b. Prevention measure for refrigerant piping Prevention measure for refrigerant piping is very important work to prevent water-dust-rubbish from getting in. All piping terminals needs sealing such as shown below.
Place Outside Inside Period of work More than 1 month Less than 1 month Not specified Method of seal Pinch Pinch or taping
How to pinch Close terminal part of piping with pliers and seal the gap with brazing.
How to tape Seal terminal part of piping with vinyl tape.
3. Vacuum pumping The purpose of vacuum pumping work is to remove and dry air inside the piping or nitrogen at air tightness test. Perform the work carefully.
Caution Use the vacuum pump with the backflow prevention mechanism to prevent backflow of oil.

Vacuuming time

60 minutes or more
Vacuum pump capacity 60 l/min or more
4. Refrigerant filling Refrigerant filling must be done in the state of liquid refrigerant. If this is done in gas refrigerant, the balance of refrigerant composition will collapse and damage the operation.
For the use of a gas cylinder without siphon inside, turn it upside down and use it. (We recommend manifold with sight glass.)

Caution Caution

Do not use a CHARGE CYLINDER. As a rule, please collect all existing refrigerants in the system outside the system when the refrigerant leakage occurs by the system. After that, please fill new refrigerant of a regulated amount again.
DRY VACUUMING If vacuum pump possible vacuuming until less than -100.7kpa. 1. Running vacuum pump at both liquid and gas side for more than 1 hour and vacuuming until -100.7kpa. 2. After that keep the pressure -100.7kpa for 1 hour and confirm the vacuum gauge value not increasing. 3. If vacuum gauge value is increase, there is possibility of water inside the unit or there is any leakage.
10.5.3. Regarding handling
Handling the unit by hold the handle at compressor side and hold the basepan bottom at fan side.
10.5.4. Selecting the outdoor unit installation locations
Select location which satisfies the following condition, and then confirm with the customer that such a place is satisfactory before installing the outdoor unit.
1. 2. 3. 4. 5. 6. 7. 8. There should be sufficient ventilation. The outdoor unit should be sheltered as much as possible from rain and direct sunlight, and the air should be able to move around so that hot and cold air do not build up. There should not be animals or plants near the air outlet which could be adversely affected by hot or cold air coming out from the unit. The outlet air and operating noise should not be a nuisance to other occupants nearby. The location should be able to withstand the full weight and vibration of the outdoor unit, and it should also be level and safe for the unit to be installed. The intake and outlet should not be covered. There should not be danger of flammable gas or corrosive gas leaks. There should be as little back-ventilation (air blowing directly onto the fan) as possible. (If strong wind blows directly onto the fan, it may cause problems with normal operation.) If you know which direction the prevailing wind comes from during the operating season, set the outdoor unit at a right-angle to this wind direction, or so that air outlet faces toward a wall or fence.

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.)

4. After piping connection has been completed, make sure that the joint areas of the indoor and outdoor units are free from gas leakage by the use of nitrogen, etc. 5. Air purge within connection piping shall be carried out by evacuation. 6. Close the tube joining area with putty heat insulator (local supply) without any gap as shown in below figure. (To prevent insects or small animal entering)

10.5.7. Heat insulation

Use a material with good heat-resistant properties as the Caution heat insulation for the pipes. Be sure to insulate both the gas-side and liquid-side pipes. If the pipes are not adequately insulated, condensation or water leakages may occur. Liquid-side pipes Gas-side pipes Material that can withstand 120C or higher
10.5.8. Charging with refrigerant
At the time of shipment from the factory, this unit is charged with enough refrigerant for an equivalent pipe length of 30m. If the equivalent pipe length used will be 30m or less, no additional charging will be necessary. If the equivalent pipe length will be between 30 and 50m, charge with additional refrigerant according to the equivalent length given in the table below. For standard type
Additional charging amount 0.05 kg/m Equivalent length 50m
Pump down operation Operate the pump down according to the following procedures.
Procedure 1. Confirm the valve on the liquid side and the gas side is surely open. 2. Press the PUMP DOWN switch on outdoor printed board for 1 second or more. 3. Shut the valve on the liquid side surely. Notes Perform the cooling operation for five minutes or more. When the valve is shut halfway, the compressor is occasionally damaged.
10.5.9. Electrical wiring
Warning The units must be connected to the supply cables for fixed wiring by qualified technician. Feed the power source to the unit via a distribution switch board designed for this purpose, the switch should disconnected all poles with a contact separation of at least 3mm. When the supply cable is damaged, it must be replaced by qualified technician. Be sure to install a current leakage breaker, main switch and fuse to the main power supply, otherwise electric shocks may result. Be sure to connect the unit to secure earth connection. If the earthing work is not carried out properly, electric shocks may result. Wiring shall be connected securely by using specified cables and fix them securely so that external force of the cables may not transfer to the terminal connection section. Imperfect connection and fixing leads to fire, etc.

Warning

Connect the power supply wiring and indoor/outdoor unit connection wiring according to the electrical circuit diagram instructions. Clamp the wires securely to the terminal connections using cord clamps so that no undue force is placed on the wires. Once all wiring work has been completed, tie the wires and cords together with the binding strap so that they do not touch other parts such as the compressor and pipes.

Remove the remote controller lower case. (Insert a flat-tipped screw driver or similar 2 to 3 mm into one of the gaps at the bottom of the case, and then twist the screw driver to open. [Refer to the illustration below.]) Be careful not to damage the lower case.
Secure the lower case to the wall or outlet box. (Refer to the illustration at right for the embedded and exposed positions for remote control cable.) NOTE Be sure to use only the accessory screws. Do not bend the lower case when tightening the screws. (If the screws are overtightened, damage may result.) Do not remove the protective tape which is affixed to the upper case circuit board. If installing the remote controller with the remote control cable exposed, use pliers to cut a notch into the upper case. (The feeding-out direction can be either up or to the left or right)
Strip the end of the remote control cable which is to be connected to the remote controller. (Refer to the illustration below)
Route the remote control cable inside the lower case in accordance with the intended feeding- out direction. (Refer to the illustration below.) Securely connect connector CN1. (If it is not connected the remote controller will not operate.)
NOTE After connecting the connector, do not suspend the upper case by its own weight, otherwise the connector cord may break.
If controlling using two remote controllers, refer to Control using two remote controller-s in 4 Settings. Secure the upper case to the lower case. (Hook the upper tab of the upper case into the lower case, and then push the upper case until it snaps shut onto the lower case tab, while being careful not to clamp the remote control cable and the connector cord.)
If remote control cable is embedded 1. Embed an outlet box (JIS C 8336) into the wall, and then secure the remote controller base plate to the outlet box with the two accessory M4 screws. Make sure that the base plate is flat against the wall at this time, with no bending (looseness) 2. Pass the remote control cable into the box and then install the remote controller.
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.

6. Vacuum pump adaptor When using a vacuum pump for R410A, it is necessary to install an electromagnetic valve to prevent the vacuum pump oil from flowing back into the charging hose. The vacuum pump adaptor is installed for that purpose. If the vacuum pump oil (mineral oil) becomes mixed with R410A, it will damage the unit.
Fig. 5 Vacuum pump adaptor
7. Electric gas leak detector for HFC refrigerant The leak detector and halide torch that were used with CFC and HCFC cannot be used with R410A (because there is no chlorine in the refrigerant). The present R134a leak detector can be used, but the detection sensitivity will be lower (setting the sensitivity for R134a at 1, the level for R410A will drop to 0.6). For detecting small amounts of gas leakage, use the electric gas leak detector for HFC refrigerant. (Detection sensitivity with R410A is about 23 g/year).
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.
Fig. 7 Electronic scale for refrigerant charging
Fig. 8 Refrigerant cylinders
10. Charging orifice and packing for refrigerant cylinders The charging orifice must match the size of the charging hose fitting (1/2 UNF, 20 threads). The packing must also be made of an HFC-resistant material.
