③. Strong heating operation
When it is very cold, especially the period of time after just turning on the heater, it is cold inside the vehicle
or sometimes there is frost, snow which needs removing, you should choose this operation. That is: choose
heating pattern, press “wind speed increasing button” to choose the highest wind speed, press “set increasing
button” to choose the highest temperature.
④. Weak heating operation
When it is slightly cold, especially the period of time after turning on the heater, the indoor temperature is
suitable or slightly warm, you should choose this operation. That is: choose heating pattern, press “wind speed
decreasing button” to choose the lowest wind speed, press “set decreasing button” to choose moderately low
temperature.
⑤. Dehumidification and defrosting operation
When it is damp (including the indoor vapor and sweat made by human) and indoor temperature is higher than
outdoor (including using heater), except the discomfort of dampness to human, a layer of frost will form on the
inner side of the glass which will affect the view. Now you should choose this operation.
There are two ways of this operation:
a. When it is moderate or slightly hot, choose “weak refrigeration operation” (see ② for details)
b. When it is slightly cold, choose defrost pattern ( will appear on the screen). At defrosting
pattern, the refrigeration amount is set by the program, it can not be adjusted and there’s no display;
the heating amount can be adjusted by operator according to requirements of the indoor temperature.
Other instructions
①. Machine set up: As long as you change the system operation pattern, the system will close the extrinsic
cycle air door automatically (enter internal circulation pattern). If operator has to use the extrinsic cycle
after changing the operation pattern or just start up, press .
②. The machine will automatically remember any patterns (expect circulation wind pattern) or the change of
set (including automatically remember the condition before shut down when turning off the machine),
when you use this pattern again, the machine will return to the last condition (including automatically
return to the condition before last shut down after start). It’s very convenient for the users, e.g when start
the machine in the afternoon, it will automatically return to the using condition of the shut down in the
morning.
Matters need attention
(1) For the air-conditioner cabinet with dust screen, the dust screen must be monthly cleaned, or it will be
jammed by the dust, so the air in the cab cannot swimmingly flow through the heat exchanger and the
air-condition effect will be worse.
(2) Under special conditions, (e.g damp or not too hot environment, dust screen jam, circulating port jam by
foreign materials), using strong refrigeration for a long time, you will feel the wind is becoming smaller or
even no wind, this is the representation of air conditioner vaporization and frosting. The frost on the vaporizer
surface blocks the passage of air flow which makes refrigeration worse. But this is not malfunction, now you
should stop refrigeration for a moment, remove the blocking materials, choose big wind and restart
