Compressor ON Temp.	Setting Temp.
Compressor OFF Temp.	Setting Temp.+3°C

•While in compressor on, the indoor fan is off when the indoor pipe temp. is below 20°C, when above 28°C , it operates with the low or setting airflow speed. When the indoor pipe temp is between 20°C and 28°C, it operates with Super-Low(while in sleep mode, with the medium airflow speed).

•While in compressor off, the indoor fan is off when the indoor pipe temp is below 33°C, when above 35°C , it operates with the low airflow speed.

•If overloaded while in heating mode operation, in order to prevent the compressor from OLP operation, the outdoor fan is turned on/off according to the indoor pipe temp.

•While in defrost control, the minimum temp of the indoor pipe is measured and it is compared with the present temp of the indoor pipe to get the difference of the indoor pipe temperatures (=the present temperature of the indoor pipe ? the minimum temperature of the indoor pipe). When the difference is 5°C or higher, defrost control is completed and heating mode operation is carried out.

•While in defrost control, if the defrost time determined before the start of defrost control is completed, defrost control stops and heating mode operation is carried out regardless of the above condition.

•When the indoor pipe temp is 42°C or above, defrost control is not carried out even if the condition is one of the defrost conditions above.

3) How to fix installation plate

The wall you select should be strong and solid enough to prevent vibration

1. Mount the installation plate on the wall with four type A screws. If mounting the unit on a concrete wall, use anchor bolts.

•Mount the installation plate horizontally by aligning the centerline using a level.

Installation Plate

Type "A" screw

2.Measure the wall and mark the centerline. It is also important to use caution concerning the location of the installation plate-routing of the wiring to power outlets is through the walls typically. Drilling the hole through the wall for piping connections must be done safely.

4)Drill a hole in the wall

•Drill the piping hole with a ø 70mm hole core drill. Drill the piping hole at either the right or the left with the hole slightly slanted to the outdoor side.

2. Flaring Work and Connection of Piping

1) Flaring work

Main cause for refrigerant leakage is due to defect in the flaring work. Carry out correct flaring work using the following procedure.

1.Cut the pipes and the cable.

•Use the piping kit accessory or pipes purchased locally.

•Measure the distance between the indoor and the outdoor unit.

•Cut the pipes a little longer than the measured distance.

•Cut the cable 1.5m longer than the pipe length.

4.Flaring work

•Firmly hold copper pipe in a die in the dimension shown in the table above.

		"A"	Handle
	Bar		Bar
			Yoke
			Cone

Copper pipe

Clamp handle

Red arrow mark

Copper		Slanted Uneven Rough
pipe	90°

2.Burr removal

•Completely remove all burrs from the cut cross section of pipe/tube.

•Put the end of the copper tube/pipe in a downward direction as you remove burrs in order to avoid dropping burrs into the tubing.

Reamer

Point down

3.Putting nut on

•Remove flare nuts attached to indoor and outdoor unit, then put them on pipe/tube having completed burr removal.

(not possible to put them on after flaring work)

Flare nut

Copper tube

•Carry out flaring work using flaring tool as shown below.
