12 OPTIONAL PARTS 1. REFRIGERANT PIPES Part No. PAC-05FFS-E PAC-07FFS-E PAC-10FFS-E PAC-15FFS-E 5m 7m 10m 15m Pipe length Pipe size OD Liquid:/ø9.52 Gas:/ø15.88 Connection method Indoor unit:Flared Outdoor unit:Flared Note 1.How to connect refrigerant pipes. Factory supplied optional piping contains refrigerant at above atmospheric pressure. As long as the connection takes no more than 5 minutes, no air will enter, and there will be no need for air purging.
3-3 HOW to connect program timer (1) Install the program timer next to the remote controller the same way as the remote controller is installed. (2) Connect the program timer and the remote controller with a 6-wire cable as shown in the figure below. NOTE: While the program timer is connected to the remote controller, the 24 hour ON/OFF timer on the remote controller will not operate.
4. CENTRALIZED REMOTE CONTROLLER Allows individual or combined control of up to 16 units. Part No. PAC-805RC 4-1 Dimensions 113 12 23.5 56.5 11 8 113 117 Unit:mm 117 4-2 Functions "ENGAGED" indicator When this indicator is lit, transmisson is in progress and all swiches are inoperative. DUAL / CENTRAL switch This change-over switch governs the operation of the accessory remote controller. "DUAL" Instructions from both the accessory remote controller and the centralized remote controller are valid.
4-3 Connection method (1) Connection in the power supply cord. 1. Connect the power supply cord to the power supply terminal-block and fix in-place with a tie-wrap. Connect a single phase 200V AC(220, 230, 240V)to AN . As E is the GND terminal,be sure to ground the earth wire. 2. Connect the transmission line to the transmission terminal-block and fix it in-place with a tie-wrap. Use a ø1.6 (AWG14)or above two-wire cable for the transmission line.
5. PROGRAM TIMER ADAPTER This adapter is needed when a program timer(PAC-815PT)or a centralised remote controller(PAC-805RC)is used. Part No.
6. TIMER ADAPTER This adapter is needed for system control and for operation via external contacts. Part No. PAC-SA89TA-E ORN 1 BRN 2 RED 3 7.
