Connecting the Piping

• Use caution when prepping the air handler to connect the copper line

set. The air handler will be be pressurized with dry nitrogen, which keeps

the unit free of moisture and indicates that the air handler doesn’t have

refrigerant leaks. When removing the plugs, the nitrogen will release. If

the nitrogen is not present in the air handler at time of installation, stop

installation and call Alpine’s technical support.

• Pair the pipe joint of the air handler with the flared end of the copper line

set. If the copper pipes aren’t already flared, please reference the Copper

Line Flaring section of this document (page 54).

• Tighten the union nut (compression fitting) by hand.

• Place the open-ended wrench on the pipe joint and place the torque

wrench on the union nut (compression fitting). Tighten the union nut

according to the chart below:

Draining

• The drain hose can be connected to either side of the air handler. There

is a plug on one end and a drain hose on the other. To properly drain the

indoor air handler, connect the drain tube to the same side as the copper

lines. Insert the drain plug in the other side.

• Insulate the Drain Tubing.
