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 application, please contact your equipment supplier prior to installation. Access for both service and installation must be provided to the compressors, control wiring and fans as shown below. 1. Space Required Around Units. (1) Care must be taken to prevent recirculation air.
MRT250/300 A/AR 2. Installation Of The Unit. (1) The figure shows the use of the roof curb available for mounting these units. (2) The curb should be sealed and fixed to the roof by weather stripping. A suggested means of sealing the unit and roof curb is shown below. 3. Duct Construction. (1) Series MRT side flow units are equipped with horizontal supply and return air openings.
4. Lifting Method. When the unit is to be lifted and moved, attach ropes to the suspension plates (4 p.c.s) provided on the top of the unit. When the unit is lifted, it is center of gravity tends to shift the unit one side and so balance, such as that in the figure below, should be attained. The angles at which the ropes suspend the unit should be at least 60° at the compressor end and at least 45 ° at the condenser end. Care should be taken to avoid contact with the main unit while carrying.
Special Precautions For R407C 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 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.
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.

Under this mode, press the respective MINUTE, HOUR and DAY key to select the time of the week when the air-conditioning unit is to automatically start running. Press the ON TIMER key again to save the setting. Press the OFF TIMER key to activate auto-OFF timer mode. Under this mode, press the respective MINUTE, HOUR and DAY key to select the time of the week when the air-conditioning unit is to automatically stop running.
iii) iv) Connect one end in each of the 4 wires to the terminal block behind the top case as shown below. The wire that goes into the "GND" terminal at the top case must be connected at the other end to the “GND" terminal at the main board. The same goes for the "+5V", "B" and "A" connection. Fasten back the top and bottom case into place. Hook the two upper claws into their respective slots and snap the lower part shut.
9. 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).

Servicing And Maintenance FOR SUPERIOR PERFORMANCE AND LASTING DURABILITY, PLEASE DO NOT FORGET TO CONDUCT PROPER AND REGULAR MAINTENANCE. Warning 1.Do not wash the unit with water. If washed with water, electrical shock may be caused. 2.Ahead of the maintenance. For safety, turn the power source off before service work. 1.
1.5 When The Air Conditioner Is Not To Be Used For Long Time. If the air conditioner is not to be used for a long time due to a 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. Also, the accumulation of dust, etc., can result in fire. 2. Filter, eliminator and drain pan are cleaned. Pay attention to throw dust in the drain. 3.
2.5 Disposing Of The Unit. When you need to dispose of the unit, consult your dealer. If pipes are removed incorrectly, refrigerant (fluorocarbon gas) may blow out and come into contact with your skin, causing injury. Releasing refrigerant into the atmosphere also damages the environments. 2.6 Maintenance And Inspection. (1) If the air conditioner is used throughout several seasons, inside can get dirty and eventually reduce the performance.
