TEST RUNNING
Perform the electric safe check after completing installation:
1. Grounding work
After finishing grounding work, measure the grounding resistance by visual detection and
grounding resistance tester. Make sure the grounding resistance is less than 4 .
2. Electrical leakage check (performing during test running)
During test operation after finishing installation, the serviceman can use the electroprobe
and multimeter to perform the electrical leakage check. Turn off the unit immediately if
leakage happens. Check and find out the solution ways till the unit operate properly.

Apply a soapwater or a liquid neutral detergent
on the indoorunit connections andoutdoor unit
connections by asoft brush tocheck for leakage
of the connectingpoints of thepiping. If bubbles
come out, itindicates that thepipes have leakage.
2. Leak detector
Use the leak detector to check for leakage.
TEST RUNNING
3.Safety and leakage check
Perform test operationafter completing gas leak check at the flare nut connections and
electrical safety check.
Check that all tubing and wiring have been properly connected.
Check that the gas and liquid side service valves are fully open.
1. Connect thepower, press the ON/OFF button on the remote controller to turn the unit on.
2. Use theMODE button toselect COOL, HEAT,AUTO and FAN to check if all the functions
works well.

3. When theambient temperature istoo low(lower than 62 F), the unitcannot be controlled by
the remote controllerto run at cooling mode, manual operation can betaken. Manual
operation is usedonly when the remote controller is disable or maintenancenecessary.
4. The testoperation should last about 30 minutes.
The manual controlbutton is onthe bottom of the unit as shown in the picture. One press
of the manualcontrol button willlead to the forced AUTO operation. If pressthe button
twice within fiveseconds, the unitwill operate under forced COOL operation(see User
Manual for details).
When relocate the unit to another place,
perform evacuation using vacuum pump.
Make sure the refrigerant added into the air
conditioner is liquid form in any case.
(Not applicable to the units adopt freon R22 )
Open the valve stem until it hits against the
stopper. Do not try to open it further.
Securely tighten the valve stem cap with a
spanner or the like.

2.When Using the Vacuum Pump
(For method of using a manifold valve, refer
to its operation manual.)
1. Completely tighten the flare nuts, A, B, C, D,
connect the manifold valve charge hose to a
charge port of the low-pressure valve on the
gas pipe side.
2. Connect the charge hose connection to the
vacuum pump.
3. Fully open the handle Lo of the manifold valve.
4. Operate the vacuum pump to evacuate. After
starting evacuation, slightly loose theflare nut
of the Lo valve on the gas pipe side and
check that the air is entering(Operation noise
of the vacuum pump changes and a
compound meter indicates 0 instead of minus)
5. After the evacuation is complete, fully close
the handle Lo of the manifold valve and stop
the operation of the vacuum pump. Make
evacuation for 15 minutes or more and check
that the compound meter indicates
5
-76cmHg (-1x10 Pa).
6. Turn the stem of the packed valve B about
o
45 counterclockwise for 6~7 seconds after
the gas coming out, then tighten the flare nut
again. Make sure the pressure display in the
pressure indicator is a little higher than the
atmosphere pressure.
7. Remove the charge hose from the Low
pressure charge hose.
8. Fully open the packed valve stems B and A.
9. Securely tighten the cap of the packed valve.
