Others and Test Run

1. Marks for connecting units
When install multi-air condition system, in order to make clear of the connecting relation between outdoor unit and
each indoor unit, make a table on cover of electric box to indicate names of each indoor unit connected. (As follow)
2. Test run
Before test run
Make sure if the resistor between terminal row (Terminal L, N) of power supply and grounding point is over 1M*
by using mega-ohmmeter (500v) before switch on.
If less than 1M* , operation cannot be executed.
Switch on outdoor unit. Electrify the shell body of the compressor. In order to protect the compressor, electrify 12
hours before operation.
It is strictly forbidden to oblige test run with canceling protecting device by hands.
(Because no work of protect device is very dangerous)
Method of test run
When running test, please refer to instructions of operation and performance simultaneous.
In case of failing to start up in common way because of room temperature, test run can be executed through outdoor
unit.
Method of installation and trial run
