6-4. Taping the Tubes (1) At this time, the refrigerant tubes (and electrical wir- ing if local codes permit) should be taped together with armoring tape in 1 bundle. To prevent the con- densation from overflowing the drain pan, keep the drain hose separate from the refrigerant tubing. -
Page 80: Air Purging With A Vacuum Pump (For Test Run) Preparation
7. AIR PURGING Air and moisture in the refrigerant system may have undesirable effects as indicated below. ● pressure in the system rises ● operating current rises ● cooling (or heating) efficiency drops ● moisture in the refrigerant circuit may freeze and block capillary tubing ●... - Page 81 (3) Do a leak test of all joints of the tubing (both indoor and outdoor) and all service valves. Bubbles indicate a leak. Wipe off the soap with a clean cloth after a leak test. (4) After the system is found to be free of leaks, relieve the nitrogen pressure by loosening the charge hose connector at the nitrogen cylinder.
- Page 82 NOTE The required time in the above table is calculated based on the assumption that the ideal (or target) vacuum condition is less than –14.7 psig (–755 mm Hg, 5 Torr). (2) When the desired vacuum is reached, close the “Lo” knob of the manifold valve and turn off the vacuum pump.

In the following, automatic setting of indoor unit addresses is not possible if the compressors are not operating. Therefore perform this process only after completing all refrigerant tubing work.
- Page 92 Display during automatic address setting ● On outdoor main unit PCB * Do not short-circuit the automatic address setting pin (CN100) again while automatic address set- ting is in progress. Doing so will cancel the setting operation and will cause LEDs 1 and 2 to turn OFF.

Request concerning recording the indoor/outdoor unit combination Nos. After automatic address setting has been completed, be sure to record them for future reference. List the outdoor main unit system address and the addresses of the indoor units in that system in an easily visible loca- tion (next to the nameplate), using a permanent marking pen or similar means that cannot be abraded easily. -
