Procedure for Selecting the Location

Ⴠ

Ⴠ

Choose a place solid enough to bear the weight and vibration of the unit,where the operation noise will not be amplified.

Choose a location where the hot air discharged from the unit or the operation noise,will not cause a nuisance to the neighbors of the user.

Ⴠ

Ⴠ

Ⴠ

Ⴠ

Avoid places near a bedroom and the like,so that the operation noise will cause no trouble.

There must be sufficient space for carrying the unit into and out of the site.

There must be sufficient space for air passage and no obstructions aroud the air inlet and air outlet.

The site must be free from the possibility of flammable gas leakage in a nearby place.

Locate the unit so that the noise and discharged hot air will not annoy the neighbors.

Ⴠ Install units,power cords and inter-unit cables at least 10ft away from televison and radio sets,This is prevent interference to images and sounds.(Noise may be heard even if they are more than 10ft away depending on radio wave conditions.)

Ⴠ

Ⴠ

In coastal areas or other places with salty atmosphere of sulfate gas,corrosion may shorten the life of the air condition.

Since drain flows out of the outdoor unit,do not place under the unit anything which must be kept away from moisture.

Fitting of the Mounting Plate and Positioning of the wall Hole

When the mounting plate is first fixed

1. Carry out, based on the wall studs or lintels, a proper leveling for the plate to be fixed against the wall, then temporarily fasten the plate with one nail.

2. Ensure the proper level of the plate, by hanging a thread with a weight from the central top of the plate, then fasten the plate.

3. Find the wall hole location A using a measuring tape

Left-rear piping ]

ƽ In case of left side piping, cut away, with a nipper, the lid for left piping.

ƽ In case of left-rear piping, bend the pipes according to the piping direction to the mark of hole for left-rear piping which is marked on insulation materials.

1. Insert the drain hose into the carity of heat insulation materials of indoor unit.

2. Insert the indoor/outdoor electric cable from backside of indoor unit, and pull it out on the front side, then connect them.

3. Coat the flaring seal face with refrigerant oil and connect pipes.

Cover the tubing connection with insulation materials closely, and with adhesive tape.

[ Other direction piping ]

ƽ Cut away, with a nipper, the lid for piping according to the piping direction and then bend the pipe according to theposition of wall hole. When bending, be careful not to crush pipes.

ƽ Make sure that the wires connecting the indoor and outdoor units are not covered by the refrigeration piping insulation and are long enough to connect to the terminal block on the indoor unit.

Fixing the indoor unit body

ƽ Hang the unit body onto the upper notches of the mounting plate. Move the body from side to side to verify its secure fixing.

ƽ In order to fix the body onto the mounting plate,hold up the body from the underside and then put it down perpendicularly.

Unloading of indoor unit body

Connection

ƽ Loosen the screws on terminal block and insert the wires fully into terminal block, then tighten the screws.

ƽ If wiring is not correct, the unit will not operate properly and it could cause a defect in the unit.

ƽ

Fix the cable with a clamp.

Attaching Drain-Elbow ƽ If the drain-elbow is used, please attach as shown in figure.

(Note: Only for heat pump unit.)

Purging Method:To use vacuum pump

1.

Detach the service port’s cap of 3-way valve, and the valve cap for 2-way valve and 3-way valve. Connect the service port to the low side of the gauge manifold and connect the vacuum pump to the center port of the manifold.

2.

Open the handle on the low side of the gauge manifold and operate vacuum pump.

3.

Vacuum the tubing for at least 15 minutes. The vacuum level on the low side gauge should be 29.9 in of Hg, 76 cm of Hg, 0.1 MPa. when vacuuming is complete, close the valve on the manifold and turn off the vacuum pump. The vacuum level should hold for 1-2 minutes. If the vacuum level does not hold, check the flared connections and repeat this step.

4.

Open the 2-way valve 1/4 turn. After 5-6 seconds, close the valve and inspect for leaks with a leak detector or soap solution.

5.

No gas leakage? Go to step 6.

In case of a leak, try tightening the flare connections to fix the leak. If the leak stops, go to step 6. If the leak continues, check the flare connections and repair as needed, then go back to step 3. then proceed step 6. If leak continues, remove the refrigerant used for the leakage check and flare tubes again. Repeat vacuum and leak and if no leakage, proceed to step 6.

6.

Detach the charge hose valve completely.

from the service port, open 2-way valve and 3-way

7.

To prevent the gas leakage, replace the service port and valve caps.

8.

After attaching the caps, check for leakage around the caps.

CAUTION

ƽ

If the refrigerant of the air conditioner leaks, it is necessary to discharge all the refrigerant. Repair the leak, vacuum the unit then charge the liquid refrigerant ƽ into air conditioner according to the amount marked on the name plate.

Please do not let other cooling medium, except specified one (R410A), or air enter into the cooling circulation system. This could cause high pressure and could cause a leak and lead to personal injuries.

Power Source Installation ƽ ƽ ƽ

The power source must be exclusively used for air conditioner.

In the case of installing an air conditioner in a moist place, please install an earth leakage breaker.(GFCI)

For installation in other places, use an HVACR circuit breaker of time delay fuse.

On Drainage ƽ Please install the drain hose and ensure downward flow.

ƽ Please don’t do the drainage as shown below.
