HOW TO INSTALL REFRIGERATOR

3. When customer uses bottled water.

*If customer wants to use bottled water, extra pump should be installed as shown below.

1.The pump system should not be on the floor (it may cause noise and vibration). Securely fasten the inlet and outlet nuts of pump.

2.If there is any leakage after installation, cut the water tube at right angle and reassemble.

3.When put the water tube end into the bottle, leave a clearance between bottle bottom and water tube end.

4 Check water coming out and any leakage.

Caution : • If feed tube is more than 4m, less water will come out due to pressure drops.

•Use standard feed tube to prevent leaking.

■Outternal Filter

1. Filter Fixation
