6.Final Checks
After having installed the unit, check that:
(1)The unit is fixed securely.
(2)The unit is installed properly.
(3)The drain pipe is provided with a drain trap.
(4)The electrical wiring has been connected correctly and the terminal screws have been properly tightened.
(5)The duct work has been performed correctly.
7.Trial Operation
(1)Before turning the unit on, measure the resistance between the terminals of the electrical parts and ground with a 500V megger and check that the value is at least 1MΩ . If the measured value is below 1MΩ , do not operate the unit.
(2)Check the operation of the high pressure switch by activating it. Operation should stop when the two leads of the outdoor unit fan motor are removed from the contactor and cooling continues for 5~10min.
(3)Check that the indoor and outdoor fans are rotating in the proper direction.
(4)After having checked the above points, proceed with a trial operation of the unit.
