INSTALLATION

1. Determine the type of wall (sheetrock, concrete, etc.) and make sure it is strong enough to hold indoor unit. Select an approximate position for the unit, taking the required distances away from walls/AC outlet into consideration.

INDOOR UNIT

• Do not install the unit in an area with direct sunlight, near

heat sources (radiator, etc.), or an area where leakage of flammable gas may be expected.

• Select a position in the room, high on the wall, where the whole room can be uniformly cooled.

• Select a location that can hold the weight of the unit and where the copper tubing, drain hose and Indoor to Outdoor Wire have the shortest distance to the Outdoor unit.

• Make sure the Indoor unit is installed at least 10cm (3.95in) away from the top and left side wall and at least 30cm (11.8in) from AC outlet and right side wall.

OUTDOOR UNIT

• Do not install the unit in an area near heat sources,

exhaust fans, or an area where leakage of flammable gas may be expected.

• Do not install the unit in a humid, damp or uneven location.

• Select a location that is well ventilated .

• Leave enough room around the unit for air intake, exhaust

and possible maintenance.

2. Determine if the hole is to be made at the left or right hole location.

3. Using drill with hole-cutting attachment or equivalent, cut a hole 70mm (2.75") in diameter. The hole should be made at a slight downward slant to the outdoor side. Measure the thickness from the inside to outside edges and cut a PVC pipe at a slight angle 1/4" shorter than the thickness of the wall and insert pipe in wall.

4. For sheetrock, wooden or similar wall, measure down from the ceiling using a level or tape measure and attach the wall bracket to the wall using 4 screws. If you are not able to line up the holes with the beams, use toggle bolts. Make sure the wall bracket is even and flush against the wall.

Indoor Outdoor

Cut at slight angle

CAUTION

• Before making hole, make sure there are no studs, pipes, electrical wiring or conduit directly behind the area to be cut.

For Concrete, or similar type wall, make holes into the wall and insert concrete nails instead of screws.

INST ALLING THE INSTALLATION PLATE

To install the wall bracket, follow the procedures below. One hole is required for the tubing and may be either on the left or right side.

SELECTING A SITE:

• TAS-18/24

• TAS-15

• TAS-12

CAUTION:

• When using the tube reamer, hold the tube downward and make sure no copper scraps fall into the tubing.

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.

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.

BEFORE AFTER

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:

Flare tool

Flare nut

Connection

pipe

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 tubing, 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 respective 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.

Flare Nutcoupler

CONNECTING THE COPPER TUBES

To connect the copper tubes, follow the procedures below:

NOTE:

When removing the flare nut stopper from the inside unit, confirm “Ping”, sounds because the mixed gas is charged in the inside unit,

3. Once a smooth match is made, tighten the flare nut 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.

4. Remove the flare nut stoppers from the outdoor unit’s valves. Connect the larger copper tubing to the larger valve on the outdoor unit. Connect the smaller copper tubing to the smaller valve on the outdoor unit.

5. Perform a leak test on all copper tube connections. To prevent heat loss and damage to walls from condensation, the copper tube connections coming from the wall must be insulated. Do this by wrapping foam rubber or equivalent around the connection approximately 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.

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 connection or extension. Also, do not crease or form a trap in the tubing.

AIR PURGING

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

Therefore, the indoor unit and tubing between the indoor and outdoor unit must

AIR PURGING WITH VACUUM PUMP (TEST RUN)

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

(Save for reuse.)

CA UTION:

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 manifold valve must always be kept closed.

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.

CA UTION:

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.

be leak tested and evacuated to remove any noncondesables and moisture from the system.

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.

1. With the service valves on the outdoor unit remaining closed, remove the threaded cover on the wide tube service port.

2. Attach a manifold valve (with pressure gauge) and dry nitro gen gas cylinder to this service port with charge hoses.

Evacuation

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 evacuation varies with the tubing length and capacity of the pump. The following table shows the amount of time for evacuation:

2. When the desired vacuum is reached, close the Lo knob

of the manifold valve and stop the vacuum pump.

Finishing the job

1. With a hex wrench, turn the narrow tube service valve

stem counter-clockwise to fully open the valve.

2. Turn the wide tube service valve stem counter-clockwise

to fully open the valve.

CA UTION:

To avoid gas from leaking when removing the charge hose, make sure the wide tube service valve is fully open and turned all the way out.

3. Loosen the charge hose connected to the wide tube ser-

vice port slightly to release the pressure, then remove the hose.

4. Replace the threaded cover on the wide tube service port

and fasten it securely. This process is very important to prevent gas from leaking from the system.

5. Replace the valve caps at both wide and narrow service

valves and fasten them securely.

This completes air purging with a vacuum pump. The air conditioner is now ready to test run..

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 measurement 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.
