(3). How to fix connection cord and power cord by cord clamp
After passing the connection cord and power cord through the insulation tube, fasten it with the
cord clamp.(Fig.41)
① . Before starting work, check that power is not being supplied to the indoor unit and outdoor unit.
② . Match the terminal block numbers and connection cord colors with those of the indoor unit side.
③ . Erroneous wiring may cause burning of the electric parts.
④ . Connect the connection cords firmly to the terminal block. Imperfect installation may cause a fire.
⑤ . Always fasten the outside covering of the connection cord with cord clamps. (If the insulator is not
clamped, electric leakage may occur.)
⑥ . Always connect the ground wire.
