Step 2. Tightening
- Align the center of the pipes and sufficiently
tighten the flare nut by hand.

Step 3. Preventing entering of foreign objects
- Plug the pipe through-holes with putty or
insulation material (procured locally) to fill up
all gaps as shown in right figure.
- If insects or small animals enter the outdoor
unit, it may cause a short circuit in the
electrical box.
- Finally, form the pipes by wrapping the
connecting portion of the indoor unit with
insulation material and secure it with two
kinds of vinyl tape. Ensuring thermal
insulation is very important.
