Otherwise, itwill cause electrical shock.2) Engage authorized dealer or specialist for installation. Defective installation will cause electrical shockor fire.3) Strictly follow this installation instruction when doing installation work. Defective installation will causeelectrical shock or fire.4) Use the attached accessories parts and specified parts for installation. Otherwise, it will causeelectrical shock or fire.5) For electrical work, follow local national wiring standard, regulation and this installation instruction.Otherwise, it will cause electrical shock or fire.6) Wire routing must be properly arranged so that control board cover is fixed properly. If control boardcover is not fi xed properly, it will cause electrical shock or fire.7) Do not modify the length of Optional PCB lead wires. Otherwise, it will cause abnormal operation,electrical shock or fire.8) Do not touch the Optional PCB once the power supply is turn on. Accidental contact with the OptionalPCB will cause electrical shock.Optional PCB InstallationBefore installing the Optional PCB, steps below need to be carried out to remove the exterior chassis.WARNINGBe sure to switch off all the power supply (i.e. indoor power supply, heater power supply, boilertank power supply) before performing the steps below to avoid electrical shocks, etc.Step 1: Removal of the Cabinet Front PlatePlease follow the steps below for take out front plate. Before removing the front plate of indoor unit, alwaysswitch off all power supply (i.e. indoor unit power supply, heater power supply and Tank Unit power supply).1. Remove the 2 mounting screws which located at bottom of the front plate.2. Gently pull the lower section of the front plate towards you to remove the front plate from left and righthooks.3. Hold the left edge and right edge of front plate to lift up front plate from hooks.HookLift upScrewsStep 2: Open the Control Board CoverPlease follow the steps below to open control board cover. Before opening the control board cover ofindoor unit, always switch off all power supply (i.e. indoor unit power supply, heater power supply and TankUnit power supply).1. Remove the 6 mounting screws at the control board cover.2. Swing the control board cover to the right hand side.ScrewsScrewsCAUTIONStep 3: Installing the Optional PCB 1 onto the Control Board1.
