10.5.2. Before installation work
This product is using new refrigeration (R410A). The basic way of installation work is the same as usual, but water and impurities should be controlled more strictly than before due to characteristic of refrigerating machine oil. Therefore, selection of materials to use and processing, storing and brazing need appropriate construction and control. 1. Tools and materials There are tools and materials for both new refrigeration and usual refrigeration you can use together and for either two of them you can use. Use the below for new refrigeration. Vacuum pump (with back flow preventor system) Gas leakage detection warning decive Gauge manifold Charge hose 2. Installation work a. Brazing work Brazing work needs replacing air inside pipe with nitrogen gas in order to prevent oxidization scale from occurring. This is called nitrogen replacement, and one of very important work in brazing refrigerant piping. (Oxidation preventive is not possible to use)

If there are obstructions near the outdoor unit and the wind direction is not constant, install an optional air guider. 9. Do not allow any obstacles near the outdoor unit which will interfere with air flow around the air intake and air outlet. 10. If installing in a location which is prone to snowfall, place the installation base as high as possible, and be sure to install a roof or enclosure which does not allow snow to accumulate. 11. Avoid installing the unit in places where petroleum products (such as machine oil), salinity, sulphurous, gases or high-frequency noise are present.
12. Be sure to leave enough space around the outdoor unit to maintain proper performance and to allow access for routine maintenance. Allow enough space from any obstacles as shown in Fig. 1.2 below in order to prevent short-circuits from occurring. (If installing more than one outdoor unit, make the necessary space available as outlined in 13.) However, there should be at least 1 meter of free space above the unit. The height of any obstacles at the air intake and outlet sides should not be greater than the height of the outdoor unit.
13. If installing more than one outdoor unit, allow enough space around each unit as shown below.
Maintain sufficient space above the unit. Values inside brackets indicate distances when installing the 4HP - 6HP. The distance given above are the minimum distance required in order to maintain proper performance. Allow as much space as possible in order to get the best performance from the units.
10.5.5. Transporting and installing the outdoor unit
Transporting 1. The outdoor unit should be transported in its original packaging as close to the installation location as possible. 2. If suspending the outdoor unit, use a rope or belt, and use cloth or wood as padding in order to avoid damaging the unit. Installation 1. Read the Selecting the outdoor unit installation location section thoroughly before installing the outdoor unit. 2. If installing the unit to a concrete base or other solid base, use M10 or W3/8 bolts and nuts to secure the unit, and ensure that the unit is fully upright and level. (The anchor bolt positions are shown in the diagram at the right side.) In particular, install the unit at a distance from the neighbouring building which conforms to regulations specified by local noise emission regulation standards. 3. Do not install the outdoor unit to the buildings roof. 4. If there is a possibility that vibration may be transmitted to the rooms of the building, place rubber insulation between the unit and the installation surface. 5. Drain water will be discharged from the outdoor unit when operating the system in heating or defrosting modes. Select an installation location which will allow the water to drain away properly, or provide a drainage channel so that the water can drain away. (If this is not done, the drain water may freeze during winter, or the water may spill down to areas underneath the installation location.)

If installing with the remote control cable exposed 1. Secure the remote controller base plate to the wall with two accessory 4 mm screws. 2. The feeding-out direction for the remote control cable can be either up or to the left or right. (Refer to the illustration above.) After determining the feeding-out direction, use nippers to make a notch in the cover. 3. Route the remote control cable as shown in the illustration above. Pull the cord firmly around the outside of the base plate at this time.

10.6.4. Settings

Control using two remote controllers
Up to two remote controllers can be installed for a single indoor unit, and either remote controller can be used to operate the indoor unit. The indoor unit can be operated with the last switch pressed having priority. 1. Decide which is to be the master and which is to be the slave remote controller. The master or slave states of the remote controller are set automatically. The MASTER/SLAVE setting switch can also be use to make the setting manually, however if a manual setting is made, that manual setting has priority. Be sure to turn off the main power before making a manual setting. 2. Connect the remote controllers. Connect both remote controller to terminals (A) and (B) on the indoor unit terminal block (non-polar).

10.7.2. Points and notes regarding wireless remote controller setting-up location
The wireless remote controller can be used to operate indoor units at a maximum range of 8 metres from directly facing infront of the indoor unit. If the remote controller is at an angle to the receptor unit, the operation range may become shortened. The accessory receptor unit must be attached to the veneer panel. The receptor unit for the wireless remote controller should be in a place where it will not be affected by direct light from fluorescent lights. (Refer to the illustration below.) (If using an inverter-type fluorescent light, keep the receptor unit at least 1m away from the light, otherwise remote control operation may not work properly.)
If installing in a place where a power supply is generating electromagnetic noise, take measures such as installing a noise filter. Install at least 3m away from any noise sources, and shield the electric cables using an iron conduit pipe. Install at least 1m away from equipment such as TVs and radios. (Otherwise picture distortion or static may occur.)
Wireless remote control installation procedure
Installing the wireless remote controller to a wall (for remote control storage).
If using a single remote controller to operate several air conditioners, address setting will be required. (Refer to later in this manual.) For twin and triple types, install to the main unit only. (Accordingly, the installation and wiring operations described later in this manual are for the main unit only.)

Inserting the batteries

Remove the battery compartment cover of the wireless remote controller, and then insert the two accessory R03 size batteries. (Be sure not to make a mistake with the polarities.) NOTE The accessory batteries are to be used when checking operation. They should be replaced with new batteries as soon as possible. (Be sure not to make a mistake with the polarities.)

Fig. 6 Electric gas leak detector for HFC refrigerant
8. Electronic scale for refrigerant charging Because of the high pressure and fast vaporizing speed of R410A, the refrigerant cannot be held in a liquid phase inside the charging cylinder when charging is done using the charging cylinder method, causing bubbles to form in the measurement scale glass and making it difficult to see the reading. (Naturally, the conventional R22 charging cylinder cannot be used because of the differences in the pressure resistance, scale gradation, connecting port size, etc.) The electronic scale has been strengthened by using a structure in which the weight detector for the refrigerant cylinder is held by four supports. It is also equipped with two connection ports, one for R22 (7/16 UNF, 20 threads) and one for R410A (1/2 UNF, 20 threads), so it can also be used for conventional refrigerant charging. There are two types of electronic scales, one for 10-kg cylinders and one for 20-kg cylinders. (The 10-kg cylinder is recommended.) Refrigerant charging is done manually by opening and closing the valve. 9. Refrigerant cylinders The R410A cylinders are labeled with the refrigerant name, and the coating color of the cylinder protector is pink, which is the color stipulated by ARI of the U.S. Cylinders equipped with a siphon tube are available to allow the cylinder to stand upright for liquid refrigerant charging.

11.3. Refrigerant piping work

11.3.1. Piping materials

It is recommended that you use copper and copper alloy jointless pipes with a maximum oil adherence of 40 mg/10m. Do not use pipes that are crushed, deformed, or discolored (especially the inside surface). If these inferior pipes are used, impurities may clog the expansion valves or capillaries. Because the pressure of ACs using R410A is higher than those using R22, it is essential that you select materials that are appropriate for these standards. The thickness of the copper tubing used for R410A is shown in Table 10. Please be aware that tubing with a thickness of only 0.7 mm is also available on the market, but this should never be used.

11.3.2. Processing and connecting piping materials
When working with refrigerant piping, the following points must be carefully observed: no moisture or dust must be allowed to enter the piping, and there must be no refrigerant leaks. 1. Procedure and precautions for flaring work a. Cut the pipe Use a pipe cutter, and cut slowly so the pipe will not be deformed. b. Remove burrs and clean shavings from the cut surface If the shape of the pipe end is poor after removing burrs, or if shavings adhere to the flared area, it may lead to refrigerant leaks. To prevent this, turn the cut surface downward and remove burrs, then clean the surface, carefully. c. Insert the flare nut (be sure to use the same nut that is used on the AC unit) d. Flaring Check the clamp bar and the cleanliness of the copper pipe. Be sure to use the clamp bar to do the flaring with accuracy. Use either an R410A flaring tool, or a conventional flaring tool. Flaring tools come in different sizes, so be sure to check the size before using. When using a conventional flaring tool, use the copper pipe gauge for clearance adjustment, etc., to ensure the correct A dimension (see Fig. 10)
