Test Run 

Before Test Run

A test run must be performed after the entire 
system has been completely installed. Confirm 
the following points before performing the test: 
  a) The indoor and outdoor units are properly 

installed.

b) Piping and wiring are properly connected.
c) Ensure that there are no obstacles near the 

inlet and outlet of the unit that might cause 
poor performance or product malfunction.   

d) The refrigeration system does not leak. 
e) The drainage system is unimpeded and 

draining to a safe location. 

f) The heating insulation is properly installed.
g) The grounding wires are properly connected.
h) The length of the piping and the added 

refrigerant stow capacity have been recorded. 

i) The power voltage is the correct voltage for 

the system. 

 CAUTION

Failure to perform the test run may result in unit 
damage, property damage or personal injury. 

Test Run Instructions

1. Open both the liquid and gas stop valves. 
2. Turn on the main power switch and allow the 

unit to warm up.  

3. Set the air conditioner to COOL mode.
4. For the Indoor Unit

a. Ensure the remote control and its buttons 

work properly.  

b. Ensure the louvers move properly and can 

be changed using the remote control. 

c. Double check to see if the room 

temperature is being registered correctly. 

d. Ensure the indicators on the remote control 

and the display panel on the indoor unit 
work properly. 

e. Ensure the manual buttons on the indoor 

unit works properly. 

f. Check to see that the drainage system is 

unimpeded and draining smoothly. 

g. Ensure there is no vibration or abnormal 

noise during operation. 

5. For the Outdoor Unit

a. Check to see if the refrigeration system is 

leaking. 

b. Make sure there is no vibration or 

abnormal noise during operation. 

c. Ensure the wind, noise, and water 

generated by the unit do not disturb your 
neighbors or pose a safety hazard.

NOTE: 

If the unit malfunctions or does not 

operate according to your expectations, please 
refer to the Troubleshooting section of the 
Owner’s Manual before calling customer service.
