3.5 Test Running

Preparation before connecting the power
(1) Power must not be connected if the installation work is not completed.
(2) Control circuit is correct and all the wires are firmly connected.
(3) Cut-off valves of the gas pipe and liquid pipe are open.
(4) The inside of the unit should be clean. Take irrelevant objects out if there
is any.
(5) After checking, re-install the front side plate.
Operation after connecting the power
(1) If all the above works are finished, power on the unit.
(2) If the outside temperature is more than 30°C, heating mode can't be
enabled.
(3) Make sure the indoor and outdoor units can run normally.
(4) If there's sound of liquid shock when the compressor is running, then stop
the air conditioner immediately. Wait until the electric heating belt is
heated enough, and then restart the air conditioner.
(5) Feel the air flow of the indoor unit to see if it is normal.
(6) Press the swing button or speed control button on remote control or wired
control to see if the fan can run normally.
NOTICE
① If you use remote control to turn off the unit, compressor will continue to
run for 6min.
② If you use remote control to turn off the unit and then immediately turn the
unit on again, compressor will need 3min to restart. Even if you press
"ON/OFF" button on the remote control, it won't be started up right away.
③ If there's no display on the wired control, it's probably because the
connection wire between the indoor unit and wired control is not connected.
Please check again.
