should be evacuated thoroughly before recharging with R407C. 42

12. SERVICING AND MAINTENANCE Warning Disconnect from Main Supply before Servicing the air conditioner The unit is designed to give a long life operation with minimum maintenance required. However, it should be regularly checked and the following items should be given due attention.

PRE-START UP MAINTENANCE (AFTER EXTENDED SHUTDOWN) - Inspect thoroughly and clean indoor and outdoor units. - Clean or replace air filters. - Clean condensate drain line. - Clean clogged indoor and outdoor coils. - Check fan imbalance before operation. - Tighten all wiring connections and panels. - Check for refrigerant leakage. 43

The design concept of the Condensing Unit is such that all servicing can be done from the front and side of the unit. Upon removal of front and side panel, all the electrical "terminal box", fan and motor assembly and compressor are easily accessible. Under normal circumstances, these outdoor units only require a check and cleaning of air intake coil surfaces once quarterly. However, if a unit is installed in area subjected to much oil, mist and dust, the coil must be regularly cleaned by qualified Air Conditioner Service Technicians to ensure sufficient heat exchange and proper operation. Otherwise, the systems life span might be shortened. CAUTION When the compressor is to be stopped for a long time, the crankcase heater should be energized for at least 6 hours before start of operation. Do not charge OXYGEN, ACETYLENE or other flammable and poisonous gases into the refrigeration cycle when performing a leakage test or an airtight-test. These types of gases are extremely dangerous, because explosion can occur. It is recommended that nitrogen or refrigerant be charged for these types of tests. CAUTION FOR USE Bear the following points in mind to safeguard against malfunction and breakdown. Do not stick rods or other objects through the air outlet during operation since this may result to damage or injury The air conditioner must not re-start within 3 minutes after shutdown. (These models are equipped with a crankcase heater with the compressor). Make sure the air conditioner is properly grounded by checking the ground terminal. MAINTENANCE For superb performance and lasting durability, please do not forget to conduct proper and regular maintenance. Cleaning The Outdoor Unit Heat Exchanger If you use your air conditioner for prolonged period of time, the outdoor unit heat exchanger will become dirty impairing its function and reducing the performance of the air conditioned. Consult your local dealer about the cleaning of the heat exchanger. 44
