Easy Maintenance The simple design concept has maintenance and servicing in mind. Access to the internal parts of the unit
can be from front or back of the unit by removing a few screws
Filter Rack The fan coil unit has a filter rack to hold the air filter. This ensure the air flow is clean and the filter is easily
accessible for maintenance and cleaning
Three Speed Motor The unit has 3-speed direct driven centrifugal fan and operate very silently to give whisper comfort condition. The speed of the fan can be adjusted through the electric controller. (See below).
Easy and Flexible Installation The easy is highly compact and therefore it is very easy to select a location to install the unit such that only small space is required.
Electric Controller
Electric Controller can display cool, dry and fan mode with auto, high, medium and low fan speed. The temperature settings range from 16 OC and 30 OC.

Preliminary Site Survey a) Electrical supply and installation is to confirm to local authoritys (e.g. National Electricity Board) codes
and regulations. b) Voltage supply fluctuation must not exceed +/- 10% of rated voltage. 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.
Piping Do not use contaminated or damaged copper tubing. If piping, 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, tubing and coils until ready to connect suction or liquid line into fittings.
Operational Check After all electrical wiring is completed and 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.

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 Max. Elevation,
m (ft)
Max. Length,
m (ft)
Max. Total Length, m (ft)
Max. of
Bends
MLC 30C 25 (82.0) 20 (65.6) 45 (147.6) 8
MLC 40C 25 (82.0) 20 (65.6) 45 (147.6) 8
MLC 50C 25 (82.0) 20 (65.6) 45 (147.6) 8
MLC 61C 25 (82.0) 20 (65.6) 45 (147.6) 8
COUTION: 1) Our guarantee on the performance of our air-conditioners is strictly revoked if the height, length
and/or the number of bends of the refrigerant piping system installed is beyond the limit above. 2) Bending must be carefully made so as not to crush the pipe. Use a pipe bender to bend a pipe as far
as possible.
