Pipe Cutting

Step 1: Cut Pipe

1. When preparing refrigerant pipes, take extra care to cut

and ﬂare them properly. This will ensure an airtight seal,

eﬃcient operation, and, minimize the need for future

maintenance.

2. Measure the distance between the indoor and outdoor

units.

3. Using a pipe cutter, cut the pipe a little longer than the

measured distance.

4. Make sure that the pipe is cut at a perfect 90° angle.

Refer to Fig. 2.9 for cut examples.

DO NOT deform pipe while cutting. Be extra

careful not to damage, dent, or deform the pipe

while cutting. This will drastically reduce the

heating eﬃciency of the unit.

Step 2: Remove burrs

Burrs can aﬀect the airtight seal of refrigerant piping

connection. They must be completely removed.

1. Hold the pipe at a downward angle to prevent burrs

from falling into the pipe.

2. Using a reamer or deburring tool, remove all burrs from

the cut section of the pipe. Refer to Fig. 2 .10

3. After removing burrs from cut pipe, seal the ends with

PVC tape to prevent foreign materials from entering the

pipe.
