Electric Circuit
WARNING
1)
Be sure to turn off all power supply before installing and connecting the Optional PCB. Otherwise, it
will cause electrical shock.
2)
Engage authorized dealer or specialist for installation. Defective installation will cause electrical shock
or fi re.
3)
Strictly follow this installation instruction when doing installation work. Defective installation will cause
electrical shock or fi re.
4)
Use the attached accessories parts and specifi ed parts for installation. Otherwise, it will cause
electrical shock or fi re.
5)
For electrical work, follow local national wiring standard, regulation and this installation instruction.
Otherwise, it will cause electrical shock or fi re.
6)
Wire routing must be properly arranged so that control board cover is fi xed properly. If control board
cover is not fi xed properly, it will cause electrical shock or fi re.
7)
Do not modify the length of Optional PCB lead wires. Otherwise, it will cause abnormal operation,
electrical shock or fi re.
8)
Do not touch the Optional PCB once the power supply is turn on. Accidental contact with the Optional
PCB will cause electrical shock.
Optional PCB Installation
Before installing the Optional PCB, steps below need to be carried out to remove the exterior chassis.
WARNING
Be sure to switch off all the power supply (i.e. indoor power supply, heater power supply, boiler
tank power supply) before performing the steps below to avoid electrical shocks, etc.
Step 1: Removal of the Cabinet Front Plate
Please follow the steps below for take out front plate. Before removing the front plate of indoor unit, always
switch 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 right
hooks.
3.
Hold the left edge and right edge of front plate to lift up front plate from hooks.
