Precaution & Installation Safety Precautions Before installing the air conditioner unit, please read the following safety precautions carefully. WARNING • Installation and maintenance should be performed by qualified persons who are familiar with local code and regulation, and experienced with this type of appliance. • All field wiring must be installed in accordance with the national wiring regulation.
Installation All series of air conditioners are designed for outdoor installations and are to be placed on a slab or rooftop. However, if the air conditioner is to be installed in a plant room, please contact your equipment supplier prior to installation for further advise. Access to the compressors, control wiring, and fans for service and installation purpose must be provided. Please see item 1: Space Required Around Units for recommendations. 1. Space Required Around Units.

2. Duct Construction. (1) Series MRT side flow units are equipped with horizontal supply and return air openings. Duct connection to the unit should be made with duct flanges and secured directly to the air openings with flexible duct connectors to avoid normal noise transmission. (2) For vertical air supply, a field supply plenum should be used. The figure shows the recommended method for duct connection. (3) To prevent air leakage, all duct seams should be taped.
3. Lifting Method. When the unit is to be lifted and moved, attach ropes to the hoisting hangers (4 pieces) provided on the top corners of the unit. When the unit is lifted, its center of gravity tends to shift the unit to one side. Imbalance such as that in the figure should be attained. The angles at which the ropes suspend the unit should be at least 60º at the compressor end and at least 45º at the condenser end. Care should be taken to avoid contact with the unit while it is being lifted. 4.
6. Optional Features (Down Flow) - Site Modification Required. Reconstruction Method. (From Side Flow To Down Flow) (For M(4)RT080/100/120/150/200A/AR Only) Series MRT side flow units are able to be modified to down flow in the field with the help of additional accessory items. The following diagrams show the necessary steps to reconstruct the unit from side flow to down flow. STEP 1 STEP 3 Remove top panel Re-install fan assy Re-install supply air cover Remove service panel STEP 2 2.
7. Special Precautions When Dealing With Refrigerant R407C Unit (1) What Is New Refrigerant R407C? R407C is a zeotropic refrigerant mixture which has Zero Ozone Depletion Potential (ODP = 0) and thus, conforms to the Montreal Protocol regulation. It requires Polyol-ester (POE) oil for its compressor’s lubricant. Its refrigerant capacity and performance are about the same as the refrigerant R22.
c) Ensure that the compressor is not exposed to open air for more than the recommended time specified by its manufacturer (typically less than 10 minutes). Remove 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.
8. Electric Wiring Construct The Earth Connection. All electrical work must be carried out by a suitable qualified electrical trades-person and in accordance with local supply authority requirements and associated regulators. The unit is to be wired directly from an electrical distribution board either by a circuit breaker (preferred) or HRC fuse. Fix power source wiring to control box by using buffer bushing for sensible force (PG connection or the like).

9. The Putting Condition Of The Belt 1. 2. 3. 4. Set the parallel angle of the fan and the motor pulley as shown in table 1 and figure 1. Set the tension of one belt when the flexion load is within the range as shown in figure 2 and table 2 at the proper flexion. (A=0.016xC mm) Adjust the suitable tension after the belt sit properly across the pulley (after working for 24-28 hours). When a new belt is used, adjust the suitable tension about 1.3 times the maximum value of the flexion load.
11. Before Operating The Unit 1. Check points for operation Check the following points before you operate your air conditioner. (1) Check that there is nothing blocking the flow of air from the air outlet into the air inlet. Indoor Side Outlet grille Outdoor Side Inlet grille Ceiling Obstacle blocking air outlet Ceiling Obstacle blocking air inlet (2) Make sure the air conditioner is properly grounded by checking the ground terminal.

Selection Process Drive Package The following are the design requirements for MRT100A unit: Model: MRT100A Supply Air Quantity = 3800 External Static Pressure = 150 Step 1: From the blower curve (at 3800 CFM), Standard operating system; Internal Static Pressure = 160 CFM Pa Pa Step 2: Therefore at 3800 CFM and 150 Pa external static pressure, Total Static Pressure = 150 + 160 Pa = 310 Pa Step 3: From the blower curve, the design requirement calls for RPM about 1200 RPM.

Servicing & Maintenance For Superior Performance And Lasting Durability, Please Do Not Forget To Conduct Proper And Regular Maintenance. 1.1 Warning 1.Do not wash the unit with water. If washed with water, electrical shock may be caused. 2.Turn off power source. For safety, turn the power source off before service work to avoid electronical shock. Cleaning The Saranet Filter The standard unit comes with a saranet filter.
1.5 When The Air Conditioner Is Not To Be Used For A Long Time If the air conditioner is not to be used for a long time due to seasonal change, etc., Please do the following work. 1. The power supply switch is turned off. If the power supply is kept on, several watts or several tends of watts will be wasted. The accumulation of dust, etc., can result in fire. 2. Filter, and drain pan must be cleaned. Pay attention to clean dust in the drain. 3.
2.4 Consideration Of The Noise (1) Take sufficient measures against noise when installing the air conditioners at hospitals or communications related businesses. (2) If the air conditioner is used in any of the above-mentioned environments, frequent operational failure can be expected. It is advisable to avoid these type of installation sites. For further details, consult with your dealer.
Troubleshooting Whena 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 Fault conditions The air conditioner unit will not resume after power failure.
By means of pressure readings: 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. Poor compression / no compression (compressor defective) 2. Reversing valve leaking. 1. 2. 3. 4. 5. 6. Undercharged with refrigerant. Refrigerant leakage. Air filter clogged / dirty (indoor unit). Indoor fan locked / seized. Defective defrost control, outdoor coil freeze up (heating).
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”.
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.
