Creating a vacuum
Be sure to use the vacuum pump to create a vacuum of the 
connective pipe at the air side and liquid side concurrently.
Refrigerant replenishment
If the length is greater than the reference pipe, the refrigerant 
replenishment quantity for each system should be calculated 
through the formula obtained according to the actual length of 
pipe. 
Record the refrigerant replenishment quantity, actual length of 
pipe and the height difference of the indoor & outdoor unit onto 
the operation confirmation table of the outdoor unit in advance 
for future reference.
Electric wiring
Select the power supply capacity and wire size according to 
the design manual. The power cable of the air conditioner is 
generally thicker than the power cable of the motor. 
In order to prevent misoperation of the air conditioner, do not 
interleave or entwine the power cablewith the connection wires 
(low-voltage wires) of the indoor/outdoor unit. 
Power on the indoor unit after performing the airtight test and 
making a vacuum. 
For details of setting the address of the outdoor unit, see 
Outdoor unit address bits.
Trial run
Before operation, remove the six pieces of PE foaming which 
are used at the rear of the unit for protecting the condenser. Be 
careful not to damage the fin. Otherwise, the heat exchange 
performance may be affected.
Perform the trial run only after the outdoor unit has been 
powered on for over 12 hours.
