Working principle and special functions for heating

Principle:

Defrosting:

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 32 , the
indoor unit microcomputer will stop compressor running and protect the unit.

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.

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.

Notices for use

Anti-cool wind function:

In "Heat" mode, under the following three kinds of state, if indoor heat exchanger doesn't
arrive at certain temp., indoor fan will not act, in order to prevent cool wind blowing(within
2 mins):

1. Heating starts. 2.After Auto Defrost finished. 3.Heating under the low temperature.

The operating temperature range (outdoor temperature) for cooling unit is 21℃~ 43℃；
for cooling and heating unit is -7℃~43℃.

Introduction of DC solar power management

The out-door unit can handle DC solar power input besides AC power input. If the solar
power device (poly-crystalline solar panel for instance) were connected to out-door unit,
the unit would preferentially consume the solar power. And the AC power would be
synchronously consumed as complement. The rated voltage of DC solar power should
be less than 165V and the rated current should be less than 10A.

Volatile liquid (e.g. thinner or gasoline) will damage the air conditioner. (So wipe the units with a
dry soft cloth, or a cloth slightly moistened with water or cleanser.)

Clean the front panel

Clean the air filter (Recommended once every three months)

NOTE: If dust is much more around the air conditioner, the air filters should be cleaned many times.
After taking off the filter, don't touch the fin of indoor unit, in order to avoid hurt your fingers.

Take down the air filter

At the slot of surface panel to open an angle, pull the air filter

Turn main power off.

Clean the filter and indoor and outdoor units' bodies.

Clear dust and obstructions from the outdoor unit.

Repaint the rubiginous place on the outdoor unit to prevent it from spreading.

Adopt the special shield to cover the outdoor unit, avoid the rain water, dust enter into
the unit and get rust.

Troubleshooting

CAUTION

Don't attempt to repair the air conditioner by yourself, it can cause an electric shock or
fire. Please check the following items before asking for repair, it can save your time and
money.

Phenomenon

Troubleshooting

Not operate immediately when the air
conditioner is restarted.

There's unusual smell blowing from the outlet
after operation is started.

The unit has no peculiar smell by itself. If has,
that is due to the smell accumulated in the
ambient.

Solution method: Cleaning the filter.
If problem still has, so need to clean air
conditioner. (Please contact with the authorized
maintenance center.)

Sound of water flow can be heard during
the operation.

The air conditioner is started, when it is
running the compressor started or stopped
running, or the unit is stopped, sometimes
there is swoosh or gurgle, the sound is due
to refrigerant flowing they are not malfuncti­ons.

In COOL mode, sometimes the mist emitted
from the air outlet vent.

When the indoor temperature and humidity
are very high, this phenomenon would
happen. This is caused by the room air is
swiftly cooled down. After running for a while,
indoor temperature and humidity will fall
down, the mist will die away.

Creaking noise can be heard when start or
stop the unit.

This is caused by the deformation of plastic
due to the changes of temperature.

Install the rear panel

1.Always mount the rear panel horizontally. Due to the water tray of indoor unit has been adopted the
both-way drainage design, the outlet of water tray should be adjusted slightly down when installing, that is
taking the outlet of the water tray as the center of a circle, the included angle between the evaporator and
level should be 0 or more, that is good for condensing water drainage.

2.Fix the rear panel on the wall with screws.
(Where is pre-covered with plastic granula)

3.Be sure that the rear panel has been fixed
firmly enough to withstand the weight of an

adult of 60kg, further more, the weight should
be evenly shared by each screw.

Install the piping hole

1.Make the piping hole (Ф55) in the wall at a slight downward slant to the
outdoor side.

2.Insert the piping-hole sleeve into the hole to prevent the connection piping
and wiring from being damaged when passing through the hole.

Install the water drainage pipe

1.For well draining, the drain hose should be placed at a downward slant.

2.Do not wrench or bend the drain hose or flood its end by water.

Mechanical Installation

1. Mechanical Installation of PV-modules should be operated by professional solar photovoltaic installation
guides or reputable solar installer or systems integrator.

2.

SC

do not provide any mechanical installation guide of PV-modules, as a result, SC will not provide

any instructor or after service for the problems of mechanical installation of PV-modules.

Electrical Installation

1. General Installation

• Any hardware used must be compatible with the mounting structure material to avoid galvanic corrosion

• It is not recommended to use modules with different configurations in the same system.

• Several modules should be connected in series to form a string of modules if needed.The maximum

number of series connected modules is 5.

• MC-4 connector is the recommended connector and the recommended system wires size is AWG12 .

2. Installation Sketch

Here we suggest to

install a DC current
breaker,so the user

can cut off the solar
power when not using
the air-conditioner for
a long time.

Assembly of PV-wire

1.The PV-wire should be single-pole, double insulated solar cable, the length of which is due to the
distance from PV-modules to outdoor unit of AC, the recommended conductor cross section is
AWG12, and it should accord with UL4703.

Assembly of MC-4 Connector

2. The MC-4 Connectors should be assembled to the PV-wires , and the other side of the PV-wires
should be assembled with spade terminals.

1. Introduction of MC-4 Connector
The MC-4 Connector contains three Parts, male PV cable coupler(PV-KST4/6II-UR), female PV cable
coupler(PV-KBT4/6II-UR) and a safty lock clip(PV-SSH4).
