side. 2. Always use wall hole conduit when drilling metal grid, metal plate or the like. 2.4 FLARING WORK AND CONNECTION OF PIPING The main cause for gas leakage is due to defects in flaring work. Carry out correct flaring work using the following procedure. 2.4.1 Flaring work 2.4.1.1 Cut the pipes and the cable. Use the piping kit accessory (if applicable) or the pipes purchased locally. Measure the distance between the indoor and the outdoor unit. Cut the pipes a little longer than measured distance. Cut the cable 1.5m longer than the pipe length.

2.4.1.4 Flaring work

Carry out flaring work using flaring tool as shown below.

"A" (mm) Max. Min. 1.3 0.7 1.6 1.0 1.8 1.0 2.4 1.8

Hold copper pipe firmly in a die according to the dimension shown in the table above. 2.4.1.5 Check Compare the flared work with the adjacent diagram. If flare is found to be defective, cut off the flared section and do flaring work again.

2.4.1.2 Burrs removal Completely remove all burrs from the cut cross section of pipe/tube. Place the end of the copper tube/pipe in a downward direction as you remove burrs in order to avoid dropping burrs into the tubing.

2.4.2 Connection of pipes - Indoor Prepare the indoor unit's piping and drain hose for installation through the wall. Remove the tubing retainer (see illustration right) and pull the tubing and drain hose away from chassis (If required). For some models this is not needed. Replace the tubing retainer in its original position.

2.4.1.3 Putting flare nut on Remove flare nuts attached to indoor and outdoor unit, then put them on pipe/tube having completed burr removal. (Note: It is not possible to put them on after flaring work.)

CAUTION When installing the indoor unit, be sure to remove the relevant sections where required (see

This will allow piping and cable routing to be completed without damaging the unit. 2.4.2.1 For rear right piping Note: When viewed from the front of the indoor unit. 2.4.2.1.6 Locating the indoor unit Hook the indoor unit onto the upper portion of the installation plate (Engage the hooks of the installation plate into the openings at the rear top of the indoor unit). Ensure that the hooks are properly seated on the installation plate by moving 2.4.2.1.1 Route the indoor tubing and the drain hose in the direction of rear right. 2.4.2.1.2 Insert the connecting cable into the indoor unit from the outdoor unit through the piping hole. Do not connect the cable to the indoor unit. Make a small loop with the cable for easy connection later. 2.4.2.1.3 Tape the tubing, drain hose and the connecting cable. Be sure that the drain hose is located at the lowest side of the bundle. Locating at the upper side can cause drain pan to overflow inside the unit. 2.4.2.1.7 Connecting the piping to the indoor unit and the drain hose to drain pipe. Align the centre of the piping and sufficiently tighten the flare nut by hand. the indoor unit left and right. Press the lower left and right sides of the unit against the installation plate until the hooks engage into their slots (clicking sound).

Tighten the flare nut with a wrench, in accordance with the following table. Note: If the drain hose is routed inside the room, insulate the hose with an insulation material so that dripping from "sweating" (condensation) will not damage furniture or floors. *Foamed polyethylene or equivalent is recommended. 2.4.2.1.4 Insert the piping, drain hose and the connecting cable into the piping hole. 2.4.2.1.5 Set the piping and the drain hose to the back of the chassis with the tubing holder.

2.7 AIR PURGING 2.7.1 Air purging Air and moisture remaining in the refrigerant system have undesirable effects as indicated below. Pressure in the system rises. Operating current rises. Cooling (or heating if applicable) efficiency drops. Moisture in the refrigerant circuit may freeze and block capillary tubing. Water may lead to corrosion of parts in the refrigeration system. Therefore, the indoor unit and tubing between the indoor and outdoor unit must be leak tested and evacuated to remove any non-condensable substance and moisture from the system. 2.7.2 Air purging with vacuum pump 2.7.2.1 Preparation Check that each tube (both liquid and gas side tubes) between the indoor and outdoor units have been properly connected and all wiring for the test run has been completed. Remove the service valve caps from both the gas and the liquid side on the outdoor unit. Note that both the liquid and the gas side service valves on the outdoor unit are kept closed at this stage. 2.7.2.2 Leak test Connect the manifold set (with pressure gauges) and dry nitrogen gas cylinder to this service port with charge hoses. CAUTION Be sure to use a manifold set for air purging. If it is not available, use a stop valve for this purpose. The "Hi" knob of the manifold valve must always be kept closed. Pressurizes the system to no more than 1MPa (Approx. 145psi) with dry nitrogen gas and close the cylinder valve when the gauge reading reaches 1MPa (Approx. 145psi). Next, test for leaks with liquid soap. CAUTION

Nitr ogen g as cyli nder ( in vert ic al st a nding p osition )

To avoid nitrogen entering the refrigerant system in a liquid state, the top of the cylinder must be higher than its bottom then you pressurise the system. Usually, the cylinder is used in a vertical standing position. Do a leak test of all joints of the tubing (both indoor and outdoor) and both gas and liquid side service valves. Bubbles indicate a leak. Be sure to wipe off the soap with a clean cloth. 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. Gas leak check 1. Apply a soap water or a liquid neutral detergent

2.7.2.3 Evacuation Connect the charge hose end described in the preceding steps to the vacuum pump to evacuate the tubing and indoor unit. Confirm the "LO" knob of the manifold set is open. Then run the vacuum pump. The operation time for evacuation varies with tubing length and capacity of the pump. The following table is a guide for evacuation times. Times are dependent on tubing length and pump capacity. Pipe Length (L) <5m 5~10m Air Purge Method Use Vacuum Pump Use Vacuum Pump Timer required (min) 25 30

2.7.2.4 Finishing the job With a service valve wrench, turn the valve stem of liquid side valve counter-clockwise to fully open the valve. Turn the valve stem of gas side valve counter-clockwise to fully open the valve. Loosen the charge hose connected to the gas side service port slightly to release the pressure, then remove the hose. Replace the valve cap on the gas side service port and fasten the cap securely. This process is very important to prevent leakage from the system. Replace the valve caps at both gas and liquid side service valves and fasten them tightly. This completes air purging with a vacuum pump. The air conditioner is now ready to test run.

When the desired vacuum is reached, close the "LO" knob of the manifold set and stop the vacuum pump.
