Lift the unit preferably with a crane and 2 belts of at least 27 ft. long. 5. When lifting the unit with a crane, always use protectors to prevent belt damage and pay attention to the position of the unit s center of gravity. 6. After installation, remove the transport clasps attached to the large openings. 7. Bring the unit as close to its final installation position in its original package to prevent damage during transport. 3. Placing outdoor and indoor units. 4. install the refrigerant piping network as shown below: 1. The following materials should be used for all refrigerant piping: Materials: Deoxidized phosphorous seamless copper pipe or equivalent 2. The tips for insulation: Both Gas and liquid piping must be insulated. Materials: Glass fiber or heat resistant polyethylene foam Thickness: 1/2 inch or more Heat resistance: Gas pipe : 250 F or more / Liquid pipe : 160 F or more 1
25 UNDP - PAPP Building - Ramallah VRV III Technical Specifications September 2008 Wrap the insulation pipe with the finishing tape from bottom to top. 2
26 UNDP - PAPP Building - Ramallah VRV III Technical Specifications September Refnet joints: For gas and liquid branch pipes: 3
27 UNDP - PAPP Building - Ramallah VRV III Technical Specifications September After completing installation, be sure to open the valve as operating the unit with the valve shut breaks the compressor.. Use only R-410A from the solid pink cylinder. All field piping must be installed by a licensed refrigeration technician and must comply with relevant local and national regulations. USE CAUTION WHEN BRAZING REFRIGERANT PIPING do not use flux when brazing copper-to-copper refrigerant piping, particularly HFC refrigerant piping. Instead use phosphor copper brazing filler metal (B-Cu93P-710/795: ISO 3677) which does not require flux. Flux has an extremely negative effect on refrigerant piping systems and if chlorine-based flux is used, it causes pipe corrosion. Flux containing fluorine damages refrigerant oil. Installation tools: Make sure to use installation tools (gauge manifold charge hose, etc.) that are exclusively used for R-410A installations to withstand the pressure and to prevent foreign materials such as SUNISO mineral oils or moisture from mixing into the system. Screw thread and dimension specifications for flare nuts, service valves, and charging ports are different for R-410A than prior refrigerant types. Use a 2-stage vacuum pump with a non-return valve and make sure the pump oil does not flow back into the system while the pump is not working. After completing installation, be sure to open the valve. Operating the unit with the valve shut breaks the compressor. WHEN BRAZING REFRIGERANT PIPING: Do not use flux when brazing copper-to-copper refrigerant piping, particularly HFC refrigerant piping. Instead use phosphor copper brazing filler metal (B- Cu93P-710/795: ISO 3677) which does not require flux. Flux has an extremely negative effect on refrigerant piping systems and if chlorinebased flux is used, it causes pipe corrosion. Flux containing fluorine damages refrigerant oil. 4
28 UNDP - PAPP Building - Ramallah VRV III Technical Specifications September connecting the refrigerant piping: The local branch piping can be connected either forward, or to the sides and through the bottom as shown in the following figure: When multiple outdoor units are installed, an optional multi-piping kit is required to connect piping between units. Follow the installation manual s instructions accompanying the kit. Front connection: Remove the stop valve cover to connect. Side (bottom) connection: Remove the knockout holes on the bottom frame and route the piping under the bottom frame. 6. Pressurize the liquid, suction gas, and discharge gas pipes to 551 psi (do not pressurize more than 551 psi). If the pressure does not drop within 24 hours, the system passes the test. If the pressure drops, check where the nitrogen leaks from 7. Vacuum drying: Use a vacuum pump that can evacuate to 14.6 psi. Evacuate the system from the liquid, suction gas, and discharge gas pipes by using a vacuum pump for more than 2 hours and bring the system to 14.6 psi. After keeping the system under that condition for more than 1 hour, check if the vacuum gauge rises or not. If it rises, the system may either contain moisture inside or have leaks. if piping work is carried out during the rainy season or over a long period of time, rainwater may enter the pipe during work. Any possibility of moisture remaining inside the pipe requires the following action: After evacuating the system for 2 hours, pressurize the system to 7.25psi (vacuum break) with nitrogen gas and evacuate the system again using the vacuum pump for 1 hour 5
29 UNDP - PAPP Building - Ramallah VRV III Technical Specifications September 2008 To 14.6 psi (vacuum drying). If the system cannot be evacuated to 14.6 psi within 2 hours, repeat the operation of vacuum break and vacuum drying. After leaving the system in vacuum for 1 hour, confirm that the vacuum gauge does not rise. 8. Additional Refrigerant Charge Procedure: To learn the system settings for additional refrigerant charging, refer to the [Service Precaution] label attached on the back of the electric box lid in the outdoor unit. Fully open the suction gas line and discharge gas line stop valves. Be sure that the liquid line stop valve and valve A and valve B are left fully closed. and start the additional refrigerant charge operation. After the system is charged with a specified amount of refrigerant, press the confirmation button (BS3) on the PC-board (A1P) in the outdoor unit to stop the additional refrigerant charge operation. Immediately restore the stop valve to the following status. The test operation cannot be performed properly if the stop valve is not correct. 9. FIELD WIRING All field wiring and components must be installed by a licensed electrician and must comply with relevant local and national regulations. Be sure to use a dedicated power circuit. Never use a power supply shared by another appliance. This product s reversed-phase protection detector only works upon product startup and is designed to stop the product if an abnormality occurs. Replace two of the three phases (L1, L2, and L3) during reverse-phase protection circuit operation. Reversed-phase detection is not performed while the product is operating. If a reversed phase occurs during a momentary blackout and the power goes on and off while the product is operating, attach a local reversed-phase protection circuit. Running the product in reversed phase can break the compressor and other parts. Use copper conductors only. For connection wiring to outdoor-outdoor transmission F1- F2, outdoorindoor transmission F1-F2, use copper wiring (2*1.5mm). Refer to the Central Remote Controller s Installation Manual for its connection wiring. Use insulated wire for the power cord. 6
