M5MSY-2010 Features

FeaturesSelf Diagnosis

The microprocessor provides the possibility to detect and diagnose any fault or malfunction that occurs in thesystem. The error will be refl ected by the blinking of the LED lights.

Advance Technology

Incorporating fuzzy logic control enables greater fl exibility in system control handling to achievePowerful, effi cient and economical operation.Even room temperature control.Constant and quiet compressor operation.Enhanced system reliability and reduced maintenance costs.

On / Off Button on Indoor Unit

On/Off button is provided on the front panel of the unit. It can be used when the remote controller is missing or if its battery has run out. (Note: This button can also be used for forced operation mode)

Wireless Remote Controller

The compact LCD transmitter is able to operate the air conditioner unit within the distance of 8 meters.Fan speed can be set at high / medium / low / super low or automatic.Sleep mode auto control will gradually increase or decrease the setting temperature to provide a comfortable surrounding for sleeping.Air fl ow direction can be controlled automatically.Room temperature is controlled by electronic thermostat.The real time timer allows the air conditioner to be switched On and Off automatically based on usersettings.Turbo mode function is available to enables the required set temperature to be achieved in a short time.Personalized Setting allows user to preset and store 2 groups of personal settings (including timer setting)in the handset.

Higher Energy Savings

The inverter compressor is programmed to run at the optimum speed. This is controlled by input frequency that varies according to the indoor load requirements.Once the indoor set temperature is achieved, the input frequency supply to the compressor will be reduced. Hence, less power is required to maintain the unit operation and this will consume less energy.

Improved Compressor Life Span

For this multi-split inverter system, once the unit is started, the compressor rotation speed is steadily ramp up or down based on load requirement throughout the operation. This control method gives the compressor motor a smooth operation. It helps to reduce the wear and tear of the compressor motor. In the long run, the life span of compressor is increased.

Overheating Protection (for heat pump unit only)

In case the internal and/or the external temperature are too high, or the fi lter is dirty and clogged up, therefrigerant may be overheated. The compressor will reduce its running speed in order to lower the temperature of heat exchanger. If the temperature is still very high, the compressor will stop.

Sealing MaterialIt is possible to seal one of the four air discharge outlet (sealing two or more air discharge outlet could cause a malfunction).Remove the front panel and inserting the seal material into the air discharge outlet at the indoor unit to sealthe air outlet.The sealing material is the same length as the length air discharge outlet. If it is desired to seal the shorter air discharge outlet, cut the sealing material to shorten it.Push the sealing material in about 10mm beyond the bottom surface of the indoor unit so that it does not touch the air louver. Be sure not to push the sealing material in any farther than about 10mm.

Short Duct Specifi cation For M5CKY-E Unit

The indoor unit is provided with air discharge and air intake “knock-out” hole for duct connection. However the connection of the short duct for air discharge is possible on only one side.The use of short duct for air discharge will improve air fl ow distribution if there is an obstruction (such as alighting fi xture) or in a long, narrow room or an L-shaped room. It is also used for air-conditioning of two rooms simultaneously.

Inspect thoroughly and clean indoor and outdoor units.Clean or replace air fi lters.Clean condensates drain line.Clean clogged indoor and outdoor coils.Check fan imbalance before operation.Tighten all wiring connections and panels.Check for refrigerant leakage.

Outdoor ModelsThe design of the M5MSY outdoor series allows servicing to be carried out easily. The removal of the top, front and side panels makes almost every part accessible. Under normal circumstances, these outdoor units only require a check and cleaning of air intake coil surface once every 3 months. However, if a unit is installed in areas subjected to much oil mist and dust, the coils must be regularly cleaned by qualifi ed Air Conditioner Service Technicians to ensure suffi cient heat exchange and proper operation. Otherwise, the systems life span may be shortened.

Caution

Do not charge OXYGEN, ACETYLENE OR OTHER FLAMMABLE and poisonous gases into the unit when performing a leakage test or an airtight test. These gases could cause severe explosion and damage if exposed to high temperature and pressure.It is recommended that only nitrogen or refrigerant be charged when performing the leakage or airtight test.
