1-3. Optional Copper Tubing Kit
Copper tubing for connecting the outdoor unit to the indoor unit is available in kits which contain the narrow and wide tubing, fittings and insulation. Consult your nearest sales outlet or A/C workshop.
1-4. Type of Copper Tube and Insulation Material
If you wish to purchase these materials separately from a local source, you will need:
1.Deoxidized annealed copper tube for refrigerant tubing as detailed in Table 2.
When cutting tubing, add approximately 12" to 16" (30 cm to 40 cm) to each tube length to reduce vibration between the air conditioning units.
Table 2
2.Foamed polyethylene insulation for the specified O.D. copper tubes as required to precise length of tubing. Wall thickness of the insulation should be not less than 0.3 in. (8 mm).
1-5. Field Wiring
Use insulated copper wire for field wiring. Wire size varies with the total length of wiring. Refer to
CAUTION Check local electrical codes and regulations before
obtaining wire. Also, check any specified instructions or limitations.
