Features Save Energy This decentralized, year-round heating and cooling system consists of a two-pipe closed loop water circuit, through which non-refrigerated water circulates continuously throughout the building. Locating the piping within the building negates the need of for piping insulation. These systems achieve energy conservation by pumping heat from warm to cold spaces whenever they coexist anywhere within the building.
Microcomputer remote control The microcomputer remote control has following functions • Five optional operation modes (heat/cool/dry/fan/auto). • Fan speed can be set at high, medium, low and automatic. • Sleep mode automatically increase set temperature since temperature is lower at night thus achieving healthy sleep. • Microcomputer controlled thermostat precisely controls room temperature resulting in energy saving and increases comfort. • Hot start and hot keep mode do not supply air for 30 sec.

4) Others ó Each supply and return air must be fixed with supporting frame onto the ceiling of concrete prefabricate. The duct joint section should be sealed with glue. ó Returning air-box is suggested to be more than 150mm away from the side wall starting from outer edge of box. ó The obliqueness of level of drainage pipe should be taken into account about 1% degree. ó Drainage pipe should be wrapped with insulation fiber.
Installation of MCK unit Preliminary site survey ó Electrical supply and installation is to conform to local authorityʼs (e.g. National Electrical Board) codes and regulations. ó 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. ó Ensure that the location is convenient for wiring, piping and drainage.
Unit Installation ó Measure and mark the position for the hanging rod. Drill the hole for the angle nut on the ceiling and fix the handing rod. ó The installation template is extended according to temperature and humidity. Check on dimensions in used. ó The dimensions of the installation template are as same as those in the ceiling opening dimensions. ó When ceiling lamination work is not completed, be sure to fit the installation template to the indoor unit.
Drain Piping Work ó ó ó ó ó Drainpipe must be in downward gradient for smooth drainage. Avoid the drainpipe in up and down slope to prevent reversed water flow. During the drain piping connection, be careful not to exert extra force on the drain connector at indoor unit. The outside diameter of the drain connection at the flexible drain hose is 20mm. Be sure to execute heat insulation (polyethylene foam with thickness more than 8.0mm) on the drain piping to avoid the condensed water dripping inside the room.
Note : Install the front frame panel firmly to prevent cool air leakage which will cause condensation and water dripping Indoor Unit Cool Air Cool Air Air leak Air leak Ceiling Board Ceiling Board Panel Good Installation Bad Installation Air intake grille installation ó ó ó ó ó Before installed the air intake grille, be sure to fix the ionizer filter to the air filter. Fix the ionizer filter to the air filter with the black side on top and white side at bottom. Carefully clip on the ionizer filter frame.

Installation Of Outdoor Unit The location of the outdoor unit is very flexible, it can be installed in ceiling, stairs, toilet and out wall or other places. In order to operate the unit reliable, precaution steps: 1) Leave enough space for service person to perform maintenance of repair and provide sufficient room to make water, electrical connections. 2) The place can withstand the weight of the outdoor unit and isolate the noise and vibration.
Refrigerant Piping Work Refrigerant piping is important in particular. Refrigeration cycle of the split air conditioner is realized by the perfect piping work. Piping length and elevation If the piping is too long, both the capacity and reliability of unit will drop. As the number of bends increase, resistance to flow of refrigerant system increases, thus lowering cooling capacity and as a result the compressor may become defective. Always choose the shortest path and follow the recommendation as tabulated.
Piping Connection 1) Do not use contaminated or damaged copper tubing. If any piping, evaporator or condenser had been exposed or had been opened for 15 seconds or more, then vacuum and purge with field supplied refrigerant. Generally, do not remove plastic, rubber plugs and brass nuts from the valves, fittings tubing and coils until it is ready to connect suction or liquid line into valves or fittings.
5) If systemʼs refrigerant is leaked, recharge refrigerant referring to following diagram.
Piping Works & Flaring Technique ó Do not use contaminated or damaged copper tubing. If any pipings, evaporator or condenser had been exposed or had been opened for 15 seconds or more, then vacuum and purge with field supplied refrigerant. Generally, do not remove plastic, rubber plugs and brass nuts from the valves, fittings, tubing and coils until it is ready to connect suction or liquid line into valves or fittings.

Vacuuming And Charging Method Purging the piping and the indoor unit The outdoor unit is equipped by two 3-way refrigerating connecting valves. The suction valve is the larger one whereas the smaller one is the liquid valve. Both valves are supplied with service port valve for connection to a manometer. ó ó ó ó ó ó ó ó ó ó ó ó Remove the caps from the valve and the service port. Connect the center manifold gauge to the vacuum pump. Connect the manifold gauge to the service port of the 3-way valve.
Additional Charge The refrigerant is pre-charged in the outdoor unit. If the piping length is less than 5m, then additional charge after vacuuming is not necessary. If the piping length is more than 5m, then use the additional charge valve as in the table below.
Overall Checking Ensure that: ó The unit has been mounted solidly and rigid in position. ó The piping and connections are leak-proof after the charging. ó Proper wiring has been installed. Drainage check ó Pour some water into the left side of the drain pan (the drainage is at the right side of the unit). Test run: ó ó ó ó ó ó Conduct a test run on the unit after having perform the water drainage test and the gas leakage test.

Servicing And Maintenance Warning Disconnect from the main supply before servicing the air conditioner unit. SERVICE PARTS MAINTENANCE PROCEDURES Indoor air filter 1.Remove any dust adhered on the filter by using a vacuum cleaner or wash in lukewarm water (below 40 °C) with neutral cleaning detergent. 2. Rinse well and dry the filter before placing it back onto the unit. 3.Do not use gasoline, volatile substances or chemical to clean the filter. At least once every 2 weeks. More frequently if necessary.
Maintenance 1. Normal maintenance on all conditioners is generally limited to filter changes. Lubrication of the fan motor is not required but may be performed to extend motor life. Use sae-20 non-detergent electric motor oil. 2. Filter changes are required at regular intervals. The time period between changes will depend upon the project requirements. Some applications such as motels produce a lot of lint from carpeting and linen changes, and will require more frequent filter changes.
Cleaning & Flushing System 1. Prior to first operation of any conditioner, the water circulating system must be cleaned and flushed of all construction dirt and debris. If the conditioners are equipped with water shut off valves, either electric or pressure operated, the supply and return run outs must be connected together at each conditioner location. This will prevent the introduction of dirt going into the unit. 2. Fill up the system at the city water makeup connection with all air vents open.
Troubleshooting When any malfunction of the conditioner unit is noted, immediately switch off the power supply to the unit. Check the following fault conditions and causes for some simple trouble shooting tips. FAULT POSSIBLE CAUSES 1. The compressor does not start operation after 3 ó Protection against frequent starting. Wait for 3 to 4 minutes from starting the air conditioner unit. minutes for the compressor to start operate. 2. The air conditioner unit does not operate.
