9 2-3. CONNECT THE DRAIN HOSE 2-4. FLOODING DRAINAGE Do not install the washer where it is directly exposed to sunlight, wind, rain, etc. Plug the power cord of this washer into a properly installed standard power outlet that is grounded. Your machine requires a floor drainage slope (or hole) that will SAFELY DISPOSE of the FULL FLOW of any water that may leak out should the machine malfunction.It is therefore the OWNER’S RESPONSIBILITY to make sure this machine is installed in an area with a drain hole (or slope) that will prevent any possibility of water damage to floor coverings or property. Permissible water temperature : Max 70 ˚C (160 ˚F) Permissible water pressure : Max 116psi (800 kpa, 8 kg /cm 2 ), Min 4 psi (30 kpa, 0.3 kg/cm 2 ) If water temperature and pressure are greater than above, it may cause damage to the machine. If you have uncontrolled water temperature and pressure you should fit a temperature and pressure relief valve to ensure that water temperature and water pressure remain within the safe limits. Consult a plumber or electrician if you are unable to adjust water temperature and pres sure. Do not over tighten the coupling nuts with a tool.Inlets are plastic : Do not strip or crossthread. Cable Tie 0.9~1.2m 0.9~1.2m Cable Tie Connect the drain hose to the outlet of the drain pump located at the rear of the washing machine. Attach the clip to the drain hose. And then push it toward the body of the washing machine as indicated by the arrow. Check that the drain hose is hung up over the edge of the laundry tub. Do not use an extension hose. NOTE : Never lay down the drain hose, as water will be discharged. Be sure the drain hose is properly routed so it will not kink or lift from the sink. The discharge height should be approximately 0.9 ~1.2 m from the floor. Connect the drain hose adjusting the length of it not to be dropped. If drain hose is dropped the drainage could be poor because of blockage in the hose. You machine requires a floor drainage slope (or hole)that will SAFELY DISPOSE of the FULL FLOW of any water that may leak out should the machine malfunction. It is therefore the OWNER'S RESPONSIBILITY to make sure this machine is installed in an area with a drain hole (or slope)that will prevent any possibility of water damage to floor coverings or property.
