3. Installation Process
3-1. Embedding the Tubing and Wiring
Do not connect tubes to locations that are embedded.
Be sure to bind refrigerant tubing and
The power cable must be obtained
# ... AWG (American Wire Gauge)
Be sure to apply the provided labels to both ends of the
Securely seal the end of embedded tubing with vinyl tape in order to prevent dirt or moisture entry.
In order to prevent insulation breakdown and ground faults, do not allow the wire ends to come in contact with rainwater, or be subject to dew condensation.
3-2. Use of the Flaring Method
Many of the conventional split system air conditioners employ the flaring method to connect refrigerant tubes which run between indoor and outdoor units. In this method, the copper tubes are flared at each end and connected with flare nuts.
3-3. Flaring Procedure with a Flare Tool
(1)Cut the copper tube to the required length with a tube cutter. It is recommended to cut approx. 12" to 20" (30 to 50 cm) longer than the tubing length you estimate.
(2)Remove burrs at the end of the copper tube with a tube reamer or file. This process is important and should be done carefully to make a good flare.
