Water leakage test
Pipe insulation
1.
Pour water to the hole for the drain test or drain pan of the
indoor unit as shown in the figure. (About 1ℓ)
2.
Make sure that draining is done properly by checking end
of the drain pipe.
3.
If water leakage occurs, check the horizontality of the
indoor unit, connection part of the drain hose/drain pipe
and take measure to stop the leakage.
• After connecting the drain pipe to the indoor unit,
you must perform leakage test.
If the drain test has not done properly, water may get
into the indoor and cause property damage.
• Empty the condensation water in the drain pan
before any repair/maintenance service.
• You must insulate refrigerant pipes, branch joints,
distribution header and the pipe connection part.
• Make sure to prevent any gap between the insulation
on the bent part of the pipes.
• Make sure that insulation is overlapped when
fixing it.
Indoor unit
Fix securely without
any gap.
Power and communication cable connection
Wiring Work
1.
Before wiring work, you must turn off all power source.
2.
Indoor unit power should be supplied through the
breaker ( ELCB or MCCB+ELB ) separated by the outdoor
power.
ELCB: Earth Leakage Circuit Breaker
MCCB: Molded Case Circuit Breaker
ELB: Earth Leakage Breaker
3.
The power cable should be used only copper wires.
4.
Connect the power cable{1(L), 2(N)} among the units within
maximum length and communication cable(F1, F2) each.
5.
Connect F3, F4(for communication) when installing the
wired remote control.
