Be careful when picking up and moving the indoor and outdoor units. Get a partner to help, and bend your knees when lifting to reduce strain on your back. Sharp edges or thin aluminum fins on the air conditioner can cut your fingers. When Installing ……………………………………………………………………... -
Page 3: General
1. General This booklet briefly outlines where and how to install the air conditioning system. Please read over the entire set of instructions for the indoor and outdoor units and make sure all accessory parts listed are with the system before beginning. 1-1. -
Page 4: Tubing Length

Page 5: Selecting The Installation Site
2. Selecting the Installation Site Indoor Unit AVOID: areas where leakage of flammable gas may be expected. places where large amount of oil mist exist. direct sunlight. locations near heat sources which may affect performance of the unit. locations where external air may enter the room directly. -
Page 6: Outdoor Unit
(Fig. 2-5) This unit is designed so that the fan of the outdoor unit runs at low speed when the air conditioner is operated at low outdoor air temperatures. When the outdoor unit is exposed to strong wind, the system pressure drops because of the freeze protector. -
Page 7: How To Install The Indoor Unit
Table 3-1 Length Type XS1852 (PNR-XS2432) 32-9/32 (820) 28-3/4 (730) (3) Determine the pitch of the suspension bolts using the supplied full-scale installation diagram. The diagram and table (Fig. 3-3 and Table 3-2) show the relationship between the positions of the suspension fitting, the unit, and the panel. -
Page 8: Placing The Unit Inside The Ceiling
3-3. Placing the Unit Inside the Ceiling (1) When placing the unit inside the ceiling, deter- mine the pitch of the suspension bolts using the supplied full-scale installation diagram. (Fig. 3-4) The size of the opening for the indoor unit can be confirmed by attaching the full-scale installation diagram beneath the unit. -
Page 9: Installing The Drain Piping
3-4. Installing the Drain Piping (1) Prepare standard hard PVC pipe (O.D. 1-3/64 in.) for the drain and use the supplied drain hose and hose band to prevent water leaks. The PVC pipe must be purchased separately. The transparent part allows you to check drain- age. -
Page 10: Checking The Drainage
3-5. Checking the Drainage After wiring and piping are completed, use the follow- ing procedure to check that the water will drain smoothly. For this, prepare a bucket and wiping cloth ready to catch and wipe up spilled water. Do not supply power to the unit until the tubing and wiring to the outdoor unit are completed. -
Page 11: Ceiling Panel
Ceiling Panel Never touch or attempt to move the air direction louver CAUTION by hand or you may damage the unit. Instead, use the remote control unit if you want to change the direction or air flow. 3-6. Before Installing the Ceiling Panel (1) Remove the air-intake grille and air filter from the ceiling panel. -
Page 12: Installing The Ceiling Panel
3-7. Installing the Ceiling Panel (1) Lift the ceiling panel and position it to align the panel hook with the panel catch of the indoor unit. NOTE The ceiling panel must be mounted in the correct direction. Note that the 2 catches of the panel differ in size. -
Page 13: Duct For Fresh Air
3-9. Duct for Fresh Air Air-intake chamber (including Duct connection box and flange) are attached to the indoor unit when used to take fresh outdoor air. High-performance filter or Super long-life filter can be also installed in the air-intake chamber. (1) SETUP PRIOR TO INSTALLATION When installing the high performance filter or super long-life filter, the parts and parts numbers of filters to be assembled with the air-intake chamber are listed below. - Page 14 (b) INSTALLING THE AIR-INTAKE CHAMBER Set the air-intake chamber to the indoor unit taking care not to set to the incorrect direction. (Fig. 3-17) Fasten the air-intake camber with the accessory screws. (M5 L125, 4pcs) (Fig. 3-17) (c) INSTALLING THE DUCT CONNECTION BOX Fasten the duct connection flange to the duct connection box with the accessory screws (M4 L12, 4 pcs.).

Page 16: Wired Remote Control Unit (Option)
Wired Remote Control Unit (Option) (1) To access the printed circuit board, remove the cover plate of the electrical component box. (2) Attach the remote control connectors securely to the mating connector pins on the printed circuit board. (3) Turn the R.C.U. switch from “WIRELESS” to “WIRED”. -
Page 17: Address Switches
5. Address Switches If you are installing one indoor unit or one group of indoor units in the same room, it is necessary for you to assign each unit its own address so that each can be operated by its own remote control unit. You assign the addresses by matching the switch position of each indoor unit with the switch position of its remote control unit. -
Page 18: Electrical Wiring
Electric Code: ANSI/NFPA70) before beginning. You must ensure that installation complies with all relevant rules and regulations. (8) To prevent malfunction of the air conditioner caused by electrical noise, care must be taken when wiring as follows: The inter-unit control wiring and the remote control wiring (option) should be wired apart from the inter- unit power wiring. -

Page 20: How To Connect Wiring To The Terminal
Loose wiring may cause the terminal to overheat or result in unit malfunction. A fire hazard may also exist. Therefore, ensure that all wiring is tightly connected. When connecting each power wire to the correspond- ing terminal, follow the instructions on “How to connect wiring to the terminal”... -
Page 21: How To Process Tubing
7. How to Process Tubing The narrow tubing side is connected by flare nut, and the wide tubing side is connected by brazing. 7-1. Use of the Flaring Method Many of the conventional split system air conditioners employ the flaring method to connect refrigerant tubes which run between indoor and outdoor units. -
Page 22: Precautions During Brazing
7-4. Precautions during Brazing Replace air inside the tube with nitrogen gas to prevent copper oxide film from forming during the brazing process. Do not allow the tubing to get too hot during the brazing process. The nitrogen gas inside the tubing may overheat, causing refrigerant system valves to become damaged. -
Page 23: Taping The Tubes
Important Because capillary tubing is installed in the outdoor unit, both the wide and narrow tubes of this air conditioner become cold. Therefore, to prevent heat loss and wet floors due to dripping of condensation water, both tubes must be well insulated with proper insulation material. -
Page 24: Air Purging
8. Air Purging Air and moisture remaining in the refrigerant system have undesirable effects as indicated below. Therefore, they must be purged completely. pressure in the system rises operating current rises cooling (or heating) efficiency drops moisture in the air may freeze and block capillary tubing water may lead to corrosion of parts in the refrigerant system Air Purging with a Vacuum Pump (for Test Run) - Page 25 (12) Test run the air conditioner. (See next page.) (13) While the air conditioner is running, apply liquid soap to check for any gas leaks around the service valves or caps.
