Access to the internal part of the unit can be from either side of the unit by loosening a few screws. Only for model MDB 060B, 070B and 100B with additional servicing panel from bottom Flexibility In Installation MDB 040B - MDB 150B models come with standard horizontal air discharge whereas MDB 200B - MDB 750B models come with standard vertical air discharge. However, the range from MDB 125B - MDB 750B are designed to cater for either horizontal or vertical air discharge application. Versatility Multiple rooms can be cooled together at the same time by using just one unit of fan coil unit. Fresh Air For Healthy Living Fresh air can be introduced into the building through the design of fresh air intakes. This will help to improve the indoor air quality. Superior Air Distribution For Comfortable Living The conditioned air can be effectively distributed to every corner of the room through the ducting and this ensure a more pleasant environment for comfort living. Flexibility Of Air Supply McQuay MDB series using belt driven fan such as that the air volume and static required can be adjusted according to the requirement. This flexibility allow for wider application. 2 General Specifications Unit The casing is constructed with electro-galvanised mild steel sheet which provides a rigid cabinet. The internal components are easily accessible by removing the front panel. The finishing of the casing is a long-lasting epoxy polyester powder coating. Condenser Coil Each coil consists of staggered rows of 3/8" OD seamless copper tubes, mechanically expanded into die-formed corrugated aluminium fins. Each coil provided with integral sub-cooling circuit to maximize energy efficiency and promote superior match-system operating performance when connected to suitably sized DX Evaporator-blower unit. Coils are leak and pressure tested to 450 psig, evacuated and dehydrated. Condenser Fan and Motor The propeller fan is of acryl styrene resin construction, direct driven by weatherproof single phase PSC motor. Fan motor has class E insulation. Fan is protected with plastic outer nozzle. Compressor High efficiency, refrigerant-cooled, reciprocating/scroll hermetic compressor has internal suspension system to eliminate noise, vibration and further resiliently isolated from unit base. Compressor has internal overload protection. Units are provided with manual reset high-low pressure cut-outs and crankcase heater for off-cycle operation to guard against compressor valve plate damage during start-up. Compressor is covered with sound shield to further reduce noise level. Safety Controls Manual reset high pressure and low pressure cut-outs to guard against compressor damage due to high discharge head pressure and system leakage respectively. Crankcase heater for each compressor to prevent liquid migration, which can damage compressor valve plates, during off-cycle and eases start-up.

Electricity supply line must be independent of welding transformers which can cause supply fluctuation. c) Ensure that the location is convenient for wiring and piping. Mounting a) For ceiling mounted models, locate a position where piping and ducting work can be kept to a minimum. Ensure that overhead supports are strong enough to hold the unit’s weight. Position hanger rods and check for alignment with the unit. Check that hangers are secure and that the base of fan-coil unit is level in two horizontal directions. 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) b) c) d) Condenser fans are running, with warm air blowing off the condenser coil. Evaporator blowers are running and discharging cool air. Suction line inside condensing unit feels cool. 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. 54 Installation (outdoor) (outdoor) Location For Installation Of The Condensing Units As condensing temperature rises, evaporating temperature rises and cooling capacity drops. In order to achieve maximum cooling capacity, the location selected should fulfill the following requirements:a) Install the condensing (outdoor) unit in a way such that hot air distributed by the outdoor condensing unit cannot be drawn in again (as in the case of short circuit of hot discharge air). Allow sufficient space for maintenance around the unit. 55 b) Ensure that there is no obstruction of air flow into or out of the unit. Remove obstacle which block air intake or discharge. c) The location must be well ventilated, so that the unit can draw and distribute plenty of air thus lowering the condensing temperature. d) A place capable of bearing the weight of the outdoor unit and isolating noise and vibration. e) A place protected from direct sunlight. Otherwise use an awning for protection, if necessary. f) A place where the hot air discharge and operating sound level will not annoy the neighbors. g) The location must not be susceptible to dust or oil mist. CAUTION: If the condensing unit is operated in an atmosphere containing oils (including machine oils), salt (coastal area), sulphide gas (near hot spring, oil refinery plant), such substances may lead to failure of the unit. 56 Field Piping To ensure satisfactory operation and performance, the following points should be noted for the field piping arrangements of the complete refrigerant cycle. a) Liquid loops or oil traps must be provided according to the position of the outdoor and the indoor units (depending on whether the indoor unit is above or below the outdoor unit). b) Field supplied filter dryer should be provided as close to the expansion valve(s) of the indoor unit (evaporator) as possible. c) Field supplied sight glass must be assembled and mounted as shown in the figure. Maximum Pipe Length And Maximum Number Of Bends When the pipe is too long, the required refrigerant quantity increases. Both the capacity and reliability drops as a result. As the number of bends increases, system piping resistance to the refrigerant flow increases, thus lowering the cooling capacity and the compressor may become defective. If the height difference between the evaporator and the condenser is excessive, the cooling capacity drops, the lubricating oil return is retarded, affecting the compressor efficiency adversely. Always choose the shortest piping path and follow the recommendations as shown below : Model MMC 075B MMC 100B/BR MMC 125B/BR MMC 075C/CR MMC 100C MMC 150C Max. Elevation, m (ft.) 20(65.6) 20(65.6) 20(65.6) 20(65.6) 20(65.6) 20(65.6) Max.

Use a pipe bender to bend a pipe as far as possible. Maximum Allowable Piping Length & Elevation Difference 57 Installation Clearance A) For MMC – B/BR series (Single/Multiple Condensing Unit) When two or more outdoor units are installed in a location, they must be positioned such that one unit will not be taking the hot discharge air from another. This also applies when two or more units are installed one above the other. The units must all face the same direction or opposite direction (back to back), such that hot air short circuit does not occur.

The Series II Condensing Unit is provided with Quik Lok fittings and charging nipples. Vacuuming After the system pipings are properly connected, connect the flexible hoses to the correct charging nipples as shown in the diagrams. Ensure that flexible hose from charging nipples are connected to vacuum pump via standard servicing valves and pressure gauges (gauge manifold). Vacuum the air conditioner system to at least 500 microns Hg. Charging Before charging, the vacuum must be held at 500 microns Hg for at least 15 minutes, then break vacuum by charging R-22 refrigerant. Operate the unit for 15 minutes and ensure that refrigerant charges is of correct quantity by monitoring running current and suction and liquid line pressures. Suction and discharge pipe pressures should be in the region of 75 psig and 275 psig generally. After ensuring the system is correctly charged, remove flexible hose from charging nipples and replace caps. 59 Servicing and maintenance 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. 60 Operation Electrical Connection Wiring regulations about wire diameter differs from country to country. Please refer to your LOCAL ELECTRICAL CODES for field wiring rules. Be sure that installation comply with such rules and regulations. General Precaution Ensure that the rated voltage of the unit correspond to the name plate before carrying out proper wiring according to the wiring diagram.
