Please use pliers to pull out the drain cap. (This is an easier way to remove the drain cap). INSTALLATION OF REFRIGERATING PIPES AFTER CONNECTION The refrigerating pipes should be adjusted to fit into the hole on the wall and then ready for further connection. The terminals of 2 connected pipes must be covered with insulator used for terminal connection. Then the pipes are wrapped with insulation pipe. Connect the connecting cord after removing electrical cover. (Refer to “CONNECTION OF POWER CORD”) After adjustment, fit the connecting cord and pipes into the space available under the indoor unit. Use holder to hold them tight. ! CAUTION The rubber strap used for fixing the insulator should not be tied with great force. Otherwise, this will damage heat insulation and causes water condensation. Holder can be attached at the either of 2 places. Please select the easier position.
