minutes later.

Afterheat

After the finishing of HEATING operation, the airflow from indoor unit is discharged 2-5
minutes.

Defrost

In HEATING operation the appliance will defrost (de-ice) automatically to raise efficiency.
This procedure usually lasts 2-10 minutes. During defrosting, fans stop operation.
After defrosting completes, it returns to HEATING mode automatically.

Note: Heating is NOT available for cooling only air conditioner models.

If the plug is not properly plugged.

If batteries in the remote controller exhausted.
If the protective device works to protect the appliance.

If the protector trip or fuse is blown.

Are the intakes and outlets of the air conditioner
blocked

Is the temperature set properly

Is the air filter dirty?

If strong interference(from excessive static electricity
discharge, power supply voltage abnormality)presents,
operation will be abnormal. At this time, disconnect

Installation Instructions

Indoor Unit Installation

1. Installing the Mounting Plate

Decide an installing location for the mounting plate according to the indoor unit location and piping direction.

. Keep the mounting plate horizontally with a horizontal ruler or dropping line.

Drill holes of in depth on the wall for fixing the plate.1"
Insert the plastic plugs to the hole, fix the mounting plate with tapping screws.

Inspect if the mounting plate is well fixed. Then drill a hole for piping.

Note: The shape of your mounting plate may be different from the one above, but installation method is similar.

2. Drill a Hole for Piping

Decide the position of hole for piping according to the
location of mounting plate.

Drill a hole on the wall. The hole should tilt a little
downward toward outside.

Install a sleeve through the wall hole to keep the wall
tidy and clean.

3. Indoor Unit Piping Installation

Put the piping (liquid and pipe) and cables through the wall hole from outside or put them through
from inside after indoor piping and cables connection complete so as to connect to outdoor unit.
Decide whether saw the unloading piece off in accordance with the piping direction.(as shown below)

Connecting the refrigerant lines between the indoor& outdoor units

Note that since the refrigerant metering device is located in the outdoor unit,both refrigerant
lines must be insulated with a minimum of 3/8 foam along the entire length.

Gently bend the line set stubs from the indoor unit to the desired location and the using 2 box
end or adjustable wrenches,remove the flare nuts from the indoor unit line stubs.The indoor
unit is charged with a dry gas.If you do not hear the release of pressure when removing the
flare nuts,it is possible that the evaporator section(indoor unit)has developed a leak and you
should contact your dealer for a replacement indoor unit.Note:Using a small amount of
vacuum pump oil on the male flare threads will ease installation.Snug the line set to the stubs
using the 2 wrenches-one wrench on the male fitting and one wrench on the female fitting.

1). Remove the access door from the unit by loosening
the screw. Connect the wires to the terminals on the
control board individually as the following.

2). Secure the power connecting cord onto the control
board with cable clamp.

3). Reinstall the access door to the original position
with the screw.

4) Use a recognized circuit breaker for 24K.30K model
between the power source and the unit. A disconnecting
device to adequately disconnect all supply lines must be
fitted.

Caution:

1. Never fail to have an individual power circuit specifically for the air conditioner. As for the
method of wiring, refer to the circuit diagram posted on the inside of the access door .

2.Comfirm that the cable thickness is as specified in the power source specification.
(See the cable specification table below)

3.Check the wires and make sure that they are all tightly fastened after cable connection.

4. Be sure to install an earth leakage circuit breaker in wet or moist area.

Outdoor Unit Installation

1.Install Drain Port and Drain Hose (for heat-pump model only)

The condensate drains from the outdoor unit when the unit operates
in heating mode. In order to protect the environment, install a drain

port and a drain hose to direct the condensate water. Just install the
drain port and rubber washer to the chassis of the outdoor unit, then
connect a drain hose to the port as the right figure shown.

2. Install and Fix Outdoor Unit

Drain port

Fix with bolts and nuts tightly on a flat and strong floor.

If installed on the wall or roof, make sure to fix the supporter well to prevent it

from shaking due to serious vibration or strong wind.

3. Outdoor Unit Piping Connection

Remove the valve caps from the 2-way and 3-way valve.

Connect the pipes to the 2-way and 3-way valves separately according to the required torque.

4. Outdoor Unit Cable Connection (see previous page)

Drain hose

Air Purging

The air which contains moisture remaining in the refrigeration cycle may cause a malfunction on the
compressor. After connecting the indoor and outdoor units, evacuate air and moisture from refrigerant
cycle using a vacuum pump, as shown below.

Installation Instructions

How to Purge Air Tubes

(1). Unscrew and remove caps from 2 and 3-way valves.

(2). Unscrew and remove cap from service valve.

(3). Connect vacuum pump flexible hose to the service valve.
(4). Start vacuum pump for 10-15 minutes until reaching a vacuum of Hg absolutes.30"
(5). With vacuum pump still running close the low pressure knob on vacuum pump manifold. Then stop

vacuum pump.
(6). Open 2-way valve 1/4 turn then close it after 10 seconds. Check tightness of all joints using liquid

soap or an electronic leak detector.

(7). Turn 2 and 3-way valves stem to fully the valves. Disconnect vacuum pump flexible hose.
(8). Replace and tighten all valve caps.

Test Running

Connect to the power source, check if the function selection keys on the remote controller are working

properly.
Check if the room temperature adjustments and timer settings are working properly.
Check if the drain is open.
Check if there is any abnormal noise or vibration during operation.
Check if there is leakage of refrigerant.

ATTENTION:

If there is no power plug along with the air conditioner,The power cord should be connected to an air
switch ,whose current carrying capacity should be more than 20A and the minimum open-circuit
distance among the live polar pole,the neutral polar pole and the ground polar pole should be more
than 1".If any malfuctions,please cut off the supply by the air switch and contact the manufacturer
or its service agent.

The appliance shall be installed in accordance with national wiring regulations.

If the supply cord is damaged. It is better to be replaced by the manufacturer or its service agent or a
similarly qualified person in order to avoid a hazard.

NOTENOTE

Please read this manual before installing and using it.

Do not let air enter the refrigeration system or discharge refrigerant when moving the air conditioner.

Test run the air conditioner after finishing installation, and record details of operation.

rating 3.15 A,250V;
rating 15 A,250V,for 18K,22K,24K is 65TS with rating 25A,250V.

The fuse for the whole unit is to be provided by the user according to the current at maximum power

input or use other over-current protective device instead.
