Defrosting:
*
When outdoor temperature is low but high humidity, after a long while running, frost will
form on outdoor unit, that will effect the heating effect, at this time, the auto defrosting
function will act, the heat running will stop for 8-10mins.
*
During the auto defrosting, the fan motors of indoor unit and outdoor unit will stop.
*
During the defrosting, the indoor indicator flashes, the outdoor unit may
emit vapor, This is due to the defrosting, it isn't malfunction.
*
After defrosting finished,the heating will recover automatically.
The climate type of this unit is according to the nameplate.
Air conditioner absorbs heat in the room and transmit to outdoor and discharged, so that
indoor ambient temperature decreased, its cooling capacity will increase or decrease by
outdoor ambient temperature.
If the unit is running in COOL mode and in low temperature, there will be frost formed on
the heat exchanger, when indoor heat exchanger temperature decreased below 0 , the
indoor unit microcomputer will stop compressor running and protect the unit.
℃
Principle:
*
Air conditioner absorbs heat from outdoor and transmits to indoor, in this way to increase
room temperature. This is the heat pump heating principle, its heating capacity will be
reduced due to outdoor temperature decrease.
*
If outdoor temperature becomes very low, please operate with other heating equipments.
Anti-cool wind function:
In Heat mode, the following three kinds of status, if indoor heat exchanger hasn't achieve
certain temperature that indoor fan motor will not start, in this way to prevent blowing cool
wind (within 3mins):
1. Heat operation just startedup. 2. After Auto defrosting operation is finished.
3. Heating under low temperature.

USER' S MANUAL

The temperature should not be set lower than
what you need. This would result to increase
energy cost.
To distribute cool air through out the roon,
adjust air flow direction as shown by the
arrows (see picture) to diffuse cool air.
Clean the air filter every week for higher
efficiency. Close window and door while operating the unit
to prevent leakage of cooled air to save energy.
Draw close curtains or close glass windows
when cooling to prevent heat load from sun
light which may cause more electricity cost.
In case of ineffective ventilation,open the
window to ventilate the room air once in a
while but not too long since cooled air will be
uselessly drained out.

Precautions
Check electrical system(voltage and frequency).
Use the proper power supply indicated on the
unit to operate the airconditioner and only fuses
with specified capacity.Do not use pieces of wire
instead of fuse.
Turn off the airconditioner if ,while running,
electricity interference occurs.If the unit is not
to be used for a long time,cut off the power
supply main switch.
Do not insert objects into the air inlet or outlet
when the airconditioner is running as it may
cause damage or personal injury .Also pay
special attention when children are around.
Do not locate any obstacle against the air
flow direction of indoor and outdoor unit.
Inefficient performance or malfunction may re-
sult.
Do not channel the air flow directly at people,
especially infants,aged persons or patients. Do not locate a heater or any other heat source
close to the unit.The heat may deform plastic
parts.

Indoor unit
The indoor unit should be sited in a place where:
1) the restrictions on installation specified in the indoor
unit installation drawings are met.
2) both air intake and exhaust have clear paths met.
3) the unit is not in the path of direct sunlight.
4) the unit is away from the source of heat or steam.
5) there is no source of machine oil vapour (this may
shorten indoor unit life).
6) cool(warm) air is circulated throughout the room.
7) the unit is away from electronic ignition type fluorwscent lamps
(inverter or rapid stert type) as they may shorten the remote
controller range.
8) the unit is at least 1 metre away from any television or radio
set(unit may cause interference with the picture or sound).

3)For piping ,see Connecting the refrigerant pipe,under Indoor Unit Installation(1).
4)Allow space around the pipe for a easier indoor unit pipe connection.
Min.allowable length
The suggested shortest pipe length is 2.5m,in order to avoid noise from the outdoor unit and vibration.
(Mechanical noise and vibration may occur depending on how the unit is installed and the environment in which it is
used.)
