Fan motor
This component requires only a little care. As the motor is lubricated and sealed before the
equipment leaves factory, no more lubrication is needed. After the unit remains in service for
six months, be sure to check the fan motor is entirely insulated from the ground.
Heat exchanger
Clean the dust and foreign matters from the surface of heat exchanger using a cleaner together
with a nylon brush. Please note that there is no need to clean the surface if you use an
appropriate air filter and take proper care of the heat exchanger.
Fire damper
Please check the damper once every three months, to see if the fuse link is broken or has any
fallen blade, becomes flexible or even falls off, and if it functions well.
Drainpipe
Before the unit is running, check if the drain pipe is blocked, to ensure smooth discharge of
condensate water. As the condensate water is prone to bacteria, please check the water
collector around the end of each quarter, to see if it smells unusual. If so, put some medicine
containing algaecide and penetrant in the collector to prevent bacteria and slime.
Replacing parts
You can get parts from nearby dealers. Be sure to indicate the following information about the
parts you need: unit model, factory number, name and quantity.
For a unit equipped with a temperature controller, lease note the following:
Make sure the start switch is closed;
Press the ON button on the start switch;
Set the air-conditioner to your desired temperature;
The rotating speed of the fan is usually preset;
After the unit stops running, to restart the compressor, please wait at least 3 minutes
(except that the unit is equipped with a 3-minute relay) so as to protect the compressor;
Sometimes you may install an air output control unit to control the air volume.
Maintenance and care of indoor unit MCK
Although the air-conditioner is designed to have a long service life even with minimal care, be sure
to check it at regular intervals throughout its service, so that you can use the air-conditioner better.
