Cut the pipe and wring cable. • Measure the distance between the indoor and the outdoor unit.
- Page 24 1) Connection of Pipings 1. Remove the indoor tubing with the drain hose from the retainer clip. • Remove tubing holder and carefully, slowly pull the tubing away from the chassis. 1. Replace the tubing holder into original position. • Recommended additional Drain Hose.
- Page 25 6. Indoor unit installation • Hook the indoor unit onto the upper portion of installation plate. (Engage the two hooks of the rear top of the indoor Connecting cable unit with the upper edge of the installation plate.) Ensure the hooks are properly seated on the installation plate by moving it left and right.

Page 34: Air Purging
6. Air Purging Air and moisture remaining in the refrigerant system 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 35 Evacuation 1. Connect the charge hose end described in the preceding steps to the vacuum pump to evacuate the tubing and indoor unit. Confirm the “LO” knob of the manifold valve is open. Then run the vacuum pump. The operation time for evacuation varies with the tubing length and capacity of the pump.
