PREPARING THE COPPER TUBING (NOT INCLUDED)  
A copper tubing extension (not included) may need to be cut. If this is the case, it will also have to be deburred and  
flared as shown below:  
1. Cut the copper tube extension to the desired length  
with a tube cutter. It is highly recommended that 1  
foot is added to the requested length. After cutting,  
deburring may be necessary (see below diagram).  
Perform this with a tube reamer.  
2. Make a flare at the end of the copper tube with a  
flare tool.  
Make sure the inside surface and edges are smooth  
and the sides are uniform length.

CONNECTING COPPER TUBES  
To connect the copper tubes, follow the procedures below:  
1. Remove the flare nut stoppers from the inside unit.  
Determine the location of the copper tubing and  
where the bends will be. Gently bend the copper tub-  
ing, making sure to use big angles so no crimping  
will occur. Try to do this on the first try as repeated  
bending may break or crimp the tubing.  
2. Remove the plastic stoppers from the tubing.  
Connect the large and small copper tubing to the re-  
spective extension and rotate the flare nut with your  
finger until a smooth match is made. Make sure the  
copper extension has foam rubber (insulation) on it.

using a wrench. Be very careful not to strip the  
threads or flare nut. Repeat this process for the small  
and large tubing. When tightening the flare nut, use  
another wrench to securely hold the coupler from  
twisting and possibly damaging the tubing.  
5. Perform a leak test on all copper tube connections.  
To prevent heat loss and damage to walls from con-  
densation, the copper tube connections coming from  
the wall must be insulated. Do this by wrapping foam  
rubber or equivalent around the connection approxi-  
mately 8mm thick so no copper tubing is exposed.  
NOTES:  
• As with all wiring and hookups on this unit, make sure  
the AC plug on the indoor unit is unplugged.  
• Be very careful not to strip the threads or flare nut.  
• When insulating the connections, use foam rubber or  
equivalent.  
CONNECTING THE DRAIN HOSE  
To connect the drain hose, follow the procedures below:  
1. Connect the drain hose extension to the drain hose  
coming from the indoor unit by loosing the clamp on  
the extension using a phillips screwdriver, attaching  
the hoses together and then tightening the clamp.  
2. Run the drain hose, slanted downward, outside. If  
the drain pipe is exposed indoors, make sure it is  
thoroughly insulated so condensation does not ruin  
walls or furniture or come in contact with the AC con-  
nection or extension. Also, do not crease or form a  
trap in the tubing.

After running the wire, hose and tubing outside, tape them up as shown below to insulate.  
1. Tape the two copper tubes, drain hose (and the  
electrical wiring if local codes permit) together with  
the supplied tape. Make sure the electrical wiring  
does not come in direct contact with the copper  
tubing or drain hose. Approximately 1 foot outside  
the hole, let the drain hose out and separate from  
the copper tubing and wiring.  
2. Begin wrapping from the point the tubing comes out  
of the outdoor unit and continue to the hole in the  
wall. Leave no gaps or breaks and cover the entire  
length of the tubing. As you wrap, overlap the previ-  
ous turn by half the width of the tape.

AIR PURGING  
Indoor Unit  
Air and moisture remaining in the refrigerant system may create  
adverse conditions as indicated below:  
• pressure in the system rises  
• operating current rises  
• cooling efficiency drops  
• moisture in the refrigerant circuit may freeze and block capillary  
tubing  
• water may lead to corrosion of parts in the refrigerant system  
Outdoor Unit  
Therefore, the indoor unit and tubing between the indoor and  
outdoor unit must be leak tested and evacuated to remove any  
noncondesables and moisture from the system.  
AIR PURGING WITH VACUUM PUMP (TEST  
RUN)  
Confirm each tube (narrow and wide tubes) between the indoor  
and outdoor units has been properly connected and all wiring for  
the test run has been completed. Remove the valve caps from  
the wide and narrow service valves on the outdoor unit. Note that  
both narrow and wide tube service valves on the outdoor unit are  
kept closed at this stage (shipping position).

Leak Test  
1. With the service valves on the outdoor unit remaining closed,  
remove the threaded cover on the wide tube service port.  
(Save for reuse.)  
Charge Hose  
2. Attach a manifold valve (with pressure gauge) and dry nitro-  
gen gas cylinder to this service port with charge hoses.  
CAUTION:  
Be sure to use a manifold valve for air purging. If it is not avail-  
able, use a stop valve for this purpose. The “Hi” knob of the man-  
ifold valve must always be kept closed.  
Nitrogen Gas  
3. Pressurize the system to no more than 150 P.S.I.G. with dry  
nitrogen gas and close the cylinder valve when the gauge  
reading reaches 150 P.S.I.G. Next, test for leaks with liquid  
soap.  
Cylinder  
(Vertical  
Position)  
CAUTION:  
To avoid nitrogen entering the refrigerant system in a liquid state, the top of the nitrogen gas cylinder must be higher  
than its bottom when you pressurize the system. Usually, the cylinder is used in a vertical standing position.  
4. Do a leak test of all joints of the tubing (both indoor and outdoor) and both wide and narrow service valves. Bubbles  
indicate a leak. Be sure to wipe off the soap with a clean cloth.  
5. After the system is found to be free of leaks, relieve the nitrogen pressure by loosening the charge hose connector at  
the nitrogen cylinder. When the system pressure is reduced to normal, disconnect the hose from the cylinder.

INSTALLATION (CONTINUED)  
Evacuation  
Indoor Unit  
1. Attach the charge hose end described in the leak test  
area to a vacuum pump to evacuate the tubing and indoor  
unit. Confirm the “Lo” knob of the manifold valve is open.  
Then, run the vacuum pump. The operation time for evac-  
uation varies with the tubing length and capacity of the  
pump. The following table shows the amount of time for  
evacuation:

INSTALLATION (CONTINUED)  
TEST RUN  
Check that all tubing and wiring have been completed correctly. Check again that the wide and narrow tube service  
valves are fully opened. Turn on the power and run the system.  
Service Valve Construction  
• Valve Position Closed  
The valve systems of both the wide and narrow tubes are turned all the way in. The unit is shipped from the factory in  
this position and it is also used for Pump Down and Air Purging.  
• Valve Position Fully Open  
The valve stems of both the wide and narrow tubes are turned all the way out. This is normal operating and Test Run  
position.  
• Valve Position Half Open  
With the narrow tube valve stem is turned to the halfway-down position. This position is used for pressure measure-  
ment and gas charging.  
CAUTION:  
When opening or closing the service valve stem, be sure to use a hex wrench.  
PUMP DOWN  
Pump Down means collecting all refrigerant in the outdoor unit without loss in refrigerant gas.  
This is performed when the unit is to be relocated or the refrigerant circuit is serviced.  
CAUTION:  
Be sure to perform Pump Down procedure with the unit cooling mode.  
Pump Down Procedure  
1. Connect a low-pressure gauge manifold hose to the charge port on the wide tube service valve.  
2. Open the wide tube service valve halfway and purge the air from the manifold hose using the refrigerant gas.  
3. Close the narrow tube service valve (all the way in).  
4. Turn on the unit’s operating switch and start the cooling operation.  
5. When the low-pressure gauge reading becomes 1 to 0.5 kg/cm2 (14.2 to 7.1 psi), fully close the wide tube valve stem  
and then quickly turn off the unit. At that time, Pump Down has been completed and all refrigerant gas will have been  
collected in the outdoor unit.
