Preparation Outdoor unit location requirements Installation Guide at the seashore Examine the area where the outdoor unit could be located. Consider the following: Make sure to follow below guides when installing at the seashore. •• What location will meet minimum clearances and provide optimal product performance? 1 •• Is there an existing level and hard foundation, such as a concrete pad, that will support the unit weight and produce minimal vibration? Installation on uneven ground may result in abnormal vibrations, noise, or problems with the unit. Do not install the product in a place where it is directly exposed to sea water and sea breeze. ‐‐ Make sure to install the product behind a structure (such as building) that can block see breeze. ‐‐ Even when it is inevitable to install the product in seashore, make sure that product is not directly exposed to sea breeze by installing a protection wall. •• Does the unit need to be mounted on the wall? 2 •• Where are the dedicated circuit breaker and disconnect switch located? How will you connect them to the unit? Consider that the salinity particles clinging to the external panels should be sufficiently washed out. 3 Because the residual water at the bottom of the outdoor unit significantly promotes corrosion, make sure that the slope does not disturb drainage. •• How will you route the piping bundle from the indoor unit? Is the location as close as possible to where the indoor unit will be installed, to minimize the length of piping and cables? ‐‐ Keep the floor level so that rain does not accumulate. ‐‐ Be careful not to block the drain hole due to foreign substance. •• Will the unit be sheltered from the wind? In a high‑wind area, you may need to build a protective fence around the unit. 4 •• Where will the condensate drain? When product is installed in seashore, periodically clean it with water to remove attached salinity. 5 Make sure to install the product in a place that provides smooth water drainage. Especially, ensure that the base part has good drainage. 6 If the product is damaged during the installation or maintenance, make sure to repair it. 7 Check the condition of the product periodically. WARNING •• The drain location must allow condensate to drain properly and prevent ice from forming on the unit in winter. If a block of ice falls from the unit, it may result in death, serious injury, or property damage. Improper or inadequate draining may result in water overflowing and property damage. Installation CAUTION •• Do not connect the drain hose to existing waste pipes as odors may arise. Installation on an exterior wall If the outdoor unit must be installed on an exterior wall, you will need an L‑bracket to support the unit. This bracket is not included with the unit. WARNING •• The wall must be capable of supporting the weight of both the L‑bracket and the outdoor unit. If the unit falls, it may result in crushing, electric shock, fire, or explosion that could cause death, severe personal injury, or property damage. 6 English 8 ‐‐ Check the installation site every 3 months and perform anti-corrosion treatment such as R-Pro supplied by SAMSUNG (Code : MOK-220SA) or commercial water repellent grease and wax, etc., based on the product condition. ‐‐ When the product is to be shut down for a long period of time, such as off-peak hours, take appropriate measures like covering the product.

If the screw locations do not align with the studs, use wall anchors. Step 2.2 Drilling the wall penetration 1 Determine the position of the hole through which the piping bundle (consisting of power and communication cables, refrigerant pipes, and the drain hose) will pass. Consider the following: ‐‐ The hole inner diameter must be 65 mm. ‐‐ The recommended hole location is behind the unit so that the hole and the piping bundle will not be visible in the room. The minimum distances between the hole and the mounting bracket are: CAUTION •• The recommended best practice is to attach the mounting bracket directly to the studs in the wall. If you did not find a suitable location with studs (in Step 1.2 on page 5), or if the wall is concrete, you must use wall anchors of a suitable type and weight capacity, and install them according to the manufacturer’s instructions. Failure to do so may cause the material surrounding the joints to crumble over time and the screws to be loosened and stripped. This may result in the unit falling from the wall, which could cause physical injury or equipment damage. 2 Using a level, make sure that the mounting bracket is level, then mark the location of the screw holes on the wall. 3 If using wall anchors, install them at the screw hole positions, following the manufacturer’s instructions. 4 Using six field-supplied mounting screws and anchors (if applicable), attach the bracket to the wall.

The piping bundle that exits the unit and extends to the hole will need to be attached to the wall and will be visible inside the room. ‐‐ In relation to the bracket shown above, the unit is shipped with the drain hose connection on the right, the drain hose exits the unit on the left, and the refrigerant pipes are bent to exit on the left. Thus, positioning the hole to the left requires the least effort. If you position the hole to the right or below the unit, you will need to move the drain hose connection to the left and bend the pipes so that the hose and pipes exit to the right or bottom. See the figure in step 3 on page 12. English 11 Installation Level Center of indoor unit (B) Center of indoor unit (A) Indoor Unit Installation 2 Use a standard 65 mm hole saw to drill one hole at the selected location, at a 15° downward angle so that the drain hose will drain properly. •• The smaller‑diameter pipe is for the high‑pressure, two‑phase refrigerant. •• The larger‑diameter pipe is for the low‑pressure refrigerant vapor. Wall Drain hose Indoor unit 3 Two short refrigerant pipes are already attached to the air conditioner: Based on the hole location, determine where the piping bundle (drain hose, refrigerant pipes, and cables) will exit the unit. Left Right <Front view> <Side view> bottom Rear right or left NOTE Installation •• The left, right, or bottom exit will only be used if the hole is not positioned behind the unit. Step 2.3 Connecting the refrigerant pipes Connect indoor and outdoor units with field-supplied copper pipes by means of flare connections. Use insulated seamless refrigeration grade pipe only, (Cu DHP type according to ISO1337), degreased and deoxidized, suitable for operating pressures of at least 4200 kPa and for burst pressure of at least 20700 kPa. Under no circumstances must sanitary type copper pipe be used. IMPORTANT •• When installing the unit, always connect the refrigerant pipes first, followed by the electrical cables. For disassembly, always disassemble the electric cables before the refrigerant pipes. 12 English Drain hose Refrigerant Connection hose pipes (assembly pipe) In Step 2.2, step 3 you determined the exit position for the piping bundle. The unit has three knockouts available for the left, right, and bottom exits. When the bundle exits directly from the rear, none of the knockouts are used. 1 If the pipes will exit directly from the rear, skip to step 3. Otherwise, cut out the appropriate knockout piece (left, right, or bottom). 2 Use a razor knife to clean the cut edges (flashing). 3 The left exit is the only position that does not require bending the pipes. For other positions, bend the pipes so that they will exit in the selected exit position. ‐‐ The bending radius should be greater than 100 mm. ‐‐ Bend the smaller pipe gradually to prevent kinking. The larger pipe has a preinstalled spring bender to prevent kinking. ‐‐ Make sure that the pipes do not protrude from the back of the unit in a way that will make it difficult to attach the unit to the mounting bracket. ‐‐ For right and bottom exits, pull the pipes out through the selected knockout opening. For left exits, the piping connections will be made in the service space behind the indoor unit (under the cover panel). NOTE •• If you are using the right rear exit, the pipes should be long enough to extend through the wall without needing to connect the line set first. It may be easier to connect the line set outside of the building, after you have bundled the pipes and cables and passed the bundle through the wall. In this case, do not connect the line set now. Instead, complete Step 2.4 through Step 2.7, then go outside and connect the line set as described below. 4 Slowly remove the protective caps on the refrigerant pipe connections to relieve the nitrogen holding charge. 5 Connect the line set to each pipe. Step 2.4 Connecting the power and communication cables Flare nut Indoor outlet pipe 6 Hand-tighten the flare nuts to make sure that they do not become stripped. Liquid service port <High pressure> 7 Connecting pipe WARNING •• Do not modify the power cable in any way. Doing so may cause electric shock or fire due to poor connection, poor insulation, or current limit override. Make sure to comply with the technical standards of electrical installations and the wiring regulations in the local area. •• This appliance must be properly grounded. Do not ground the appliance to a gas pipe, plastic water pipe, or telephone line. Failure to comply may result in electric shock, fire, and explosion. 1 Gas service port <Low pressure> Torque the flare connections to the following values: (Unit: mm) Outer diameter Torque (N·m) ø 6.35 14–18 ø 9.52 34–42 ø 12.70 49–61 ø 15.88 68–82 CAUTION 8 Do not box in or cover the pipe connections. Make sure that the connections are accessible for testing later in the installation process and for future servicing. 9 Tape over the end of the pipes so that debris will not enter the piping when it is passed through the wall. The pipes will be insulated later in the installation process.

Test parts for the indoor unit Test parts for the indoor unit English 21 Installation 2 Installation Inspection and Testing Step 4.3 Evacuating the system CAUTION •• Because the system does not have filter driers, you must perform this triple evacuation procedure to remove all noncondensables and moisture from the system before charging. Failure to do so will result in reduced performance and shorter equipment life. The time required to perform each evacuation will depend on the capacity (CFM) of the vacuum pump used. 1 Install a micron vacuum gauge to the larger liquid/vapor line’s service port on the branch of a tee. 2 Install the red high‑side hose of an R-410A gauge manifold set to the smaller liquid/vapor line’s service port on the run of the tee. 3 Attach a vacuum pump to the common hose of the manifold set. 4 To ensure optimal performance, verify that the vacuum pump’s oil has been changed recently. 5 With the service port closed and the manifold gauge open, start the vacuum pump and make sure that the vacuum level drops below 4000 microns (as read on the micron gauge). If it is difficult to achieve a proper vacuum, a leak in the hoses is likely. Repair the leak(s) and/ or check performance of vacuum pump, then repeat this step. Installation 6 Open the service port to connect the system to the manifold. 7 Evacuate until 4000 microns is achieved, for at least 10 minutes. 8 Close the gauge manifold valve, shut off the vacuum pump, and remove the common hose. 9 Connect the hose to the nitrogen pressure regulator and bleed the hose by opening the end of the common hose closest to the manifold. 10 Open the high-pressure manifold valve and slowly bring the system pressure to atmosphere (50 kPa). 11 Close the manifold and nitrogen cylinder and remove the common hose. 22 English 12 Reconnect the common hose to the vacuum pump. Repeat steps 6 through 12, alternating between breaking the vacuum with dry nitrogen and evacuating, until system evacuation has occurred three times, to the following vacuum levels: Evacution Microns First 4000 Second 2000 Third 500 13 After evacuating to at least 500 microns for the third time, close the gauge manifold valve and wait 10 minutes, making sure that the vacuum level in the system does not decrease. If it does, a small leak is likely. Repair the leak and repeat the evacuation process. 3 Valve 4 15 minutes Vacuum Pump (Backward owing prevention) Liquid service port <Low pressure> 5 Liquid service port <High pressure> Step 4.4 Adding refrigerant (if needed) The outdoor unit is charged with sufficient R-410A refrigerant to support up to a 5 m line set. For lengths greater than 5 m, you must add 10g (for **09/12TSHZ***, **12TVH****) and 15 g (for **09/12TSEA***, **09TVH****, **09/12TSHC***, **18/24*******) of refrigerant per meter of additional length, after the lines are evacuated. 1 Calculate the additional refrigerant required: Additional grams of R-410A = (Total line set meter − 5) × 10 (for **09/12TSHZ***,**12TVH****) and 15 (for **09/12TSEA****09TVH****,**09/12TSHC***, **18/24*******) Step 4.5 Preparing the system for commissioning 1 Wrap the remaining refrigerant pipe lengths and connection points with foam insulation. 2 Wrap the unwrapped portions of the piping bundle with vinyl tape. 3 With the manifold gauge set still installed, open the isolation valves on the outdoor unit to connect the outdoor unit to the line set and indoor unit. 4 Remove the manifold set and vacuum gage. 2 Connect the common hose of the manifold gauge set to the inverted R-410A refrigerant cylinder. Step 4.6 Commissioning the unit 3 Place the refrigerant cylinder on a scale set to measure grams. The unit is commissioned using the Smart Install feature. 4 Open the valve on the tank. 5 At the manifold connection, bleed the refrigerant to remove any air that may be present in the common hose. 6 Open the gauge manifold and charge the system with the amount of refrigerant calculated in step 1. 7 Close the gauge manifold valve, close the valve on the refrigerant tank, and remove the common hose. Smart Install can be started only with the remote control. While Smart Install is running, you cannot operate the remote control. 1 Make sure that the air conditioner is in standby status (powered up with the controller in off mode). 2 Install batteries in the remote control. 3 (Power), (Mode), and (SET) Hold down the buttons on the remote control simultaneously for 4 seconds. 4 Wait until Smart Install succeeds or fails (approximately 7 to 13 minutes). ‐‐ While Smart Install is running: Display Installation Type Indoor unit indicator The progress is displayed as a number between 0 and 99 on the indoor unit display. ‐‐ When Smart Install succeeds: Smart Install ends with a ringing sound, and the air conditioner returns to standby status. ‐‐ When Smart Install fails: An error message is displayed on the indoor unit display, and Smart Install ends.
