WIRING CONNECTION:
!All wiring and grounding must comply with the local Electric Codes.
!See the unit nameplate for electrical rating and use correct wire size to handle the minimum circuit ampacity required for the unit. Refer to Local Electric Codes for wire sizing.
!Always use a separate power line with circuit breaker for each air conditioner.
!Always ground the unit.
!Ensure that no wiring touches the tubing, motors or any other moving parts.
!Depending on the outdoor unit type, the number of
!Finally inspect all the electrical connections, including the factory wiring to ensure that all connections are tight.
EXTERNAL FINISHING OF PIPING
!After completing the installation of the refrigerant piping, drain pipe and wiring, bind them together into a bundle with tape at 4 inches to 8 inches (100 to 200 mm) intervals. Start from the bottom and work to the top. Keep the drainpipe at the bottom of the bundle.
!Do not fail to apply insulation to the joints and wrap them with tape. If the joints are not insulated, condensation could form on them, resulting in water leakage.
!Use saddles to secure piping in place so that it does not sway back and forth.
!Plug any open portions of the pass through hole with putty to ensure that no rain or wind can get inside.
!Finally, tidy up both the inside and outside and the installation process is complete.
