3. TEST OF THE SYSTEM AND CONTROL OF THE AIR VOLUME TO THE OUTLET GRILLES The unit is prearranged to supply an external static pressure of about 5 mm. Too high resistances in the air distribution system can cause an exceedingly small air volume to the outlet grilles. This trouble can be solved by increasing the fan speed as follows: Open the cover of the electrical junction box. Take out the booster cable clamped in the box. (fig. 3-1) Disconnect the fan motor plug in the electrical box and inse

CAUTION (1) When linking outdoor units in a network (S-net link system), disconnect the terminal extended from the short plug (CN003, 2P Black, location: right bottom on the outdoor main control PCB) from all outdoor units except any one of the outdoor units. (When shipping: In shorted condition.) Otherwise the communication of S-net link system is not performed. For a system without link (no con- nection wiring between outdoor units), do not remove the short plug. (2) Do not install the inter-

Deburring 5. HOW TO PROCESS TUBING Before After The narrow tubing side is connected by a flare nut, and the wide tubing side is connected by brazing. 5-1. Connecting the Refrigerant Tubing Use of the Flaring Method Many of conventional split system air conditioners employ the flaring method to connect refrigerant tubes which run between indoor and outdoor units. In this method, the copper tubes are flared at each end and connected with flare nuts. Fig. 5-1 Flaring Procedure with a Flare Tool (1

Caution Before Connecting Tubes Tightly (1) Apply a sealing cap or water-proof tape to prevent dust or water from entering the tubes before they are used. Apply refrigerant lubricant here and here (2) Be sure to apply refrigerant lubricant to the match- ing surfaces of the flare and union before connect- Fig. 5-4 ing them together. This is effective for reducing gas leaks. (Fig. 5-4) (3) For proper connection, align the union tube and flare tube straight with each other, then screw in the flare

5-4. Taping the Tubes (1) At this time, the refrigerant tubes (and electrical wiring if local codes permit) should be taped together with armoring tape in 1 bundle. To pre- vent the condensation from overflowing the drain pan, keep the drain hose separate from the refrigerant tubing. Clamp (2) Wrap the armoring tape from the bottom of the Drain hose Insulated tubes outdoor unit to the top of the tubing where it enters the wall. As you wrap the tubing, overlap half of each previous tape turn. (3
