Working principle and special functions for heating
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(or display “H1”), 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.

CAUTIONS FOR INSTALLATION WHERE
200mm
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) Once refrigerant piping and drain piping connections are complete, fill in the gap of the through hole with putty. A gap
can lead to condensation on the refrigerant pipe, and drain pipe, and the entry of insects into the pipes.
4) Attach the front panel and front grille in their original positions once all connections are complete.
Flaring the pipe end
1)Cut the pipe end with a pipe cutter.
2)Remove burrs with the cut surface facing downward so that the chips do not enter the pipe.
3)Fit the flare nut on the pipe.
4)Flare the pipe.
5)Check that the flaring is properly made.
WARNING
1) DO not use mineral oil on flared part.
2) Prevent mineral oil from getting into the system as this would reduce the lifetime of the units.
3) Never use piping which had been used for previous installations. Only use parts which are delivered with the unit.
4) Do never install a drier to this R410A unit in order to guarantee its lifetime.
5) The drying material may dissolve and damage the system.
6) Incomplete flaring may cause refrigerant gas leakage.
Make sure that the
flare nut is fitted
The pipe end must
be evenly flared in
a perfect circle
Flare’s inner
surface must
be scratch-free

1)Use torque wrenches when tightening the flare nuts to prevent damage to the flare nuts and gas leaks.
Coat here with refrigeration oil
2)Align the centres of both flares and tighten the flares and tighten the flare nuts 3 or 4 turns by hand.
Then tighten them fully with the torque wrenches.
3)To prevent gas leakage, apply refrigeration oil on both inner and outer surfaces in the flare. (Use refrigeration oil for
R410A.)

Caution on piping handling
1)Protect the open end of the pipe against dust and moisture.
2)All pipe bends should be as gentle as possible. Use a pipe bender for
bending.
(Bending radius should be 30 to 40mm or larger.)

Selection of copper and heat insulation materials
When using commercial copper pipes and fittings, observe the
following:
1)Insulation material: Polyethylene foam
Heat transfer rate:0.041 to 0.052W/mK(0.035 to 0.045kca/(mh
Refrigerant gas pipe’s surface temperature reaches 110 max.
Choose heat insulation materials that will withstand this temperature.
2)Be sure to insulate both the gas and liquid piping and to provide insulation dimensions as below.

3)Use separate thermal insulation pipes for gas and liquid refrigerant pipes.
Be sure to
place a cap.
If no flare cap is
available,cover
the flare mouth
with tape to keep
dirt or water out.

Checking for gas leakage
1)Check for leakage of gas after air purging
2)See the sections on air purges and gas leak checks in
the installation manual for the outdoor unit.
Attaching the connection pipe
Check for leakage here
Apply soapy water and ch-
eck carefully for leaking gas.
wipe soapy water off after
the check is complete.
Attach the pipe after checking for gas leakage, described above.
1)Cut the insulated portion of the on-site piping, matching it up with the connecting portion.
2)Secure the slit on the refrigerant piping side with the butt joint on the auxiliary piping using the tape, making sure there
are no gaps.
3)Wrap the slit and butt joint with the included insulation sheet, making sure there are no gaps.

CAUTION
1)Insulate the joint of the pipes securely.
Incomplete insulation may lead to water leakage.
2)Push the pipe inside so it does not place undue force on the front grille.
Connecting the drain hose
Insert the supplied C drain hose into the socket
of the drain pan.
Fully insert the drain hose until it adheres to a
seat of the socket.

INSTALLATION INSTRUCTIONS
Installation of indoor unit
Live the sensor securing plate, remove the front metal plate cover, and connect the branch wiring to the terminal block.
1)Strip wire ends (15mm)
2)Mach wire colours with terminal numbers on indoor and outdoor unit’s terminal blocks and firmly screw wires to
the corresponding terminals.
3)Connect the earth wires to the corresponding terminals.
4)Pull wires to make sure that they are securely latches up, then retain wires with wire retainer.
CAUTION
1)Do not use tapped wires, stranded wires, extensioncords, or starburst connections, as they may cause overheating,
electrical shock, or fire.
2)Do not use locally purchased electrical parts inside the product. (Do not branch the power for the drain pump, etc, from
the terminal block.) Doing so may cause electric shock or fire.)

Check after installation
Items to be checked Possible malfunction Situation
Has it been fixed firmly?
Have you done the refrigerant leakage test?
Is heat insulation sufficient?
Does the unit drain well?
Is the voltage in accordance with the rated
voltage marked on the nameplate?
Is the electrical wiring and piping connection
installed correctly and securely?
Has the unit been connected to a secure earth
connection?
Is the power cord specified?
Has the inlet and outlet been covered?
Has the length of connection pipes and the
refrigerant charge been record?
The unit may drop,shake or emit noise.
It may cause insufficient refrigerating capacity.
It may cause condensation and dripping.

Configuration of connection pipe and additional volume of refrigerant
1. Standard length of connection pipe
5m、7.5m、8m
2. Min length of connection pipe
For the unit with standard connection pipe of 5m, there is no limitation
for the min length of connection pipe. For the unit with standard connection
pipe of 7.5m and 8m, the min length of connection pipe is 3m.
3. Max length of connection pipe
4. The calculation method of additional refrigerant oil and refrigerant charging
amount after prolonging connection pipe
After the length of connection pipe is prolonged for 10m at the basis of
standard length, you should add 5ml of refrigerant oil for each additional
5m of connection pipe.
The calculation method of additional refrigerant charging amount (on the
(1) Additional refrigerant charging amount= prolonged length of liquid pipe × additional
refrigerant charging amount per meter
(2) When the length of connection pipe is above 5m, add refrigerant according
to the prolonged length of liquid pipe. The additional refrigerant charging
amount per meter is different according to the diameter of liquid pipe. See Sheet 2.
