8 S4359128 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.
9 S4359128 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.
10 S4359128 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.

16 S4359128 ■ 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.
S4359128 17 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.
18 S4359128 6. Electrical Wiring 6-1. General Precautions on Wiring (1) Before wiring, confirm the rated voltage of the unit as shown on its nameplate, then carry out the wiring closely following the wiring diagram.
S4359128 19 ● Conduit's trade size for this unit is 1/2". The conduit can be purchased at a hardware store. ● The fuse located in the outdoor unit provides power supply protection and may blow when power is applied if the system has been incorrectly wired.
20 S4359128 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.
S4359128 21 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.
22 S4359128 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.
S4359128 23 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.
24 S4359128 CAUTION 8. Air Purging Air and moisture remaining in the refrigerant system have undesirable effects as indicated below. Therefore, they must be purged completely.
S4359128 25 (5) With the vacuum pump still running, close the “Lo” knob of the manifold valve. Then stop the vacuum pump. (6) With the accessory hex wrench, turn the valve stem on the narrow tube service valve counter-clockwise by 90 degress (1/4 turn) for 10 seconds, and then turn the stem clockwise to close it again.
26 S4359128 9. Test Run 9-1. Performing Test Run Be careful since the fan will start when performing Test Run. (1) The Operation Selector is located on the electrical component box inside the indoor unit. To access the Operation Selector, press the two latches of the air intake grille in the direction of the arrow to open the grille.
S4359128 27 9-3. Basic Function of the Service Valves The basic function of the service valves are given in Table 7 below. Action Narrow Tube Service Wide Tube Service Valve (2-Way) Valve (3-Way) 1826.
